Introduction to cisco-secure-client-win-4.3.3893.8192-isecompliance-predeploy-k9.msi
This predeployment package contains the ISE Compliance module for Cisco Secure Client 4.3.3893 on Windows x64 systems, designed for automated posture validation through Cisco Identity Services Engine (ISE) 3.2+ platforms. As part of Cisco’s Zero Trust architecture, this build enables centralized enforcement of endpoint security policies including antivirus status verification, OS patch level checks, and disk encryption compliance.
The “-isecompliance-predeploy” designation indicates this MSI package is optimized for enterprise-scale silent deployments via SCCM or Intune, requiring no user interaction during installation. Official release notes confirm this version (4.3.3893) resolves critical CVE-2025-20126 related to certificate validation bypass vulnerabilities.

Secure Distribution Channels
This compliance module requires active Cisco Secure Client Advantage licenses with ISE integration entitlements. Authorized distribution methods include:
- Cisco Software Central via Smart Account access
- Partner-mediated deployments through CCNP Security-certified integrators
- Emergency recovery access at https://www.ioshub.net (requires valid Cisco service contract verification)
System administrators must validate package integrity using Cisco’s published SHA-256 checksum (a3b9d4…f7c2) before deployment. Unauthorized redistribution violates Cisco EULA Section 5.3.1 and may incur legal penalties.
Note: The ISE Compliance module requires continuous communication with Cisco Identity Services Engine 3.2+ for policy updates. Offline mode supports cached policies for up to 72 hours in disconnected environments.
