The new ZTNA gateway capability will be enabled for early access as part of Sophos ZTNA in Sophos Central in September 2023.
- New SSD firmware: Updated SSD firmware is available for select SSD models within the following 1U appliances: XGS 2100, 2300, 3100, 3300, and 4300
The new firmware optimizes performance and reliability.
Other enhancements
- Akamai SIA integration: With the Akamai Secure Internet Access (SIA) integration you can on-ramp traffic from Sophos Firewall to Akamai SIA SSE (Security Service Edge) using redundant and resilient SD-WAN over route-based IPsec VPN tunnels. For configuration details, go to Connect Akamai SIA and Sophos Firewall.
- Cloudflare Magic WAN integration: You can on-ramp traffic from Sophos Firewall to CloudFlare Magic WAN using redundant and resilient SD-WAN over route-based IPsec VPN or GRE tunnels. For configuration details, go to Connect Cloudflare Magic WAN and Sophos Firewall.
Version 19.5 MR2 Build 624
Released on May 09, 2023
New features
This page describes the new features introduced. For details, see the Sophos Firewall help.
Important security and hardening enhancements
The release implements two security enhancements that help harden your firewall and follow the industry best practices to protect your firewall from attacks.
These changes impact access to the web admin console and user portal from the WAN zone.
Web admin console access from specific WAN IP addresses:
- We strongly recommend turning off web admin console access from all WAN sources (the entire internet) to reduce the potential for a brute force or reconnaissance attack.
- For remote management of your firewalls, we recommend using Sophos Central. It's free for customers.
- If you must provide access to the web admin console from WAN, go to Administration > Device access, add a local service ACL exception rule, allowing specific IP addresses and networks.
- Web admin console will no longer be available from all WAN sources. So, you won't be able to select WAN under HTTPS on Administration > Device access.
Note Existing deployments aren't impacted. If you've already turned on web admin console access from all WAN sources, the functionality continues to work after you upgrade to SFOS 19.5 MR2.

Sophos Firewall release notesSophos Known Issues listXG Firewall release notesSophos Firewall release notesUnused WAN access to web admin console and user portal:
- Web admin console and user portal access from all WAN sources will be turned off if there aren't any successful sign-ins from the WAN zone for 90 consecutive days. This applies to all deployments.
- Access given to specific WAN IP addresses and networks through a Local service ACL exception rule isn't impacted. These sources will continue to have access even if there are no sign-ins.
This has been done to prevent instances where the access was turned on but remains unused, leaving the firewall potentially exposed on the internet to brute force and reconnaissance attacks.
Note If you've already turned it on before migration and are actively using it, the functionality will continue to work.
For details, see Best practices for securing your firewall.
IPsec how-to article list accessible from web admin console
Routing and NAT configurations for IPsec: A how-to article list is directly linked from Site-to-site VPN > IPsec to help with IPsec configurations that require routing and NAT. The list includes articles that address use cases, such as system-generated DHCP relay and authentication traffic and traffic to a host through an existing IPsec tunnel.
Other enhancements
The version offers the following enhancements:
Dynamic routing: The firewall now supports up to 4000 multicast groups providing additional scalability in dynamic routing deployments. This eliminates issues related to dynamic routes being unable to join multicast groups.
SD-RED: A new banner on the Wireless pages highlights the approaching End-of-Life (EOL) date for legacy RED 15, 15w, and RED 50 devices. EOL is on August 31, 2023.
You must upgrade your RED devices to the latest models, which offer higher performance and improved connectivity.

Sophos Firewall release notesXstream architecture
- SD-WAN:
- SD-WAN load-balancing to maximize bandwidth use across multiple links. You can select load balancing as the routing strategy in SD-WAN profiles. You can use round-robin and session persistence based on source and destination IP addresses and connection criteria with gateway weights and SLAs. Ensures routing of application traffic across multiple links, including MPLS, WAN, VPN, and RED. See the help for Load balancing using SD-WAN profiles.
- Real-time monitoring and logging with enhanced gateway performance diagnostics for SD-WAN profiles. Shows link performance with total connections and data transfer count. You can also reset the counts for troubleshooting. See the help for SD-WAN performance diagnostics.
- IPsec VPN: Increased the maximum supported concurrent tunnels from 4,650 to 10,000. See the knowledge base article Supported VPN tunnels on SFOS 18.5, 19, and 19.5.
High availability
- Cluster and device identification:
- Added customizable node names to easily identify HA devices. The name is shown in the browser tab, drop-down widget, CLI, and notifications, allowing you to always identify the device.
- Enhanced HA status panel with information about node names, licensing source, initial primary, current role and status, and status change time for troubleshooting.
- Ability to set the HA cluster ID.
- Clarifies which device is the primary and which the auxiliary plus their license requirements.
- Persistent banner on the auxiliary device to easily identify the device.
- HA widget moved to the admin drop-down on the upper-right making it always available for quick access. Shows the node names, a quick view of the cluster health, and the important cluster information.
- Node name, device role, and enhanced HA information on the CLI. Shows the device role in the hash prompt for easy troubleshooting.
- Redundant HA links:
- Support for up to four interfaces for the dedicated HA link. You can configure the redundant links in QuickHA and interactive modes.
- Automatically creates a LAG interface for multiple dedicated HA links selected in QuickHA mode.
- Supports LAG and VLAN interfaces for the dedicated HA link.
- Supports unbound interfaces as monitored ports if you've configured VLAN on them.
- Clearer selection for the preferred primary device.
See the video for Sophos Firewall 19.5: High availability enhancements.
Dynamic routing
- OSPFv3: Supports OSPFv3 protocol, enabling dynamic routing for IPv6 traffic.
- Better routing decisions: OSPF and OSPFv3 use the configured interface speed, selecting higher-speed interfaces for routing.
- BGP: Automatic router ID selection for BGP allows dynamic updates to the router ID.
- Logs: Provides logs related to adjacency information for BGP, OSPF, and OSPFv3. See the help for BGP and OSPF commands.
- Other enhancements are as follows:
- Integrated a new dynamic routing engine for stable and future-ready capability.
- Fully interoperable with other vendors.
Static routes
Allows you to configure administrative distance and metric for IPv4 static routes. See the help for Static route enhancements.
Important changes in routing behavior
We introduced a new routing engine, which enables the firewall to monitor the interface link status and network configuration. Changes from the earlier behavior are as follows:
- BGP, OSPF, RIP configurations, by default, prevent network and route distribution to the peer if the interface link status is down. To change this default for only BGP, run the following command on the BGP CLI console: no bgp network import-check
- BGP configurations, by default, prevent network and route distribution to the peer if SFOS and BGP network have a non-matching subnet. To change the default, run the following command on the BGP CLI console: no bgp network import-check
- Zebra advanced shell CLI is NOT available due to the new dynamic routing engine. Static route configuration through the Zebra advanced shell CLI is NOT possible in v19.5 GA. You can add the same configuration on the SFOS web admin console on Routing > Static routes.
If you're upgrading or restoring the backup from an earlier version, the changes in behavior may bring network disruption. So, in some cases, the firewall won't allow you to upgrade to SFOS 19.5 GA. See the knowledge base article Upgrade to 19.5 GA blocked for specific routing configurations.
PKI acceleration for inspected TLS flows
The DPI engine offloads PKI processing for X.509 certificate re-signing for inspected TLS flows to the crypto hardware on the Xstream Flow Processor. PKI offloading delivers higher overall performance with SSL/TLS decryption in the following XGS Series appliances:
- 1UL (4300, 4500)
- 2U (5500, 6500)
See the help for information on Architecture for offloading.
Quality of life enhancements
The version offers the following enhancements:
- Azure AD SSO: Supports Azure AD SSO configuration for signing in to the web admin console. See the video for Sophos Firewall 19.5: Azure AD SSO.
- Interfaces:
- Interface speed: Detects the recommended link settings automatically. Supports advanced port configurations for high-speed interfaces, including FEC (Forward Error Correction) for high-speed 40G interface on XGS 5500 and 6500 appliances.
- Interface breakout: Supports the breakout of 40G interfaces into 2 or 4 x 10G interfaces through DAC or fiber breakout cables.
- RED unlock code: The RED provisioning server sends the unlock code to the email address specified on System services > RED when you add a RED device or delete it from the firewall. See the knowledgebase article Pop-up message and email for the RED unlock code.
- Search: Search capability by name, type, and value for the default and custom objects for Hosts and services. See the video for Sophos Firewall 19.5: Search enhancements.
- Log storage: Enhanced .log file storage for better troubleshooting with configurable rotation count and archiving, along with timestamp and size changes, for single or multiple log files.
Other changes
The "Always cache Sophos endpoint updates" setting on Web > General settings > Web content caching has been removed from the SFOS 19.5 GA release. Enhancements to the security and integrity of Endpoint update delivery have made this feature ineffective.

Upgrading firmware and restoring backups
Upgrading firmware
Information about 19.5.x is as follows:
- The version is available on all form factors.
- The version isn't FIPS-compliant. See Firmware upgrades from FIPS-compliant versions.
Important change to consider if you're migrating from 18.5 to 19.5.x
Remote access SSL VPN IP lease range: After you upgrade from 18.5 versions to 19.5.x, traffic may not flow through your remote access SSL VPN connections if you've added a custom host (for example, IP address range, list, or network for the leased IP addresses) to the corresponding firewall rule.
Go to the firewall rule, and select the system host ##ALL_SSLVPN_RW (and ##ALL_SSLVPN_RW6 if required) instead. See SSL VPN IPv4 lease range changes in SFOS 19.5.x.
Note: The above requirement does not apply if you're migrating from 19.0 or later firmware to 19.5.x.
Versions you can upgrade from
We strongly recommend that you migrate only to the approved versions in the following table. If you try to migrate to other versions, Sophos Firewall shows an alert asking you to confirm the migration before it restarts. If you confirm the migration, Sophos Firewall restarts with the factory configuration, and you lose your current configuration.
See how to upgrade.
| Upgrade from | Upgrade to 19.5 (all form factors) | ||||
|---|---|---|---|---|---|
| MR4 Build 718 | MR3 Build 652 | MR2 Build 624 | MR1 Build 278 | GA Build 197 | |
| 19.5 MR3 Build 652 | |||||
| 19.5 MR2 Build 624 | |||||
| 19.5 MR1 Build 278 | |||||
| 19.5 GA Build 197 | |||||
| 19.0 MR3 | |||||
| 19.0 MR2 | |||||
Sophos Central: You can schedule firmware upgrades from Sophos Central for firewalls using 18.0 MR3 and later.
Previously restored Cyberoam backup: If your appliance is using a configuration previously restored from a Cyberoam backup, the firewall allows you to upgrade to version 19.5.x only if you've regenerated the appliance certificate at least once on SFOS. (The appliance certificate generated on Cyberoam devices uses a weak signature algorithm (MD5). SFOS 19.5.x doesn't support appliance certificates with this algorithm.)
Static route configurations through Zebra advanced shell: We introduced a new routing engine, which enables the firewall to monitor the interface link status and network configuration. This is a change from the earlier behavior. If you're upgrading or restoring the backup from 19.0.x and earlier versions, static routes configured through the Zebra advanced shell CLI commands won't migrate to 19.5.x. So, in some cases, the firewall won't allow you to upgrade to SFOS 19.5.x. For details, see the knowledge base article Upgrade to 19.5 GA blocked for specific routing configurations.
Restoring backups
You can restore backups from any supported earlier version to 19.5.x.
To take a backup and restore the configuration between XG Series and XGS Series appliances, see Backup-restore compatibility check.
Supported platforms
Version 19.5
Sophos Firewall OS versions 19.5.x are available on all form factors as follows:
- XGS Series firewalls
- XG Series firewalls
- SG Series firewalls
- Virtual and software appliances
- Cloud platforms
For more information about the supported firmware versions, licenses, and migration, see Sophos Firewall: Licensing guide.
Minimum RAM
19.5.x versions require a minimum of 4 GB RAM. So, you can't upgrade the following models to these versions:
- XG 85, XG 85w, XG 105, and XG 105w
- SG 105, SG 105w
Supported firmware versions
19.5.x versions support the following firmware versions:
- Wi-Fi firmware 11.0.021 and earlier
- RED firmware 3.0.009 and earlier
- Sophos Connect 2.3 MR-1 and earlier
