Hi,
Cisco NAC Agent
The Cisco NAC Agent provides local-machine Agent-based posture assessment and remediation for client machines. The Cisco NAC Agent is designed to provide user login capability on a wide range of Windows client machines, including clients running 64-bit operating systems, and offers "double-byte" support to enable native localization for a large variety of languages.
Users download and install the Cisco NAC Agent (read-only client software), which can check the host registry, processes, applications, and services. The Cisco NAC Agent can be used to perform Windows updates or antivirus/antispyware definition updates, launch qualified remediation programs, distribute files uploaded to the Clean Access Manager, distribute website links to websites in order for users to download files to fix their systems, or simply distribute information/instructions.
Cisco AnyConnect VPN Client
The Cisco AnyConnect VPN Client provides remote users with secure VPN connections to the Cisco ASA 5500 Series Adaptive Security Appliance using the Secure Socket Layer (SSL) protocol and the Datagram TLS (DTLS) protocol. AnyConnect provides remote end users with the benefits of a Cisco SSL VPN client, and supports applications and functions unavailable to a clientless, browser-based SSL VPN connection.
