About the Company

Agile Defense

Cybersecurity and IT services for government

Agile Defense provides IT and cybersecurity services to the U.S. Federal Government, including digital transformation, IT modernization, and a Virtual Security Operations Center (VSOC) to defend against cyber threats. Its services support national security and civilian missions across federal agencies, delivered through various contract vehicles. The company expands its capabilities through acquisitions (IntelliBridge and XOR Security) and focuses on AI-enabled workforce transformation and enterprise IT to enhance government operations. Unlike many suppliers, Agile Defense emphasizes a government-focused portfolio with a multidimensional VSOC and AI-driven workforce upgrades, positioning itself to meet federal security and modernization needs. The goal is to help federal agencies protect data and systems, modernize IT infrastructure, and improve cyber resilience across national security and civilian missions.
