WitnessAI
WitnessAI is an enterprise AI security and governance platform that gives organizations network-level visibility into every AI interaction across employees, models, applications, and agents. Security and IT leaders use it to discover shadow AI, block prompt injection and jailbreak attacks in real time, and enforce usage policies without browser extensions or endpoint agents.
The platform spans three core modules. Observe catalogs your entire AI footprint and classifies intent across humans and agents. Protect delivers bidirectional runtime defense against threats like prompt injection, harmful outputs, and unauthorized agent actions. Control applies intelligent routing, MCP server governance, and granular audit trails for compliance. WitnessAI also runs automated adversarial testing to harden models before production deployment.
Built for enterprises scaling generative AI and agentic workflows, WitnessAI targets CISOs, security teams, compliance officers, and developers who need to adopt AI without exposing IP, leaking sensitive data, or falling behind on regulatory requirements. Solution tracks cover employee AI usage, developer coding tools, customer-facing applications, and industry-specific compliance needs.

What is WitnessAI?
WitnessAI is an enterprise AI security and governance platform that provides network-level visibility, runtime defense, and policy controls across employees, models, applications, and agents. It helps organizations adopt AI safely by discovering shadow AI usage, blocking attacks like prompt injection, and generating compliance audit trails.
Does WitnessAI require browser extensions or endpoint agents?
No. WitnessAI provides network-level visibility and protection without relying on browser extensions or endpoint clients. It monitors AI activity across your entire network, including native desktop applications like Windows 11 Copilot and Office 365.
What threats does WitnessAI protect against?
WitnessAI protects against prompt injection, jailbreak attempts, harmful model outputs, data leakage, and unauthorized agent actions. Its bidirectional runtime defense blocks threats before they reach AI models and filters responses before users or agents act on them.
Does WitnessAI have a free plan or public pricing?
WitnessAI does not publish pricing on its website. The platform is sold to enterprises through demo requests and contact sales. There is no self-serve free tier listed on witness.ai.
What compliance standards does WitnessAI support?
WitnessAI helps enterprises meet compliance requirements with granular audit trails, real-time sensitive data redaction, and single-tenant deployment for data sovereignty. Its compliance solution specifically references industry regulations like PCI DSS 4.0.1 and supports tracing every agent action to a human identity.
How does WitnessAI govern MCP servers and AI agents?
WitnessAI maintains an organization-wide approved list of MCP servers and tools enforced at the network level for every agent across IDEs, chat apps, and custom-built agents. Blocked tool calls generate audit records with user, agent, tool, and rule details. Organization-level bans cannot be re-enabled by team admins.
Who are WitnessAI's investors?
WitnessAI is backed by Ballistic Ventures, Fin Capital, Forgepoint Capital, Google Ventures, Qualcomm Ventures, Samsung Ventures, and Sound Ventures, as listed on its about page.
