Where Logs Become Evidence.
You already log everything.
But can you prove none of it was touched?
Self-hosted audit logging with SHA-256 hash chaining — any modification or deletion of logs is instantly detectable.

01. Why TamperTrail?How TamperTrail Solves This
The Problem With Standard Logs
Standard application logs are not evidence.
- Your data leaves your servers — Cloud logging tools store your logs on their infrastructure. Sensitive data, patient records, payment info — all of it sits on a vendor you don't control.
- No proof logs weren't touched — Any database with
UPDATEaccess can be silently edited. No standard logger detects this. Auditors can't verify what they can't prove. - Anyone with DB access can delete records — Quietly. No trace. No alert. An insider covers their tracks and your audit trail shows nothing happened.
Teams discover this gap too late — when an auditor asks for tamper-proof evidence during SOC 2, or when investigating an insider breach.

Why SaaS lock-ins and plain PostgreSQL tables are a liability for raw audit trails.
