SIEMs are excellent at ingesting, correlating, and searching security events at scale. But the events they hold are still records the operator controls. ProofLink adds what a SIEM doesn't: cryptographic, independently verifiable proof that a specific action happened and wasn't altered.
The honest verdict
This isn't a rip-and-replace. Keep your SIEM as the detection, correlation, and retention layer. Use ProofLink receipts as the tamper-evident evidence layer for autonomous and AI-driven actions — so the story your SIEM tells about a remediation is backed by proof an auditor can verify independently.
| Capability | iTechSmart | SIEM evidence |
|---|---|---|
| Event ingestion & correlation | Not the job — consumes signals, closes the loop | Core strength; the reason SIEMs exist |
| Long-term retention & search | Evidence chain, not a search index | Mature retention and hunting tooling |
| Tamper-evident action records | SHA-256 + Ed25519 + Bitcoin anchor per action | Stored events the operator can alter |
| Independent verification | Public verifier, no account required | Trust the operator's platform |
| Proof a remediation actually worked | Verified outcome sealed into the receipt | Records that a rule fired, not that a fix held |
| Governance of the action itself | Arbiter gates the action before it runs | Detects and alerts; humans act |
We'd rather you pick correctly than pick us. These are the real cases where we'd point you elsewhere.
Your primary need is security event collection, correlation, threat hunting, and long-horizon retention — that's the SIEM's home turf.
You already have a SIEM investment and want to add proof, not replace detection.
No. It complements it. Your SIEM stays the detection and retention layer; ProofLink adds tamper-evident, independently verifiable proof for the autonomous and AI-driven actions taken in response.
