ProductsSFOS v19.5Sophos Firewall

The latest Sophos Firewall release adds a boost in IPsec performance, new Xstream TLS FastPath acceleration, and powerful OSPFv3 routing. Plus, you’ll gain added resiliency and redundancy with SD-WAN load balancing. New high availability (HA) enhancements also provide easier management, plus there’s Azure AD integration and enhanced search capabilities.

We are pleased to announce that Sophos Firewall OS v19.5 is now released and generally available. This update to Sophos Firewall brings a number of exciting enhancements and top requested features.

What’s New:


Xstream SD-WAN:

  • SD-WAN Load Balancing builds on the powerful SD-WAN capabilities introduced in v19 to add load balancing across multiple SD-WAN links for added performance and redundancy.
  • IPsec VPN Capacity is also significantly increased enabling up to double the number of concurrent tunnels depending on your XGS Series model.
  • Dynamic Routing with OSPFv3 (IPv6) which has been one of our top requested features bringing enhanced routing, flexibility, security, and performance.


Xstream Protection and Performance:

  • Xstream FastPath Acceleration of TLS encrypted traffic takes advantage of the hardware crypto capabilities in the Xstream Flow Processor to accelerate TLS encrypted traffic flows on the FastPath on the XGS 4300, 4500, 5500, and 6500. This provides added performance headroom for traffic that requires deep-packet inspection.


High Availability:

  • Several Status, Visibility and Ease-of-Use Enhancements improve the operation of high availability (HA) configurations.
  • Redundant Link Support enables your high availability devices to be connected with multiple redundant HA links to add resiliency and reliability.


Quality of Life Enhancements:

  • Azure AD integration for SSO web console login offers an alternate and easier method of authentication.
  • Host and Service Object Search enables you to perform free text searches for host and service objects by name or value.
  • Enhanced .log file storage enables advanced troubleshooting.
  • Enhanced 40G Interface Support with auto-detection of advanced port configurations on XGS 5500 and 6500 models.

How to get the firmware, documentation, and training

As usual, Sophos Firewall OS v19.5 is a free upgrade for all licensed Sophos Firewall customers and should be applied to all supported firewall devices as soon as possible, as it not only contains great features and performance enhancements, but also important security fixes.
