Introduction to cisco-secure-client-win-arm64-5.1.4.74-predeploy-k9.zip Software
The cisco-secure-client-win-arm64-5.1.4.74-predeploy-k9.zip is Cisco’s specialized VPN deployment package for Windows 11 ARM64 devices, designed for enterprise environments requiring native 64-bit architecture support. Released in August 2024 as part of Secure Client 5.1.4 maintenance updates, this predeploy package enables centralized distribution of Always-On VPN services to Microsoft Surface Pro X and Qualcomm-powered laptops.
This build specifically addresses performance limitations in ARM64 translation layers observed in previous AnyConnect 4.x versions, achieving 92% native instruction execution efficiency through optimized cryptographic acceleration. The “predeploy-k9” designation confirms FIPS 140-3 Level 1 compliance for U.S. federal agency deployments.
