Enabling Two-Factor Authentication on Check Point VPN

This guide shows how to enable Check Point VPN two-factor authentication (2FA) integrating Check Point VPN with Protectimus multi-factor authentication service or on-premise MFA platform via RADIUS.

Two-factor authentication (2FA) 2FA will protect your users’ accounts and, consequently, your corporate infrastructure from unauthorized access. By activating Check Point VPN 2FA, you protect your users’ accounts from phishing, brute force, data spoofing, keyloggers, man-in-the-middle, social engineering, and a bunch of other cyber attacks.

1. How Check Point VPN Two-Factor Authentication (2FA) Works

Two-factor authentication means using two different types of authenticators to get access to the Check Point account protected with 2FA.

1. At first, the user enters a standard password and username (something the user knows);
2. Then they enter a one-time password received with the help of a 2FA token or a smartphone (something the user owns).

Thus, when Check Point VPN 2FA is enabled, it becomes too hard to hack both two-factor authentication passwords at the same time, especially considering that a one-time password is valid only for 30 seconds.

This guide shows how you can set up Check Point 2FA via the RADIUS authentication protocol using the Protectimus Cloud Two-Factor Authentication Service or Protectimus On-Premise 2FA Platform.

2. How to Enable Check Point VPN 2FA

You can set up Check Point VPN two-factor authentication (2FA) with Protectimus using the RADIUS protocol:

1. Get registered with Protectimus SAAS Service or install the On-Premise 2FA Platform and configure basic settings.
2. Install and configure Protectimus RADIUS Server.
3. Configure Check Point VPN authentication policies.
