Common Questions
Does this cover every Defender product?
This tool covers Defender for Office 365 and Defender for Endpoint specifically — the two products with the clearest Plan 1/Plan 2 tier distinction covered in this cluster.
Should we always choose Plan 2 if budget allows?
Not automatically — Plan 2's investigative and hunting tools deliver value only when someone actively uses them. See the linked articles for the staffing consideration behind this decision.
Are these feature lists guaranteed to reflect Microsoft's current offering?
Microsoft periodically changes plan feature boundaries and naming. Treat this comparison as a directional starting point and confirm current plan contents directly with Microsoft or a licensing partner before making a purchasing decision.
