Proofpoint Expands AI-Powered Investigations to Microsoft 365 and Deepens Insider Risk Visibility Into AI Activity

Investigation capabilities extend to Microsoft 365 with insider risk visibility into employee AI tool activity.
Proofpoint extended its AI-powered investigation capabilities to Microsoft 365 and added insider risk visibility into employee AI tool activity.
The AI activity monitoring addresses a gap organizations have consistently reported, where employees reach AI tools through personal accounts that produce no corporate log record, making data movement into those tools invisible.
Bringing that activity into an insider risk programme is the step most organizations have not taken. Teams evaluating it should confirm which AI services are actually covered and whether detection depends on managed browser or endpoint agents.
