Is SSL decryption required for URL filtering?

Without SSL decryption, Internet filtering and monitoring tools can only see the top-level domain of a requested website. They can't see the full path of the request: They can't see keyword search terms or what kind of content is returned. You can only block or allow access to the top-level domain.
