Simplify's Take

What believers are saying

  • GDIT’s March 25, 2026 $120 million Air Force NGG task order validates AppGate’s ZTNA.
  • AppGate launched OT ZTNA on March 23, 2026, targeting critical infrastructure operators.
  • Agentic AI Core Protection, launched December 18, 2025, extends AppGate into AI workload security.

What critics are saying

  • Headcount fell 11.2% from 2023 to 2026, signaling a shrinking operating base.
  • AppGate stayed private after 2024 recapitalization, limiting transparency and raising financing dependency.
  • Palo Alto, Zscaler, and Microsoft can bundle access and OT security, compressing AppGate’s pipeline by 2027.

What makes AppGate Cybersecurity unique

  • AppGate’s direct-routed ZTNA avoids cloud hairpinning, preserving latency-sensitive OT and defense traffic.
  • NIAP, FIPS 140-3, Common Criteria EAL2+, and SOC 2 Type 2 strengthen trust.
  • AppGate sells into defense, federal, and industrial environments where compliance trumps generic access tools.

AppGate partners with GDIT to provide Zero Trust Network Access for U.S. Air Force next Generation Gateway program.

AppGate partners with GDIT to provide Zero Trust Network Access for U.S. Air Force next Generation Gateway program. Industry-Leading ZTNA Solution is Part of GDIT's $120M NGG Task Order, Securing Over a Million Users Across 187 Air Force Bases Worldwide NEW YORK & SAN FRANCISCO-(BUSINESS WIRE)-AppGate, a global leader in Zero Trust Network Access (ZTNA) solutions, today announced that it will provide its industry-leading ZTNA solution as part of General Dynamics Information Technology's (GDIT) $120 million U.S. task order to modernize cybersecurity across U.S. Air Force bases worldwide. The announcement was made at the RSAC 2026 Conference. As the Air Force and its mission partners accelerate Zero Trust adoption, AppGate remains focused on enabling secure, scalable access that strengthens cyber resilience and protects national security. Share The U.S. Air Force NGG program represents one of the largest Zero Trust modernization efforts across the Department of Defense, supporting over one million users across 187 bases globally and protecting information at all levels of classification. AppGate's ZTNA solution is purpose-built to support NGG mission requirements by enforcing identity centric, least privilege access across distributed, global, and disconnected environments. AppGate's ZTNA solution will enable the U.S. Air Force to: * Ensure interoperability with its mission partners * Increase its lethality * Secure its warfighters and enterprise users "Next Generation Gateway is redefining how Zero Trust is operationalized at scale," said Leo Taddeo, CEO of AppGate. "AppGate's ZTNA solution is purpose-built for defense and federal missions that require high assurance, operational resilience, and the ability to operate across global, classified and tactical environments." AppGate ZTNA ensures Zero Trust by dynamically establishing direct-routed, encrypted connections between authorized users and approved resources, while remaining invisible to unauthorized actors. AppGate keeps policy enforcement within the mission boundary, delivering superior performance, reduced attack surface, and mission continuity - even in degraded or disconnected conditions. AppGate's ZTNA solution is certified by the National Information Assurance Partnership (NIAP), validating compliance with federal security standards and reinforcing its suitability for sensitive government and defense deployments. The NGG task order awarded to GDIT underscores the Air Force's commitment to advancing Zero Trust architectures that combine identity, data centric security, and advanced threat detection to meet the Department of War's Zero Trust mandate ahead of the 2027 deadline. "As the Air Force and its mission partners accelerate Zero Trust adoption, AppGate remains focused on enabling secure, scalable access that strengthens cyber resilience and protects national security," Taddeo added.

AppGate launches OT ZTNA solution to secure industrial control systems and critical infrastructure.

AppGate launches OT ZTNA solution to secure industrial control systems and critical infrastructure. March 24, 2026 AppGate announced the launch of its OT (operational technology) ZTNA product offering that secures industrial control systems, manufacturing plants, energy facilities, and other critical infrastructure environments. It extends AppGate's direct-routed ZTNA architecture into OT networks, enabling secure remote access without disrupting performance or operational stability. As IT and OT systems grow increasingly interconnected, remote access has become fundamental to industrial operations. This shift challenges legacy security models that were designed for isolated networks. VPN-based connectivity, which typically grants wide network access, can unintentionally expand risk by exposing more of the environment than necessary. AppGate ZTNA addresses this challenge by shifting access control from the network to the identity layer, verifying users and enforcing policy before any connection is permitted. Systems are not openly exposed, and users are granted access only to the precise resources required to perform their work. By enabling direct, encrypted connections to authorized OT systems, AppGate ZTNA helps preserve the performance and operational stability industrial environments demand. AppGate's new OT offering provides several capabilities designed specifically for industrial operations. These capabilities include alignment with industrial security frameworks, supporting access control principles consistent with IEC 62443, NIST SP 800-82, and the latest NERC CIP-015-1 requirements, which helps organizations strengthen OT and bulk electric system cybersecurity while maintaining operational continuity. The approach also ensures cloaked infrastructure, where industrial assets remain invisible to unauthorized users through a default-deny posture, preventing the exposure of internal IP addresses and services. Connectivity is handled through direct-routed encrypted sessions established between users and authorized resources, operating fully on premises to preserve air gaps and avoid centralized cloud backhaul that could introduce latency or affect availability. In addition, secure third-party access control is enabled through granular policies that provide just-in-time access to specific systems for contractors and vendors. "In highly regulated industries, remote access must be immediate and tightly controlled, without breaking the air gap or relying on shared cloud infrastructure," said Nitin Pillai, CTO at AppGate. "Building on our experience with enterprise-scale deployments in defense and critical infrastructure, AppGate is the first to deliver native, on-prem, direct-routed secure access to production environments, bridging IT and OT security while prioritizing performance and reliability." As remote connectivity becomes embedded in industrial operations, unmanaged access represents a material business risk. AppGate ZTNA for OT provides an identity-centric, direct-routed approach that reduces the attack surface, strengthens oversight, and protects mission-critical systems. It is a deliberate step forward in securing the infrastructure that drives industrial performance and business continuity. Secure Remote Access for Industrial OT is now generally available for customers. Industrial Cyber News Desk
