Are the tools really free?
Yes. Every tool here is free to use, without an account. Some let you email yourself the results if you want a copy.
Do you store what I check?
Lookups are cached for a few minutes to keep the tools fast. We only keep your details if you choose to email yourself a report or ask us to get in touch.
Is it safe to check my domain?
Yes. The lookups read public information, such as DNS records and certificates, the same way any mail server or browser does. Nothing is installed and nothing is changed.
Can you fix what the tools find?
Yes. Our engineers fix these issues for businesses across the Greater Toronto Area and Canada every day. Book a free consultation and bring your results.
