Local Web Filtering

Local web filtering allows you to define custom URL categories, which can be included in blocklists and allowlists that are evaluated on the SRX Series Firewall. All URLs for each category in a blocklist are denied, while all URLs for each category in a allowlist are permitted. With local Web filtering, a firewall intercepts every HTTP and HTTPS request in a TCP connection and extracts the URL. A decision is made by the device after it looks up a URL to determine whether it is in the allowlist or blocklist based on its user-defined category.

Starting in Junos OS 26.2, local web filtering also includes support for HTTP/2.
