Microsoft 365 E3 vs. E5: Insider Risk

• Microsoft 365 E3 customers can buy an Insider Risk Management add-on license to reduce risks of employees or other insiders abusing Microsoft 365 services.
• Regulated communication over Teams is the likeliest driver for an Insider Risk Management purchase.
• Customers who need Insider Risk Management might end up buying a larger Microsoft 365 E5 suite.

An Insider Risk Management add-on license offers Microsoft 365 E3 customers tools to reduce risks from acts by insiders that abuse Microsoft 365 services. For example, it can help prevent employees from using services to harass colleagues or otherwise send inappropriate communications, and detect IT staff or Microsoft support engineers misusing administrative privileges.

Insider Risk Management will benefit any customer hoping to minimize litigation and security threats. It will particularly interest customers who must monitor internal communications and administrators to meet formal security standards or regulatory requirements, but these customers might end up needing a larger Microsoft 365 E5 suite.
