My main use case for Forcepoint ONE is SWG and CASB.
For my use case of Forcepoint ONE, we protect our data on the browser using SWG by granting or denying access to users based on web reputations, URLs, and category-based URLs, and we can restrict access if any user downloads something malicious through scanning. For CASB, we have integrated our Office 365 with CASB to protect our sensitive data shared with other users from Office 365 mail and Teams.
Forcepoint ONE essentially prevents or secures our users from accessing public domains without hesitation, ensuring that we scan all activities.
