Menlo Security is a browser security company that sells a cloud-delivered Browser Security Solution designed to turn any browser into a Secure Enterprise Browser. The approach is unusual: rather than installing software on the endpoint, it creates a hardened digital twin of the user's local browser in the cloud, allowing safe access to the internet, GenAI applications, files and internal applications from any device and browser. Deployment requires no software or infrastructure changes, which the company presents as preserving user choice and productivity alongside security.
Machine learning is central to the product line. Menlo Protect HEAT Shield AI applies AI-driven threat prevention to highly evasive adaptive threats - attacks engineered to slip past network and endpoint tooling - with the stated aim of stopping zero-day exploits before they reach the endpoint or network. The company's technical work spans browser and cloud security, zero-day and phishing and ransomware protection, file sanitisation, secure web gateway and remote browser isolation, and security for GenAI applications.
Menlo Security describes itself as a leader in browser security for over a decade. It reports that 8 of the world's 10 largest banks are customers, and claims full protection against 90% of attacks. Its customer base spans financial services, healthcare, critical infrastructure, federal government, media and entertainment, and automotive. The company operates globally, with a presence in the United States.
