Frequently asked questions
How do I receive my audit report?
Your report is delivered to the email address you enter in the form above. The instant on-demand audit (Only Audit) is processed within minutes, so you usually receive it the same minute you submit your request.
When do I get the 7-day monitoring results?
If you enable Performance Monitoring, we run availability and performance probes against your URL for 7 days. No additional email is sent at the end: once the window finishes, the completed 7-day report is simply added to your existing audit.
What data do you collect?
We collect only what is needed to run and deliver your audit: the URL you submit, the email address used to send the report, and basic technical details of your request (your IPv4 and IPv6 address and your browser user agent). This data is processed solely for testing and analysis, stored in our Czech Republic datacenters, and is never shared with or disclosed to third parties.
Is the audit free?
Yes. The on-demand audit and the 7-day performance monitoring report are free. Extended Protection and CDN testing over 14 days is available as an additional option.
Do I need to install anything?
No installation is required. Every check runs from WEDOS global probes and our Anycast infrastructure. You only provide a URL and an email, with no agent, plugin, or DNS change needed to receive your first report.
