OT / ICS Security Testing
Safe, scoped testing for operational technology and industrial control environments.
OT/ICS security testing is safe, scoped assessment of operational-technology and industrial-control environments — validating IT/OT segmentation and exposure without disrupting the physical process.
Where attackers get in — and where we look.
Protocol analysis (Modbus, DNP3)
Segmentation (IT/OT) validation
PLC & HMI exposure
Safe-scope methodology
Remote-access review
An evidence-driven methodology.
Scope & safety rules
We agree the in-scope systems, safety constraints, permitted techniques and stop conditions before any testing begins.
Architecture review
We review network zoning, remote access paths and the boundaries between IT and OT environments.
Controlled assessment
Testing favours passive and low-impact techniques; anything that could affect a live process is agreed with your operators first.
Evidence & impact
Findings record what was observed and the plausible operational consequence, without disrupting production.
Report & retest
Risk-ranked reporting with remediation guidance; retests under agreed terms.
Evidence you can act on.
Findings and supporting evidence
QA-reviewed findings with evidence and reproduction steps.
Risk-ranked reporting
CVSS + business context, prioritized for your team.
Remediation guidance
Actionable fixes mapped to each finding.
Retests under agreed terms
Retests are requested and tracked in the platform.
Make it a program.
Pair this test with a program that extends testing between engagements.
OT / ICS Security Testing — questions buyers ask.
Is it safe to test live OT environments?
Safety is the priority. We use a safe-scope methodology, favor passive and lab-based techniques, and coordinate closely to avoid any impact on physical processes.
What protocols do you assess?
Industrial protocols such as Modbus and DNP3, plus PLC/HMI exposure and remote-access paths.
Do you test segmentation between IT and OT?
Yes — validating IT/OT segmentation is one of the most valuable and lowest-risk parts of an OT engagement.
Prove what an attacker could actually do.
A short scoping call, no obligation.
