Key Differences Between CS0-003 and CS0-004 Exams

The CompTIA Cybersecurity Analyst (CySA+) CS0-004 exam introduces updated objectives designed to reflect the evolving responsibilities of modern cybersecurity analysts.

While CS0-003 established core skills in security monitoring, vulnerability management, incident response, and reporting, CS0-004 expands these areas with stronger alignment to modern enterprise security operations, including cloud environments, automation, threat intelligence, and AI-related security practices.

What are the major changes in CySA+ V4?

The CySA+ V4 (CS0-004) exam updates the certification objectives to better match modern cybersecurity operations.

The major changes include:

● Expanded Security Operations Coverage: Greater focus on analyzing malicious activity across networks, endpoints, cloud platforms, and identity systems.

● Updated Security Tool Knowledge: Increased emphasis on SIEM, EDR, packet analysis tools, and threat intelligence platforms.

● Enhanced Threat Intelligence and Threat Hunting: Stronger focus on attack frameworks, threat investigation methods, and identifying advanced security threats.

● Risk-Based Vulnerability Management: More emphasis on vulnerability prioritization using scoring systems, threat intelligence, and business context.

● AI in Security Operations: Introduction of AI use cases, security risks, and governance considerations.

● Security Automation and Process Improvement: Greater attention to automation workflows and improving SOC efficiency.

● Improved Reporting and Communication Skills: Increased focus on dashboards, security metrics, incident documentation, and communicating risks to stakeholders.

Overall, CySA+ V4 moves beyond traditional security monitoring and places more emphasis on modern security operations, automation, and intelligent threat analysis.

Should I take CS0-003 or CS0-004?

The decision between CySA+ CS0-003 and CS0-004 depends on your current preparation status.

You may choose CS0-003 if:

● You have already completed significant preparation based on the CS0-003 objectives

● Your study materials and practice resources are aligned with the previous exam version

● You plan to complete the exam before December 22, 2026

You should consider CS0-004 if:

● You are starting your CySA+ preparation now

● You want the latest version of the certificatio

● You want cybersecurity skills aligned with current SOC analyst responsibilities
