OT Penetration Testing
for data centers, BMS, and plant networks.

Specialized penetration testing for operational technology environments across the Pacific Northwest. We test the systems that keep data centers cool and manufacturers running — Building Management Systems, DCIM, the IT-to-OT boundary, vendor remote access, and the flat networks that let ransomware reach the plant floor — without disrupting production.

Who this is for

Built for the people accountable for uptime.

Data Center Directors & Critical Facility Managers

Hyperscale, colocation, and enterprise data centers across the Pacific Northwest corridor — Hillsboro, Prineville, Boardman, Umatilla, The Dalles, Quincy. We test the BMS, DCIM, leak-detection, fire-panel integration, and the segments your operational technology shares with corporate IT.

VPs of Operations & Plant Managers

Pacific Northwest manufacturers — food & beverage, semiconductor, paper & pulp, metals, aerospace, agriculture & processing. We test plant-floor network architecture, the IT-to-OT boundary, MES & ERP integration, and vendor remote-access pathways.

IT Security Leads owning OT scope

CISOs and security directors who have inherited responsibility for OT and need an independent, framework-aligned assessment for the board, the auditor, or the cyber-insurance underwriter.

What's in scope

The OT attack surface, comprehensively.

Every OT penetration test we run covers the systems and pathways that real adversaries use to move from corporate IT into operational environments. Scope is sized to your facility, but these are the standard areas of evaluation.

Building Management Systems (BMS)

Niagara, Tridium, Honeywell, Johnson Controls Metasys, Siemens Desigo, Schneider EcoStruxure. Supervisor host hardening, controller exposure, integrator access pathways.

DCIM & Facility Telemetry

Power, cooling, environmental sensors. PDU and ATS exposure. UPS monitoring. Whether the DCIM stack shares network with the corporate domain or sits in a true industrial DMZ.

IT-to-OT Boundary

Firewall rule audit. Inter-VLAN routing review. Industrial DMZ design validation. Whether the boundary holds against simulated lateral movement from a compromised IT host.

Vendor Remote Access

Jump hosts, VPN concentrators, vendor-managed always-on tunnels. MFA enforcement. Session recording. Per-vendor credentialing vs. shared-account legacy patterns.

Engineering Workstations

EDR coverage. USB policy. Removable media controls. Local admin scope. Whether engineering laptops are the soft underbelly that bridges corporate phishing to plant-floor ransomware.

Identity & Domain Boundary

AD trust between corporate and plant domains. Service account hygiene. Kerberoasting and DCSync exposure paths into OT-adjacent identity providers.

Historian & Data Diode Egress

PI, Wonderware, IP.21. Whether one-way data flow to corporate is enforced architecturally or merely policy. Backup, replication, and ransomware-survivability of historian data.

Physical & Wireless Edges

Camera systems on the OT network. RFID/badge controllers. Plant-floor Wi-Fi and cellular modem exposure. Loading-dock physical access scenarios.

Detection & Response Pathways

Whether OT segments produce telemetry an MSSP or internal SOC can act on. SIEM coverage of plant networks. The gap between an alert firing and an operator being notified.

Methodology

Five phases. Safety the constant.

Our OT penetration testing methodology is mapped to NIST SP 800-82 Rev. 3, MITRE ATT&CK for ICS, and IEC 62443. Every phase has documented entry criteria, exit criteria, and a written rollback plan.

Phase 01

Week 1

Scoping & Rules of Engagement

Joint workshop with operations, IT, and integrators. Documented zone-and-conduit map. Defined "do not touch" assets. Signed change-window calendar. Emergency stop procedures and escalation tree. Nothing else moves until this is countersigned by your operations lead.

Phase 02

Weeks 1–2

Passive Reconnaissance

SPAN-port traffic capture. Asset discovery via passive listening (no active scanning of OT segments). Configuration review of edge firewalls, switches, and jump hosts. Identity and AD reconnaissance from the corporate side of the boundary only.

Phase 03

Weeks 2–4

IT-side Adversary Emulation

Assumed-breach scenario from a typical phishing landing. Lateral movement, credential harvesting, escalation toward OT-adjacent identity. We measure how close an adversary can get to the OT boundary and whether the segmentation holds. All testing on the corporate network, never crossing into production OT.

Phase 04

Weeks 3–5

Boundary & Vendor-Access Validation

Active testing against the IT-to-OT boundary devices themselves — under change-window control. Vendor remote access pathways exercised end-to-end. Jump host configurations tested for session recording, MFA, and privilege escalation. Active exploitation of any controllers only in a controlled lab against vendor-spare units, never against production.

Phase 05

Weeks 5–6

Reporting & Remediation Working Session

Two-tier report: an executive narrative for leadership and the board, and a technical findings package mapped to NIST 800-82, MITRE ATT&CK for ICS, and IEC 62443 controls. Live working session with your team to walk through every finding, prioritize remediation, and identify owner and target date for each. Free re-test of remediated criticals within 90 days.

Safety-first protocol

We will never crash your production environment.

This is the single non-negotiable that separates legitimate OT penetration testing from IT pentesting applied to industrial environments.

  • 01

    No active scanning of production OT. Passive observation only against live segments. Active probing happens only against test devices in a lab.

  • 02

    No generic exploitation frameworks against OT. Metasploit, NMAP aggressive scans, default Nessus profiles — not used against production OT under any circumstance.

  • 03

    Change windows for everything that touches production. Boundary device testing is scheduled with operations, has a documented rollback, and is tested against backout time before execution.

  • 04

    Operations holds the kill switch. A single phone call from your operations lead halts all testing within 60 seconds. We surface our active testing position daily so your team always knows where we are.

Frequently asked

Common questions about OT pentesting.

What is OT penetration testing?

+

OT penetration testing is adversary-emulation security testing performed against operational technology systems — Building Management Systems, DCIM platforms, plant networks, the IT-to-OT boundary, and vendor remote access pathways. Unlike IT pentesting, OT pentesting requires safety-first methodology, passive reconnaissance against production, and protocol-aware tooling because the assets under test are running real production processes.

How is OT pentesting different from IT pentesting?

+

IT pentesting can use loud, generic exploitation frameworks against systems designed to fail safely under network stress. OT pentesting cannot. A Building Management System will not gracefully reject a malformed packet. A vendor remote-access jump host that crashes can lock out the integrator who needs to respond to an alarm. Our OT testing uses passive reconnaissance, vendor-spare lab devices for any active exploitation, formal change windows, and rollback plans for every test.

Will the test take down our production environment?

+

No. We design every engagement around production continuity. Active exploitation only happens in a controlled lab against representative test devices, never against production controllers. Testing against production segments is passive — observation, traffic analysis, and configuration review. If we identify a vulnerability that requires active validation, we agree on a change window and rollback procedure with your operations team before proceeding.

Do you serve facilities in Oregon and the Pacific Northwest?

+

Yes. We are an Oregon-based OT cybersecurity practice serving the Pacific Northwest hyperscale data center corridor (Hillsboro, Prineville, Boardman, Umatilla, The Dalles, Quincy WA) and Pacific Northwest manufacturers. On-site engagements anywhere in Oregon, Washington, and Idaho are standard scope.

What frameworks does your OT pentesting align to?

+

Our methodology is mapped to NIST SP 800-82 Rev. 3 (Guide to Operational Technology Security), MITRE ATT&CK for ICS, and the IEC 62443 series. Findings are reported with framework-specific control references so they slot directly into your SOC 2, PCI DSS, or audit evidence packages.

How long does an OT penetration test take?

+

A typical OT penetration testing engagement is 3 to 6 weeks of active work, plus a 1 to 2 week reporting and remediation-planning phase. Smaller scopes (a single BMS environment, for example) can be completed in 2 to 3 weeks. Hyperscale data center campuses or multi-site manufacturers typically run 6 to 10 weeks.

Do you also do ICS penetration testing on the controls themselves?

+

Yes — that is our second specialty. ICS penetration testing covers PLCs, SCADA, HMI, historians, and Safety Instrumented Systems with industrial-protocol-aware tooling (Modbus, DNP3, Profinet, OPC-UA). Many engagements combine both specialties — OT pentesting for the network and identity boundary, ICS pentesting for the controls themselves.
