About Provn
Provn transforms industrial risk assessments from point-in-time checklists into continuous, evidence-backed trust intelligence. We built the platform we wished existed when conducting IEC 62443-3-2 assessments across energy, manufacturing, and utility sectors.
Our Mission
Make operational trust measurable, defensible, and actionable for critical infrastructure operators.
Traditional GRC tools treat compliance as a binary state: compliant or non-compliant. But trust isn't binary—it degrades over time, varies by evidence quality, and requires continuous validation. Provn brings evidence decay, confidence modeling, and automated traceability to industrial risk management.
Why We Built Provn
After conducting dozens of IEC 62443 risk assessments for OT environments, we identified three critical gaps:
Evidence Ages
A penetration test from 2 years ago doesn't provide the same trust as one from last month. Yet most tools treat all evidence as timeless.
Traceability Gaps
Proving threat-to-risk-to-control-to-requirement linkage is manual, error-prone, and impossible to maintain at scale across multiple sites.
No Board-Ready Metrics
Executives need trust scores, not 200-page reports. Compliance status should be a single, defensible number backed by evidence lineage.
Our Approach: Evidence-Weighted Trust
Provn's trust scoring model is built on four pillars of evidence:
Policies, procedures, and documented controls (slow decay)
Configuration snapshots, deployment records (medium decay)
Logs, monitoring data, SIEM events (fast decay)
Audits, penetration tests, third-party assessments (very slow decay)
Why This Matters for Critical Infrastructure
When a water treatment plant, energy substation, or manufacturing facility is compromised, the consequences aren't just financial—they're physical. Lives, environments, and communities depend on these systems.
Provn ensures that the trust score you present to regulators, auditors, or your board is backed by time-stamped, traceable evidence. If your trust score is 87%, we can show you exactly which evidence artifacts contributed to that score, when they were last validated, and what would improve it.
