As agentic enterprise deployments grow, Menlo Security delivers the only platform that secures both humans and AI agents, as attackers exploit the gap.
MOUNTAIN VIEW, Calif.–(BUSINESS WIRE)– Menlo Security, the leader in human and agentic Browser Security, today announced the first Browser Security Platform purpose-built to secure the agentic enterprise; where autonomous AI agents will outnumber human employees and the browser has become the operating system for both.
Menlo provides the first unified control plane to apply machine-speed governance and threat prevention to both human and non-human actors, deployed globally on Menlo’s elastic cloud infrastructure.
“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.”
This launch follows a record fiscal year for Menlo, which surpassed $140M in ARR with net retention exceeding 120%. To further accelerate market leadership, Menlo recently partnered with Google to deliver least-privileged remote access to desktop applications and data via the browser for humans and agents. This allows organizations to eliminate the cost and operational complexity of traditional VDI, extending Menlo’s zero-trust controls to AI agents, and any managed, unmanaged, or BYOD device.
Securing the “Agentic” Age
Enterprises are now deploying AI agents to automate complex workflows, but these agents often utilize headless browsers or leverage web protocols directly, operating entirely outside the scope of traditional security technologies.
“The enterprise workforce is changing. AI agents are now making decisions inside enterprise systems, yet most security programs were never designed to account for them,” said Antonio Bovoso, Founder & Principal at Consiro Advisory. “The browser is where agent identity, intent, and action converge, making it a critical control point in the enterprise.”
Threat actors are already exploiting this transition with attacks invisible to the human eye, such as prompt injection via documents and steganography. For example, an AI agent tasked with processing an invoice could unknowingly ingest hidden malicious instructions within a file, redirecting payments to fraudulent accounts while appearing legitimate to human supervisors.
The Menlo Browser Security Platform resolves this by treating humans and agents as equal participants in the workforce, providing:
• Menlo AI Agent Security: Acts as a “Guardian Runtime” for the agentic economy, enforcing instruction-data separation to prevent malicious command execution and data exfiltration.
• Universal Connectivity: Enables AI agents to interact with legacy systems and data sources lacking modern APIs, while ensuring data is sanitized before use.
• Deterministic Visibility: Provides deep forensic insights and real-time session visibility at the browser and file component level.
• Least-Privileged Agent Governance: Applies granular controls to prevent unauthorized access, lateral movement, and data extraction.
Architectural Immunity for Humans and Agents
The platform embeds security directly into the browser session, creating what Menlo calls “Architectural Immunity” — where threats are neutralized before they can execute. This is achieved through cloud-based runtime processing and multimodal analysis before data reaches AI systems or human users.
“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.”
Menlo Security will showcase the Browser Security Platform at RSAC 2026. For more information, visit https://www.menlosecurity.com/lp/menlo-rsa.
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 addresses the risks of AI operating at machine speed without human oversight.
The platform enables enterprises to scale AI securely, providing universal connectivity to legacy systems 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 leading investors, Menlo is securing the browser for the agentic age.
