Log file changes in Sophos UTM 9.3

But the most exciting feature in UTM 9.3 from Fastvue's perspective is not even mentioned in the list of features or bug fixes. It is the addition of two new fields to the web filtering log files; Referer and User Agent (ua). Most exciting is the addition of the Referer field.

Why is logging referrer so exciting?

With the addition of the referer field, Fastvue Sophos Reporter will be able to provide significantly more useful web usage reports.

You may have noticed in your existing web reports, whether that is in Fastvue Sophos Reporter, the on-box reports, or even in the new Sophos iView, that the list of websites presented do not identify what websites were actually visited. Your reports show excessive usage to sites such as,, and a long list of other 'junky' looking websites.

This is because when you visit a website, your browser may access dozens of other domains to retrieve images, adverts, scripts, social sharing buttons, perform visitor tracking, A/B testing, page optimization and so on. All of these hits to other domains end up in your Sophos UTM web filtering logs and are consequently shown in your web reports.

Introducing Fastvue Site Clean

With the addition of referer URL in the web filtering log files, Fastvue Sophos Reporter is able to more accurately identify the original website that a web resource came from.

This is part of our larger Fastvue Site Clean feature, which also integrates a frequently updated web service that identifies common CDNs, advertising and other web widgets that may still fall through the referrer chain.

Here's a quick animation demonstrating Fastvue Site Clean in action.

Site Cleaning in Fastvue Sophos Reporter


As you can see, the Site sections in Fastvue Sophos Reporter's Overview Reports will include a 'Cleaned' list of sites, as well as the normal 'logged' list of sites, and provide the option to view both of these side by side.

Allowing simple access to both the cleaned sites and the logged sites, makes troubleshooting why a site is blocked, allowed or categorized a certain way much easier.

For example, if an image on was blocked because it came from an advertising domain, you want to know that the advertising domain was blocked, not But is also very useful to know that the image was viewed while looking at

The Fastvue Site Clean feature is part of Fastvue's ongoing commitment to improve the usefulness of web reporting as a tool for managing online productivity, bandwidth problems and giving you the additional visibility you need to efficiently secure your network.
