Engineered for Performance
Sophos Firewall protects increasingly encrypted, application-rich, and AI-enabled traffic with an Xstream Architecture designed to accelerate eligible traffic and preserve capacity for deeper inspection.
Connected for Coordinated Response
Sophos Fusion connects network and other security control points so shared context can drive coordinated response and enforcement across the security environment.
Secure by Design architecture
Sophos makes security a built-in foundation, not an add-on, with secure defaults, hardened architecture, health checks, remote integrity monitoring, and over-the-air hotfixes.
WHY SOPHOS
One Connected Defense for the AI Era
Sophos Firewall puts the network at the heart of the Sophos AI-Native Cybersecurity Defense System, combining high-performance protection, Secure by Design resilience, network visibility, and coordinated enforcement to strengthen defenses across the organization.
- Sophos Fusion connects network intelligence with Sophos and supported third-party control points, bringing more security context together for detection and response.
- Security Heartbeat and Active Threat Response turn detections and threat intelligence into coordinated action across firewalls, endpoints, switches, access points, XDR, and MDR.
- Sophos Firewall strengthens the network control point itself with secure defaults, hardened and containerized architecture, health checks, remote integrity monitoring, and over-the-air hotfixes that do not require a reboot.
Security for the AI Era
See how Sophos and WatchGuard compare as networks become more encrypted, distributed, application-rich, and increasingly important to cybersecurity detection and response.
| Capability | Sophos MDR | WatchGuard |
|---|---|---|
| AI-ERA NETWORK PERFORMANCE | Xstream Architecture Sophos Firewall accelerates eligible traffic while preserving capacity for deeper inspection of encrypted, application-rich, and AI-enabled traffic. |
WatchGuard provides traffic acceleration but lacks the same Xstream Architecture approach, which combines acceleration with preserved capacity for deeper security inspection. |
| AI-NATIVE CYBER DEFENSE SYSTEM | Sophos Fusion A single, open cyber defense system where control points, agentic AI, threat intelligence, and human experts operate as one. More than 500 Sophos and third-party integrations extend visibility and coordinated response across existing investments. |
ThreatSync delivers correlated detection and response across the WatchGuard security portfolio, but its scope is centred on XDR rather than a broader AI-native cyber defense system. |
| SECURE BY DESIGN | Protection built in, not added on Sophos Firewall combines secure defaults, hardened and containerized architecture, health checks, remote integrity monitoring, and over-the-air hotfixes that do not require a reboot. |
Fireware security updates require firmware upgrades and reboots, introducing maintenance windows and, for some upgrades, potential service interruption |
| CENTRAL MANAGEMENT | Unified management through Sophos Fusion Sophos Fusion provides a consistent cloud-native experience for managing and reporting across firewalls, endpoint, email, wireless, switches, XDR, MDR, and more |
WatchGuard management and reporting can span Fireware Web UI, WatchGuard System Manager, WatchGuard Cloud, Dimension, and WatchGuard Cloud Visibility, with capabilities varying by tool and deployment model. |
| CONNECTED DEFENSE | From network signal to coordinated action Synchronized Security and Active Threat Response share context and coordinate isolation and blocking across endpoints, firewalls, switches, access points, XDR, and MDR, while Sophos Fusion extends connected defense across more control points. |
ThreatSync coordinates detection and response across supported WatchGuard products, but offers a narrower enforcement scope across network and security control points. |
| NETWORK VISIBILITY AND DETECTION | NDR integrated with the firewall NDR Essentials integrates directly with Sophos Firewall, using cloud-hosted AI and machine learning to analyze network activity without impacting firewall performance. It is included at no extra charge with Xstream Protection on supported XGS appliances. |
WatchGuard NDR for Firebox requires a separate license for each compatible Firebox. Broader NDR capabilities, including collection agents and cloud integrations, require WatchGuard NDR or Total NDR licensing. |
| SD-WAN ORCHESTRATION | Centralized SD-WAN orchestration Sophos Fusion centrally orchestrates SD-WAN across multiple firewalls, automating VPN tunnel creation and, when selected, the required firewall rules. Performance-based routing and zero-impact failover help maintain application availability. |
WatchGuard supports central SD-WAN templates, but the matching SD-WAN action must already exist on each Firebox. If it does not, the template applies the policy without the SD-WAN action, creating inconsistent routing. |
