What is the best first cybersecurity certification?

CompTIA Security+ is the most recommended first cybersecurity certification across the industry. The exam (SY0-701, $404 as of April 2026) covers six domains: general security concepts, threats/vulnerabilities/mitigations, security architecture, security operations, and security program management. According to CompTIA (2024), Security+ is held by more cybersecurity professionals than any other certification.

Security+ satisfies the DoD 8570/8140 IAT Level II requirement, making it a prerequisite for many government and defense contractor cybersecurity positions. This single certification opens access to thousands of job postings that list it as a mandatory qualification. No other entry-level cybersecurity certification has this level of cross-sector recognition.

For absolute beginners who find Security+ too advanced to start with, the Google Cybersecurity Certificate on Coursera ($250, self-paced) provides a gentler introduction. It covers foundational IT concepts, networking basics, Linux, SQL, and introductory security topics. Many learners complete Google's certificate first, then pursue Security+ with stronger fundamentals.

Study timeline for Security+: 2 to 4 months of dedicated study (1 to 2 hours daily). Recommended resources include Professor Messer's free video series, Jason Dion's practice exams on Udemy, and CompTIA's CertMaster Practice platform.
