As enterprises race to deploy AI agents that can act, decide, and execute autonomously, a new problem is becoming impossible to ignore: no one really knows what those agents are doing once they’re live. WitnessAI is betting that this visibility gap—not model quality—will be the biggest blocker to enterprise AI adoption.
The AI security and governance company announced $58 million in new strategic funding, led by Sound Ventures, with participation from Fin Capital, Qualcomm Ventures, Samsung Ventures, Forgepoint Capital Partners, and others. Alongside the funding, WitnessAI unveiled expanded agentic AI governance and security capabilities designed to bring real-time observability, explainability, and policy control to enterprises deploying AI agents at scale.
The message is clear: AI agents are moving from experiments to production, and existing security tools aren’t built to manage autonomous systems that reason, act, and interact across cloud, edge, and enterprise environments.
Why Agentic AI Changes the Security Equation
Until recently, enterprise AI security largely revolved around large language models (LLMs): monitoring prompts, preventing data leakage, and blocking malicious inputs. Agentic AI breaks that model.
Agents don’t just respond—they act. They call tools, access MCP servers, move data, trigger workflows, and make multi-step decisions on behalf of employees and customers. Traditional security tools—firewalls, DLP, network proxies, even XDR—lack the context to understand intent or trace accountability across these actions.
WitnessAI is positioning itself as the “confidence layer” for this new AI architecture. Its expanded platform treats AI agents not as black boxes, but as first-class entities with identities, behaviors, and audit trails.
Observability for Both Human and AI Workforces
The first major capability WitnessAI announced is deep observability into agent activity. The platform monitors which agents are active, what tools and MCP servers they access, what data they touch, and how their decisions evolve in real time.
Crucially, WitnessAI connects human identities with agentic identities. That linkage allows enterprises to see not just what an agent did, but who—or what—authorized or triggered the action. By capturing agent state, execution commands, and decision-making context at runtime, the platform provides explainability that’s increasingly demanded by regulators, auditors, and internal risk teams.
In practical terms, this creates a single view across both human and agentic workforces—an important shift as enterprises begin treating AI agents as operational actors rather than software features.
Blocking Attacks Before Agents Act
The second major expansion extends WitnessAI’s AI application protection layer from models to agents themselves. Instead of focusing only on model inputs and outputs, the platform can now intercept and block malicious prompts or attacks before they ever reach an agent.
This is especially important as enterprises build multi-generational AI applications—systems that combine foundational model APIs, custom LLMs, and autonomous agents. These architectures are powerful, but they also expand the attack surface dramatically.
WitnessAI’s differentiator is policy enforcement based on behavioral intent. Rather than relying on static rules or keyword filtering, the platform analyzes the meaning and intention behind prompts and actions. That enables it to stop advanced threats such as prompt injection, multi-turn attacks, and agent manipulation that would bypass conventional defenses.
WitnessAI Agentic Security is slated for availability in January 2026, signaling that the company is targeting enterprises already planning large-scale agent deployments—not hypothetical future use cases.
Growth Signals a Market Crossing the Chasm
The funding announcement comes amid rapid growth. Over the past 12 months, WitnessAI reports more than 500% growth in annual recurring revenue and a 5x increase in employee headcount. Its platform is already protecting hundreds of thousands of enterprise employees and AI applications in production environments.
Customers span highly regulated and high-risk sectors including financial services, utilities, automakers, airlines, retailers, and telecommunications—industries that typically adopt new technology cautiously and only when governance is airtight.
That customer profile reinforces a broader trend: enterprise AI adoption is no longer about innovation teams. It’s about risk, compliance, and operational resilience at board-level scale.
Investors Are Betting on Trust, Not Hype
Sound Ventures’ leadership of the round is notable. The firm has backed OpenAI, Anthropic, and SentinelOne—companies that defined categories rather than chased incremental improvements.
“The primary barrier to enterprise AI adoption isn’t tech debt; it’s tech doubt,” said Ashton Kutcher, General Partner at Sound Ventures. That framing cuts to the heart of the issue: enterprises aren’t blocked by infrastructure—they’re blocked by fear of unintended consequences.
Other investors echoed that sentiment from different angles. Qualcomm Ventures highlighted the shift toward hybrid AI spanning cloud and edge environments, where governance must travel with the model. Samsung Ventures pointed to mobile and on-device AI, where agents will increasingly operate outside traditional corporate perimeters. Fin Capital and SMBC emphasized the stakes in financial services, where accountability and auditability aren’t optional.
Taken together, the investor lineup underscores a belief that AI security will become core infrastructure—not an add-on—especially as agents proliferate.
A Unified Alternative to a “Complex Mess”
WitnessAI CEO and co-founder Rick Caccia was blunt about the alternatives. Without a unified AI security platform, enterprises are forced to stitch together workflows using legacy tools never designed for autonomous systems.
“The alternative is a complex mess,” he said, pointing to brittle combinations of network proxies, firewalls, DLP products, and endpoint agents. Those tools may secure data paths, but they can’t reason about AI intent or agent behavior.
WitnessAI’s pitch is that AI security requires its own native control plane—one that understands prompts, models, agents, users, and data as part of a single system.
Why This Matters Now
Agentic AI is moving faster than most governance frameworks. Enterprises are already experimenting with agents that handle customer interactions, code changes, financial analysis, and operational workflows. Regulators, meanwhile, are sharpening their focus on accountability, explainability, and risk management.
WitnessAI’s timing suggests it sees a narrow window: either enterprises establish control now, or they repeat the early mistakes of cloud and SaaS adoption—where governance lagged deployment by years.
With $58 million in fresh capital, deep-pocketed strategic investors, and a product roadmap aimed squarely at agentic AI, WitnessAI is making a strong bid to define the security standard for the next phase of enterprise AI.
Whether it succeeds will depend on how quickly enterprises realize that AI agents aren’t just smarter software—they’re new actors in the enterprise, and they need to be governed accordingly.
