OT360™ Industrial Security Audit
Structured assessment of cybersecurity, operational resilience, connectivity, recoverability, supportability and lifecycle risk across the plant.
Audit the plant. Prove resilience. Train the auditor.
Industrial security you can measure.
OT360™ combines a structured operational technology audit methodology with hands-on auditor training to help manufacturers understand what they have, what could stop production, and how well they can recover.

Two connected offerings
Assess the environment. Build the people who can assess it.
OT360™ creates a repeatable industrial assurance model: a customer-facing audit service and a disciplined training pathway for the auditors who deliver it.

OT360™ Auditor Academy
College-level, hands-on curriculum teaching OT principles, plant walkthroughs, evidence collection, scoring, finding development and executive reporting.
03
OT360™ Continuous
Continuous control validation, evidence refresh, remediation tracking and measurable maturity improvement between formal assessments.
OT360™ Industrial Security Audit
An OT audit designed around production reality.
The methodology is passive-first and evidence-driven. It evaluates whether controls actually reduce operational risk—not whether a policy or checkbox merely exists.
Evidence over assertion
A maturity score of 4 or 5 should be supported by objective evidence and validation, not interview statements alone.
Operational consequence
Findings are translated into production, safety, quality, recovery and business impact—not just technical severity.
Recovery is security
PLC programs, HMI projects, SCADA configurations, industrial PC images, licenses, firmware and spares are evaluated as part of resilience.

OT360™ Auditor Academy
Teach auditors to understand the plant before they grade the plant.
The Academy combines classroom instruction, cyber-range exercises, interviews, evidence challenges, finding-writing drills and a complete simulated manufacturing-site audit.
Weeks 1–3 — Foundations & Audit Safety START HERE
Industrial terminology, PLC/HMI/SCADA concepts, Purdue architecture, zones/conduits, scope, Rules of Engagement, evidence methods, and safe OT audit behavior.
Weeks 4–6 — Risk, Assets & Network Architecture CORE
Plant criticality, asset intelligence, authoritative inventory, passive discovery, communication baselining, segmentation, firewalls, conduits and industrial DMZ concepts.
Weeks 7–9 — Access, Endpoints & Vulnerability CONTROL
Vendor access, MFA, privileged access, engineering workstation security, Fleet/osquery evidence, patch constraints, compensating controls and OT-specific vulnerability prioritization.
Weeks 10–12 — Detection, Recovery & Incident Response RESILIENCE
Wazuh evidence, telemetry, alert context, PLC/HMI backups, restoration readiness, ransomware scenarios and safe containment decision-making.
Weeks 13–15 — Operations, Scoring & Capstone PROVE IT
Physical/supply-chain resilience, lifecycle risk, scoring calibration, report writing, 30/90/365-day roadmap, and the full Atlas Precision Manufacturing simulated OT360™ audit.
Auditor development

Questions
Frequently asked questions
Is OT360™ an IT penetration test?+
No. OT360™ is an industrial security and resilience assessment methodology. Technical validation is passive-first and governed by explicit Rules of Engagement.
Does an auditor need to be a controls engineer?+
No. The Academy teaches enough automation, networking, asset, recovery and process context for competent auditing while respecting where controls-engineering expertise is required.
Why are backup and recovery part of the audit?+
Because cyber resilience depends on the ability to restore PLC programs, HMI projects, industrial PCs, configurations, licenses and supporting infrastructure.
Can OT360™ support multiple sites?+
Yes. The method can be applied at one plant, multiple sites, or as an enterprise program with consolidated reporting.
How is a 4 or 5 maturity score earned?+
Higher maturity requires stronger evidence. A 4 should generally be verified through objective evidence; a 5 should demonstrate consistent measurement, governance and continuous improvement.
Is the credential issued by NIST, CISA or ISA?+
No. OT360™ certification is an independent program credential. Those organizations do not sponsor or endorse OT360™.
