Rahvion Diagnostics
Type any domain and get the same core checks the big toolboxes run: DNS records, the SSL certificate behind the padlock, blacklist status, and how the site answers. If a website ever showed you a security warning, run its domain here and this page will show you exactly why, in plain English.
Checks run live from Rahvion's server at the moment you ask. Each result card also links to the same lookup on MX Toolbox so you can cross-check us. Honest note: this page's data is Rahvion's own live check, not MX Toolbox's. If we add a paid MX Toolbox API key later, this page switches to their API automatically and will say so.
Seeing a warning on a site you trust?
Do not click through it and never enter a password past one. Run the domain here, read the plain-English reason, and if it is a site you pay or bank with, call the company on a number you already have. That is exactly the kind of thing Rahvion members call us about. Book a free Tech Safety Check →
