Cisco CES O365 Premium Security 3 Yr, 500 | Cloud Security, Licensing — L-CES-O365P-3Y-S3

Protect Microsoft 365 users with a 3-year Cisco subscription designed for 500 seats. This licensing package supports organizations that need dependable cloud security coverage across email and collaboration workflows, with procurement simplicity that aligns to multi-year budgeting. It is suited to teams standardizing on Cisco security services and looking to extend protection without adding hardware or complex deployment overhead. For enterprise IT, the value is in predictable coverage and scale. A 500-user license helps security teams match protection to a defined population, while the 3-year term reduces renewal churn and supports longer planning horizons. That matters when you are defending user identities, inboxes, and cloud productivity tools against constant credential attacks and malicious content. Compared with shorter-term or smaller-seat alternatives, this package is built for organizations that want to lock in coverage for a meaningful user base and keep licensing administration straightforward. It is a practical fit for procurement teams that need clear term-based purchasing and for security leaders who want consistent protection across the Microsoft 365 environment.
