Cisco ESA-SO-1Y-S13 Sophos Anti-Virus 1-Year License

Defend large email environments with Cisco ESA-SO-1Y-S13, a 1-year Sophos Anti-Virus license key for 250,000 to 499,999 users. This licensing tier is intended for organizations that need email security coverage at enterprise scale, where message volume, user count, and risk exposure demand more than basic filtering. For procurement and infrastructure teams, the appeal is straightforward: align protection to a large user base without overbuying capacity you do not need. A license in this range is suited to organizations with broad mail footprints, distributed business units, or compliance requirements that call for stronger control over malware delivery through email. This is a licensing item, not a physical appliance. It is designed to extend email security capabilities within an existing Cisco email security environment. Compared with smaller tiers, this option is built for larger deployments where consistency, coverage, and administrative simplicity matter. It helps justify the investment by matching protection to the scale of the environment it serves.
