Comptia vs. CISSP: What are the Prerequisites?

CompTIA Certifications

To take the CompTIA Security+ certification exam, there are no formal prerequisites. However, CompTIA recommends that candidates have at least two years of experience in IT administration with a focus on security before attempting the exam. Additionally, it’s recommended that candidates have earned the CompTIA Network+ certification, which covers the basics of networking.

CISSP Certification

To be eligible for the CISSP certification, candidates must have at least five years of experience in two or more of the eight domains covered by the exam. The domains are Security and Risk Management, Asset Security, Security Architecture and Engineering, Communication and Network Security, Identity and Access Management (IAM), Security Assessment and Testing, Security Operations, and Software Development Security. Candidates who don’t meet the experience requirement can still take the exam and earn the Associate of (ISC)² designation. They then have up to six years to gain the required experience to earn the full certification.

Which Certification Should You Pursue?

The answer to this question depends on your career goals and experience level. If you’re just starting out in cybersecurity and don’t have any formal experience, the CompTIA Security+ certification is an excellent place to start. It will give you a solid foundation in cybersecurity concepts and may make you eligible for entry-level cybersecurity positions.

If you have some experience in IT administration, and want to take your career to the next level, the CISSP certification is the better fit. It’s designed for experienced professionals and covers a broad range of topics that are essential for cybersecurity leaders. Earning the CISSP certification can open up numerous high-paying career opportunities in the industry.


Both the CompTIA Security+ and CISSP certifications are highly regarded in the cybersecurity industry, but they serve different purposes. The CompTIA Security+ certification is an excellent starting point for those just beginning their cybersecurity careers. The CISSP certification, however, is designed for experienced professionals looking to take their careers to the next level. Regardless of which certification you pursue, it’s essential to have a solid foundation in cybersecurity concepts and to keep your skills up to date in this ever-evolving field.
