Enterprise Browser is not a new concept, at all. Both Chrome and Edge has Enterprise Browser versions for years, with central control capabilities like these built in and controllable by the enterprise admin. See more here:

Also, keeping a browser software itself secure from all external threats is a very very tall order. Both Google and Microsoft have large teams of security experts and trillions of daily points collected that helps to find and fix security issues in the browser software itself. Not sure one can trust a very early product and nascent software - while copy-paste by employees may have been controlled, the real hackers may not be prevented from exploiting the security issues in complex browser software that Google and Microsoft fix on a daily basis.

This startup will have a very hard time to compete or replace either Chrome or Safari, when enterprises who care about such central controls can turn on such tech within Chrome and Safari itself. Enterprises who would want to silently monitor will simply turn on such control capabilities in common browsers, vs blatantly asking their teams to switch and use a browsers that is only known for such monitoring--- LoL
