Cisco VPN AnyConnect


Multi-Factor Authentication (MFA) is an extra layer of security used when logging into websites or apps. Individuals are authenticated through more than one required security and validation procedure that only you know or have access to.

RADIUS is a protocol commonly used to authenticate, authorize, and account for user access and actions. Acceptto offers a simple solution for adding MFA to Cisco AnyConnect VPN via its Radius agent. This step-by-step integration instruction illustrates how to configure both Cisco AnyConnect VPN on Cisco ASA device and an Acceptto MFA solution.


  1. A previously set up Cisco VPN ASA with a working configuration.
  2. An Acceptto RADIUS Agent that is configured and connected to your user directory (for example Microsoft™ ‘Active Directory’) (See this page for the instructions).
  3. A user with administrative privileges for the Cisco ASA device.

Configure the Acceptto RADIUS Agent#

To integrate Acceptto with your Cisco ASA, you will need to install an Acceptto RADIUS Agent on a machine within your network. This server will receive RADIUS requests from your Cisco ASA, check with the LDAP server to perform primary authentication, and then contact Acceptto cloud service for secondary authentication.

  1. Login to the Acceptto RADIUS Agent with an administrative user and open the radius-agent-config.env file with an editor. It is located in the installed directory of RADIUS Agent. RADIUS clients are configured in this setting.

Acceptto RADIUS login

  1. Go to the bottom of radius-agent-config.env file and change the ARA_CLIENTS attribute as follows. The values should be separated by semicolon (;).

    ARA_CLIENTS = An optional name for your Cisco ASA; Internal IP address of your ASA; a shared secret

    An example configuration might look like this:

    ARA_CLIENTS = Cisco;;testing12345

Acceptto RADIUS config

  1. Save file and run the following command for set changes:

    docker-compose down && docker-compose up -d
