Secure Web Gateway (SWG) protects users against phishing, malware and other Internet-borne threats. Unlike traditional firewalls, Secure Web Gateways are focused on layer 7 web traffic inspection, both inbound and outbound. As web security solutions, they apply no protection to WAN traffic, which is left to the corporate Next Generation Firewalls. In recent years, Secure Web Gateways appeared as cloud services. The cloud instances enable secure web and cloud access from anywhere – including outside the office by mobile users. The traffic coverage and solution form factor remain the key distinctions between Secure Web Gateways and Next Generation Firewalls who often provide a very similar level of security capabilities.
A converged, cloud-based network security solution converges the capabilities of a Next Generation Firewall (WAN and Internet traffic inspection) and the extended coverage for mobile users of Secure Web Gateways.
A converged approach eliminates the need to maintain policies across multiple point solutions and the appliance life cycle.
