Tamper-Proof Audit Logs.
Independently Verifiable.

Blocklog Security cryptographically proves that security logs have not been altered — using deterministic hashing and public blockchain timestamps. Built for audit, compliance, and forensic readiness.

The Problem

Security logs are critical audit evidence — but today they are internally stored and implicitly trusted.

How do we know these logs weren’t modified?
When exactly was this data finalized?
What independent proof exists?

Most logging systems cannot answer these questions convincingly.

What Blocklog Does

Blocklog Security adds an independent integrity layer on top of your existing logging stack.

We do not replace your logs. We make them cryptographically verifiable.

How It Works

Your system sends logs as usual (no disruption)
Logs are batched deterministically and hashed
The batch hash is anchored on a public blockchain
An immutable timestamped proof is created
Auditors independently verify integrity at any time

No trust in Blocklog is required to verify the evidence.

Why Auditors Trust This

Independent timestamps (public blockchain)
Tamper-evident by design
Deterministic replay & verification
Read-only, non-intrusive integration
No reliance on vendor-controlled storage

Pilot Program

We are running a limited pilot program for early-stage teams preparing for audits.
