Menlo Security provides cloud-based security solutions centered around its patented Isolation Core technology. This technology creates an "air gap" between users and the internet, isolating the browsing process in the cloud to protect against web-based threats like phishing, drive-by exploits, and zero-day attacks. The company's Cloud Security Platform leverages this Isolation Core to enable secure internet access and browsing without compromising user experience.

Only safe, non-executable content is rendered on users' devices, providing a seamless browsing experience while mitigating risks. The platform is designed to help organizations embrace cloud transformations securely without sacrificing data visibility, control, or user experience.
In March 2019, Menlo Security partnered with By Light to deliver a cloud-based internet isolation (CBII) solution for the Defense Information Systems Agency (DISA), protecting over 3.5 million users worldwide across the US Department of Defense and its branches. This solution leverages Menlo's Cloud Platform and Isolation Core to secure internet access for defense officials deployed globally.
In January 2023, Menlo Security's Cloud Security Platform powered by its Isolation Core received Authorization to Operate (ATO) at the moderate level under the Federal Risk and Authorization Management Program (FedRAMP).

It leverages machine learning to build behavioral models for all employees and automatically detect security threats such as business email compromise, data exfiltration, phishing, and accidental data loss. Tessian's platform, referred to as "human layer security," notifies employees of these issues to help improve individual security behaviors.
