Cisco CES O365 Inbound Security 3YR, 500 | Cloud Security Licensing — L-CES-O365I-3Y-S3

Secure inbound Microsoft 365 email traffic with a 3-year Cisco CES subscription for 500 users. This licensing package is designed for organizations that treat email as a primary attack surface and need a structured way to reduce inbound risk without fragmenting security operations. A multi-year term helps teams lock in coverage, simplify renewal planning, and keep protection aligned with the broader Microsoft 365 security stack. For procurement and IT operations, the 500-user quantity supports a defined deployment scope, making it easier to map the license to a business unit, tenant segment, or standardized user population. This is the kind of purchase that makes sense when email security must be dependable, budgetable, and easy to administer over time. Rather than managing short-term renewals or piecing together point solutions, this Cisco subscription gives teams a clear path to maintain inbound protection across the full term. It is a practical fit for enterprises that want to reduce exposure from malicious attachments, phiJTFng attempts, and other inbound threats while keeping licensing straightforward.
