Secure Outbound Web Gateway for a Large UK Government Department

A new Secure Outbound Web Gateway was developed and implemented for the second-largest UK Government department, enabling secure and efficient web access for 100,000 users. The service included both Secure Access Service Edge (SASE) and on-premise deployments, integrating advanced security technologies to replace a legacy third-party solution.

The Secure Outbound Web Gateway was designed to provide secure, policy-driven web access for the department’s extensive user base. By integrating enterprise-class forward proxy appliances with Next Generation Firewall technologies, the service ensured robust security, seamless user experience, and enhanced compliance with Government standards.

The Challenge

The department needed to migrate 100,000 users from a legacy third-party service to a modern, secure web gateway solution. The new service had to deliver enhanced security features, such as granular user authentication and advanced content filtering, while maintaining resilience and scalability to meet the demands of a large Government organisation.

The Solution

The Secure Outbound Web Gateway was delivered as a hybrid solution, combining SASE and on-premise deployments. It included Kerberos authentication for seamless user identity management, URL filtering with customisable user policies, intrusion prevention, and advanced threat detection capabilities. The solution integrated with the department’s existing directory services, protective monitoring systems, and implemented HTTP header insertion for enhanced control over web traffic.
