Testing paths, not isolated findings

Specialized agents explore an organization’s attack surface and chain weaknesses together. The output shows a validated route from an initial foothold to broader compromise, along with the systems exposed along that route.

Continuous attack campaigns

The company was running these campaigns for enterprise and government customers at the announcement. The new capital supports expansion of the platform and the research and training behind its agents.

Where the funding goes

  • Scale the security platform, research, agent training and go-to-market operations.
