Sophos Firewall OS v20 MR3 is Now Available

We launched Sophos Firewall v21.0 in October this year with new innovations and top requested features.

Many organizations have already upgraded, but for those that haven’t, now is the time! You will see the v21.0 update waiting for you in Sophos Central, or in the web admin console of the firewall as soon as you login.

If you are still continuing with v20, we’ve released a maintenance update for v20 with MR3. v20 MR3 brings important security, performance, and reliability fixes.

Issues Resolved in v20 MR3:

This maintenance release resolves 35+ important performance, reliability, stability and security fixes.

Enhancement related to synchronized security missing heartbeat:

Remove the missing heartbeat status of endpoints

• Endpoints that move to a missing heartbeat status in the firewall and then move out of the network continue to appear with this status on the control center and in reports. The missing heartbeat status can only change when they reconnect to the network.

• A new CLI command in v20 MR3 allows you to remove the missing heartbeat status for these endpoints.

Check out the v20 MR3 release notes for full details.

How to get the firmware and documentation

Sophos Firewall OS v20 MR3 is a free upgrade for all licensed Sophos Firewall customers and should be applied to all supported firewall devices as soon as possible to ensure that you have all the latest security, reliability, and performance fixes.

This firmware release will follow our standard update process. You can manually download SFOS v20 MR3 from Sophos Central and update anytime. Otherwise, it will be rolled out to all connected devices over the coming weeks. A notification will appear on your local device or Sophos Central management console when the update is available, allowing you to schedule the update at your convenience.

Sophos Firewall OS v20 MR3 is a fully supported upgrade from all previous versions of v20 and v19.5. Please refer to the Upgrade Information tab in the release notes for more details.

Full product documentation is available online and within the product.

Keep Your Firmware Up to Date

Sophos Firewall integrates an innovative Hotfix capability that enables us to push urgent and important patches out to the firewall “over the air” to address any new zero-day vulnerability or other critical issue that arises. This enables a rapid fix to be applied without requiring any downtime normally associated with a firmware upgrade and restart.  You get the benefit of important fixes being applied immediately without any manual effort on your part.

However, it’s super important to ensure your firewall firmware is kept up to date as non-urgent security fixes are often integrated into maintenance releases. Since all firmware updates are free for licensed Sophos Firewall customers, there’s no reason not to take advantage of all the great enhancements in every release.

Sincerely,

Sophos Firewall Product Team.
