Traditional security appliances - like Blue Coat's ProxySG - leverage URL filtering to provide security in a Web 1.0 world of static content and threats. Today, the web is dynamic and ever-changing-with threats moving faster than signature patches and updates can hope to keep up with. The only way to stay ahead of today's advanced threats is with a dynamic, real-time security architecture that stops threats inline - while scanning all traffic for malicious content and attacks. Appliances were never designed for the security and mobility needs of today. Only a true, purpose-built and borderless global security cloud has the power and scale to secure against today's advanced Web 2.0 threats.
