Following a really busy and profitable early entry program, the Sophos Firewall crew is happy to announce that v21.5 is now out there to all licensed Sophos companions and prospects.
This launch brings an industry-first innovation: integrating Community Detection and Response (NDR), which boosts energetic menace detection in your community.

An {industry} first innovation: NDR Necessities
Sophos is the primary to combine an NDR answer with a firewall, additional extending Sophos Firewall’s benefits with XDR and MDR use circumstances.
We’ve taken the novel method of implementing NDR within the Sophos Cloud to dump all evaluation processing from the firewall, eliminating any efficiency hit.
We’re calling this NDR Necessities, and the most effective half is, we’re enabling this for all XGS Sequence firewall prospects who’ve the Xstream Safety license bundle – at no further cost.
How NDR Necessities works
Sophos Firewall’s XGS Sequence captures meta information from TLS encrypted visitors and DNS queries and sends that data to NDR Necessities within the Sophos Cloud the place the info is analyzed utilizing a number of AI engines.
It could actually detect malicious encrypted payloads with out performing TLS decryption. This addresses an enormous blind spot in most organizations the place man-in-the-middle TLS inspection just isn’t getting used for efficiency, usability, or safety causes.
As well as, the NDR Necessities area era algorithm detects new and suspect domains generated by malware which can be usually a key indicator of compromise. In reality, in lots of circumstances, NDR Necessities can detect new C2 domains earlier than they’re even registered.
The meta information extraction is carried out by a brand new light-weight engine applied on the Xstream FastPath, and in consequence, one caveat with this new functionality is that it is just out there on XGS Sequence {hardware} firewalls. Digital, software program, and cloud firewalls could get this NDR Necessities integration functionality sooner or later, however not in v21.5.
Different enhancements and high requested options
Entra ID (Azure AD) single sign-on for distant entry VPN
One in all your high requested options makes distant entry VPN simpler for finish customers, enabling them to make use of their company community credentials with the Sophos Join shopper and the firewall VPN portal:
- Entra ID (Azure AD) single-sign on integration with Sophos Join and the VPN portal is now included in SFOS v21.5
- It offers cloud-native integration over the {industry} normal OAuth 2.0 and OpenID Join protocols for a seamless expertise
- Supported with Sophos Join shopper 2.4 (and later) on Microsoft Home windows
- Different VPN and scalability enhancements
Consumer interface and usefulness enhancements
Connection sorts have been renamed from “site-to-site” to “policy-based,” and tunnel interfaces have been renamed to “route-based” to make these extra intuitive.
- Improved IP lease pool validation: Throughout SSLVPN, IPsec, L2TP, and PPTP distant entry VPN to remove potential IP conflicts
- Strict profile enforcement: On IPsec profiles that exclude default values to make sure a profitable handshake, eliminating potential packet fragmentation and tunnels failing to ascertain correctly
- Route-based VPN scalability: Route-based VPN capability is doubled with assist for as much as 3,000 tunnels
- SD-RED scalability: Sophos Firewalls now assist as much as 1,000 site-to-site RED tunnels and as much as 650 SD-RED gadgets.
Sophos DNS Safety
Final 12 months, we launched our DNS Safety service and made it free for all Xstream Safety-licensed firewall prospects. With this launch, Sophos DNS Safety will get additional integration with Sophos Firewall.
- New Management Middle widget to point service standing
- New troubleshooting insights by way of logging and notifications
- New guided tutorial on the way to arrange Sophos DNS Safety simply
Streamlined administration and quality-of-life enhancements
As with each Sophos Firewall launch, this model contains a number of quality-of-life enhancements that make day-to-day administration simpler.
- Resizable desk columns: A protracted-requested function, many firewall standing and configuration screens now assist resizable column widths which can be retained in browser reminiscence for subsequent visits. Many screens akin to SD-WAN, NAT, SSL, Hosts and providers, and site-to-site VPN all profit from this new function.
- Prolonged free textual content search: SD-WAN routes now allow looking by route identify, ID, objects, and object values like IP addresses, domains, or different standards. Native ACL guidelines additionally now assist looking by object identify and worth, together with content-based search.
- Default configuration: By well-liked demand, the default firewall guidelines and rule group beforehand created when organising a brand new firewall have been eliminated, with solely the default community rule and MTA guidelines offered throughout preliminary setup. The default firewall rule group and the default gateway probing for customized gateways are each set to “None” by default.
- New font: The Sophos Firewall consumer interface now sports activities a brand new lighter, cleaner, sharper font for added readability and improved efficiency
Different enhancements
- Digital, software program, cloud licensing: In case you missed it, all Sophos Firewall digital, software program, and cloud licenses (BYOL) not have RAM limits. Licenses are actually strictly restricted by core depend and haven’t any RAM restrictions.
- Bigger file dimension restrict in WAF: Helps a configurable request (add) file dimension restrict for Internet Utility Firewall (WAF), which might now scan information as much as 1 GB
- Safe by design: We’re regularly enhancing the safety of Sophos Firewall, and on this launch are including real-time telemetry gathering to flag any sudden modifications to core OS information utilizing safe hash validation. It will allow our monitoring groups to proactively establish potential safety incidents early earlier than they will develop into an actual drawback.
- DHCP prefix delegation rest: Now helps /48 to /64 prefixes, enhancing interoperability with ISPs. Router commercials (RA) and the DHCPv6 server are additionally now enabled by default.
- Path MTU discovery: It will resolve TLS decryption errors because of the newest ML-KEM (Kyber) key change assist in browsers. The Sophos Firewall deep packet inspection engine will now routinely detect and regulate the MTU for every circulate, making certain optimum efficiency based mostly on particular community situations.
- NAT64 (IPv6 to IPv4 visitors): NAT64 is supported for IPv6 to IPv4 visitors in specific proxy mode. On this mode, IPv6-only shoppers can entry IPv4 web sites. The firewall additionally helps IPv4 upstream proxy for IPv6-only shoppers.
Methods to get v21.5
As with each firewall launch, Sophos Firewall v21.5 is a free improve for Sophos Firewall prospects with Enhanced or Enhanced Plus Assist and must be utilized to all supported firewall gadgets as quickly as potential. This launch not solely accommodates nice options and efficiency enhancements, but additionally necessary safety fixes.
Sophos Firewall v21.5 is a totally supported improve from any supported Sophos Firewall firmware model.
This firmware launch will observe our normal replace course of. The brand new v21.5 firmware will probably be step by step rolled out to all linked gadgets over the approaching weeks. A notification will seem in your native machine or Sophos Central administration console when the replace is on the market, permitting you to schedule the replace at your comfort.
You may both wait till the firmware replace notification seems in Sophos Central or your native machine console, or you possibly can manually obtain the newest Sophos Firewall firmware from Sophos Central at any time.
