Deep Web - Websites and forums that are unindexed by search engines. For example, webmail, online banking, corporate intranets, walled gardens, etc. Some of the hacker forums exist in the Deep Web, requiring credentials to enter. Dark Web - Web sources that require specific software to gain access. These sources are anonymous and closed, and include Telegram groups and invite-only forums. The Dark Web contains Tor, P2P, hacker forums, criminal marketplaces, etc. According to Etay Maor, Chief Security Strategist at Cato Networks , "We've been seeing a shift in how criminals communicate and co
