MT Intelligence
The domain has been registered for over 15 years and is officially operated by Microsoft Corporation. Our analysis confirms it serves as the primary documentation and landing hub for the SignalR open-source project. The site's infrastructure is deeply integrated with official Microsoft and Azure services, and its content matches the library's technical purpose. While one minor engine flagged it, this appears to be a false positive given the overwhelming evidence of legitimacy. There are no indicators of tech-support scams or malicious redirects.

Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on signalr.net and not a lookalike like s-ignalr.net.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
- OpenDiscuss this site on the forum

Common questions about this site, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- Our automated security review found no threat indicators on signalr.net. The site appears legitimate based on the signals we checked, but always stay alert for phishing emails that spoof real domains.

- Yes. signalr.net presents a valid TLSv1.3 certificate issued by Microsoft Corporation · Microsoft TLS G2 RSA CA OCSP 04, expiring in 108 days. Note that SSL only encrypts the connection — it does not guarantee that the site itself is trustworthy.
