Menlo Security, a leader in browser security for humans and autonomous AI agents, has launched the industry's first Browser Security Platform specifically designed for the agentic enterprise. In this evolving environment, AI agents are projected to outnumber human employees, with the browser serving as the central operating system for both. The platform delivers a unified control plane for machine-speed governance and threat prevention, deployed on Menlo’s elastic cloud infrastructure, ensuring consistent security across human users and non-human agents without compromising scale or performance.

The launch addresses the rapid shift in enterprise computing, where AI agents automate complex workflows using headless browsers or web protocols—often beyond the reach of conventional security tools. As agents make autonomous decisions inside enterprise systems, new attack vectors like prompt injection via hidden text in documents or steganography emerge, enabling threats invisible to humans.
Securing Humans and Agents with Unified Controls
Menlo’s platform treats humans and AI agents as equivalent participants in the workforce. It moves security enforcement directly into the browser session, creating architectural immunity against evasive threats through cloud-based processing and multimodal visual analysis. This neutralizes attacks before they reach AI reasoning workflows or human endpoints.
Core Capabilities for the Agentic Economy
“The next billion web users won’t be human. This isn't a future prediction; it’s the current reality for the modern enterprise,” said Bill Robbins, CEO of Menlo Security. “By moving protection directly into the browser session, we are enabling organizations to deploy AI agents that work at a scale and speed impossible for humans, without opening the door to catastrophic prompt injection or data exfiltration. Without this protection, a single compromised AI agent can move laterally across enterprise systems, exfiltrate data, or execute fraudulent transactions at machine speed, with no human in the loop."
"Menlo is taking a fresh approach to AI agentic security. Whereas other solutions are trying to chase down agents and build a security perimeter around them, which is a losing battle, Menlo is building governance directly into the agents, securing them from inception,” said Michael D'Arezzo, Executive Director of Information Security and GRC at Wellstar Health System. “This allows for “guardrails” that help users build agents that are secure and have just the right amount of privilege and time to live. Having the confidence that agents are inherently secure from threats and data leakage will help us build out and scale our agentic strategy.”
“AI agents represent a fundamental shift in enterprise computing,” said Ramin Farassat, Chief Product Officer at Menlo Security. “For the first time, security teams have a single control plane that applies the same security and governance policies to an AI agent processing invoices as to the human CFO approving them — at machine speed, with full forensic visibility.”
This announcement follows Menlo’s strong performance, exceeding $140M in ARR with net retention over 120%. It also builds on a recent partnership with Google for least-privileged remote access to desktop applications via the browser, extending zero-trust principles to AI agents across managed, unmanaged, and BYOD devices. By centering security in the browser—the convergence point for identity, intent, and action—Menlo enables enterprises to scale AI adoption confidently while mitigating machine-speed risks.
About Menlo Security
Menlo Security is the pioneer of the Browser Security Platform, the industry’s first infrastructure designed to govern a hybrid workforce of humans and autonomous AI agents. By centering the browser as the new enterprise operating system, Menlo provides a "Guardian Runtime" that resolves the unique risks created when AI agents operate at machine-speed without human skepticism. The Menlo platform enables the agentic enterprise to scale AI with confidence, providing universal connectivity to legacy data and unified zero-day threat prevention across every session. Trusted by over 1,000 global enterprises—including eight of the ten largest financial institutions and major government agencies—Menlo protects over 8 million users and millions of simultaneous AI agent sessions. Headquartered in Mountain View, California, and backed by investors including JPMorgan Chase, American Express Ventures, and Vista Equity Partners, Menlo is securing the browser for the agentic age.
