Them
Bundle
Engage + Incydr + Aware + Advanced Email Security as a multi-product portfolio. Quote-based. Enterprise-gated. Microsoft co-branded whitepapers anchor the procurement story.

Gap
Cohort 3

Lead on outcome. Never on price.
Replace at Engage renewal. Email security stays with Mimecast separately.
