RADIUS Monitor
Upgrade your company’s network security and performance with ease
Measure response times for your RADIUS authentication servers
Bolster network access security with SolarWinds® Server & Application Monitor (SAM). More easily monitor the availability of your Remote Authentication Dial-In User Service (RADIUS) servers, measure authentication response times, and compare them against predetermined thresholds or SLAs. SAM records each step of a client’s network behavior for constructive playback and comprehensive load-time testing. Plus, you can record from multiple locations to help ensure test accuracy.
Monitor the availability and performance of your Windows-based RADIUS server
Ensure your enterprise’s network is running correctly at all times, so users aren’t left in the dark. The SAM Orion foundation harnesses data from Microsoft’s Network Policy Service (NPS), which manages the authentication, authorization, auditing, and accounting processes occurring as Internet Engineering Task Force (IETF) RADIUS-compatible servers receive user access attempts.
If the NPS is not available, services depending on it will not start, and users may be unable to access the network via a VPN, dial-up, 802.1x wireless, or Ethernet connection. SAM component monitors provide you with the performance metrics needed for visibility into this service. Comprehensively scan for oddities at each checkpoint of the RADIUS server-client communication process so you can iron issues out before they impact users.
Get visibility into network functionality with the RADIUS User Experience Monitor
Help enable a streamlined experience for your network users. Your RADIUS server grants a client access to your network, but SAM goes further. While a user is connected to the network, NPS data is fed into SAM node-specific monitors to keep a running log of their activity, using information such as remote access requests, request completions, timeouts, invalid inputs, and more, and can be revisited later on for auditing or proxy redirecting. With these insights, you can help ensure optimal network functionality and a better user experience.

Do you find yourself asking…
A Remote Authentication Dial-In User Service (RADIUS) server is a background database operating on Windows® or UNIX® to connect users to networks and monitor their activity while using the network. It’s a safe and secure way for businesses to surveil behavior with the potential to negatively alter the performance or functionality of their entire IT infrastructure. The most common Windows-based RADIUS server is Microsoft’s Network Policy Server (NPS).
There are three steps involved in the process of a client-server connection: authentication, authorization, and accounting (AAA).
Authentication entails the initial connection process, wherein a client inputs credentials transmitted to a network access server for verification.
Authorization is the process where the server then receives the credentials along with an encrypted key to run for validity and subsequently grants access to the user if all information is correct. RADIUS proxies may be utilized to ensure users are guided to the correct server if multiple servers are being used.
Accounting, the final step, involves constant interaction between the RADIUS server and network-attached storage (NAS) to gain insight into the user’s session ID, data usage and transfers, network address, logout information, and more. Enterprises can use RADIUS servers to protect, manage, and mitigate any risks associated with shared network access.
