Menlo Security

Founded over a decade ago, Menlo Security is a global cybersecurity leader. Trusted by over 1,000 enterprises—including Fortune 500 companies and large government agencies—to protect eight million users, Menlo created the industry's first Browser Security Platform. Our platform transforms standard browsers into secure enterprise browsers using a synergistic architecture that combines local controls with the Menlo Secure Cloud Browser. Key capabilities include Adaptive Clientless Rendering (ACR) for safe cloud execution, H.E.A.T Shield AI to block zero-hour phishing, clientless Zero Trust access, and Data Loss Prevention (DLP) with Content Disarm and Reconstruction (CDR). Menlo delivers architectural immunity against evasive threats for both humans and autonomous AI agents. By solving the "Agentic Paradox," we prevent data exfiltration and block zero-day ransomware. Organizations can safely govern Generative AI, secure unmanaged BYOD endpoints, and replace costly VDI and VPNs—all without disrupting user productivity.
