Security agents with application context

General Security Intelligence examines a company’s software and infrastructure together, rather than treating each potential weakness as an isolated alert. The platform is designed to detect vulnerabilities, triage their significance and help remediate them.

Growing research and customer delivery

The capital supports research and development, go-to-market work and hiring in applied research, engineering, product and sales. Accel also published a separate account of its investment, describing agents that understand business logic and suggest fixes.
