Introduction to “cisco-secure-client-win-4.3.4248.8192-isecompliance-webdeploy-k9.pkg” Software
The cisco-secure-client-win-4.3.4248.8192-isecompliance-webdeploy-k9.pkg represents a specialized compliance enforcement module for Cisco Secure Client (formerly AnyConnect) on Windows systems, designed for integration with Cisco Identity Services Engine (ISE) 3.3+ environments. This web deployment package enables automated posture assessment and policy enforcement for enterprise networks, ensuring endpoint compliance with organizational security standards before granting network access.
As part of Cisco’s Secure Client 4.3.x code train, this build (4248-8192) specifically addresses Windows 10/11 endpoint security requirements through enhanced ISE interoperability. The ISE Compliance module performs real-time checks for OS patch levels, antivirus status, and encryption configurations, aligning with NIST SP 800-53 security controls.
