ProofKeel
Provable security, before and after.
ProofKeel Steward keeps self-managed infrastructure hardened, patched, and backed-up — and proves it. ProofKeel Trace detects, investigates, and proves what happened.
Before
Posture you can prove
Hardened, patched, backed-up — attested this week.
After
Events you can prove
Every alert investigated, every artifact chained.
One word runs through both: proof.
The family
Two products, one discipline: proof
Before — posture you can prove
ProofKeel Steward
Keeps self-managed infrastructure hardened, patched, and backed-up — and hands you a current, audit-ready attestation that says so. No security team required.

After — events you can prove
ProofKeel Trace
Detects and investigates every alert, then preserves what happened as court-defensible, chain-of-custody evidence you can verify offline.

Both products ride on one shared account platform: a single organization and login across the family, SAML SSO for teams that need it, and entitlements managed centrally — posture and evidence under one roof.
Why proof
Security claims are cheap. Proof is not.
The shared word across ProofKeel is proof. Before an incident, proof means attestation: a current, signed statement of posture you can hand an auditor or a customer. After one, proof means chain of custody: hash-chained, tamper-evident evidence of exactly what happened — verifiable without taking our word for it.
Attestation
ProofKeel Steward proves posture on a recurring schedule — “as of this week”, not as of a PDF from eight months ago.
Chain of custody
ProofKeel Trace proves events with hash-chained manifests and WORM retention — evidence that holds up long after the incident.
