AuthHound

AuthHound provides a really useful range of free, open-source tools for anyone dealing with Wi-Fi and RADIUS authentication issues. The Log Analyzer is particularly handy because it runs entirely in your browser, allowing you to paste output from FreeRADIUS or Windows NPS and get a plain-English diagnosis of the failure stage. It ranks the three most likely causes and gives a concrete next check for each, which is super helpful when you are stuck. The Probe CLI is equally valuable for situations where the dashboard looks clean but users still cannot connect. It finds issues that server-side tools miss, like firewalls dropping large EAP-TLS packets or a server still being soft on BlastRADIUS. It is great that the tools are reviewable and do not require uploading data. The documentation on common failures, like expired certificates or invalid Message-Authenticator errors, also adds significant value. While continuous monitoring is still coming, the current tools cover a wide range of scenarios effectively.

I am quite impressed by how AuthHound makes invisible network failures visible. The ability to paste a FreeRADIUS log and get a plain-English diagnosis with ranked causes is fantastic. It saves so much time compared to manually reading debug output. The fact that the probe is a local CLI and runs on your own hardware means I can test PEAP-MSCHAPv2 logins securely. It is excellent that the tools are open source and reviewable. My only reservation is that the continuous monitoring is still coming. For now, having these reliable diagnostic tools is enough to keep my RADIUS server running smoothly.

AuthHound offers genuinely useful, open-source diagnostics that run locally without uploading data, which is a major relief for sensitive environments. The free Analyzer and Probe tools clearly encode years of support patterns to identify RADIUS failures. While the continuous monitoring feature is still coming, the current utilities are already effective for spotting common authentication issues.

The tools seem helpful for finding where authentication breaks, though the full scope of support for every vendor is not entirely clear from the text.

From the information available, AuthHound offers a practical set of utilities for diagnosing Wi-Fi and RADIUS authentication issues. The free tools, specifically the log analyzer and the CLI probe, appear designed to make invisible network failures visible without uploading data to a cloud service. This local processing model seems ideal for keeping sensitive network logs secure. The analyzer provides plain-English diagnoses for logs from FreeRADIUS or Windows NPS, which reduces the time spent decoding technical outputs. Similarly, the probe helps identify connectivity problems like firewall packet drops. While the continuous monitoring feature is still in development, the existing open-source tools offer a solid foundation for network engineers who need to quickly pinpoint common RADIUS errors.
