To answer the question of what is Web 2.0, you must first understand the evolution of the Internet. In recent years, the way we think about online content, evolving to applications, interactive mediums and streaming media has changed. This paradigm shift from Web 1.0 to Web 2.0 has already occurred, and soon, Web 3.0 will begin taking over the Internet, changing the way we access information, content and applications again.
Web 1.0 was the era of Geocities, Netscape and static HTML websites. The beginning incarnation of the Web was a read-only, content-based Internet where people simply found websites and read the content they presented. This first generation was all about static content, which is relatively easy to secure. Many Secure Web Gateways were designed around this Web 1.0 concept, with protection centering around content filtering or a simple URL database.

Web 2.0 is a change or evolution from static content to interactive with content, allowing users to work within applications and generating content in real-time. Web 2.0 is the era of Google, iTunes, Facebook, Twitter, YouTube and much more. Interacting, sharing and collaborating with content has dramatically changed the Internet, with the focus now on social networking, Web applications, wikis, blogs, peer-to-peer, chat, streaming media and dynamic content. This presents many challenges for network security, which must now be able to identify all of the forms of Web 2.0 that appear across multiple ports and protocols, and protect, control and manage Web 2.0 applications, content and mediums. DeepNines Secure Web Gateway was architected for the Web 2.0 world, unlike much of the industry that relies on simple content filters or blacklist databases for static content.
Web 3.0 is on its way, even faster than you may realize. Web 3.0 is about semantic Web, which involves the ultimate personalization of data, intelligence with searching for content or applications, and behavioral constructs for interaction. Also, Web 3.0 is about portability, taking this new interactive, personalized data to mobile devices. Web 3.0 makes it possible to understand the human side of the Internet with regards to intent and expressions, for example Microsoft’s Bing search and decision engine and Amazon’s recommended products based on other shoppers’ like-interests.
