Cybersecurity certifications: Which ones really build value and competence in a team?

In the dynamic and highly competitive world of cyber security, where knowledge and skills become obsolete at a rapid pace, professional certifications play a key role. They provide a standardized and globally recognized proof of competence, a kind of “common language” that allows employers to verify the knowledge of candidates and customers to assess the qualifications of service providers. For professionals themselves, certifications are career milestones, confirming their expertise and commitment to continuous improvement.

However, the certification market is a real jungle, full of hundreds of acronyms and promises. For IT leaders and managers who want to invest wisely in the development of their teams, the key question becomes: which certifications actually translate into real, practical skills and bring value to the organization, and which are just expensive “paper”? Choosing the right certification path is a strategic decision. This article is a guide to the most important and highly regarded certifications in the industry to help you understand their importance, differences and the value they bring to your team.

Why are certifications in cyber security so important for both employees and employers?

In an industry as dynamic as cybersecurity, where formal, standardized university education pathways are lacking, certifications serve as a key mechanism for verifying and standardizing knowledge.

For an employee, earning a recognized certification is a powerful career development tool. It validates his knowledge and skills in the eyes of current and future employers, often opening the door to more advanced roles and higher salaries. The process of preparing for the exam is extremely valuable in itself – it forces you to structure your knowledge, learn best practices, and go beyond your day-to-day responsibilities.

For the employer, team certifications bring a number of benefits. First, they are an assessment and recruitment tool. They allow the employer to quickly filter out candidates and verify their baseline level of knowledge. Second, they are a guarantee of quality for customers. A security services company whose team can boast certifications such as OSCP or CISSP builds trust and demonstrates that its competence is in line with the highest industry standards. Third, investing in employee certification is an effective way to motivate, develop and retain employees within the company.

What are the main categories of certificates and how do they differ from each other?

The world of certifications can be broadly divided into several major categories that correspond to different roles and career paths in cyber security. Understanding this division is key to choosing the right certification.

Management and strategic certifications: These focus on the “big” picture – security program management, risk, compliance and strategy. They are designed for security managers, future CISOs, auditors and consultants. The exams are usually theoretical and verify broad knowledge and experience. The most important representatives are CISSP and CISM.

Technical/Offensive Certifications: These focus on practical, “offensive” skills related to security testing, hacking and vulnerability finding. They are designed for pentesters, security analysts and Red Team members. Exams in this category often take a hands-on form. Key players include OSCP and CEH.

Technical/Defensive Certifications: These focus on skills related to building and operating defensive systems, incident response and post-incident analysis (forensics). They are designed for SOC analysts, security engineers and Incident Response specialists.

Auditor Certifications: These focus on the methodology and process of auditing information security management systems against specific standards. The most important example is the ISO/IEC 27001 Lead Auditor.

What is a CISSP (Certified Information Systems Security Professional) and who is it for?

The CISSP (Certified Information Systems Security Professional), offered by the (ISC)² organization, is undoubtedly one of the most recognized and respected certifications in the entire IT industry. It is often referred to as the “gold standard” for experienced cybersecurity professionals and managers.

The CISSP is not a deeply technical certification. It is extremely broad and strategic, and is designed to verify a candidate’s comprehensive knowledge of eight key information security domains, including risk management, network security, identity management, security engineering and architecture, or software development security, among others. The exam is theoretical, lengthy and demanding, and in addition to passing the exam, proof of at least five years of professional experience in at least two of the eight domains is required for certification.

The CISSP is designed for experienced professionals who aspire to leadership and management roles. It is an ideal certification for security managers, architects, consultants, and especially for future and current Chief Information Security Officers (CISOs) . Having a CISSP demonstrates a thorough understanding of all aspects of managing a security program in a large organization.

What competencies are demonstrated by the CISM (Certified Information Security Manager) certification?

The CISM (Certified Information Security Manager), offered by the ISACA organization, is another of the “big two” management certifications. As the name suggests, it is 100% focused on information security management from a business perspective.

While CISSP is very broad, CISM is more focused and concentrates on four key areas:

1. Information Security Governance: Defining strategies, policies and management frameworks.
2. Information Risk Management: Identifying, Assessing and Handling Risks.
3. Building and managing an information security program (Information Security Program Development and Management): Building and running a security program.
4. Information Security Incident Management: Overseeing incident response capabilities.

CISM is a purely managerial certification. It is ideal for those whose primary responsibility is to link the security program to the company’s strategy and business goals. It is an excellent choice for CISOs, risk managers, IT directors and auditors who want to confirm their competence in management and not necessarily deep technology.

Why is OSCP (Offensive Security Certified Professional) considered the “gold standard” in penetration testing?

If the CISSP is the gold standard for managers, then the OSCP (Offensive Security Certified Professional) is the undisputed gold standard for offensive security practitioners, or pentesters. Its reputation and prestige stem from one simple fact: it is 100% practical and mercilessly verifies real, not theoretical, skills.

The motto of the organization Offensive Security, which offers the OSCP, is “Try Harder,” which perfectly captures the spirit of this certification. There are no multiple choice questions or memorization tests. The OSCP exam is a 24-hour, hands-on hacking marathon. The candidate is given access to an unfamiliar virtual lab network consisting of several machines with different operating systems and applications. His task is to find vulnerabilities in them on his own, write or modify exploits and take full control (root/administrator privileges) of as many systems as possible.

Passing the OSCP exam proves that a candidate has not only the knowledge, but more importantly the practical skills and specific mindset necessary to conduct a real-world penetration test from start to finish. It’s a certification that commands great respect in the industry and is often a key requirement for recruiting for offensive security positions.
