Sophos XG makes it easy to expose internal services to the public internet using the Server Access Assistant (DNAT) wizard. However, this does generate a lot of configuration that is not strictly required. By knowing your environment, some basic theory, and what is and is not required, you can configure clean concise DNAT rules. This article uses the example of exposing a Plex server on the public internet to understand Sophos XG's DNAT Rules and how to optimize them.
This article outlines how you can use Sophos XG to block searches and URLs that contain specific keywords. This is can be useful in preventing school students from wasting time searching for mobile phone wallpapers and/or looking for 'VPNs' that could potentially result in students or employees getting around your Sophos rules and policies altogether!
Decrypting TLS 1.3 is only available with Sophos XG's new XStream DPI engine. Unfortunately, some features are not supported with the XStream DPI engine such as SafeSearch enforcement and YouTube restrictions. Thankfully you can deploy a combination of Web Proxy and DPI rules to get the best of both methods. This article describes how.
With many people now working from home due to COVID-19, reporting on Sophos XG's VPN activity is top of mind for many overstretched IT teams right now. To help, we've made some additions to Fastvue Sophos Reporter to provide better visibility into Sophos XG's VPN connections and ensure your remote infrastructure is holding up. With Fastvue Sophos Reporter's new VPN Dashboard and VPN Report, you can monitor the number of active sessions throughout the day to help plan for extra capacity, or use the reports to find who has not connected recently. You can also easily see when most people connect and disconnect, and proactively respond to unexpected disconnections or excessive invalid login attempts.
Fastvue was invited as a guest presenter in a recent webinar hosted by Sophos to help demonstrate how Fastvue Sophos Reporter together with the Sophos XG platform can provide schools with everything they need to safeguard and detect students at risk of self-harm, extremism/radicalization, and anti-social/unacceptable online behavior.

Sophos UTM tcpdump information can be very useful in troubleshooting connectivity issues. In this article, I will show you how to use the tcpdump command on Sohpos UTM to verify if syslog packets are leaving your Sophos UTM appliance.
When you have an active-passive Sophos UTM cluster, the configuration is synchronized between the nodes, but if the Master fails, it may not sync all the log data to the Slave node. From the WebUI, there is no method to view the files on the Slave device, yet those log files can contain information about the cause of the failure. This guide takes you through how to retrieve log files from a Sophos UTM cluster slave node and copy the file(s) to your local machine for analysis.

You can use custom categories not only for recategorizing websites in Sophos XG, but also for allowing or denying access to specific sites for certain users. They can also be used to reclassify the browsing 'productivity' for certain users when viewing Internet usage reports in Fastvue Sophos Reporter. For example, you can use them to classify lingerie sites as 'productive' for people in a retail lingerie department or to classify social media sites as 'productive' for people in the marketing department. There are a couple of "gotchas" in doing this, and I will explain how to avoid them while taking you through the process.
When configuring a Site-to-Site VPN on your Sophos SG or Sopho XG, you are presented with an option to select either TCP or UDP as the transport protocol. The configuration page hints that UDP provides better performance, so I thought it would be interesting to test the SSL VPN performance over both UDP and TCP protocols and find out which one is faster!

Sophos XG Firewall supports these four Dynamic DNS providers, but it also includes a fifth provider simply called Sophos, and the great news is it's free! This article takes you through configuring Sophos XG's free Dynamic DNS service.
I just happened to have an ageing Sophos UTM SG115 in our spare parts / swap out stock and thought I'd see if it could be repurposed (or rather re-imagined) as a Virtual Server running multiple virtual devices. Wouldn't it be cool to have Sophos UTM and Sophos SUM running on the same box? Let's give it a go!
This article describes how to use Fastvue Sophos Reporter to report on machines potentially infected with WannaCry Ransomware on your network. The first and second variations of WannaCry ransomware access specific domains before the installation phase. You can therefore report on all machines that have accessed these domains to help identify potentially infected machines.
The WannaCry Ransomware infection is currently causing havoc around the globe. Fortunately there are security patches available from Microsoft that fix the underlying security hole in SMB that the ransomware exploits. However it is a good idea to keep an eye on any machines on your network that are or were infected. With Fastvue Sophos Reporter, you can create a simple alert to receive instant notifications when machines on your network make requests to the domains that WannaCry accesses before installing.
We're pleased to announce that Fastvue Sophos Reporter now supports Sophos XG, providing the same great web usage reporting features for Sophos XG networks that Sophos UTM (SG) users have [...]

Since Google made the decision to implement HTTPS across all their web properties (including YouTube), you can report that someone has been to youtube.com, but not what videos they were watching. Likewise, you can report that someone has visited google.com, but not what they searched for. Fortunately, many Next Gen Firewalls, UTMs and Secure Web Gateways have a HTTPS Inspection feature that gets around this problem.
