John is seeking to implement a solution that can offer content filtering for web applications, CASB (Cloud Access Security Broker) functionality, DLP (Data Loss Prevention), and threat protection. What type of solution can he deploy to deliver these capabilities?

Next-generation (NG) secure web gateways (SWG) offer enhanced functionalities that go beyond what is found in cloud access security brokers and next generation firewalls. While the features available may differ, they may include web filtering, advanced threat protection, TLS decryption to enable traffic analysis, cloud access security broker (CASB) features, data loss prevention (DLP), and other advanced capabilities. This kind of solution is relatively recent, and the market is evolving rapidly.
