TL;DR: 13 vendors are evaluated across four CPS use cases in Gartner's 2026 Critical Capabilities report, according to Armis. Prioritisation now has to connect exposure to operational context, or remediation stays split from the work that reduces risk.
Editorial analysis by NHI Mgmt Group, based on content published by Armis: “Armis Recognized in the 2026 Gartner® Critical Capabilities for CPS Protection Platforms”.
Key questions
A: Raw counts ignore whether a device is safety-critical, business-critical, or isolated from meaningful attack paths.
Q: How do security teams know whether CPS remediation is actually working?
A: They should look for shorter time-to-triage, fewer repeated exposures, and clearer ownership across security and operations.
Q: What breaks when CPS security platforms only provide visibility without prioritisation?
A: Visibility alone breaks down because operations teams still cannot tell which exposures threaten continuity, safety, or production first.
Practitioner guidance
- Define CPS prioritisation criteria by business impact Set explicit rules for ranking exposures using asset criticality, operational dependency, and exposure pathway so remediation decisions are consistent across plants, sites, and business units.
- Validate passive discovery coverage in live environments Test whether discovery methods can identify assets and context without disrupting fragile systems, and confirm they produce enough detail for remediation planning.
- Integrate CPS findings into remediation workflows Connect exposure data to ticketing, case management, and change processes so owners can track remediation through to closure.
Bottom line: CPS security programmes fail when discovery, prioritisation, and remediation sit in separate operational loops.

CPS security is becoming a governance problem before it is a tooling problem. The article’s real signal is that teams are being asked to prove they can align asset discovery, vulnerability context, and remediation priority to operational requirements. In cyber-physical environments, a long device list is not enough if it cannot drive safe action. Practitioners should treat CPS governance as exposure management with operational guardrails, not as a separate visibility project.
A question worth separating out:
Q: What is the difference between CPS asset discovery and CPS exposure prioritisation?
A: Asset discovery answers what exists and where it sits in the environment. Exposure prioritisation answers which of those assets matter most right now, based on operational criticality, attack pathways, and business impact, so teams can act in the right order.
