What is Cybersecurity Mesh? Operation Role Application

In today’s era of digital transformation, the boundaries of an enterprise’s traditional network are blurring, and IT infrastructure is becoming increasingly distributed. In such an environment, conventional approaches to cybersecurity are proving inadequate. Cybersecurity Mesh is the answer to these challenges – a security architecture that changes the way organizations protect their digital assets. Instead of building a single wall of defense around an entire organization, Cybersecurity Mesh creates smaller, individualized security perimeters around each access point.

What is Cybersecurity Mesh and why is it gaining importance?

Cybersecurity Mesh is a decentralized approach to digital security architecture that enables flexible, scalable and reliable security controls. Unlike the traditional model, which creates a single protective perimeter around an organization’s entire network, Cybersecurity Mesh defines security around an identity – be it a person, thing or service. This is a fundamental paradigm shift: security is no longer tied to a physical location, but follows digital assets and users wherever they are.

The growing importance of Cybersecurity Mesh is directly related to profound changes in the work environment and IT infrastructure. The shift to remote work has accelerated the change, making traditional corporate network boundaries obsolete. At the same time, the progressive adoption of cloud computing, microservices and IoT devices has made organizations’ digital assets increasingly distributed.

The key value of Cybersecurity Mesh lies in its ability to create a consistent security policy in a heterogeneous IT environment. Instead of managing a myriad of often unrelated security tools, organizations can implement a unified strategy that covers all resources, regardless of their location or the technology used.

What is Cybersecurity Mesh – in a nutshell:

Definition: Distributed security architecture model focused on identity instead of physical boundaries
Why it’s gaining importance: A response to the growing distribution of IT resources, remote working and the proliferation of devices
Key difference: security follows resources and users rather than being tied to location
For whom: Particularly relevant for organizations with distributed IT infrastructure and hybrid working model

What are the key components of the Cybersecurity Mesh architecture?

The Cybersecurity Mesh Architecture (CSMA) consists of four fundamental layers that work together to create a cohesive and comprehensive security system:

1 Security policy management plane: Is at the heart of the overall architecture. It enables the definition, implementation and enforcement of consistent security policies across an often heterogeneous IT environment. This layer is responsible for translating the organization’s overall security policies into specific configurations of individual security tools.

2 Identity plane: Serves as the foundation of access control. It includes authentication mechanisms, identity and privilege management, and context-based adaptive access control. It allows organizations to precisely define who has access to what resources, under what circumstances and for how long.

3 Consolidation and analysis plane: Collects data from all elements of the security infrastructure, providing a comprehensive view of the security status of the entire organization. This layer uses advanced analytics technologies to detect anomalies, identify potential threats and correlate security events.

4 Smart Automation Plane: Optimizes security processes by automating routine tasks such as responding to common incidents, security updates and compliance management.

What does this mean in practice?
Imagine that instead of one lock for the whole house, every room and drawer has its own smart lock. These locks communicate with each other, adjust security levels according to the situation and automatically respond to suspicious events. In addition, a central system manages all keys and decides who has access to specific rooms and when, depending on roles and context.

How is Cybersecurity Mesh different from traditional security solutions?

The traditional approach to IT security is based on the “castle and moat” concept, where an organization’s entire infrastructure is protected by a single, external security perimeter. This model assumes that everything inside the perimeter is trustworthy, while everything outside is potentially dangerous. This structure worked well in the days when IT resources were centralized and employees performed their duties exclusively from the office.

Cybersecurity Mesh fundamentally differs in its approach to defining security boundaries. Instead of creating a uniform perimeter around the entire organization, it introduces micro-perimeters around individual resources, users or applications. In the traditional model, once an attacker breaks through the external protection, he gains potential access to the entire internal network. In contrast, in the Mesh architecture, even after one element is compromised, other resources remain protected by their own security mechanisms.

Another major difference is how the principle of least privilege is implemented. Traditional solutions often use static privileges that, once granted, are rarely reviewed. Cybersecurity Mesh implements dynamic access control based on context, taking into account factors such as user location, time of day, device type or behavioral patterns.

Key differences between the traditional model and Cybersecurity Mesh:

The security frontier: Uniform perimeter vs. micro-perimeters around each resource
Trust model: Default trust within the network vs. Zero Trust (verify always)
Access control: Static vs. dynamic and contextual
Architecture: siloed vs. integrated and interoperable
Resilience: single point of failure vs. distributed protection

How does the Cybersecurity Mesh model work in practice?

On a practical level, the Cybersecurity Mesh functions as a multi-layered, decentralized security structure that dynamically adapts to changing conditions and threats. The foundation of this model is the Zero Trust approach, based on the principle of “never trust, always verify” – every attempt to access an organization’s resources must be subject to continuous verification, whether it comes from inside or outside the network.

In a practical deployment, Cybersecurity Mesh often starts with a central identity and access management (IAM) system, which becomes the core of the entire security architecture. This system integrates with a variety of security tools, such as web application security gateways (WAFs), intrusion prevention systems (IPS), endpoint protection solutions (EPPs) and user behavior monitoring and analysis tools (UEBAs).

Practical Scenario: An employee attempts to access sensitive financial data from a private laptop while in a coffee shop. Cybersecurity Mesh:

Verifies the identity of the employee (through multi-factor authentication)
Checks the security status of the device (current software, antivirus protection enabled)
Analyzes the context (location, time, untrusted public network)
Assesses the level of data sensitivity and user rights
Based on these factors, it makes a decision – it may grant limited read-only access, require additional verification, or deny access altogether under current conditions

This entire process is done in real time, automatically and transparently to the user, ensuring an optimal balance between security and usability.

What are the benefits of implementing Cybersecurity Mesh in an organization?

Implementing Cybersecurity Mesh architecture brings a number of tangible benefits to organizations that go beyond the traditional aspects of IT security:

1 Improved protection for distributed assets: Cybersecurity Mesh provides consistent security for all digital assets, regardless of their location – whether in the local data center, public cloud, or on employees’ mobile devices. This flexibility is key in today’s highly distributed IT environment.

2 Increased Operational Flexibility: Organizations can adapt faster to changing business conditions without compromising on security. Employees can securely work remotely, use their own devices (BYOD) and access resources from any location, while being subject to appropriate security controls.

3 Cost optimization: Target security investments more precisely where they are needed most, rather than spending on redundant, overlapping solutions. Additionally, automating routine security tasks reduces the burden on IT teams and allows them to focus on more strategic initiatives.

4 Better visibility and risk management: A holistic view of an organization’s entire security environment enables faster detection of threats, better prioritization of actions and more informed decisions about security investments.

For the CIO/CSO: Cybersecurity Mesh enables a consistent security strategy across a heterogeneous IT environment, while supporting innovation and business flexibility. It enables better security budget allocation and can lower the total cost of ownership (TCO) of security solutions.

For IT professionals: The architecture eliminates security silos, makes it easier to automate routine tasks and provides better visibility into threats across the environment. Reduces the time required to respond to incidents and manage security policies.

When might Cybersecurity Mesh not be the optimal solution?

While Cybersecurity Mesh offers numerous benefits, there are scenarios in which it may not be the most appropriate choice:

For small organizations with simple infrastructure: Companies with a small IT team, a limited number of systems and a centralized infrastructure may not experience the full benefits of implementing a comprehensive Cybersecurity Mesh architecture. The cost and complexity of implementation may outweigh the potential benefits.

Organizations with limited IT budgets: A full Cybersecurity Mesh implementation requires a significant investment in technology, integrations and training. For companies with limited financial resources, a more incremental approach to security modernization may be a wiser choice.

Environments with high isolation requirements: Some regulated sectors (e.g., military, selected government institutions) may have requirements that favor physical network segmentation and system isolation over the more flexible but potentially more complex Cybersecurity Mesh model.

Alternative approaches: Instead of a full Cybersecurity Mesh deployment, organizations can consider:

Gradual implementation of Zero Trust elements, starting with the most critical resources
Hybrid models combining traditional perimeter protection with selective application of micro-segmentation
Secure Access Service Edge (SASE) solutions, which may be less comprehensive but easier to implement in some scenarios

Each organization should conduct a detailed analysis of its needs, existing infrastructure and available resources before deciding to implement Cybersecurity Mesh.

Why is Cybersecurity Mesh the answer to the challenges of working remotely?

The global shift toward remote and hybrid work has presented IT departments with unprecedented security challenges. Traditional solutions based on perimeter protection have proven inadequate in the face of a mass exodus of employees outside of physical offices.

Cybersecurity Mesh addresses these challenges perfectly with its decentralized nature. Unlike traditional solutions, it does not require employees to connect to the corporate network via VPN to securely access resources. Instead, each resource is individually protected by its own security “cocoon” that verifies each access attempt regardless of the user’s location.

A key element of Cybersecurity Mesh in the context of remote work is the ability to assess the security status of endpoint devices before granting access to corporate resources. In a traditional office environment, the IT department has full control over the configuration and status of devices. In a remote working model, employees often use private computers or unmanaged mobile devices, which creates additional risk.

How does Cybersecurity Mesh support security in cloud environments?

Migration to the cloud has become a key part of the digital transformation of enterprises, but it introduces new dimensions of complexity in security management. Most organizations are using cloud services, often combining solutions from different vendors in a multi-cloud strategy. This diversity of environments creates significant challenges for traditional security models.

Cybersecurity Mesh addresses cloud security challenges perfectly with its ability to create a consistent security layer across different cloud platforms. Instead of implementing separate policies and controls for each cloud provider, organizations can define uniform security policies that are then enforced consistently across all environments.

What does this mean in practice?
Imagine your organization using AWS for data processing, Microsoft Azure for business applications and Google Cloud for analytics. Instead of configuring and managing three separate security systems, Cybersecurity Mesh allows you to define uniform policies (e.g., “only verified users from trusted devices can access financial data”) and automatically enforce them across all environments.

A key element of Cybersecurity Mesh in the context of the cloud is advanced identity and access management, which enables precise control over who can access cloud resources and under what circumstances. In the traditional model, permissions are often granted based on static roles, which can lead to excessive privileges. Cybersecurity Mesh introduces dynamic access control based on context.

How does Cybersecurity Mesh manage user identity and access?

Identity and Access Management (IAM) is the foundation of the Cybersecurity Mesh architecture, transforming traditional static access control models into dynamic, contextual and intelligent security systems. Unlike conventional solutions, which rely on a simple distinction between internal and external users, Cybersecurity Mesh implements a Zero Trust model, in which every access attempt is subject to verification.

Multi-level authentication: Cybersecurity Mesh goes far beyond traditional passwords, integrating biometrics, hardware tokens, digital certificates and verification via mobile devices. Moreover, it introduces adaptive authentication that adjusts security requirements according to the level of risk – for example, accessing critical financial data from an unknown location may require additional forms of verification.

Dynamic privilege management: Instead of static, permanently assigned permissions, Cybersecurity Mesh introduces a contextual access system, where permissions can change dynamically depending on the situation. For example:

System administrator can only have full privileges during business hours
Access to sensitive patient data in the hospital may be limited only to staff currently caring for the patient in question
Permission to modify production code can be activated only after approval by a second team member

Identity federation: Cybersecurity Mesh enables the unification of user identities in a heterogeneous IT environment. Instead of having separate accounts for different systems and platforms, users can use a single, consistent identity, managed centrally. This dramatically simplifies the lifecycle management of user accounts and reduces the risks associated with “abandoned” accounts of former employees.

How to effectively implement Cybersecurity Mesh in a company?

Successful implementation of Cybersecurity Mesh requires a systematic, multi-step approach. Here is a practical roadmap:

Phase 1: Preparation (2-3 months)

Assess the current state: Conduct an inventory of all IT assets, mapping data flows and identifying critical assets.
Gap analysis: Identify areas where current safeguards are inadequate in the context of the Zero Trust model.
Prioritization: Identify the most critical resources and users that should be included in the first phase of implementation.

Phase 2: Building the foundation (3-6 months)

Centralize identity management: Implement or modernize IAM systems as the foundation of the overall architecture.
Data inventory and classification: Determine where the data is located, its level of sensitivity, and who should have access to it.
Network segmentation: Introducing microsegmentation as a first step toward granular access control.

Phase 3: Architecture expansion (6-9 months)

Implementing adaptive access control: Defining access policies based on context and risk.

What are the most common challenges when implementing Cybersecurity Mesh?

Cybersecurity Mesh implementation, despite its advantages, comes with a number of challenges that organizations should consider before starting the transformation:

Integration of existing systems: Most organizations already have an extensive security solution environment that has evolved organically over the years. Integrating these often incompatible systems into a cohesive Cybersecurity Mesh architecture can be very complex. Some legacy systems may not offer the modern APIs or integration capabilities required by this architecture.

Balancing security with user convenience: Implementing advanced verification mechanisms can lead to additional steps in the authentication process, which users may perceive as cumbersome. Finding the right balance between stringent controls and smooth business processes is a key challenge.

Management complexity: Cybersecurity Mesh requires central coordination of distributed security components, which can be difficult in large, decentralized organizations. Implementing a unified security policy in an environment that spans different departments, geographic locations and IT systems requires sophisticated orchestration tools and clearly defined processes.

Shortage of qualified professionals: Implementing and managing a Cybersecurity Mesh architecture requires interdisciplinary expertise combining traditional network security, identity management, cloud security, data analytics and process automation. Such versatile specialists are difficult to find on the job market.

Regulatory compliance: Security architecture transformation must be carried out in full compliance with applicable regulations. This is particularly complex in organizations that operate globally and are subject to different jurisdictions and regulatory regimes.

Cost and implementation time: A full Cybersecurity Mesh implementation requires a significant investment, not only in technology, but also in training, integration and potential process reorganization. A typical implementation can take 12 to 24 months, depending on the size and complexity of the organization.

How does Cybersecurity Mesh affect IT security costs?

The impact of Cybersecurity Mesh on the economics of IT security is complex and multidimensional. It is useful to have realistic expectations about both the outlay and potential financial benefits:

Initial capital expenditure

Implementing the Cybersecurity Mesh architecture comes with significant upfront costs, which include:

Purchase or upgrade key components (IAM systems, analytical tools, automation platforms)
Costs of integrating existing systems with the new architecture
Expenses for consultants and implementation specialists
Training for IT staff and end users

For a medium-sized organization (500-1,000 employees), the initial outlay can range from PLN 250,000 to PLN 750,000, depending on the complexity of the environment and the maturity of existing security solutions.

Long-term economic benefits

In the long run, a well-implemented Cybersecurity Mesh architecture can bring tangible savings:

Operational Optimization: Integrating distributed security solutions into a cohesive platform eliminates duplicate functionality and better leverages existing investments. Organizations can reduce the number of separate security tools, resulting in lower licensing, support and administration costs.

Reduction of incident costs: More effective detection and neutralization of threats translates into a lower number and scale of security incidents. Given that the average cost of a data breach in an organization can run into the millions (taking into account direct costs, reputational damage, regulatory penalties), even a small reduction in risk can result in significant savings.

IT team efficiency: Automation of routine security tasks allows better use of human resources. Security analysts can focus on more complex tasks instead of wasting time on manual processes and responding to false alarms.

Typical ROI trajectory

Year 1: Negative ROI – implementation costs dominate, while benefits are just beginning to materialize
Year 2-3: Breaking point – operational benefits and risk reduction begin to offset initial outlay
Year 4+: Positive and growing ROI – full benefits of process optimization and better protection against threats

Organizations should realistically look at investing in Cybersecurity Mesh as a long-term strategic endeavor, rather than as a quick fix to reduce IT costs.

How to measure the effectiveness of Cybersecurity Mesh deployment?

Measuring the effectiveness of a Cybersecurity Mesh implementation requires a comprehensive approach that includes both technical and business aspects. Here are the key metrics and evaluation methods:

Security operational metrics

Time to detect an incident (MTTD): How much time elapses from the time a security breach occurs until it is detected. An effective Cybersecurity Mesh implementation should significantly reduce this time.
Incident response time (MTTR): How quickly an organization responds to a detected threat. Advanced automation within the Mesh architecture should speed up this process.
False alert rate: The percentage of security alerts that turn out to be false threats. With better contextualization and analysis, Cybersecurity Mesh should reduce this rate.

Risk management metrics

Reducing the attack surface: Assessing the reduction of potential attack vectors, such as by eliminating unnecessary privileges or service exposures.
Number of critical vulnerabilities: Monitor the number of unpatched critical vulnerabilities in the IT infrastructure.
Level of regulatory compliance: The degree to which an organization complies with regulatory requirements (GDPR, FSC, ISO 27001, etc.).

User experience metrics

Access time: How long users have to wait to access needed resources.
Number of requests to the helpdesk: Number of access issues reported by users.
User satisfaction: Measured through regular surveys and feedback.

Business metrics

Total cost of ownership (TCO): The full cost of IT security, including both technology and human resource expenses.
Incident costs: Direct and indirect losses associated with security breaches.
Business Productivity: The impact of implementation on business process efficiency and innovation.

Practical measurement tools:

Simulated attacks and penetration testing
Automated vulnerability scanners
Privilege reviews and access audits
Dashboards and reports from SIEM systems
User satisfaction surveys
Analysis of logs and historical data

The key to effective measurement is to establish baselines before implementation and regularly monitor trends over time. This allows you to objectively assess the real impact of the transformation on the organization.

What are the forecasts for Cybersecurity Mesh development in the coming years?

The evolution of the Cybersecurity Mesh in the coming years will be shaped by a number of technological, business and regulatory factors:

Deeper integration of artificial intelligence

As AI technology evolves, Cybersecurity Mesh will increasingly rely on advanced machine learning algorithms. Future implementations will use AI to:

More precise identification of anomalies and potential threats
Predictive detection of threats before they cause damage
Autonomous response to typical attack scenarios
Dynamically adjust security policies in response to changing behavioral patterns

Integration with DevSecOps

Cybersecurity Mesh will be increasingly integrated into development and operational processes. Security will become an integral part of the software development lifecycle, rather than a separate step added at the end. This will allow:

Automatically check code for vulnerabilities at the development stage
Defining and enforcing security policies as code
Continuous safety validation in production environments
Faster response to newly discovered vulnerabilities

Autonomous cyber security

In the long term, Cybersecurity Mesh is evolving into fully autonomous security systems that will:

Independently detect and neutralize threats
Adapt to new types of attacks without human intervention
Automatically optimize security configurations
Anticipate and prepare for potential threats

Impact of regulation

Tightening data protection and cybersecurity regulations will continue to drive Cybersecurity Mesh adoption. Organizations will look for solutions that make it easier to comply with regulations such as:

NIS2 in the European Union
Sectoral requirements for financial institutions, healthcare and critical infrastructure
International security standards such as ISO 27001 and the NIST Cybersecurity Framework

Support for new work models and technologies

Cybersecurity Mesh will evolve to support new working models and technologies, such as:

Augmented reality (AR/VR) in corporate environments
Internet of Things (IoT) in industrial and consumer applications
Edge computing and data processing at the network edge
Increasingly distributed work models, going beyond traditional remote work

Why is Cybersecurity Mesh considered the future of cyber security?

Cybersecurity Mesh is widely recognized as the future of cybersecurity for several key reasons:

Fundamental compatibility with IT evolution: Today’s IT infrastructure reality is dramatically different from that of a decade ago. Resources are dispersed among local servers, multiple clouds and endpoint devices, and work is done from any location, on a variety of devices. The traditional perimeter approach simply does not match this reality.

Holistic Risk Management: Cybersecurity Mesh enables comprehensive protection that is better suited to today’s threats, especially multi-vector attacks. Integration of different security layers and centralization of management allow for more effective identification of complex threats.

Adaptability to a changing threat landscape: Unlike monolithic, hard-to-modify security architectures, Cybersecurity Mesh is based on a modular, component-based approach. This enables incremental innovation and adaptation to new types of threats.

Cybersecurity Mesh as a Necessity, Not Just an Option
In a world where remote working has become the norm rather than the exception, where organizations use an average of 5-10 different cloud solutions, and where the number of IoT devices is growing exponentially, the traditional approach to security is not only ineffective – it is becoming unworkable. Cybersecurity Mesh is no longer just an optional enhancement – it is becoming a business necessity for many organizations.

Supporting digital transformation: Cybersecurity Mesh eliminates the traditional trade-off between security and innovation. With more granular and adaptive controls, organizations can securely deploy new technologies and business models without unnecessary restrictions.

Operational flexibility: In an uncertain business world, the ability to quickly adapt to changing conditions is becoming a key competitive advantage. Cybersecurity Mesh enables you to work securely from anywhere, on any device, which is invaluable in today’s dynamic business environment.

How does Cybersecurity Mesh support compliance with regulations and security standards?

Cybersecurity Mesh offers organizations advanced capabilities to support compliance with regulations and security standards, which is becoming critically important in the face of an increasingly complex regulatory landscape.

Centralize the management of security policies

A key element of Cybersecurity Mesh in terms of compliance is the ability to define and automatically enforce security policies that reflect regulatory requirements. Instead of manually configuring each system or application, organizations can create central policies that are then translated into specific configurations for various components of the IT infrastructure.

Practical example: an organization can define a central policy for storing personal data that complies with RODO/GDPR (e.g., “personal data must be encrypted and accessible only to authorized personnel”), which is automatically enforced across all systems – from local databases to cloud applications to employee mobile devices.

Streamlining audit and verification processes

Cybersecurity Mesh significantly streamlines audit and compliance verification processes. Centralizing security management enables:

Comprehensive insight into the compliance status of the entire organization
Automatic generation of reports for auditors
Quick identification of potential security vulnerabilities
Tracking the history of access to sensitive data

This dramatically reduces the time and cost involved in preparing for audits and increases confidence that the organization meets all required standards.

Precise management of personal data

In the context of GDPR and similar data protection regulations, Cybersecurity Mesh makes it possible:

Implement the principle of data minimization through precise access control
Track and document all operations on personal data
Automatic enforcement of data retention periods
Quickly exercise the right to be forgotten through central data management

Support for industry standards

Cybersecurity Mesh supports compliance with popular security standards, such as:

NIST Cybersecurity Framework: the Mesh architecture directly addresses all five of the Framework’s key functions: Identification, Protection, Detection, Response and Recovery.

ISO 27001: Centralized policy management and security control automation facilitates the implementation and maintenance of an ISO 27001-compliant information security management system.

PCI DSS: For organizations that process payment card data, Cybersecurity Mesh enables them to accurately segment their payment environment, restrict access to card data, and provide comprehensive monitoring.

Regulation vs. Cybersecurity Mesh – Recommendations:

Start by mapping regulatory requirements to specific security policies
Use central policy management to ensure consistency across all systems
Automate compliance reporting and identify security vulnerabilities
Engage compliance experts early in the design of the Mesh architecture
Regularly test and verify the effectiveness of compliance mechanisms

How does Cybersecurity Mesh integrate with existing IT infrastructure?

Integrating Cybersecurity Mesh into existing IT infrastructure is a key aspect of successfully implementing this architecture. Unlike some revolutionary approaches, Cybersecurity Mesh is designed to allow for incremental, evolutionary implementation in heterogeneous IT environments.

API gateways and abstraction layers

A key element of integration is API gateways (API gateways) and abstraction layers, which act as intermediaries between the central management platform and the various components of the security infrastructure. These components translate unified security policies into specific configurations of individual tools and systems.

Practical approach: Instead of forcing the replacement of existing solutions, organizations can create connectors and adapters that enable communication between legacy systems and the new architecture. In many cases, it is possible to retain up to 70-80% of existing security tools, significantly reducing the cost and complexity of implementation.

Integration with cloud solutions

Cybersecurity Mesh offers advanced integration capabilities with major cloud platforms (AWS, Azure, Google Cloud) through native connectors and APIs. This allows you to:

Consistent identity and access management in hybrid environments
Uniform enforcement of security policies across clouds
Central monitoring and security analytics covering all environments

Identity and access management systems

Cybersecurity Mesh does not require replacing existing IAM solutions, but rather extends and enhances their capabilities. For example:

Existing Active Directory can be integrated with modern identity solutions
Traditional SSO mechanisms can be supplemented with adaptive authentication
Entitlement management systems can be enhanced with contextual risk analysis

Network infrastructure

In the context of network infrastructure, Cybersecurity Mesh offers the ability to integrate with existing solutions through security virtualization and software-defined networking. Instead of replacing physical network devices, organizations can overlay virtual security layers that extend the capabilities of existing infrastructure.

Monitoring and event management systems

Integration with SIEM (Security Information and Event Management) systems is another key aspect of Cybersecurity Mesh implementation. Existing SIEM solutions can be enhanced with:

Identity and access context that helps interpret security events
Advanced behavioral analytics that identifies subtle anomalies
Automatic correlations between events from different environments

A phased approach to integration

A phased approach to integration is recommended, starting with:

Centralize identity management as the foundation of the entire architecture
Integrate key business applications and the most sensitive resources
Gradual expansion to more systems and resources
Evolutionary migration of legacy systems when the natural moment comes to replace them

This gradual process allows the benefits of Cybersecurity Mesh deployment to be balanced against operational realities and budget constraints.
