WitnessAI Secures $58M in Funding, Announces Global Expansion and New Tools to Protect AI Agents
WitnessAI, an AI security platform trusted by leading enterprises, announced it has secured strategic funding of $58 million, enabling the company to accelerate its global go-to-market and product expansion.
Led by Sound Ventures, an early investor in OpenAI, Anthropic, and SentinelOne, and with participation from Fin Capital, Qualcomm Ventures, Samsung Ventures, and Forgepoint Capital Partners.
This latest funding accelerates the company's trajectory, providing the resources required to scale and new strategic partners to drive growth into new markets. WitnessAI last raised $27.5 million in a Series A funding round in May 2024, co-led by Google Ventures and Ballistic Ventures.
The company also unveiled expanded agentic AI governance capabilities that bring observability to global enterprises developing and deploying AI agents.
WitnessAI provides the confidence layer for enterprise AI adoption. The leading AI security platform extends to secure agents in two novel ways. The first is securing AI agent activity similarly to LLM activity, monitoring which agents are active, what MCP servers and tools they are accessing, and what data they are sharing. WitnessAI can see what an agent is doing on an employee's or customer's behalf, according to the company.
By connecting the human and agentic identities and capturing the evolving decision-making context, including agent state and execution commands at runtime, WitnessAI provides explainability for agent actions. This creates powerful observability across both workforces, human and agentic.
The second is extending AI application protection from AI models to agents, safely blocking attacks and malicious prompts before they reach the agent. These capabilities enable the protection of multi-generational AI apps, built on foundational model APIs, custom LLMs, and AI agents, the company said.
WitnessAI Agentic Security is available in January 2026.
"AI workflows are maturing and starting to cross corporate and cloud LLMs and agents," said Rick Caccia, co-founder and CEO at WitnessAI. "We are the only AI security vendor that can secure every AI interaction, everywhere, with a unified solution. The alternative is trying to stitch together secure workflows using network proxies, firewalls, DLP products, and XDR agents. In short, the alternative is a complex mess."
