Cisco Anyconnect Agent

Posted onby

Hello! We are currently deploying Zscaler App to customer and having compatibility issue with Cisco AnyConnect Secure Mobility Client. The agent is only for Network access control.
We found that the issue happen when user switch from wired network to wireless network. Both network are also connected to the same corporate network internally. When user switch network, the Cisco AnyConnect Secure Mobility Client will act as NAC solution and check for 3 things before allow the user connect to internal corporate network:

  1. Check if the PC is domain-joined
  2. Check the Antivirus is installed
  3. Check the Virus signature is up-to-date
    After all checking are compliant, user will be allowed to access the internal corporate network.

The AnyConnect Umbrella module installs two agents on the localhost, AnyConnect Umbrella Roaming Security Agent, and AnyConnect SWG Agent. By default, the Roaming Security Agent is on, while the SWG Agent is disabled and must be activated in the Umbrella dashboard: Deployments Roaming Computers Settings (see below). Aug 04, 2020 Remote working has become a reality for many companies. The problem is that remotely accessing software license servers, secure sites, and networks may be both impractical and unsafe. As a unified security endpoint agent, the Cisco AnyConnect Secure Mobility Client. Vpnagent.exe file information Vpnagent.exe process in Windows Task Manager. The process known as VPN Agent Service belongs to software Cisco AnyConnect Secure Mobility Client or Cisco AnyConnect VPN Client by Cisco Systems ( Description: Vpnagent.exe is not essential for the Windows OS and causes relatively few problems. Vpnagent.exe is located in a subfolder of.

After installed Zscaler App, we found on Zscaler App that when switch between network, the ZApp will show message that indicate not able to reach internet. This is normal since Cisco agent need to complete the checking before allow the network. However after the Cisco agent completed the checking and show compliant, the ZApp still showing the same error message. We observed the symptom on the affected PC as below:

  • Not able to access any internal website
  • Not able to access internet
  • not able to resolve DNS with internal DNS server
    The issue remain the same when we try to restart the checking on Cisco agent.
    The issue is Intermittent and it does NOT happen every time when switch between network.
    It could only be resumed when user restart the PC.

May I know if there is any previous experience sharing that install Zscaler App to Cisco ISE agent environment, or any other NAC solution?
