Knowledge base

RADIUS (Remote Authentication Dial In User Service) is a network protocol for communications between a remote access server and a central server for the purposes of secure authentication, authorization, and tracking of network users. The RADIUS protocol is widely used in local and corporate networks, VPN and Wi-Fi networks.

Protecting access to critical information and corporate accounts with a standard password has long been proven ineffective. Phishing, social engineering, brute force attacks, man in the middle hacks, and Trojans are just a few of the possible ways to find out your password. Two-factor authentication using one-time passwords helps protect against each of these threats. If your corporate system uses in its work the RADIUS protocol, two-factor authentication from Protectimus will help you achieve a higher level of security today!

Want two-factor authentication for your company’s systems, but your setup isn’t on the list of supported devices or software? That’s easily fixed! We are constantly working on expanding our list of supported implementations, and offer our customers the opportunity to customize Protectimus’ 2FA solutions to meet their requirements. If your device or system supports RADIUS, our engineers can make it work. Besides 2FA for RADIUS, we offer ready-made integrations for the protocols SAML and LDAP, as well as a complete SDK on PHP, Java, and Python.

There are 4 ways available to deliver one-time passwords: e-mail, SMS, hardware, and software tokens. Although SMS-authentication is the most popular, it is more secure to use hardware tokens. They eliminate the possibility of intercepting the OTP. A convenient and more affordable alternative to hardware OTP generators are software applications for Android and iOS smartphones. But there is a risk of the smartphone being compromised, possibly leaking one-time passwords. So hardware tokens are still the most secure.

Our 2FA solution supports the RADIUS protocol, by which you can easily integrate it with Citrix NetScaler Gateway, VMware Horizon, and other similar platforms. We also support the SAML and LDAP protocols. There are also open source software development kits for PHP, Python, and Java. But even if some of the ready-made plug-ins or the SDK are not suitable for your company, contact us! We provide free consultations and can adjust our two-factor authentication solution to meet your specific requirements.
