Microsoft's communication monitoring system promises to detect 'profanity', 'offensive language', 'inappropriate text' and harassment but also corporate sabotage, data leaks, bribery, money laundering, insider trading, conflicts of interest and 'workplace collusion'.
Very different purposes.
Employers can receive alerts when certain keywords are mentioned. They can “train” custom AI classifiers by providing a small number of text samples that represent the type of content they want to detect.
The system can analyze communication and document contents in Microsoft 365, Exchange, Teams, Zoom, Slack, Webex and, via custom integrations, in any other system.
Via TeleMessage's on-device access and mobile carrier partnerships it can access calls/SMS from mobile phones or even encrypted messages (e.g. Whatsapp, Signal).
Section 6 summarizes data practices/sources/purposes for the systems examined in my report. Here's the summary for the Microsoft Purview 'communication compliance' module.
