The generic name for these types of solutions is DLP or data loss prevention. DLP solutions are common in regulated industries with finance typically having the most extreme forms of DLP solutions implemented. 1) DLP solutions for email and cloud storage: Office 365 and GSuite both have a bundled DLP solution. 3rd party solutions are also fairly comprehensive. 2) DLP solutions for workstations. This can range from sharing being disabled via MDM to DLP monitoring software (sometimes bundled in anti-virus) to some type of Desktop as a service solution (See techjuice's answer for more info on the last choice). 3) DLP server solutions, these can monitor for and disable certain sharing protocols.
