A revolution in the way we work has become a reality. The model where one hundred percent of employees came to one central office every day has become a thing of the past for many companies. It has been replaced by remote and hybrid work, offering flexibility and access to talent from around the world. Our “office” has ceased to be a building and has become a distributed ecosystem of laptops in home living rooms, smartphones in coffee shops and tablets on trains. This transformation, while hugely beneficial for business, has at the same time completely destroyed the traditional cyber security model.
For decades, we built our defenses based on the concept of a “castle and moat” - a heavily fortified network perimeter that separated the “trusted” inside from the “hostile” outside world. Remote and hybrid work has torn down these walls. The network perimeter has stretched to encompass thousands of home Wi-Fi networks over which we have no control. Each employee and his or her device has become a small, separate “island” of corporate infrastructure. In this new distributed reality, the question is no longer “how do we protect our office?” but “how do we protect our people and our data, no matter where they are?”.

How has remote and hybrid working fundamentally changed the cyber threat landscape?
The massive shift to remote and hybrid work has created ideal conditions for cybercriminals to attack, opening up a number of new vectors and amplifying existing risks.
Blurring and disappearance of the network circuit: This is the most important change. There is no longer a single, easily defensible “gateway.” Instead, a company has hundreds or thousands of small, distributed “entrances” to its infrastructure. Each home Wi-Fi becomes a de facto part of the company’s network, but is completely out of the control of the IT department.
The rise of endpoints: An employee’s laptop and smartphone are no longer just a tool for working inside a secure office. They have become self-contained, fully functional branches of the company, with access to critical data, but operating in a potentially hostile environment. Securing them has become absolutely crucial.
Escalating social engineering attacks: In a remote environment, where face-to-face, in-person interaction is lacking, employees are much more susceptible to phishing attacks and other forms of manipulation. An email from a supposed “boss” with an urgent order is more difficult to verify when you can’t just walk up to his desk and ask.
Exploitation of unsecured home networks: Home Wi-Fi networks are often poorly secured, use default passwords, and have dozens of unsecured IoT devices (TVs, smart speakers) connected to them, which can become a beachhead for attackers.

What are the biggest risks of working from a home unsecured Wi-Fi network?
An employee’s home Wi-Fi network is an environment over which the company has virtually no control, and which becomes a de facto extension of the corporate network. This creates a huge risk.
Poor router security: Most home routers are configured once, at installation, and never updated again. They often run outdated software with publicly known vulnerabilities, use default administrator passwords or weak, easy-to-crack Wi-Fi passwords. For an attacker, taking control of a home router is often trivially easy.
Man-in-the-middle attacks: An attacker who has compromised a home router gains the ability to eavesdrop on and manipulate all Internet traffic passing through that network. He can intercept unencrypted data, swap websites with fake ones to steal credentials, or inject malicious code.
Unsecured IoT devices: Dozens of other poorly secured devices - from televisions to smart light bulbs to children’s toys - often operate on the same network as a company laptop. Compromising one of these devices can give an attacker a foothold inside the home network, from which he can then launch an attack on a much more valuable target - an employee’s laptop.
Why is ZTNA (Zero Trust Network Access) a better solution than a traditional VPN in a hybrid model?
For years, VPN has been the standard for remote access. However, in the hybrid work model, its drawbacks are becoming more apparent. A VPN, once authenticated, lets an employee’s device “inside” the corporate network, granting it a broad default level of trust. If an employee’s laptop or home network has been compromised, the VPN becomes an open highway for an attacker straight into the heart of the company’s infrastructure.
ZTNA (Zero Trust Network Access) is a modern alternative that is ideally suited to the realities of remote work. ZTNA is based on the principle of “never trust, always verify” and completely reverses the logic of VPNs:
-
Application access, not network access: The user is never “allowed into the network.” Instead, he or she is given granular, encrypted access only to those applications to which he or she has explicit permissions.
-
Continuous verification: with each access attempt, ZTNA verifies not only the user’s identity, but also the security status of his or her device. If the device is not compliant (e.g., has antivirus disabled), access may be blocked.
-
Hidden attack surface: Applications protected by ZTNA are invisible from the public Internet, drastically reducing the attack surface.
ZTNA provides a much higher level of security, while often offering better performance and comfort than a traditional, overloaded VPN.
Key challenges and solutions in hybrid work security
| Challenge | Risks | Key solution |
|---|---|---|
| Unsecured home network | Man-in-the-middle attacks, eavesdropping on traffic, attacking a laptop from other infected devices on the same network. | Always use a VPN or (better) ZTNA connection. Educate employees on basic home router security. |
| Private devices (BYOD) | Lack of control over the security status of the device, risk of data leakage, inability to remotely delete company data. | Implement an MDM/UEM platform with containerization functionality that separates corporate and private data. |
| Access to company applications | Broad, network-based access via VPN poses the risk of lateral traffic if the end device is compromised. | Migrate from VPN to Zero Trust Architecture (ZTNA), which provides granular, identity-based access to applications. |
| Loss/theft of device | Physical access to the device gives the attacker time to try to breach security and gain access to the data. | Enforcing full disk encryption (FDE) and strong passwords/biometrics. Having the ability to remotely wipe data (remote wipe). |
What role do MDM/UEM platforms play in securing laptops and smartphones?
In an environment where we no longer control the network, control of the endpoint device (endpoint) becomes absolutely crucial. This is where MDM (Mobile Device Management) platforms and their more modern form, UEM (Unified Endpoint Management), such as Microsoft Intune, come to the rescue.
These systems allow IT to centrally manage and enforce security policies on an entire fleet of laptops and smartphones, regardless of where they are located. With MDM/UEM, a company can:
-
Enforce key security features: Remotely enable and manage disk encryption (BitLocker, FileVault), require strong passwords and automatic screen lock.
-
Ensure the “health” of the device: Ensure that antivirus is always installed and updated on devices, and that security patches are installed in a timely manner.
-
Control applications: Distribute needed company applications and block the installation of unauthorized, potentially dangerous software.
-
Remote response: If a device is lost or stolen, an administrator can remotely lock it or wipe all company data from it (remote wipe).
Implementing an MDM/UEM platform today is the absolute foundation for securely managing a distributed team.
Why is building awareness and “healthy paranoia” in remote workers so crucial?
Technology is essential, but in a distributed work environment where there is a lack of direct supervision and support from colleagues behind the desk, the vigilance and awareness of the worker himself becomes more important than ever. The remote worker must become a self-reliant, intelligent security “sensor.”
Attackers are well aware that a person working from home is more susceptible to manipulation. They may be distracted, and it is more difficult to verify a suspicious request. Therefore, the intensity and sophistication of phishing and vishing attacks targeting remote workers has increased dramatically.
It is essential to implement an ongoing awareness-building program that goes beyond annual formal training. This program should include:
-
Regular, realistic phishing simulations that teach threat recognition in practice.
-
Simple and clear guidelines on how to act if you receive a suspicious message (e.g., “Report it to IT, even if you’re not sure. It’s better to report too much than not enough.”).
-
Education on basic digital hygiene at home, such as securing your home Wi-Fi network and not using your company laptop for personal use.
-
Building a “healthy paranoia” and “zero trust” culture about unexpected requests, especially those for money or data.
