Cisco ESA PXE Encryption 1-Year License, 100K-249,999 Users

Secure sensitive email exchanges across a large user base with a Cisco ESA PXE encryption license built for 100,000 to 249,999 users. This 1-year entitlement supports organizations that need to maintain message confidentiality without adding operational complexity to the mail security stack. Sized for enterprise-scale deployments, this license fits environments where email remains a primary channel for regulated data, internal approvals, and customer communications. It helps standardize encryption policy across a broad population while keeping procurement aligned to a defined annual term. For IT teams, the value is in precision: the right license band, the right term, and a Cisco-backed path for extending protection within an existing email security architecture. That makes it easier to plan renewals, maintain continuity, and avoid overbuying capacity that will sit unused. For organizations with large user counts, this license supports a cleaner security posture and a more disciplined approach to compliance-driven messaging.
