2026 Gartner® Market Guide for CPS Secure Remote Access

Remote access has become a permanent and unavoidable part of cyber-physical systems (CPS) operations. But many industrial organizations still rely on legacy access methods that were not designed for safety-first, industrial environments. The 2026 Gartner® Market Guide for CPS Secure Remote Access delivers a clear message: VPNs, jump servers, and IT-centric access tools create unacceptable risk because they lack asset-level, protocol-aware, and operational controls. To better protect critical systems and processes, “organizations are pivoting from ‘secure connectivity’ to ‘secure operations’ with fit for purpose cyber-physical systems secure remote access products.”
