WitnessAI, the AI security platform trusted by major enterprises, has raised $58 million in strategic funding to accelerate its global expansion and enhance its AI governance solutions. The round was led by Sound Ventures, an early backer of OpenAI and Anthropic, with participation from Samsung Ventures, Qualcomm Ventures, Fin Capital, and Forgepoint Capital Partners. The company also announced new features that bring enhanced observability and protection to enterprise AI agents.
Strengthening Agentic AI Security
WitnessAI has introduced expanded capabilities to secure AI agents in addition to traditional AI models. Its platform now monitors agent activity, tracking access to servers, tools, and data, while linking human and agentic identities to provide full visibility into decisions made by autonomous systems. This integration of human and agent contexts enables enterprises to understand the rationale behind agent actions, delivering a new level of explainability across AI operations.
The platform also extends protection from AI models to agents by preventing attacks and malicious prompts before they reach the system. It supports multi-generational AI applications, including custom LLMs, foundational model APIs, and AI agents, ensuring comprehensive security across evolving AI workflows. WitnessAI’s policy engine evaluates behavioral intent, enabling accurate enforcement against advanced threats like prompt injection or multi-turn attacks, strengthening enterprise confidence in AI adoption.
Rapid Growth and Enterprise Adoption
WitnessAI has rapidly scaled over the past year, reporting more than 500% growth in annual recurring revenue and a fivefold increase in headcount. Its platform is already deployed by large enterprises across sectors such as financial services, utilities, automotive, airlines, retail, and telecommunications. The latest funding provides additional resources to expand into new markets while solidifying partnerships that will support global adoption of the company’s AI security solutions.
This round follows a $27.5 million Series A in May 2024 co-led by Google Ventures and Ballistic Ventures, underscoring sustained investor confidence. According to Ashton Kutcher, General Partner at Sound Ventures, enterprise AI adoption often falters due to uncertainty rather than technical challenges. He emphasized that WitnessAI has proven it can instill trust in AI systems, enabling organizations to deploy AI safely at scale.
Investor Perspectives on AI Security
Qualcomm Ventures highlighted the importance of AI governance across cloud and edge devices, stressing that security and privacy are critical for AI-first experiences. Samsung Ventures echoed this sentiment, noting that as AI moves from cloud to device, enterprises require robust protection for mobile and desktop environments alike. Fin Capital and SMBC representatives emphasized the significance of secure AI adoption in financial services, citing the need for trustworthy platforms to support banks, insurers, and asset managers as they integrate AI into critical workflows.
A Unified Approach to AI Protection
WitnessAI CEO Rick Caccia explained that their platform is the only solution capable of securing all AI interactions with a unified approach. He contrasted this with traditional security measures, which rely on fragmented tools like firewalls, proxies, and DLP systems, often resulting in complex and incomplete protection. WitnessAI’s architecture simplifies enterprise AI security while ensuring comprehensive coverage and compliance, transforming AI risk management from a challenge into a strategic enabler.
The launch of WitnessAI’s agentic security features marks a significant step in safeguarding enterprise AI ecosystems. With this new funding and enhanced capabilities, the company is positioned to support global enterprises in deploying AI responsibly and securely. WitnessAI continues to strengthen its role as the confidence layer for enterprise AI, delivering visibility, governance, and protection for both human and autonomous agents.
