Configure URL Reputation Service

Published April 5, 2023 | Last modified November 5, 2026

Objective

This guide provides instructions on how to enable the URL Reputation Service from within F5® Distributed Cloud Console (Console). The URL Reputation Service enables you to classify a URL based on a category or a score. After the URL is classified based on a risk, that URL can be denied or allowed based on your forward proxy policy configuration.

For more information, see HTTP Connect and Forward Proxy Policies documents.

Prerequisites

The following prerequisites apply:

Configuration

You can enable URL reputation classification using a basic method (URL categories) or a more advanced method (label selectors with URL categories and URL scores).

Basic method: Using single or multiple URL categories.

Each request received by your proxy server will be categorized using the following categories:

  • Dynamically Generated Content
  • Parked Domains
  • Alcohol and Tobacco
  • Private IP Addresses
  • Image and Video Search
  • Fashion and Beauty
  • Recreation and Hobbies

Advanced method: Using a label selector with two label options: reputation.ves.io/url-trustscore and reputation.ves.io/url-category.

You can use one or the other, or you can use both labels together in expressions. The lower the score, the higher the risk is for that particular URL. Each URL request received by your proxy server will be categorized on risk levels using a scoring system.

This table provides the score and corresponding score levels:

Score RangeScoreRisk
1-50LowHigh
51-80MediumMedium
81-100HighLow

 

The instructions provided in this guide show both methods for configuring your forward proxy policy to classify URLs (to deny) and assumes you are using an existing proxy server.

Step 6: Verify the operation.

After you configure the forward proxy policy for your proxy server, send a test request from a client IP address. If there is no URL category match for a URL, the request will be allowed. If the URL category matches, then the request will be denied.

Deny Malicious URLs Using Label Selectors

This forward proxy policy feature blocks URLs based on URL scores. Note that the lower the score attached to a particular URL, the higher the malicious risk with that URL.

Step 1: Navigate to forward proxy policies in Console.
