Sophos Firewall v20 is here, bringing dynamic threat feeds, advanced networking capabilities, and synchronized security improvements. Learn how the latest update enhances threat detection, automates responses, and boosts network performance.

We are extremely pleased to announce that Sophos Firewall v20 is now available. This latest release includes an innovative new active threat response capability, several networking enhancements, added support for securing your remote workforce, and many of your top-requested features.

Sophos Firewall v20 is a free upgrade for all licensed Sophos Firewall customers.

Watch the video below for an overview of what’s new, download the What’s New PDF, or read on for the full details and deep-dive demo videos.

Active Threat Response

Extending Synchronized Security to MDR and XDR provides a direct feed for security analysts to share active threat information with the firewall, enabling it to automatically respond to active threats without creating any firewall rules.

Dynamic Threat Feeds introduces a new threat feed API framework that is easily extensible. It enables threat intelligence to be shared by the Sophos X-Ops team, other Sophos products like MDR and XDR, and ultimately third-party threat feeds in the future.

Synchronized Security extends the same Red Heartbeat, automated response that Sophos Firewall has always had and applies it to MDR/XDR identified threats. This ensures compromised hosts are not able to move laterally or communicate out, while details including host, user, and process are readily available for follow-up. Synchronized Security has also been enhanced with added scalability and reduced false missing heartbeats for devices that are in sleep or hibernation states.

Remote worker protection and SASE

ZTNA gateway integration makes ZTNA deployments even easier by integrating a ZTNA gateway directly into the firewall. This means any organization that needs to provide remote access to applications hosted behind the firewall doesn’t need to deploy a separate gateway on a VM. They can simply take advantage of the gateway integrated into their firewall. When combined with our single-agent deployment on the remote device, ZTNA couldn’t possibly get any easier. It’s literally zero-touch zero trust.

Third-party SD-WAN integration makes it easy to onramp SD-WAN traffic onto Cloudflare, Akami, or Azure backbone networks to take advantage of their enormous infrastructure, reach, and networking and security services.

Sophos DNS Protection is our new cloud-delivered web security service that will be available separately in early access very soon. It provides a new Sophos-hosted domain name resolution service (DNS) with compliance and security features that are fully supported by Sophos Firewall. This service provides an added layer of web protection, preventing access to known compromised or malicious domains across all ports, protocols, or applications – both unencrypted and encrypted. More news on this new service is coming soon.

Network scalability and resiliency enhancements

A new VPN portal provides a containerized, hardened self-service portal for end users to download VPN clients and configurations, auto-provisioning, and clientless VPN bookmarks.

IPsec enhancements include seamless HA failover, tunnel status monitoring via SNMP, unique PSK support for the same local and remote gateway connections, and DH Group 27-30/RFC6954 support.

SSL VPN enhancements include FQDN (fully qualified domain name) host and group support for both remote access and site-to-site SSL VPN.

SD-WAN scalability triples SD-WAN gateway scalability to 3072 gateways and the number of SD-WAN profiles to 1024.

IPv6 enhancements include DHCP prefix delegation to seamlessly integrate with your ISP and new enhancements to the dynamic routing engine now support BGPv6 for improved IPv6 interoperability.

Watch a video overview of the VPN enhancements or the IPv6 BGPv6 and DHCPv6 capabilities.

Streamlined management

Interface enable/disable delivers a top-requested feature to easily disable or enable network interfaces on the firewall without losing any configuration.

Object reference lookup addresses another top-requested feature to find where a given host or service object is used in rules, policies, and routing.

Hi-res display support adds increased horizontal scalability to the management console to take advantage of high-resolution displays and reduce horizontal scrolling.

Auto-rollback on failed firmware updates reduces any disruption, including high-availability deployments.

Backup and restore now includes the option to restore a backup from a firewall with integrated Wi-Fi to a firewall without Wi-Fi.

Azure AD SSO for captive portal adds support for user authentication on the captive portal using their Azure AD credentials.

Azure group import and RBAC add support for a new import assistant for Azure AD groups and automatic promotion for role-based admin changes.

Watch videos covering the new management features and Azure AD capabilities.

Other enhancements

Web Application Firewall (WAF) enhancements include geo IP policy enforcement, custom cipher configuration, and TLS version settings, as well as improved security with HSTS enforcement and X-Content-Type-Options enforcement.

Azure Single Arm deployment support enables the choice of a smaller instance size to save on infrastructure costs and reduce network and operational complexity.
