Information Security Auditor

Most days tend to involve controls testing, evidence review, interviews with IT and security teams, and the documentation that supports findings. You'll often test access controls, change management, vulnerability management, incident response, and data protection programs — producing findings that map to frameworks like NIST CSF, ISO 27001, SOC 2, or PCI DSS. Engagement cadence varies by employer.

The variance between settings is real — internal audit shops at large enterprises have specialized IT and security auditors; Big Four and second-tier audit firms run SOC 2, PCI, ISO certification engagements; consulting firms offer security assessments and program work; regulators audit security at financial institutions and critical infrastructure. Technical credibility with security operations matters — auditors who can talk specifics get further.

People who tend to thrive here are comfortable with deep systems thinking, patient with the documentation requirements of audit work, and capable of bridging audit and security cultures. CISA is the dominant credential, with CISSP, CISM, CRISC also common. The work tends to offer strong demand and broad career paths, with the trade-off being the constant evolution of the underlying technology — for those who enjoy the security-and-audit intersection, the work compounds in value as institutional knowledge grows.
