OT Asset Discovery & Inventory
Gain Complete Visibility Over Your Critical OT Assets
You can only secure the systems you fully understand and can account for. In most industrial environments, there are far more connected devices than anyone realises. Some are added temporarily and never removed from documentation. Others operate quietly on legacy firmware that no one has touched in years.
Blind spots are not just a cybersecurity concern in OT. They can influence how safely and reliably your operations run each day.
Many organisations still rely on static spreadsheets or scattered device records. The longer these go unmaintained, the greater the chance that unmanaged or unknown equipment is sitting on a critical network segment.
Arista Cyber gives you a clear and accurate picture of what is really connected to your OT network controllers, field equipment, and every supporting system. This visibility becomes the baseline for safer operations, stronger compliance, and faster incident response when something goes wrong.
EVERY UNSEEN DEVICE IS AN OPEN DOOR. DISCOVER THEM ALL. SECURE THEM ALL.
Why It Matters for Critical
Infrastructure
In IT networks, an unpatched server can put data at risk.
In OT environments, an unknown PLC or a compromised HMI can put people, production, and safety at risk.
The devices no one is tracking are usually the ones that cause trouble. If you know what is connected to your network, where it lives in the process, and how it behaves, you're far better prepared to avoid slip-ups that interrupt production or put safety under pressure.
Compliance frameworks like IEC 62443 and NERC CIP expect organisations to maintain an accurate, up-to-date inventory of OT assets. Being able to show what exists on your network and how each system is managed makes audit preparation far smoother.
When something does go wrong, time is critical. Knowing exactly which device triggered an alert, along with its role, location, and communication paths, shortens incident response and supports continuity of operations.
What We Deliver
Manual tracking only tells part of the story. We help you replace scattered records with a reliable, verified view of the systems that keep your facility running.
1.Comprehensive Cataloging
Every device that plays a role in your operation gets accounted for, whether it's a PLC tucked in a cabinet, an RTU far out in the field, or an HMI on the plant floor. From DCS equipment to engineering stations and IIoT sensors, nothing remains off the record.
2.Vulnerability Correlation
Your inventory is checked against known weaknesses, so outdated firmware or risky configurations can be addressed before they become real problems.
3.OT Network Mapping
See how devices are communicating across your industrial network, validate segmentation, and spot unusual pathways that deserve closer attention.
4.Lifecycle Management Insight
Some devices quietly age out of support long before anyone notices. We help you spot that early, giving you time to plan upgrades or replacements without putting operations at risk.
How It Works
1.Collaboration & Planning
We work directly with your operations, automation, and network staff to choose the right vantage points in the network. There's no reconfiguration involved; the setup stays as it is. Our role is to learn from your network, not change it.
2.Passive Data Collection
Traffic is captured from SPAN or mirror ports so we can see how systems are communicating without ever touching live controllers. Everything continues to run as usual, with no interference and no risk to operational stability.
3.Automated Classification
Protocols such as Modbus, BACnet, DNP3, and EtherNet/IP are analysed so each device's details, make, model, firmware, and behaviour are captured accurately.
4.Analysis & Reporting
We provide a verified inventory and a risk-focused report that highlights what needs attention first, supported by clear communication flows.
Proven Standards & Expertise
Industrial cybersecurity is built on strong governance. Our methodology fits cleanly into the standards and practices your teams already follow:
- ✔ IEC 62443: Defines secure zones, conduits, and responsibilities for managing industrial assets
- ✔ NIST CSF (ID.AM): Ensures critical equipment is identified, documented, and protected
The outcome is greater confidence in your operations and an easier conversation with regulators when the time comes.
Industries We Support
OT environments differ from one industry to another, but the need for reliable asset visibility remains constant. We support organisations operating in:
- Energy and Utilities
- Oil and Gas, both upstream and downstream operations
- Manufacturing and Automotive
- Pharmaceutical Production
- Transportation and Logistics Systems
Whether it's maintaining power generation, refining operations, assembly lines, or the secure movement of goods, every asset connected to your process must be known and trusted.
Outcomes and Business Benefits
-
✔ Eliminate blind spots
Gain a complete picture of every device authorised or otherwise operating on your OT network. -
✔ Reduce manual effort
Static spreadsheets and scattered notes fall out of date almost as soon as they're saved. A living inventory gives you information you can rely on. -
✔ Strengthen compliance
Clear, exportable inventory data makes audits easier and supports the expectations of industry regulators. -
✔ Prioritise maintenance
Your engineers can focus their time where it matters most, on the systems that present real operational or safety risk.
With a trusted asset inventory, every decision from patching to replacement becomes clearer, faster, and better informed.
Ready to Secure Your Operations?
Protection starts with certainty. If you don't know a device exists, you can't be confident that it's secure. If you are unsure what devices are connected to your OT network today, now is the right time to gain clarity.
We help you build a dependable inventory of the systems that keep your operations moving, one that supports safety today and resilience tomorrow.
