What Menlo Security does
Menlo Security is a private, Mountain View-based cybersecurity company founded in 2012 that builds the Menlo Browser Security Platform, a hybrid cloud-delivered system combining a local browser extension (Menlo Secure Extension) with cloud-based isolation and rendering in the Menlo Cloud to secure enterprise browsing for both human users and autonomous AI agents. The platform is built around several integrated modules: Threat Prevention (HEAT Shield AI, which combines proprietary multimodal visual page analysis with Google Gemini generative AI to detect zero-day phishing and highly evasive adaptive threats), AI Agent Security (Menlo Agent Runtime Security / MARS) that executes agent sessions in disposable cloud containers to strip prompt injection and steganography, File Security using patented Positive Selection Content Disarm and Reconstruction across 220+ file types, AI Adaptive DLP for real-time sensitive data masking, Secure Application Access for clientless zero-trust access replacing VPN and VDI, plus Browsing Forensics, Browser DLP, and Remote Browser Isolation. The company monetizes primarily through enterprise SaaS subscriptions on the Menlo Browser Security Platform, with additional per-seat pricing for Secure Application Access and usage-based consumption via the AWS Marketplace for File Security on S3; pricing is quote-based and not publicly disclosed. Menlo sells primarily through direct enterprise field sales supported by strategic partnerships with Google (Cameyo, Google Cloud, Gemini), AWS, Bugcrowd, and DSO National Laboratories, and serves 1,000+ global enterprises including 8 of the 10 largest financial institutions and major federal agencies such as DISA, with documented customers across financial services, healthcare, defense, telecom, logistics, energy, and government verticals. The company surpassed $140M in ARR with net retention above 120% in its most recent fiscal year and is backed by Vista Equity Partners, JPMorgan Chase, and American Express Ventures.

Menlo Security product offering
Product offeringCore offering
Menlo Security builds and sells a cloud-delivered Browser Security Platform that secures both human users and autonomous AI agents through a single control plane. The platform combines a browser-native Secure Extension on the endpoint with the Menlo Cloud, which performs high-risk browsing isolation, AI-driven threat prevention (HEAT Shield AI), Content Disarm and Reconstruction (CDR) file sanitization, AI Adaptive Data Loss Prevention, and clientless zero-trust application access as a replacement for VPN and VDI.
Product overview
Menlo Security offers the Menlo Browser Security Platform, a unified platform-plus-modules architecture designed to deliver "architectural immunity" for both human users and AI agents. The core platform is the Menlo Browser Security Platform, which provides a single control plane integrating cloud-based isolation (Menlo Cloud) and a browser extension (Menlo Secure Extension). Built around it are several integrated modules: AI Agent Security (Menlo Agent Runtime Security / MARS) for securing autonomous AI agents; AI Adaptive DLP for real-time sensitive data masking; Threat Prevention (HEAT Shield AI) for AI-powered zero-day threat defense; File Security (CDR via Positive Selection) for sanitizing 220+ file types; Remote Access (Menlo Secure Application Access / SAA) for clientless zero-trust application access as a VPN/VDI replacement; Secure Enterprise Browser for hybrid protection of any browser; plus Browsing Forensics, Browser DLP, and Remote Browser Isolation. Together these modules treat humans and AI agents as equal participants, applying unified governance, threat prevention, and data protection across every browser session.

Products and services
- Menlo Browser Security Platform Unified cloud-delivered platform that delivers architectural immunity for both humans and AI agents through a single control plane with elastic cloud scale, combining the Menlo Cloud for high-risk browsing with the Menlo Secure Extension for local controls.
- AI Adaptive DLP AI-based detection and masking of sensitive data (PII, PHI, financial/PCI data, and corporate IP) in real time, without blocking files; masks only sensitive data while leaving files otherwise pristine and available for consumption.
- AI Agent Security (Menlo Agent Runtime Security / MARS) Guardian Runtime that executes all agent browser sessions in remote, disposable containers in the Menlo Cloud, stripping malicious scripts, hidden instructions, and steganography from pages and files before agents process them; secures autonomous agents and integrated browser agents such as Copilot and Gemini.
- Menlo File Security Proactive file sanitization using patented Positive Selection technology and Content Disarm and Reconstruction (CDR) across 220+ file types, automatically disarming and rebuilding files (including archives and password-protected files) before they reach user endpoints or AI agents.
- Menlo Secure Application Access (SAA) Clientless zero-trust application access delivered through any standard browser for SaaS, private, and legacy thick-client applications; enforces least-privileged access and replaces VPNs and VDI, with integrations to major identity providers such as Okta, Microsoft Entra ID, and Google Workspace.
- Menlo Secure Enterprise Browser Hybrid Secure Enterprise Browser that combines the Menlo Secure Extension for local DLP controls and visibility with the Menlo Cloud for air-gapped isolation of high-risk browsing, supporting major browsers including AI-native browsers and embedded browser agents.
- Threat Prevention (HEAT Shield AI) AI-powered proactive defense that stops zero-day exploits via multimodal visual analysis of web pages, DOM inspection, and Google Gemini generative AI analysis to neutralize highly evasive threats before they reach the endpoint.
- Browsing Forensics Forensic-level visibility into user activity within applications with video-like session recordings, code-level views of exploits, and SIEM/SOC integration for incident investigation and compliance auditing.
- Browser DLP Browser-centric data loss prevention controls including copy/paste restrictions, file upload/download controls, watermarking, and dictionary DLP for web fields and files, preventing data exfiltration across managed and unmanaged devices.
- Remote Browser Isolation Cloud-based browser isolation that renders web content in the Menlo Cloud and delivers safe HTML to user endpoints, eliminating zero-day browser-borne threats reaching local devices.
