Security+ vs Network+ vs CySA+ vs CEH: Which Certification Is Right for You?

CompTIA Network+ focuses on networking fundamentals: IP addressing, routing, switching, network topologies, cabling, and network troubleshooting. Security+ focuses on cybersecurity: threats, vulnerabilities, cryptography, identity management, risk management, and incident response. Network+ is a prerequisite in knowledge only — you do not need to hold the certification, but understanding networking concepts is essential before studying Security+. Many professionals earn Network+ first, then Security+, then specialize further. If you already have networking experience, you can skip Network+ and go directly to Security+. If you are new to IT, earning Network+ before Security+ builds a stronger foundation. In terms of difficulty, Network+ and Security+ are similar, though Security+ requires learning more conceptual material.

CySA+ (Cybersecurity Analyst) is the next step after Security+ for professionals pursuing a security analyst career path. While Security+ covers foundational security concepts across all domains, CySA+ dives deeper into threat detection, security monitoring, data analysis, and vulnerability management. CySA+ emphasizes practical, hands-on skills like interpreting SIEM alerts, conducting threat hunts, and analyzing log data. Most professionals take Security+ first, gain 1-2 years of experience, then pursue CySA+. The CySA+ exam is harder than Security+ and requires more applied knowledge. Both certifications satisfy DoD Directive 8570 requirements, but at different levels: Security+ fulfills IAT Level II, while CySA+ fulfills CSSP Analyst.

CEH (Certified Ethical Hacker) by EC-Council focuses on offensive security — penetration testing, ethical hacking methodologies, reconnaissance, exploitation, and post-exploitation. Security+ focuses on defensive security — securing networks, managing risk, and responding to incidents. CEH is a more advanced, specialized certification that typically requires 2+ years of security experience. It is significantly more expensive ($1,200+ for the exam voucher) and harder than Security+. If you want to work in penetration testing or red teaming, CEH is valuable. If you are starting your cybersecurity career or pursuing a general security role, Security+ is the better choice. Many professionals earn both: Security+ for the foundation, then CEH when they move into offensive roles.

The recommended CompTIA certification path is: A+ (optional IT foundation) → Network+ (networking foundation) → Security+ (security foundation) → CySA+ (analyst skills) or CASP+ / SecurityX (advanced security). For the DoD 8570 roadmap, the most common sequence is Security+ (IAT Level II) → CySA+ or CASP+ (IAM Level I/II/III). Many professionals deviate from this path based on their career goals. If you are entering cybersecurity without IT experience, start with Network+ then Security+. If you already work in IT, go directly to Security+. From Security+, you can branch into governance (CISSP), offensive security (CEH/OSCP), or analysis (CySA+).
