OT Security
In operational technology, availability and safety come first. We assess OT and ICS environments with passive, non-disruptive methods, and focus on the separation between your IT and plant networks.
Why teams choose Adiroha
- Manual-first testing, not scanner dumps
- OSCP, OSWE and CEH certified testers
- Findings mapped to ISO 27001, SOC 2 and PCI DSS controls
- Retest and closure letter to prove fixes
Scope
What we cover
- Asset inventory and network architecture review
- IT/OT segmentation and Purdue-model zoning
- Remote access and vendor connectivity
- PLC, HMI and SCADA configuration review
- Passive traffic analysis of industrial protocols
- Gap assessment against IEC 62443
Deliverables
What you receive
- OT risk register prioritised by safety and operational impact
- Zone and conduit recommendations
- Remediation roadmap sized to maintenance windows
- Executive briefing for plant and IT leadership
How we work
Discover. Assess. Remediate. Validate.
Discover
Agree scope, assets, test windows and rules of engagement. Every project gets a unique audit code for tracking.
Assess
Manual-first testing aligned to recognised standards, with critical issues flagged to you immediately.
Remediate
Findings ranked by business impact, with clear fix guidance and a walkthrough with your engineers.
Validate
We retest your fixes, update the report and issue a closure letter you can share.
FAQ
Common questions
Will you touch live control systems?
Not without explicit agreement. We default to passive, observation-based methods and coordinate any active checks with plant engineering.
Which standards do you follow?
IEC 62443 is our primary reference, supported by NIST SP 800-82 guidance for OT security.
Can you assess OT without stopping production?
Yes. Our default approach is passive and observation-based, designed to run during normal operations without affecting availability.
Do you work with plant engineers?
Always. OT assessments are planned with plant engineering and operations so that safety and uptime come first.
Which industries do you cover?
Manufacturing, energy, utilities, pharmaceuticals and other environments that run industrial control systems.
