AuditRails gives your application a permanent, tamper-evident record of everything that matters. Every event you log is cryptographically chained to the one before it using SHA-256, stored in WORM-compliant S3 Object Lock storage, and indexed for sub-second querying — so you always know exactly what happened, when, and who did it, with proof that the record has never been altered.

​
Key Features

Immutable Hash Chains

Every event is SHA-256 chained to the previous one. Any tampering instantly breaks the chain and is detected automatically.

WORM Storage

Logs are written to S3 Object Lock in COMPLIANCE mode — once written, they cannot be deleted or modified by anyone, including AuditRails staff.

16+ Compliance Frameworks

Out-of-the-box audit trails for SOC 2, HIPAA, ISO 27001, GDPR, PCI DSS, and 13 more frameworks — ready for your next audit.

Drop-In SDKs

Official SDKs for Node.js, PHP, Python, Go, and Java. Add tamper-proof logging to any application in minutes with a single API call.

​
How It Works

Every event you send passes through a four-stage pipeline that guarantees integrity and durability:
Events are hashed on ingest, appended to your tenant’s hash chain, and fanned out to both hot storage for real-time querying and cold storage for long-term, tamper-proof retention. No event is ever overwritten or deleted from the chain.
