Menlo Security today unveiled a new Browser Security Platform purpose-built to secure the emerging "agentic enterprise." As autonomous artificial intelligence agents increasingly outnumber human employees, the browser has become the primary operating system for both.
The offering provides a unified control plane to apply machine-speed governance and threat prevention to human and non-human actors alike. Traditional security often misses headless browsers or web protocols used by AI agents. Menlo argues this transition invites attacks invisible to the human eye, such as prompt injection via documents.
The platform treats humans and agents as equal participants. It enforces instruction-data separation to ensure agents never mistake malicious data for legitimate commands. Universal connectivity translates legacy web interfaces into sanitized data, while deterministic visibility offers real-time session-flow views.
Ramin Farassat, Chief Product Officer, stated that security teams now have a single control plane applying policies to an AI agent processing invoices as to the human CFO approving them. Menlo Security has raised $250 million in funding, including investments from Vista Equity Partners and JPMorgan Chase.
