What it is
Passive monitoring and asset inventory for operational technology such as PLCs, SCADA and building systems, with detection of threats and unsafe changes.
How to value it
Attacks on operational technology stop production lines and can affect safety, and many of these devices cannot be patched for years. Knowing what is on the industrial network and watching it is the first step regulators expect from critical infrastructure under NIS2.
Questions to ask a vendor
- 1Is monitoring fully passive, so it cannot disrupt operations?
- 2Which industrial protocols and equipment vendors does it understand?
- 3Does it show vulnerabilities per device, with mitigations where patching is impossible?
- 4How does it connect to the IT security operations team?

How we list vendors
- A product is listed because it provides the control. Nobody pays to be listed, and on story pages the examples rotate, so no vendor is always first.
- Vendor pages show both the vendor's own research and the incidents involving its products, from our own coverage. We do not leave either out.
- Our summaries are written by us, based on the vendors' own pages. Text in quotation marks or marked "in their own words" is the vendor's own, quoted from its website.
- Logos, product names and quoted text belong to the vendors and are shown to identify them.
- Something wrong? Use "Suggest a correction" on the vendor's page. A product we should look at? Email support@threatnoir.com.
