Dispel

Dispel provides secure remote access, data streaming, and threat monitoring for industrial control systems (ICS) and operational technology (OT). Its Zero Trust Engine platform is built on Moving Target Defense (MTD) principles combined with a composable SD-WAN architecture, aiming to give plant operators and utilities standardized, auditable access across legacy equipment, modern IIoT devices, and distributed OT environments without the access sprawl that ad-hoc VPNs create.

Founded in 2015, Dispel has focused specifically on the OT secure remote access niche rather than general enterprise remote access, positioning it against IT-first competitors that bolt OT support onto existing products. Distinct features include disposable jump systems designed to limit ransomware and malware persistence, session recording for audit, and access-control-list enforcement tied to identity. The company reports connecting users to OT systems in under 30 seconds and was named the Fastest Growing Cybersecurity Company in the 2025 Cybersecurity Excellence Awards.

Dispel is trusted across manufacturing, energy, and utilities customers, though as a privately held company it does not disclose funding or detailed customer counts. Its differentiation is OT-native design rather than breadth, which is a real strength for critical-infrastructure buyers but limits its addressable market relative to general-purpose zero-trust access vendors.
