CompTIA Cybersecurity Analyst Certification Training Course
CompTIA CySA+ Certification Training Course
Build the detection, analysis, vulnerability management, incident response, and reporting skills analysts use every day. Accumentum’s CompTIA CySA+ course now prepares you for CySA+ V4 (CS0-004), released June 23, 2026.
Course focus: Security operations, AI in security operations, threat intelligence and hunting, vulnerability management, incident response and management, and reporting and communication, aligned with CompTIA’s CySA+ V4 (CS0-004) exam objectives.
Course Overview
Develop the practical cyber defense skills required for security operations, vulnerability management, incident response, and analyst-level communication.
Accumentum’s CompTIA CySA+ Certification Training Course is for current and aspiring SOC analysts, incident response analysts, vulnerability management analysts, threat intelligence analysts, and IT security staff who need to detect, analyze, prioritize, respond to, and report on threats.
The course now follows CySA+ V4, exam code CS0-004, which CompTIA released on June 23, 2026. The four domains are Security Operations (34%), Vulnerability Management (26%), Incident Response and Management (24%), and Reporting and Communication (16%). V4 adds an objective on the use of AI in security operations and names SIEM, EDR, packet analysis, and threat intelligence platforms as core analyst tools.
CySA+ V3 (CS0-003) is retiring. CompTIA retires the English CS0-003 exam on December 22, 2026, and the Japanese, Portuguese, and Spanish versions on March 23, 2027. If you are partway through CS0-003 study, the transition section and FAQs below explain your options.
Instruction connects each objective to analyst work: reading logs and telemetry, correlating alerts, hunting for threats, running and interpreting vulnerability scans, prioritizing remediation, supporting incident response, and writing reports that non-technical stakeholders can act on.
Course Objectives
Build CySA+ CS0-004 readiness and operational cybersecurity analyst capability.
01
Security Operations
Analyze indicators of malicious activity across networks, endpoints, cloud, and identity systems, use SIEM and EDR tools, apply threat intelligence and hunting, and explain how AI is used in security operations.
02
Vulnerability Management
Choose the right scanning method, analyze tool output, prioritize vulnerabilities with risk-based approaches, and explain control types and compliance practices used to manage risk.
03
Incident Response and Management
Apply attack methodology frameworks such as MITRE ATT&CK and the Cyber Kill Chain, follow the incident response process, and use triage, evidence handling, escalation, and root cause techniques.

CySA+ CS0-004 Exam Readiness
Accumentum’s CySA+ course prepares you to analyze malicious activity, manage vulnerabilities, support incident response, and report findings across all four CS0-004 domains.
CompTIA released CySA+ V4, exam code CS0-004, on June 23, 2026. CS0-004 has a maximum of 85 questions, a 165 minute time limit, and a passing score of 750 on a scale of 100 to 900. It is offered in English, with French, Japanese, Spanish, and Portuguese listed by CompTIA as coming soon. CompTIA recommends about four years of experience in a SOC analyst or vulnerability analyst role.
CySA+ V3 (CS0-003) is retiring. CompTIA retires English CS0-003 learning products on November 22, 2026, the English CS0-003 exam on December 22, 2026, and the Japanese, Portuguese, and Spanish versions on March 23, 2027.
The four domain names stay the same, but the weights change. Security Operations moves from 33% to 34%, Vulnerability Management from 30% to 26%, Incident Response and Management from 20% to 24%, and Reporting and Communication from 17% to 16%. CS0-004 adds an objective on the use of AI in security operations.
If you are ready to test on CS0-003, schedule before December 22, 2026 (English). If your test date will be later, study for CS0-004.
Accumentum is an independent training provider. CompTIA sets and changes exam rules, dates, fees, and policies, so confirm current details on comptia.org before you schedule.
