Recurring observation: CISA + CISSP combination is the gold-standard duo for senior GRC / risk / compliance management roles. CISA owns the audit side, CISSP the broader security architecture side. Significant pay premium reported with both.

Total cost-of-ownership notable: $575 (member) / $760 (non-member) exam fee + $135/yr maintenance + 5 years experience requirement (waivers available with degree / other certs). Worth it for audit careers; less so for general security.

Exam Difficulty

Heavy on policy / governance / audit theory rather than technical depth. "ISACA-correct" answers often differ from real-world practice — similar to PMP "PMI-isms". Plan 3–4 months of focused prep even with audit experience.

Industry-standard IT audit cert. Required or strongly preferred for Big 4 (Deloitte, EY, KPMG, PwC) IT audit roles. Median salary uplift in ISACA reports significant. Hemang Doshi YouTube + ISACA's own CISA Review Manual cited most often.
