Sophos UTM Update v9.6 released

Sophos has released UTM version 9.600 We have listed all the new features that have made it into version 9.6.

Let's Encrypt Integration

An integration of Let's Encrypt on the UTM was desired by many. With version 9.6 the long wait seems to be over. The certificate can be created via the WAF and is automatically renewed.

Tip: If you have set up a DNAT for HTTP, you have to disable it on the interface where Let's Encrypt was configured. Country blocking can also interfere, so an exception should be created.

ATP: New Advanced Threat Protection Library

Advanced Threat Protection has received a new library and now offers even more protection and better performance.

RED: Unified RED Firmware

The RED 15 and RED 50 get a new firmware, which will include current drivers for 3G/4G USB sticks. This should improve the support of such 3G/4G sticks.

Sandstorm: Manual File Submission and Reports

An administrator will now be able to manually upload a file for execution in Sophos Sandstorm. This means that even files that were not received by email or web download can now be analyzed with Sophos Sandstorm. Sandstorm's reporting has also been improved to provide more detailed data over time.

SMTP Proxy: Enhancements

The SMTP proxy gets a support for the "Submission Port" and a configurable "Listen Address".

WAF: Error Page Customization

All error pages provided by the WAF can now be customized with custom designs. It is now also possible to provide your own corporate identity on all pages.

Sobering regarding IKEv2

IKEv2 has often been requested by the community. According to Sophos, integrating IKEv2 into UTM 9.6 was no longer sufficient. Seriously, don't expect IKEv2 to come for UTM! If we look at XG's roadmap, it's extremely full and this is clearly the main focus. The UTM Roadmap, on the other hand, is practically empty.

If you absolutely need IKEv2, we would recommend you to switch to the new operating system SFOS as soon as possible. If you have an SG Appliance, you won't even have to pay for the change and the license period will be taken over. If you need help with the migration, we will be happy to help you. As of today (23.11.2018) we haven't installed any UTM for one and a half years, only XGs. Our UTM know-how we only had to retrieve during the several migrations to SFOS.

Note: During the update, the UTM system is restarted and the configuration is updated. Note that a firmware update is also carried out on the connected REDs and access points.

Important: After the update to UTM 9.6, the old HTML template for content warning in the HTTP proxy no longer works correctly. Please download the updated templates , adapt them to your needs and upload them again to UTM.
