Tamper-Proof Audit Logs for SaaS
Every event cryptographically chained with SHA-256. One API call to ingest. Instant verification. SOC 2-ready and GDPR-compliant out of the box.
$ curl -X POST https://logproof.de/v1/events \
-H "Authorization: Bearer lp_sk_..." \
-H "Content-Type: application/json" \
-d '{"action":"user.login","actor":{"id":"usr_123"}}'Cryptographic Hash Chain
Every event is cryptographically linked to the previous one. Tampering with any record breaks the chain.
Everything You Need for Audit Logging
From ingestion to compliance exports — Logproof handles the full audit trail lifecycle.
Hash-Chain Integrity
Every event is SHA-256 hashed and chained to its predecessor. Any tampering is instantly detectable through cryptographic verification.
Real-Time Ingestion
Sub-100ms ingestion via REST API. Send single events or batch up to 1,000 at once. Built for high-throughput SaaS workloads.
Smart Alerting
Set up pattern matching and threshold-based alerts. Get notified via email, webhook, or Slack when suspicious activity occurs.
Export & Compliance
Export logs as JSON or CSV anytime. Configure retention policies to meet SOC 2, GDPR, and HIPAA requirements automatically.
Embeddable Widget
Drop a customer-facing activity timeline into your app. White-label ready with full CSS customization support.
Team & Permissions
Invite team members with granular roles. Control who can view, export, or manage audit logs across your workspaces.
One API Call. That's It.
Send an event, get back a cryptographic receipt. No SDKs required — just HTTPS.
