Process orchestration leader earns highest unclassified level of authorization to deliver secure, intelligent automation for mission-critical warfare operations

MCLEAN, Va., Oct. 29, 2026 /PRNewswire/ -- Appian today announced that the Appian Defense Cloud (ADC) achieved Impact Level 5 (IL5) Provisional Authorization to Operate (PA) from the United States Department of War (DOW). Building on Appian's IL5 Appian Government Cloud (AGC) offering, this accreditation enables DOW agencies to deploy mission-critical workloads using Appian's intelligent process automation innovations with enterprise-grade security.

"Achieving IL5 for our next generation platform - ADC marks a significant milestone for Appian in providing the DOW with mature and secure intelligent process automation to support warfighter operations," said Michael Beckley, Chief Technology Officer at Appian. "The production-ready platform represents an evolution of Appian's long-standing defense capabilities, bringing modern agentic intelligence and process orchestration directly to mission operations with enterprise-grade guardrails."

Appian's defense heritage began with its contract to architect Army Knowledge Online (AKO) more than two decades ago, which grew into one of the world's largest military intranets. As one of the first cloud service providers to achieve FedRAMP authorization in 2015, Appian has demonstrated continuous mastery of meeting continuous monitoring and security compliance requirements across public sector environments.

This latest designation recognizes the operational maturity of the Appian Platform and the DOW's continued trust for it to provide industry-leading security and availability across high-impact warfare operations. With IL5 designation, ADC can store and process the DOW's highest-sensitivity unclassified information, mission-critical data, and unclassified national security systems.

Scale and deployment across US defense

Appian's defense footprint scaled almost 4x in deployment volume over the last 12 months. Today, Appian supports:  

• 2,000,000+ active DOW & IC users relying on the platform for daily operations. 
• 100+ mission platforms running mission-critical automation.  
• Supporting key operational communities, including contract writing, legal case management, intelligence and security, foreign military sales, and logistics and maintenance.  

Key fielded capabilities include 12 prominent Army programs in production, including the Total Army Combat and Training Munitions Information System (TACTMIS) for the US Army. Created in 110 days from contract award to support more than 10,000 active users worldwide, TACTMIS delivers speed and value for training and operational missions. By unifying munitions management processes across the Active Army, Army National Guard, US Army Reserve, and joint partners, TACTMIS provides the scale, security, and visibility needed to support Army-wide readiness and senior-leader decision-making.

Defense-grade capabilities for DOW-compliance

• Orchestrated agentic intelligence: Native capabilities for agent-assisted workflow creation, intelligent document processing (IDP), generative capabilities, and agentic insights.
• Data fabric: Connects disparate data sources without moving core records, giving agents and users immediate context.
• Process intelligence: Real-time process monitoring and analytics to track operational efficiency and auditability.
