The CompTIA CySA+ (CS0-003) exam validates the practical skills of a working cybersecurity analyst. It is organised into four domains: Security Operations (33%), Vulnerability Management (30%), Incident Response & Management (20%) and Reporting & Communication (17%). The exam is performance-based and behavioural — you must apply concepts to scenarios, not just recall definitions.

The CySA+ analyst sits inside the security operations centre (SOC), turning raw telemetry into decisions: detect, triage, investigate, and recommend. Unlike Security+, which is broad and foundational, CySA+ is focused on detection and response and assumes you already understand the basics of networking and security controls.

Weight your revision: Security Operations and Vulnerability Management together are about two-thirds of the exam. Master those first, then Incident Response and Reporting.
