Symantec Web Security Service

Symantec Web Security Service (now part of the massive Broadcom empire) is an incredibly powerful, heavily entrenched veteran titan that mathematically defines the "Enterprise Data Loss Prevention (DLP)" overlap. It is famous for its terrifyingly strict control over what leaves a corporate network. It is the absolute weapon of choice for highly regulated global banks who mathematically demand a gateway that will instantly block an employee attempting to upload an encrypted zip file to a personal Dropbox.
