CompTIA Security+ and CISSP are both cybersecurity certifications, and both appear regularly on security-focused resumes. But treating them as equivalent is a significant mistake. They sit at completely different points on the experience spectrum and signal very different things about a candidate.
CompTIA Security+ — The Entry Point
Security+ is an entry-level cybersecurity certification that covers foundational concepts: network security, threat management, cryptography, access control, and basic risk management. It's vendor-neutral, widely recognized, and often required by the Department of Defense for certain contractor roles.
What it signals is foundational competency and commitment to the field — not deep expertise. A candidate with Security+ has demonstrated they understand the basics of cybersecurity and cared enough to formalize that knowledge. For junior security analyst roles, IT support positions with a security component, or help desk roles in regulated industries, Security+ is a meaningful and appropriate credential.
What it doesn't signal is hands-on experience with real security operations, incident response, or security architecture. You can earn Security+ with study and limited practical experience. Treat it as a starting point, not a destination.
CISSP — The Senior Standard
The Certified Information Systems Security Professional is a completely different animal. To even sit the CISSP exam, candidates need a minimum of five years of paid work experience in at least two of eight cybersecurity domains. There are no shortcuts — ISC2 verifies the experience requirement before granting the certification.
The exam itself covers security architecture, engineering, risk management, software development security, and more at a depth that requires genuine mastery. Passing it typically requires months of dedicated study even for experienced professionals.
A CISSP on a resume is one of the strongest signals in cybersecurity hiring. It tells you the candidate has substantive, verified experience in the field, has demonstrated broad and deep knowledge across the discipline, and has committed to ongoing professional development — CISSP requires 120 continuing education credits every three years.
How to Use This in Hiring Decisions
For junior and mid-level security roles: Security+ is appropriate and meaningful. CISSP would be unusual and may signal the candidate is overqualified.
For senior security analyst, security engineer, or security architect roles: CISSP is a strong positive signal. Security+ alone on a senior candidate's resume warrants a closer look at their actual experience — the credential undersells what the role requires.
For CISO or security leadership roles: CISSP is essentially a baseline expectation. Its absence from a senior security leadership candidate is worth questioning directly.
Verifying Both
CompTIA certifications can be verified at verify.comptia.org. CISSP credentials can be verified at isc2.org/MemberVerification. Both take under a minute and confirm whether the certification is current and active.
