Communication channels in a company give employees ways to collaborate and communicate like never before.  This makes companies more productive and efficient.  These methods of communication need constant security controls to ensure safe internal communication.  These communication channels store a great deal of confidential, sensitive, and proprietary information.  One breached channel could be devastating to the company.

This can automate alerts if anything negative happens on the company’s account.
