As cyber-physical systems become more connected, organizations are investing in CPS protection platforms to safeguard against geopolitical, espionage and ransomware attacks. This note guides cybersecurity leaders to learn from ratings and reviews shared by their peers on Gartner Peer Insights.

Voice of the Customer

Gartner Peer Insights Voice of the Customer evaluates vendors in a given technology market by applying a specific methodology to aggregated end-user reviews. Vendors are then positioned into four quadrants based on two criteria: User Interest and Adoption (x-axis), and Overall Experience (y-axis) (see Figure 1). See the Methodology section for details.
Along with the historical peer-based perspective represented in this document, Gartner has a related expert-led Magic Quadrant for CPS Protection Platforms.

All vendors are classified under specific quadrants based on their “overall experience,” and “user interest and adoption.” The Customers’ Choice quadrant in the upper right represents the highest overall experience, and maximum user interest and adoption. Strong Performer is in the upper left. Aspiring is in the lower left. Established is in the lower right. Eligible vendors as of June 2026 — Customers’ Choice vendors: Claroty, Nozomi Networks; Strong Performer vendors: Fortinet; Aspiring vendors: Darktrace, Dragos, ServiceNow (Armis).

Peers’ Willingness to Recommend

Gartner Peer Insights reviewers rate their willingness to recommend each vendor. Figure 2 compares vendors according to the reviewers’ willingness to recommend them.

Market Definition

Gartner defines cyber-physical systems (CPS) protection platforms as products that discover, categorize, map and protect CPS in production or mission-critical environments outside of enterprise IT. They do so by analyzing or interacting with industrial/industry-specific protocols and operational network traffic. They understand physical process asset behavior and do not interfere with CPS operations. They can be delivered from the cloud, on-premises or in a hybrid form. CPS are engineered systems that orchestrate sensing, computation, control, networking and analytics to interact with the physical world (including humans). When secure, they enable safe, real-time, reliable, resilient and adaptable performance.

Methodology

A full description of the methodology can be found on the Gartner Peer Insights Voice of the Customer Methodology page.
Voice of the Customer includes vendors with products aligned to the market that have 20 or more eligible published reviews (and 15 or more ratings for “Capabilities” and “Support/Delivery”) during the 18-month consideration period ending 30 June 2026. Reviews from vendor partners or companies with less than $50 million in revenue are excluded.
In the CPS protection platforms market, Gartner Peer Insights published 688 reviews and ratings during the consideration period.
The data used in this report is drawn from reviews on Peer Insights, a free peer review and ratings platform that regularly publishes new reviews. The Voice of the Customer methodology uses a snapshot of reviews data from a defined time frame and does not automatically update as new reviews are published. The external Peer Insights site will always have the most updated peer view of the vendors and products in this report.
The numerical ratings scores in each vendor summary graphic (shown as “Rating by Category”) are best interpreted as sample statistics with a reasonable margin for error and not as exact values.
