RADIUS servers represent a vital aspect of many IT environments. They enable IT admins to maintain control over their networks by knowing who exactly has access to a given network. Despite this benefit, many find that using a RADIUS server presents difficult challenges including cost concerns and ongoing maintenance. That’s why the concept of on-demand RADIUS servers excites IT admins.
Why Should You Use RADIUS?
RADIUS authentication requires that users enter their own unique set of credentials to access a network or virtual private network (VPN). Essentially, RADIUS connects user identities stored in a directory service, such as Active Directory®, to networking components. The benefits exist on a couple different levels: security improvements and centralized user authentication.
Security Benefit of RADIUS
Centrally managing users from your core directory enables IT admins to cut user access to vital networking assets at once. If an employee leaves the company, an IT admin removes the user from their core directory and their network / VPN access ceases. Having the ability to quickly deprovision users from network / VPN access ensures that only the right people can access these critical resources.
Benefit of Centralized User Authentication
Centralized authentication makes it easy to enable access to networks via diverse sets of networking gear. With RADIUS, IT admins point their networking gear to a centralized server. That RADIUS server then checks any requests against the directory service to ensure only authorized users receive access. This means your users enjoy ease of login despite their location. For example, a user could request access from a conference room, their desk, or another wing of the building and still achieve network access via their unique credentials.
What Challenges Does On-Prem RADIUS Present?
While RADIUS provides excellent benefits for organizations looking to increase their network security, those benefits come with drawbacks associated with setting the servers up. Chief amongst these drawbacks is the extensive integration work that RADIUS servers require to make functional. IT admins need to integrate the server with their identity provider, systems, WAPs, VPNs, switches, and routers.
How Can an On-Demand RADIUS Server Save Time and Hassle?
For organizations that want to use the RADIUS protocol without the setup and ongoing maintenance, on-demand RADIUS servers facilitate authentication to networks and VPNs. With RADIUS-as-a-Service, or a cloud-based RADIUS provider on your side, you get a third-party team of experts that work around the clock to ensure your RADIUS server is available and secure.
Additionally, when IT admins leverage on-demand RADIUS servers, organizations only pay for the users that they put into the platform. In that same vein, the service is ready to scale alongside your growth, so you don’t need to worry about handling that scale yourself.
