What We Do for You
- Discover every connected device without disrupting operations.
- Separate operational technology from the office network.
- Apply protection that respects uptime and safety constraints.
- Monitor for changes in industrial protocols.
- Plan maintenance windows around what actually can be patched.
How this is bought: Bought as an assessment first, then a project priced from what the assessment finds. Build an estimate for your case.
Platforms We Work With
CiscoCheck Point
These are the platforms we work with on client estates. Where a client already owns a different platform, we work with theirs - ARRIX is not tied to any one vendor.
Our Approaches Explained
Passive asset discovery
Finding devices by listening rather than scanning, so nothing is knocked over.
IT/OT segmentation
A controlled boundary between the office network and the plant floor.
Protocol-aware monitoring
Understanding Modbus, DNP3 and similar traffic rather than treating it as noise.
Compensating controls
Protection for systems that genuinely cannot be patched or replaced.
Safety-first change control
Security changes scheduled around operational and safety requirements.
The Standards We Work To
IEC 62443 industrial securityNIST SP 800-82 OT securityPurdue model segmentation
We follow the structure and controls these standards describe. We do not claim to be certified against them - where you need a formal certificate, we prepare the evidence and an accredited body performs the audit.
What You Get
- Connected device inventory
- IT/OT segmentation design
- Monitoring for industrial protocols
- Compensating control plan
- Maintenance and patch schedule

These are the areas clients most often ask us to improve. Your project sets its own targets, measured and agreed with you.
