Introduction to “anyconnect-win-4.10.07073-vpnapi.zip” Software

This VPN API module (anyconnect-win-4.10.07073-vpnapi.zip) is a critical component of Cisco’s Secure Mobility Client 4.10.07073 release, designed to enable third-party applications to integrate with Cisco’s enterprise-grade VPN infrastructure. As part of Cisco’s August 2023 software update cycle, this version focuses on enhancing API stability for developers and system administrators working with Cisco ASA firewalls (5500-X series) and Firepower Threat Defense (FTD) appliances.

The package specifically provides programmatic access to VPN tunnel configurations, session diagnostics, and encrypted connectivity features. Cisco officially supports this module on Windows 10 (64-bit) and Windows 11 systems, with backward compatibility maintained for Windows Server 2019 deployments.
