Vectra AI

Vectra AI is an AI-driven threat detection and response company headquartered in San Jose, California, specializing in network detection and response (NDR), identity threat detection, and hybrid cloud security. Founded in 2011, Vectra has raised a total of $352 million across multiple funding rounds including a Series F.

The company's Cognito platform—now the AI-driven Vectra AI Platform—uses patented Attack Signal Intelligence to correlate telemetry across network, identity (Active Directory and Azure AD), cloud, and SaaS environments, surfacing only the most urgent threats to reduce alert fatigue. Vectra was named a Leader in the 2025 Gartner Magic Quadrant for Network Detection and Response and recognized in the Forrester Wave for Network Analysis and Visibility.

The platform operates without decryption of traffic, using behavioral AI trained on real attacker behavior rather than signatures, enabling detection of lateral movement, privilege escalation, command-and-control, and data exfiltration even in encrypted environments. Vectra's customers include organizations across financial services, healthcare, critical infrastructure, education, and government sectors in more than 113 countries.

The company integrates with leading SIEM, SOAR, and EDR vendors including Microsoft Sentinel, Splunk, CrowdStrike, and SentinelOne. Vectra AI holds SOC 2 Type II certification and supports GDPR, CCPA, and HIPAA compliance requirements.

The company employs approximately 500–700 people globally.
