- 174
- Series B
The platform gives enterprises visibility into AI assets across their environments, validates model integrity before deployment, and detects attacks on AI systems running in production. It is built specifically for AI-specific threats rather than adapted from general cybersecurity tools, and deploys without requiring access to model weights, prompts, or training data.
The professional services team conducts adversarial red-team testing against agentic, generative, and predictive AI applications, assesses AI supply-chain and data-pipeline risk against compliance frameworks, and trains security and development teams to recognize AI-specific threats. Engagements produce prioritized remediation playbooks and before-and-after security-posture scoring.
