Introduction to cisco-secure-client-macos-5.0.02075-vpnapi.tar.gz

The ​​cisco-secure-client-macos-5.0.02075-vpnapi.tar.gz​​ file contains the VPN API components from Cisco Secure Client 5.0.02075, designed for macOS application developers requiring programmatic VPN session management. This specialized package enables third-party software integration with Cisco’s enterprise-grade VPN services while maintaining FIPS 140-3 validated cryptographic modules for government-compliant deployments.

Released in Q2 2024 as part of Cisco’s Secure Client 5.x series, this build introduces ARM64 architecture support for Apple Silicon Macs while retaining x86_64 compatibility. The package remains backward compatible with ASA 5500-X series firewalls running ASA OS 9.16(4)+ and supports hybrid mesh VPN configurations through Cisco SD-WAN controllers.
