ESA PXE Encryption 3-Year License Key 1K-1999 | Cisco Security — ESA-ENC-3Y-S4-K9

Keep Cisco Email Security Appliance deployments aligned to policy and procurement with a 3-year encryption license key sized for 1,000-1,999 users. This is the kind of entitlement enterprise teams choose when they need a defined term, a known user band, and a clean path for maintaining security coverage without unnecessary licensing complexity. For organizations managing regulated communications, email encryption is not a feature to improvise. It needs to be licensed, tracked, and renewed on a schedule that fits the security program. This license supports that model by giving you a specific entitlement for a specific deployment scale, which helps reduce ambiguity during audits, renewals, and budget planning. Compared with smaller or less targeted licensing options, this package is better suited to teams that want predictable coverage across a mid-sized user base. It fits environments where Cisco ESA is already part of the security stack and where the procurement team needs a term-based license that maps cleanly to operational demand.
