What this covers.
Operational technology powers manufacturing, energy, water, and transport — and was never designed to be exposed. We assess OT environments with safety-first methodologies, mapping risk against IEC 62443 and the NIST CSF for industrial domains, without disrupting production.
What we test.
Comprehensive coverage across the categories that matter — combined manual and tool-assisted testing.
Network Architecture
IT/OT segmentation, Purdue model adherence, DMZ effectiveness.
Asset Inventory
PLCs, RTUs, HMIs, historians, engineering workstations — discovery and classification.
Protocol Analysis
Modbus, DNP3, OPC-UA, IEC 60870-5-104, EtherNet/IP — exposure and authentication.
Remote Access
Jump servers, VPN, vendor access paths, MFA enforcement.
Endpoint Hardening
Engineering workstations, historians, patch posture, USB controls.
Detection Gaps
Visibility into OT traffic, anomaly detection, incident readiness.
How we run it.
A repeatable, well-documented process so your team always knows what's coming next.
Passive asset discovery and network mapping — no impact to operations.
Segmentation, conduits, and zone trust assumptions against IEC 62443.
Safe, scoped probing of IT/OT boundaries and remote access paths.
Findings rated by safety, availability, and likelihood — not just CVSS.
Prioritized, phased remediation aligned to operational windows.
What you receive.
- Asset inventory and network map
- IEC 62443 / NIST CSF gap analysis
- Risk register with safety-weighted ratings
- Phased remediation roadmap
- Executive briefing for plant leadership
Standards we map to.
Frequently asked.
Will testing impact production?+
No. OT engagements are passive by default. Any active probing happens in controlled windows with operator approval.
Do you work with our OEMs?+
Yes — we coordinate with Siemens, Rockwell, Schneider, Honeywell, ABB, and others as required by warranty and support terms.
