| As web threats evolve traditional threat detection technologies are rapidly becoming obsolete and leaving the user vulnerable. In an Internet of static pages, black listing through URL categorization was sufficient to mitigate risk. As viruses and spyware evolved, threat detection technologies became signature-based, relying on comparing data with a list of known threats. Today’s threats, however, bypass all of these detection technologies. These threats — malicious content, botnets, and cross site scripting — are dynamic, their detection requires inspection of the content, or body, of the data being retrieved. |
| In theory content inspection sounds ideal; in practice the latency of traffic through traditional proxies becomes painfully high when they inspect content. Zscaler is the only SaaS web security company that has purpose-built its proxies to perform this full content inspection at ultra-high speeds. This real-time, in-line analysis includes multiple detection technologies—combining knowledge of domain, knowledge of signature, knowledge of content, and behavior analysis—to dynamically assign each page a Page Risk Index. |
| The Page Risk Index is calculated through a bi-directional inspection of content in real-time. |
