What Is CompTIA Security+? Complete Guide 2026

CompTIA Security+ is the world's most widely adopted entry-level cybersecurity certification. Over 700,000 professionals have earned it — and for good reason. It is vendor-neutral, DoD-approved, and recognized by employers from Microsoft to the US Department of Defense.

If you are considering a career in IT security, Security+ is the logical first step.

What Does CompTIA Security+ Cover?

The current exam (SY0-701) covers six core domains:

• General Security Concepts (12%) — cryptography, authentication, core security principles
• Threats, Vulnerabilities and Mitigations (22%) — attack types, malware, vulnerability management
• Security Architecture (18%) — network infrastructure, cloud security, virtualization
• Security Operations (28%) — incident response, digital forensics, identity management
• Security Program Management and Oversight (20%) — risk management, compliance, data privacy

Who Is CompTIA Security+ For?

Security+ is designed for:

• IT professionals moving into cybersecurity (1-2 years experience recommended)
• Help desk and systems administrators looking to specialize
• Career changers targeting cybersecurity roles
• Anyone pursuing DoD 8570/8140 compliance

You do not need to be a security expert to start. The exam assumes foundational IT knowledge, but many candidates pass without prior certifications.

3. Salary increase. Certified professionals earn 20-30% more than non-certified peers in equivalent roles, according to CompTIA research.

How Long Does It Take to Prepare?

Most candidates study for 6-12 weeks:

• With IT experience: 6-8 weeks (2-3 hours/day)
• Career changers: 8-12 weeks (consistent daily study)
