Dispel Zero Trust Engine
Secure remote access for OT and industrial control systems with sub-30-second connections.
Vendor Information
Dispel Zero Trust Engine Overview
Dispel Zero Trust Engine is a secure remote access and connectivity platform for operational technology (OT), industrial control systems (ICS), and cyber-physical systems from Dispel, founded in 2014 by Ethan Schmertzler (Co-CEO) and Ian Schmertzler (President) and headquartered in Austin, Texas with offices in New York, Washington DC, and Tokyo. The company has raised $28M in total funding, pioneered network-level Moving Target Defense (MTD) technology with 43+ patents, and was recognized as 2024 Cyber Defense Magazine Hot Company in Zero Trust Platform category and 2017 Gartner Cool Vendor.
The platform provides three core capabilities across a unified solution: OT Secure Remote Access enables sub-30-second connections to mission-critical assets (vs. traditional 7-12 minute connection times), replacing complex jump servers and VPNs; OT Data Streaming enables secure, encrypted real-time data transfer between industrial assets and cloud analytics for predictive maintenance and AI; and OT Threat Monitoring delivers 24/7 SOC protection with anomaly detection, session recording, and SIEM/SOAR integration. The proprietary Moving Target Defense technology continuously mutates attack surfaces by dynamically changing network configurations, IP addresses, and infrastructure in real-time, creating ephemeral, compostable infrastructure that prevents persistent footholds. The platform supports all 65,000+ TCP/IP protocols including SSH, RDP, VNC, and proprietary OT protocols (Modbus, DNP3, BACnet, OPC-UA), with OTFusion capability unifying fragmented OT DMZ architectures to reduce operational complexity by 30%.
The solution has achieved SOC 2 Type II and ISO 27001 certification, supports compliance with IEC 62443, NIST 800-53 High Baseline, NIST 800-82, NERC CIP, CMMC, NIS2, and FIPS 199 Impact Level High, and has established strategic partnerships with Mitsubishi Electric Automation, ABB, ICONICS, and Nozomi Networks. The platform protects $500 billion in manufactured goods annually, secures 54 million utility users worldwide, protects 50% of baby formula manufactured in the US, and secures 1 in 5 non-alcoholic beverages produced in America, serving critical infrastructure including electric utilities, water/wastewater, oil & gas, manufacturing, defense, and federal agencies.
Key Capabilities
Standardized capabilities mapped to this product's security niche
Manages third-party vendor remote access sessions with just-in-time provisioning, time-limited credentials, and session approval workflows, replacing always-on VPN access to OT networks.
Analyzes OT protocol commands within remote sessions, alerting on commands outside the authorized scope (e.g., firmware upload when only monitoring access was approved).
Records all remote sessions with full protocol-level capture for forensic review and regulatory compliance, without introducing latency that would affect OT system operation.
Provides secure remote access to OT environments with no internet connectivity using a data diode-compatible or hardware broker architecture, without requiring an internet-connected OT network.
Checks endpoint health (OS patch level, EDR presence, disk encryption, certificate validity) at each access request, enforcing minimum device security standards before granting application access.
Re-evaluates user and device trust signals throughout an active session, revoking or stepping down access when anomalous behavior is detected, not just at authentication time.
Grants access to individual named applications rather than network segments, users and devices can only reach explicitly authorized applications regardless of network position.
Provides access to browser-based internal applications through a reverse proxy without requiring a device agent, enabling secure access from unmanaged or contractor devices.
