Meet Compliance Requirements with Tamper-Proof Audit Trails
Logsync helps you meet audit logging requirements for SOC 2, HIPAA, GDPR, NIS2, PCI-DSS, ISO 27001, and more. Cryptographic integrity verification gives auditors confidence your logs haven't been altered.
Built for Compliance from Day One
Every feature is designed to help you pass audits and prove compliance.
Cryptographic Hash Chain
Every event is cryptographically linked to the previous using SHA-256. If any log is modified, the chain breaks - providing mathematical proof of tampering.
One-Click Integrity Verification
Auditors can verify your entire audit trail with a single click. No technical expertise required - just clear pass/fail results.
Configurable Retention
Keep logs for 30 days to 3 years depending on your compliance requirements. Data is securely stored and always available.
Compliance-Ready Exports
Export your audit logs as JSON or CSV for compliance audits, incident investigations, or authority reporting.
Complete Actor Tracking
Every event captures who (actor), what (action), and which (resource) with timestamps and optional metadata.
Server-Side Timestamps
Timestamps are generated server-side, not by clients. This prevents timestamp manipulation and ensures accurate sequencing.
Cryptographic Hash Chain
Unlike traditional logging where logs can be silently modified, Logsync creates an unbreakable chain. Each event's hash includes the previous event's hash, creating a chain that breaks if anything is altered.
What Auditors See When They Verify Your Logs
Give your auditors confidence with clear, verifiable proof of log integrity.

Verification API Response
Programmatic verification for compliance tools
// POST /api/events/verify
{
"success": true,
"valid": true,
"verified": 2847,
"chainIntact": true,
"issues": [],
"range": {
"start": {
"id": "1",
"hash": "a3f2b1c8..."
},
"end": {
"id": "2847",
"hash": "2d8f1a9e..."
}
},
"summary": "Successfully verified 2847 events. Hash chain is intact."
}For auditors: This response proves mathematically that no logs have been modified since creation. Each event's hash incorporates the previous event, creating an unbreakable chain.

}When Tampering is Detected
Clear alerts if logs have been modified
Hash Chain Broken
One or more events have broken chain links.
Issues Found
For auditors: This proves someone attempted to modify log #1,234 after it was recorded. The hash chain provides forensic evidence of tampering.
