E2guardian Filtering Proxy on Ubuntu 24.04

Overview

E2guardian is a web content filtering proxy that sits between users and the internet and applies policy to every request. It filters by domain, URL, file extension, MIME type and weighted phrase content, and returns a clear block page when a request is refused rather than failing silently. It runs standalone, connecting directly to origin sites, or chains to an existing proxy if one is already deployed. Every transaction is written to a structured access log, so outbound browsing is both governed and auditable, which is why it is widely used in schools, managed networks and regulated environments.

Common uses

• Filter and log outbound web traffic for a managed or education network
• Enforce an acceptable use policy with a clear block page for end users
• Provide an auditable egress path for regulated or restricted environments
