What vArmour does
vArmour was a privately held cybersecurity software company founded in 2011 and headquartered in San Mateo, California, specializing in microsegmentation and Application Relationship Management (ARM). The company's core product mapped dependencies across complex enterprise application environments and enabled fine-grained security zones to support zero-trust architecture adoption. vArmour was recognized as a key player in the global microsegmentation market and was listed alongside major cybersecurity vendors including Cisco, FireEye/Mandiant, and Guardicore. The company also appeared among identified players in the deception technology market, indicating adjacent product positioning around threat detection and response.
vArmour raised approximately $185 million across six funding rounds between 2013 and February 2021, drawing capital from AllegisCyber, NightDragon, Highland Capital Partners, Menlo Ventures, Redline Capital, Citi Ventures, Columbus Nova Technology Partners, Work-Bench, DNX Ventures, Vanedge Capital, Titanium Ventures, EDBI, and SC Ventures. The company employed 101–250 people and primarily served large enterprise organizations seeking zero-trust architecture implementation, regulatory compliance facilitation, and cloud security capabilities, with small and medium enterprises identified as a secondary growth segment. Pricing was not publicly disclosed and the company operated a horizontal go-to-market focused on enterprise sales.
On January 27, 2025, vArmour was acquired by Fenix24, a Chattanooga, Tennessee-based breach recovery and cyber resiliency firm. vArmour's ARM patents and customer base were integrated into Fenix24's Argos99 resilience and operations platform, and the former CEO of vArmour joined Fenix24's advisory board. Following the acquisition, vArmour's standalone operations were absorbed and its public web domain was subsequently parked.
