Surviving a Ransomware Audit: What Regulators Actually Look For

The audit starts the moment the incident does

When ransomware hits a regulated firm, the recovery is only half the battle. The other half is the audit that follows — from your cyber-insurer, and often from a regulator (HHS, the SEC, or a state AG). Both ask the same question: did you have the controls you said you had, and can you prove it?

Five things they ask for first

1. MFA coverage evidence across email, VPN, and privileged accounts — not a policy document, a configuration export.

1. Immutable, tested backups. The restore test logs matter more than the backup job itself.

1. EDR/MDR telemetry showing detection and containment timelines.

1. Access reviews — who had standing privileged access, and when it was last reviewed.

1. An incident response plan that was actually exercised, with the tabletop notes to prove it.

Build the evidence library before you need it

The firms that survive these audits cleanly are the ones that maintained a living control-evidence library. That is exactly what we maintain on behalf of our clients — so when the questionnaire arrives, the answers are already documented.
