About This Exam

CS0-003 is the exam for the CompTIA CySA+ (Cybersecurity Analyst+) certification. It validates the ability to run security operations: analyzing system and network architecture, logs and indicators of potentially malicious activity, using tools and techniques to investigate threats, applying threat intelligence and threat hunting, and improving efficiency through process standardization and automation; to manage vulnerabilities by scanning and assessing results, prioritizing findings by risk and context, and recommending and applying mitigations and controls; to manage incident response with attack frameworks such as MITRE ATT&CK and the Cyber Kill Chain, through detection, analysis, containment, eradication, recovery and post-incident activities; and to report and communicate vulnerability and incident findings, metrics and recommendations to stakeholders. It is for security analysts, SOC analysts, incident responders, threat hunters and other IT professionals who detect, analyze and respond to threats. CompTIA has announced that the English version of CS0-003 retires on December 22, 2026, after its successor CySA+ V4 launched in June 2026.
