How It Works

From Assessment to Assurance in 4 Steps

Provn transforms complex industrial security assessments into clear, defensible trust intelligence

01

Assess Your Environment

Map your industrial control systems, identify critical assets, and document existing security controls across zones and conduits.

02

Quantify Trust

Our evidence-weighted scoring engine analyzes your security posture against IEC 62443-3-2 requirements, producing a defensible trust score.

03

Trace Requirements

Every score is linked to specific evidence and requirements, creating a complete audit trail from findings to compliance frameworks.

04

Generate Outputs

Automated zone/conduit diagrams, executive reports, and compliance documentation ready for auditors and board presentations.

Platform Capabilities

Trust Intelligence,
Not Just Compliance

Provn transforms manual risk assessments into continuous trust validation—with evidence that holds up in audits, board rooms, and regulatory reviews.

Evidence-Weighted Trust Scoring

Evidence-Weighted Trust Scoring

Move beyond checklist compliance to defensible trust intelligence.

  • Four-pillar evidence taxonomy: Intent, Implementation, Behavior, Validation
  • Time-decay algorithms account for evidence aging and relevance
  • Confidence scoring reflects evidence quality and completeness
  • Board-ready certificates with traceable evidence lineage
Requirements Traceability

Requirements Traceability

Complete visibility from threats to mitigations across your entire OT estate.

  • Threat-to-Risk-to-Capability-to-Requirement mapping
  • Bidirectional traceability ensures no gaps in coverage
  • Framework crosswalks (IEC 62443, ISO 27001, NIST CSF, NERC CIP)
  • Real-time impact analysis when requirements change
Automated Architecture Outputs

Automated Architecture Outputs

Generate zone/conduit diagrams and architecture documentation automatically.

  • Auto-generated network segmentation diagrams
  • IEC 62443 zone/conduit models with security level annotations
  • Asset inventory with criticality scoring
  • Export to Visio, PDF, or PNG for stakeholder reviews

Frequently Asked Questions

Everything You Need to Know

Can't find what you're looking for? Contact our team.

What makes Provn different from traditional compliance tools?
Traditional tools focus on checklist compliance—tick boxes, generate reports. Provn focuses on trust validation through evidence-weighted scoring. We account for evidence quality, age, and confidence levels. This means your trust scores degrade over time without continuous validation, pushing organizations toward continuous improvement rather than point-in-time audits.
How does evidence decay work?
Different evidence types age differently. Intent evidence (policies, procedures) decays slowly. Behavior evidence (logs, monitoring data) decays faster. Validation evidence (penetration tests, audits) has the slowest decay. Our algorithms automatically adjust trust scores as evidence ages, ensuring your trust assessment stays current and defensible.
Can Provn integrate with our existing tools?
Yes. Professional and Enterprise plans include pre-built integrations with ServiceNow (GRC modules), OpenCTI (threat intelligence), and MITRE ATT&CK Navigator. We also provide REST APIs for custom integrations with SIEM, SOAR, asset management, and ticketing systems.
What frameworks does Provn support?
Starter: IEC 62443-3-2. Professional: IEC 62443-3-2, ISO 27001, NIST CSF 2.0. Enterprise: All frameworks including SOC 2, NERC CIP, CIS Controls, and custom framework mappings. We also support crosswalks between frameworks to avoid duplicate assessments.
How long does an initial assessment take?
For a single site with existing documentation: 2-3 days for data gathering, 1-2 days for evidence upload and validation. First trust score and architecture diagram generated within 48 hours. Continuous assessments happen automatically as you update evidence.
Is my data secure?
Yes. We're SOC 2 Type II certified. All data is encrypted at rest (AES-256) and in transit (TLS 1.3). Role-based access control ensures only authorized personnel see sensitive architecture data. Enterprise customers can opt for on-premises deployment or dedicated cloud tenancy.
What outputs does Provn generate?
Trust score certificates (PDF with evidence lineage), zone/conduit architecture diagrams (Visio, PNG, PDF), requirements traceability matrices (Excel, CSV), risk heat maps, gap analysis reports, and executive dashboards. All outputs are timestamped and cryptographically signed for audit trails.
Can we pilot Provn before committing?
Yes. We offer 30-day pilot programs for Professional and Enterprise plans. This includes full platform access for one site, onboarding with a solutions engineer, and a complete trust validation report. Contact our sales team to discuss pilot eligibility and scope.
