SWG

Symantec Secure Web Gateway, which we acquired as ProxySG and Web Security Service (WSS) with Blue Coat Systems in 2016, is in the Magic Quadrant for the 12th time. With this accomplishment, it’s worth reviewing why a secure web gateway for web and cloud security is absolutely necessary to your data security strategy.

It is sometimes thought that a Next-Generation Firewall (NGFW) is all that’s really needed, because it goes further than a traditional firewall to perform deep packet inspection, application-level inspection and intrusion prevention. Not true. For sure, an NGFW fills a vital role, but the rapidly evolving threat landscape calls for the capabilities of a SWG that incorporates a web proxy server.

While a NGFW observes traffic as it passes/streams by, a proxy-based SWG intercepts traffic and terminates it if necessary. It examines all traffic between users at any location and HTTP/HTTPS sites and categorizes all URLs to identify and block malicious sites, pages and downloads, while allowing safe URLS to remain accessible. It’s simply harder to get malware through a web proxy than a NGFW. Further, a dedicated SWG incorporating a proxy architecture provides higher performance for complete inspection and malware scanning of all web traffic – a must with today’s enormous traffic volume.
