An audit log your auditor can actually use.
SOX, MiFID II, and SEC Rule 17a-4 all demand the same thing: immutable, reproducible, time-stamped records. CortexDB stores data that way by design.
Most stacks bolt audit logging on top of mutable storage. The result is a log you have to trust — not one you can prove.
Capabilities that map directly to the pain.
WORM by construction
Event-sourced storage. Records are appended, never rewritten.
Reproducible queries
Recall the exact state the system returned at any past point — no "what did we show the trader at 2:14pm?" mystery.
7+ year retention
Tiered storage with retention policies expressed in config, not cron jobs.
Field-level access control
Namespace isolation extends to per-field scopes for PII and MNPI.
The architectural decisions that matter here.
Audit-ready exports
One command produces a sealed, hashed extract for examiners.
No LLM rewrites
Raw evidence stays raw. Enrichment is additive, not destructive.
Want to see this running on your data?
PHI handling that survives a BAA review.
Patient data needs encryption, scoped access, and an audit trail granular enough to answer "who saw what, when?"
Air-gap friendly. Telemetry-free.
FedRAMP, IL5, and classified environments don't tolerate phone-home telemetry or unsigned dependencies. CortexDB ships without either.
Data that stays where the law says it stays.
GDPR doesn't care about your replication topology. Personal data leaves the region only when you say it does.
