Active Threat Response
Sophos Firewall supports a variety of Sophos and third-party threat feeds that provide actionable threat intelligence. If a threat is detected from any of these feeds, the firewall will automatically respond by blocking that device and initiating an automated cross-product Synchronized Security response.
Synchronized Security prevents lateral movement
Sophos Firewall is unique in continuously communicating and sharing information with other Sophos products to automatically respond to threats, coordinating with Sophos Endpoint, Sophos Workspace Protection, and Sophos Email to isolate attacks and prevent lateral movement until they are cleaned up.

Frequently asked questions
A traditional firewall controls traffic based on IP addresses, ports, and protocols. A next-generation firewall (NGFW) goes further by recognizing applications and users, inspecting encrypted traffic, and blocking advanced threats with integrated intrusion prevention and deep packet inspection. NGFWs provide stronger protection for modern, cloud-connected environments.
A firewall is essential, but it is not enough on its own. Modern environments include cloud services, remote users, encrypted traffic, and connected devices that expand the attack surface. Firewalls work best as part of a layered security strategy that includes endpoint protection, identity controls, monitoring, and threat response.
Yes. Cloud providers secure their infrastructure, but you are responsible for protecting your workloads, users, and configurations. A cloud-capable firewall helps enforce consistent security policies, control traffic between environments, and extend protection across on-prem, cloud, and hybrid networks — all from centralized management.
Modern firewalls provide visibility into users, applications, and encrypted traffic. They log activity, enforce granular policies, and integrate with centralized management platforms. This gives IT teams clearer insight into network activity and helps them respond faster to potential threats.
Firewalls secure connections between remote users, branch offices, and cloud applications. They can enforce policies consistently across locations, support VPN or Zero Trust Network Access (ZTNA), and inspect traffic to prevent threats from spreading across distributed environments.
Focus on three areas: security effectiveness, performance with protections enabled, and ease of management. Look for strong threat prevention, encrypted traffic inspection, centralized policy management, and the ability to scale across on-prem, cloud, and hybrid environments.
In Zero Trust and Secure Access Service Edge (SASE) models, firewalls act as secure control points that enforce least-privilege access and segmentation. They work alongside cloud-delivered security services to extend protection closer to users and applications while maintaining consistent policy enforcement.
- Secure by Design is a software development philosophy that treats security as a foundational requirement rather than an afterthought. Instead of building a product first and bolting on security fixes later, Secure by Design demands that security considerations are embedded into every stage of the development lifecycle — from architecture and design through coding, testing, deployment, and maintenance.
In an AI‑accelerated era, Secure by Design is no longer optional - it’s essential. This shift changes both how vulnerabilities are discovered and how organizations must respond in three fundamental ways:
- Speed: Vulnerabilities are discovered at machine speed, so firewalls must reduce exposure by eliminating entire classes of vulnerabilities.
- Scale: The volume of vulnerabilities discovered is unprecedented, so firewalls must automate patching to reduce the window of exposure.
- Scope: AI lowers the barrier to entry for attackers, so firewalls must be actively monitored as a security asset—not treated as a black box.
