CDSA Exam Updates (Last Year – Today)
Over the last year, the CDSA (Certified Detection & Security Analyst) exam has remained stable in structure while continuing to reflect real-world detection and defensive security operations. The exam is still a hands-on, scenario-based assessment that focuses on identifying malicious activity, analyzing alerts, and building an accurate understanding of attacker behavior. There have been no major changes to the exam format or overall evaluation approach during this period.
The CDSA content is still highly relevant. Candidates are expected to demonstrate practical skills in threat detection, log correlation, alert triage, and investigation workflows commonly used in SOC and blue team environments. Emphasis remains on understanding attacker techniques, mapping activity to frameworks such as MITRE ATT&CK, and making defensible analytical conclusions based on evidence rather than assumptions.
Candidates should be especially mindful of context and accuracy. Misreading logs, missing correlations between events, or failing to justify conclusions can significantly impact results. Clear note-taking, timeline building, and concise reporting are critical. Time management also matters, as defensive investigations can quickly become detail-heavy if not approached methodically.
Overall, CDSA remains a strong and practical certification for professionals focused on detection engineering, SOC operations, and security analysis roles.
Yes, the CDSA exam is still valid and respected in 2026. It is widely recognized as a hands-on certification for professionals working in detection, blue team, and security analyst roles.
There have been no major structural changes. Recent updates primarily focus on more realistic attack simulations and clearer expectations around investigative reasoning and reporting quality.
