HIPAA-Compliant SIEM: Requirements and How ThreatHawk Meets Them

What §164.312(b) audit controls need from a SIEM — and how ThreatHawk supports HIPAA evidence for covered entities and BAs.

Published: September 2026 Solutions · ThreatHawk · HIPAA 8–12 min read

A HIPAA-aligned SIEM helps covered entities and business associates implement §164.312(b) Audit Controls by collecting, retaining, and examining activity from systems that contain ePHI. ThreatHawk is CyberSilo’s SIEM path for that evidence, paired with CSA for policy and risk artefacts.

§164.312 Technical Safeguards — Standards: Access Control (a), Audit Controls (b) Required, Integrity (c), Person/Entity Authentication (d) Required, Transmission Security (e). Implementation specifications under each standard are Required or Addressable as listed in the regulation.

Documentation retention — 45 CFR 164.316(b)(2): retain Security Rule documentation for 6 years from the date of creation or the date when it last was in effect, whichever is later. This covers policies, procedures, and related documentation — not a separate “6-year SIEM log retention” statute. Operational log retention is a risk-based practice supporting audit controls (164.312(b)).

Boundary

A SIEM does not replace BAAs, risk analysis, or workforce training. Operational log retention is risk-based to support audit controls; the 6-year clock in 164.316(b)(2) applies to Security Rule documentation.

Frequently Asked Questions

What makes a SIEM “HIPAA compliant”?

HIPAA does not certify SIEM products. Fit means you can record and examine ePHI-system activity (§164.312(b)), protect log integrity, and support incident timelines — typically under a BAA if the SIEM vendor is a BA.

Do we need a BAA with our SIEM vendor?

If the vendor creates, receives, maintains, or transmits PHI/ePHI for you, a BAA is generally required.

Is ThreatHawk a replacement for CSA?

No. ThreatHawk supplies monitoring evidence; CSA organises policies, risk analysis, and control status.
