Introduction to “cisco-secure-client-linux64-4.3.2584.0-isecompliance-predeploy-k9.tar.gz”
This predeployment package contains Cisco Secure Client’s ISE Compliance Module 4.3.2584.0 for 64-bit Linux systems, designed to enforce endpoint security posture assessments through Cisco Identity Services Engine (ISE) integrations. As part of Cisco’s TrustSec architecture, it enables automated device compliance verification before granting network access.
The Linux variant supports script-based deployments across enterprise environments, particularly for Red Hat Enterprise Linux (RHEL) and Ubuntu LTS distributions. Originally released in Q3 2024 as part of Cisco Secure Client 4.3 Feature Set 2, this version introduced enhanced certificate validation workflows for Linux endpoints.
