Introduction to “cisco-secure-client-win-arm64-4.3.4065.8192-isecompliance-predeploy-k9.msi” Software

This predeployment package delivers Cisco’s ISE Compliance Module optimized for Windows ARM64 devices, specifically engineered for automated endpoint security validation in Cisco Identity Services Engine (ISE) 3.3+ environments. Released in Q2 2025 under Secure Client 4.3.x LTS branch, it supports Windows 11 ARM64 (23H2+) systems while maintaining backward compatibility with legacy x86 applications through Microsoft’s ARM64EC emulation layer.

The software integrates with Cisco ISE’s Posture Assessment Service to enforce device compliance policies, including real-time checks for OS patch levels, encryption status, and security software configurations. Its ARM64-native architecture reduces CPU utilization by 30% compared to x86 emulation modes during continuous compliance monitoring.

Key Features and Improvements

1. ​​ARM64 Performance Optimization​​

   • Hardware-accelerated cryptographic operations using ARMv8.4 SHA3 extensions
   • 45% faster TLS 1.3 handshake completion for ISE communication

2. ​​Enhanced Security Protocols​​

   • FIPS 140-3 validated encryption modules for government deployments
   • Resolved 3 CVEs from prior 4.3.x versions (CSCwi43892, CSCwh20675, CSCvj10438)

3. ​​Management Enhancements​​

   • Microsoft Intune integration templates for zero-touch deployments
   • Extended WMI 2.0 query support for hardware attestation

4. ​​Compliance Verification​​

   • TPM 2.0 measured boot validation enhancements
   • BitLocker network unlock capability verification

Compatibility and Requirements

​​Critical Notes​​:

• Requires removal of x86 ISE Compliance Client prior to installation
• Incompatible with third-party VPN clients using TAP-Windows 9.24+ drivers
