Addresses a genuinely emerging enterprise need for AI agent-specific governance and security
Included at no extra cost within Microsoft 365 E7, simplifying costs for E7 subscribers
One per-user license covers governance for all of that person’s AI agents, not billed per-agent

Requires a prerequisite qualifying Microsoft 365 subscription (E5, Defender + Purview Suite FLW, or Business Premium)
Standalone add-on cost ($15/user/month) adds to existing Microsoft 365 licensing costs
Relatively new product (GA since May 2026), so long-term enterprise track record is still building

Largest user base and ecosystem of any AI assistant, with the most third-party integrations
Genuinely broad capability across writing, coding, research, and file analysis
Custom GPTs allow tailoring the assistant to specific repeated tasks
Frequent model updates keep it competitive on raw capability

Free tier has usage limits and access to a lower-tier model than paid plans
Can produce confident-sounding but incorrect information, especially without browsing enabled
Breadth can mean less depth than a tool purpose-built for one specific workflow
Data usage and training policies require attention for sensitive or regulated work
