What does CS0-003 mean?

CS0-003 is the current exam code for CompTIA CySA+ (Cybersecurity Analyst+), version 3. "CS0" denotes the CySA+ series and "003" the V3 revision. It validates security-analyst skills in threat detection, monitoring, and incident response.

What it means

CySA+ stands for Cybersecurity Analyst+; CS0-003 is its current (V3) exam. CompTIA's official page frames it as an intermediate, defensive-security credential focused on behavioral threat detection, security monitoring, and response — generally pursued after foundational security knowledge rather than as a first credential.
