Menlo Security

Menlo Security is a cybersecurity company that provides cloud-delivered browser security. Its platform transforms any browser into a Secure Enterprise Browser by creating a hardened digital twin of the user's local browser in the cloud, protecting users and enterprises from internet-borne threats. The approach requires no software or infrastructure changes on the client side, allowing safe internet access, GenAI application usage, file opening and application access from any device and browser. The company operates globally.

Two products anchor the offering. The Cloud-delivered Browser Security Solution provides the digital-twin architecture described above. Menlo Protect HEAT Shield AI is an AI-driven layer designed to stop Highly Evasive Adaptive Threats (HEAT) that bypass network and endpoint tools, including zero-day exploits, before they reach the endpoint or network. Technical work at the company spans browser security, cloud security, AI-driven threat prevention, zero-day threat protection, file sanitisation, phishing and ransomware defence, and secure web gateway and isolation technology.

Menlo Security states that it has been a leader in browser security for over a decade. Its customers include Fortune 500 corporations and 8 of the world's 10 largest banks, and the company claims full protection against 90% of attacks. Industries served include financial services, banking, healthcare, critical infrastructure, federal and government, media and entertainment, and automotive.

The company describes itself as innovation-focused, with continued investment in AI-driven solutions, and emphasises preserving user choice and productivity alongside security.
