The purpose of this document is to provide customers of Proofpoint’s Browser, Email and TAP URL Isolation products (collectively, "Isolation") with the information necessary to assess how the product can support and enhance their data privacy strategies.
Isolation – Product Statement
Isolation runs on the cloud-native Information and Cloud Security Platform ("Platform") and is a secure cloud-based container that helps protect organizations from URL and web-based attacks. It solves the problem of having to choose between a too-restrictive ’block” policy and a too-risky "allow" policy by providing a third option that allows users to safely click and view high-risk sites in isolation.
Isolation sanitizes web pages by stripping them of any active content then re-renders those pages on the local browser using static/safe content. When in an isolated browsing session, the user can see and interact with the page as normal; however, the site cannot escalate privileges, gain root access, execute malicious code, make persistent unauthorized system changes, and alter critical system files. Isolation protects companies from malware infections, phishing threats, credential theft, email fraud, and data loss.
Isolation has an anonymous usage feature that, when enabled, hashes the email address of the user before it is stored in an encrypted manner. If the feature is not enabled, the email address of the user is stored at registration in an unhashed form. Anonymous usage is not supported in the URL Isolation integration with TAP.
