OT/ICS Security Assessment

An OT/ICS security assessment evaluates the security posture of your operational technology environment, the industrial control systems, SCADA networks, PLCs, and HMIs that run your manufacturing, processing, or utility operations. These systems were designed for reliability and safety, not security, and they require a fundamentally different testing approach than IT networks.

What Gets Tested

IT/OT network segmentation, industrial protocol exposure, remote access pathways, asset inventory validation, firmware versions, default credentials on industrial devices, historian and HMI security, and the blast radius of a potential compromise crossing from IT into OT. The assessment evaluates your environment against frameworks like NIST SP 800-82 and IEC 62443.

How It Works

OT security assessments are non-destructive by design. There is no active exploitation of production systems. Testing focuses on architecture review, network traffic analysis, configuration auditing, and controlled scanning using OT-safe tools and techniques. All active testing is coordinated with your operations personnel to ensure zero production impact. Assessment can be performed remotely for architecture and configuration review, with on-site work for traffic analysis if required.

What You Receive

A detailed report covering IT/OT segmentation gaps, vulnerable industrial assets, insecure remote access paths, and prioritized remediation recommendations that account for the operational constraints of an OT environment, you cannot just patch a PLC on the same cycle as a Windows server. The executive summary communicates risk in terms of production impact and safety implications.

Who Needs This

Manufacturers, utilities, water treatment facilities, and any organization running industrial control systems. If your business has a production floor, plant, or facility with networked industrial equipment, the boundary between your IT and OT networks is a critical attack surface. This is especially relevant for organizations facing insurance requirements or regulatory pressure around OT security.

How an engagement works

01

Scope

We define what's in bounds, your goals, and any operational constraints. For OT and production systems, safety and uptime come first.

02

Test

Hands-on testing the way a real attacker works. Findings are exploited and verified manually, proof of impact, not just a scanner flag.

03

Report

A prioritized report with clear remediation steps and proof of impact, written to be acted on, not a 200-page scanner dump.

04

Retest

Once your team has remediated, I re-verify the fixes so you can prove the issues are actually closed.

Frequently asked

How long does this take?
Most small-business engagements run one to two weeks from kickoff to final report, depending on scope and the number of targets. You'll get a clear timeline before any testing starts.
Will testing disrupt my operations?
Safety and uptime come first, especially for OT and production systems. We agree on rules of engagement up front, schedule intrusive testing around your operations, and I check in before doing anything risky.
Is the testing automated or manual?
A human drives every engagement and validates each finding by hand. Modern tooling (including AI) helps widen coverage and speed up the tedious parts, but you're paying for verified, exploitable findings, not raw scanner or model output.
Do you offer a retest after we remediate?
Yes. Once your team has fixed the findings, I re-verify the affected issues so you can demonstrate to customers, auditors, or leadership that they're actually closed.
