WitnessAI, the AI security platform trusted by leading enterprises, today announced $58 million in strategic funding. The round was led by Sound Ventures—an early investor in OpenAI, Anthropic, and SentinelOne—with participation from Fin Capital, Qualcomm Ventures, Samsung Ventures, and Forgepoint Capital Partners. The investment will support accelerated global go-to-market efforts and continued product expansion.
Simultaneously, WitnessAI introduced expanded agentic AI governance capabilities that deliver observability and protection for enterprises building and deploying AI agents. As the confidence layer for enterprise AI adoption, WitnessAI secures agents in two key ways.
First, it monitors AI agent activity with the same depth as LLM interactions, tracking active agents, accessed MCP servers and tools, and data shared on behalf of employees or customers. By linking human and agentic identities and capturing runtime context—including agent state and execution commands—WitnessAI provides full explainability for agent actions, creating comprehensive observability across both human and agentic workforces.
Second, the platform extends AI application protection from models to agents, proactively blocking attacks and malicious prompts before they reach the agent. Intent-based behavioral policies understand the meaning and purpose of prompts, enabling precise enforcement that stops advanced threats such as prompt injection or multi-turn attacks. This unified approach secures multi-generational AI applications built on foundational model APIs, custom LLMs, and AI agents.
WitnessAI Agentic Security is available starting January 2026. Technical details are available in the company's blog post.
WitnessAI has established itself as a leading pure-play AI security and governance vendor, with the most comprehensive platform built to secure every AI environment and interaction. In the past 12 months, the company achieved over 500% growth in annual recurring revenue and scaled its headcount by 5x. Its production customers include some of the largest publicly held enterprises across financial services, utilities, automotive, airlines, retail, and telecommunications. This funding round builds on a $27.5 million Series A in May 2024 co-led by Google Ventures and Ballistic Ventures.
"The primary barrier to enterprise AI adoption isn't tech debt; it's tech doubt," said Ashton Kutcher, General Partner at Sound Ventures. "WitnessAI has proven it can instill confidence in AI adoption, and has done so for multiple global leaders. We are thrilled to support the team as they use this capital to expand into new markets and solidify their position as the leading standard for safe, secure enterprise AI."
"The future of AI is hybrid, spanning both cloud and edge. Qualcomm is delivering AI-first experiences across a multitude of devices, where privacy and security are paramount," said Tushar Gupta, Vice President, Qualcomm Technologies Inc., and Managing Director, Qualcomm Ventures North America. "WitnessAI has developed a platform that governs and protects AI agents, models, applications, and users—wherever they operate. We're excited to invest in WitnessAI as they build the essential infrastructure for the agentic era."
"Enterprises are just getting started with mobile AI," said a Samsung Ventures Vice President. "As models move from the cloud to the device, security organizations will require AI controls that protect devices as well as corporate desktops and servers. WitnessAI has built an architecture that can scale to handle global enterprise AI adoption, and we are happy to be part of that journey."
"Financial Services often leads the way in new technology adoption, and AI is no exception," said Logan Allin, Managing Partner at Fin Capital, investing from its SMBC Fin Atlas Beyond Fund. "We believe that WitnessAI is poised to be the category leader in secure AI adoption for financial services institutions of all sizes across banks, asset and wealth managers, and insurers, all of whom are crossing the chasm and must do so with a robust bridge."
"AI adoption in financial services requires not only innovation but also the highest standards of security and accountability," said Keiji Matsunaga, General Manager of the Digital Strategy Department at SMBC. "As one of Japan's leading financial institutions, SMBC sees great significance in supporting WitnessAI's growth as it advances responsible AI implementation."
"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."
