Introduction to cisco-secure-client-win-5.1.3.62-vpnapi.zip
Cisco Secure Client v5.1.3.62 VPN API Module represents Cisco’s evolution of its enterprise-grade remote access solution, rebranded from AnyConnect with enhanced modular architecture. This Windows-specific package (released April 28, 2024) provides programmatic control over VPN connectivity through its API interface, enabling IT administrators to automate secure network access workflows.
The VPN API module integrates with Cisco Secure Firewall ASA (9.12.4+), Firepower NGFW, and ISE platforms, serving as the backbone for custom security policy enforcement and zero-trust network access implementations. Designed for Windows 10/11 (64-bit) and Server 2016-2022 systems, it maintains backward compatibility with existing AnyConnect deployments while introducing next-generation encryption standards.
