Microsoft NCE Built-in Security Exchange Add-on Annual

Strengthen on-premises Exchange mailbox protection with an annual add-on designed for environments that cannot move email workloads off-premises. This Microsoft offering is built for organizations that need to preserve existing Exchange investments while adding a security layer that supports operational continuity and tighter administrative control. For infrastructure teams, the value is straightforward: keep mailbox services under your governance model while improving the security posture of a legacy or hybrid email estate. Annual licensing simplifies procurement and planning, making it easier to align spend with enterprise budgeting cycles and avoid short-term renewal churn. This add-on is a fit for organizations with compliance requirements, internal hosting constraints, or long-lived Exchange deployments that still serve business-critical users. It is especially relevant where mailbox security must be maintained without changing the underlying on-premises architecture. Choose this option when you need a Microsoft-backed security add-on for Exchange on-premises mailboxes and want predictable annual licensing for enterprise operations.
