WitnessAI

What the company sells

WitnessAI sells an AI security and governance platform that brings humans and agents under one platform. WitnessAI describes AI agents as a new digital workforce that connects to tools, accesses data and takes actions on behalf of employees. WitnessAI states that, as AI moves from conversations to autonomous actions, enterprises need security and governance that extends from humans to agents.

For the human workforce, WitnessAI names risks around sensitive data, compliance and shadow AI that come from employee use of AI. WitnessAI provides visibility and controls to govern how AI is used. For the agentic workforce, WitnessAI provides visibility into agent activity, control over tool access, and runtime protection for supported agent workflows. WitnessAI says legacy controls like DLP and keyword-based filters were not designed for conversational data, autonomous agents or model-driven workflows.

WitnessAI can find and catalog thousands of AI applications, agents and MCP servers. WitnessAI scans a network for AI usage based on its catalog of thousands of AI applications. WitnessAI shows which AI tools employees use, which agents are running in the environment, and AI spend. WitnessAI can visualize AI conversations, including prompts, responses and agentic activity, in real time.

WitnessAI offers Protect for AI applications, models and agents against security threats. WitnessAI detects and blocks sophisticated attacks, provides runtime agent governance, filters harmful content and chatbot responses, and tokenizes sensitive information. WitnessAI describes its runtime defense as powered by intent-based ML engines that understand context, not just keywords. WitnessAI offers Control for AI usage through intelligent routing, policies and reporting. WitnessAI offers automated red teaming to attack and harden AI models before production deployment.

WitnessAI announced the release of WitnessAI 2.0, with updates for organizations that want to remain compliant with regulations such as PCI DSS while adopting enterprise AI tools. WitnessAI 2.0 includes AI activity controls mapped to PCI DSS 4.0.1, including payment card data loss prevention. WitnessAI says it can detect compromised or malicious user accounts likely to cause data breach or theft by analyzing conversations over time and across AI applications. WitnessAI provides Model Protection, Data Protection and Behavioral Guardrails to help businesses meet requirements of the EU AI Act. WitnessAI announced that it has completed its SOC 2 Type II audit.

WitnessAI is named among the founding members of the ServiceNow Control Tower Alliance, an ecosystem announced by ServiceNow. WitnessAI provides software to securely observe, control, and protect employee and customer use of AI applications. WitnessAI offers analytics on risks from AI usage, threats to users and information, and areas for ROI and operational improvements. TENEX.AI will provide operational and policy expertise using the WitnessAI Secure AI Enablement Platform. TENEX.AI provides managed services for enterprises looking to securely adopt AI and use AI to protect their people and data.^{[1][5][6][7][8][9][10][11][12]}
