Introduction to s42700x15_0_0_ec.ova

This Open Virtualization Archive (OVA) package contains the enterprise-grade deployment template for Cisco Expressway X15.0 series collaboration gateways, designed to enable secure B2B/B2C communication across hybrid cloud environments. Released on December 18, 2023, it implements NIST SP 800-193 platform resilience standards with FIPS 140-3 Level 2 validated encryption modules.

The virtual appliance supports zero-touch provisioning of Expressway X15.0 instances in VMware ESXi 8.0 U3+ environments, addressing CVE-2025-3821 vulnerability identified in Cisco Security Advisory 2025-CAT-07. It enables unified management of video/voice collaboration resources while maintaining backward compatibility with Webex Edge Connect 3.1+ integrations.
