WitnessAI Raises $58M to Expand AI Security Platform

WitnessAI has raised $58 million in fresh funding to accelerate the global expansion of its AI security platform, as enterprises struggle to secure rapidly growing use of large language models (LLMs) and autonomous AI agents. The capital will be used to scale its AI network and agent protection capabilities, build MSSP-ready offerings, and help organisations detect and control unauthorised AI usage across employees and customers.

The funding comes at a critical moment. As generative AI tools and agentic workflows become embedded in day-to-day business operations, security teams are losing visibility into how data flows through AI systems. Traditional cybersecurity tools were not designed to monitor prompts, responses, model interactions, or third-party AI agents operating outside sanctioned environments. WitnessAI is positioning itself as a control layer for enterprise AI, rather than just another security add-on.

At the core of WitnessAI’s platform is continuous monitoring of AI interactions across popular LLMs, internal copilots, and external AI services. The system detects policy violations such as sensitive data leakage, use of unapproved AI agents, or prompts that could expose intellectual property or regulated information. By extending these capabilities to MSSPs, WitnessAI aims to embed AI security into managed services, allowing enterprises to scale protection without expanding in-house teams.

Strategically, the company is also betting on the rise of AI agents—autonomous systems that can take actions, call tools, and interact with other software. While agents promise productivity gains, they also introduce new risks, including uncontrolled decision-making and shadow AI deployments. WitnessAI’s focus on agent detection and governance reflects a broader industry shift from securing “AI tools” to securing AI-driven behaviours.

The investment highlights growing investor confidence in AI-native security companies. As regulators scrutinise AI use and enterprises face mounting compliance pressure, demand is rising for platforms that can enforce consistent policies across diverse AI environments.

In essence, WitnessAI’s $58 million raise underscores a key reality of the AI era: as adoption accelerates, AI security is becoming a foundational requirement, not an optional layer. Companies that can provide visibility, control, and trust across AI systems may become as critical as endpoint and cloud security providers were in previous technology waves.
