A Secure Web Gateway (SWG) is a solution that filters unwanted software/malware from user-initiated web/internet traffic and enforces corporate and regulatory policy compliance. SWGs can block malware, malicious websites, prevent data exfiltration, and access to unauthorized sites or web apps. They provide enhanced threat detection, reduced attack surface, greater network visibility, improved compliance, and prevention of data loss. SWGs work by inspecting all inbound and outbound internet traffic, blocking outgoing access to unsecure websites, and comparing incoming traffic against deny lists of known malware and malicious websites. Advanced SWGs incorporate artificial intelligence, machine learning, and other heuristics to detect patterns from emerging threats. Cloud-based SWG providers use software-as-a-service business models and large point-of-presence networks to address performance issues. Secure web gateways are distinct from IPsec virtual private network (VPN) gateways and can complement Zero Trust network architectures. Twingate's Zero Trust solution creates secure, direct connections between users and protected resources, simplifying the migration to Zero Trust.
