Sophos Firewall OS – Important changes to the lifecycle policy

Sophos is constantly working to improve the security of its hardware and software. To provide the maximum and most efficient protection, we need to constantly update both hardware and software. Software updates are performed regularly and new features are added with each update.

In April 2021, Sophos introduced a new hardware series, which in terms of performance is again sufficient for the next few years. Upcoming software releases will be even better optimized for this new hardware. This is perhaps why Sophos is now making important changes to the Sophos Firewall OS (SFOS) software release lifecycle. As of July 31, 2021, the following versions are End of Life:

  • v17.5 MR13 and older
  • v18.0 MR3 and older

End of Sale means that the product can no longer be purchased from Sophos or verified resellers. End of Life, on the other hand, means that Sophos no longer supports this product. There will be no future releases for this product.

After July 31, 2021, any new SFOS release will automatically EOL the previous version. This is the new principle that Sophos has introduced.

If users continue to use the products that have reached End of Life, they can continue to use the features that were included in the last build before the EOL end was announced. However, this product does not offer all the new features that Sophos releases, and outdated hardware does not support new software in some cases.

On the following Sophos page you will find a list of hardware that is currently or will soon reach the end of its service life:

Sometimes you don’t really know which hardware revision you have in use. This web page from Sophos can help:
