How to prepare for a compliance audit using your Windows event logs

An audit is coming. Someone needs to prove your systems are logging the right things and retaining the right evidence. Cloud GRC platforms like Vanta and Drata are built for SaaS companies pursuing SOC 2 — they don’t touch your Windows logs. Enterprise SIEMs collect logs but don’t speak compliance. If you’re a hospital, a county sheriff’s office, a school district, or a defense subcontractor, your compliance evidence lives in your Windows event logs. You need a tool that maps it to the controls your auditor is asking about.

The landscape

Arden Comply sits in the middle. It reads your Windows event logs, maps every event to the compliance controls it satisfies, identifies gaps in your audit policy, and generates PDF reports organized by framework and control.

Six frameworks. 73 controls.

Each control maps to specific Windows event categories — 38 in total, covering logon activity, account lifecycle, privilege use, group membership changes, scheduled tasks, and policy modifications. When Arden detects a gap (say, your audit policy isn’t capturing privilege use events), it tells you exactly which Group Policy setting to enable. As soon as events start flowing, the compliance dashboard updates in real time.

Sample HIPAA coverage report from Arden Comply. Each control shows baseline and enriched event category coverage with observed counts.

The report shows coverage for each control, which hosts are contributing data, and what audit policy changes would improve coverage. It changes the audit conversation from “we think we’re logging the right things” to “here’s the evidence, organized by the controls you’re asking about.”

Start with your servers

You don’t need agents on every workstation to satisfy most framework requirements. The compliance-critical events — authentication, account management, privilege escalation, policy changes — are concentrated on your domain controllers, file servers, and systems handling regulated data. Deploy Arden Comply on two or three critical servers and you have continuous compliance evidence for the majority of controls across all six frameworks. A single-person IT shop at a rural clinic can have a compliance report by tomorrow.

Compliance monitoring and threat detection are two views of the same data. The logon events that satisfy HIPAA §164.312(b) are the same events that detect brute force attacks. Arden Complete bundles both into a single platform — detect the attack, then prove you were monitoring for it. Read the SIEM pricing comparison for the full cost breakdown.
