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
A proof-driven methodology.
Scope & recon
We agree objectives and rules of engagement, then map what you actually expose.
Map the attack surface
Enumerate entry points, roles, and trust boundaries a real attacker would target.
Manual exploitation
Certified testers exploit flaws by hand — chaining issues scanners never connect.
Prove impact
Every finding ships with a working, reproducible proof-of-exploit and business context.
Report & retest
Risk-ranked report with fixes, then a retest that confirms each issue is closed.
Proof you can act on.
Reproducible proof-of-exploit
Every finding ships with a working exploit and evidence.
Risk-ranked report
CVSS + business context, prioritized for your team.
Remediation guidance
Actionable fixes mapped to each finding.
Retest to verified fix
We confirm closure — proof it’s fixed, not assumed.
Make it continuous.
Pair this test with a program that keeps coverage live 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.
