Cisco CES PXE Encryption 1YR License Key, 500K-999,999 Users

Secure email communications at enterprise scale with Cisco CES PXE Encryption licensing. This 1-year license key is sized for 500K-999,999 users, making it a fit for organizations that need broad coverage and predictable renewal planning across very large messaging populations. Encryption is a core control when sensitive data moves through email. In large environments, the challenge is not just enabling encryption, but doing so in a way that fits operational policy, user volume, and existing Cisco security workflows. This license supports that requirement with a clearly defined user band and term. For procurement teams, the value is in precision: the right capacity, the right term, and a Cisco-aligned entitlement for enterprise email security. It is a strong fit when the organization needs to extend encryption coverage without adding licensing ambiguity or overcommitting to a larger tier than required.
