Free checks for your website, domain and email
Each checker runs on your own address, shows its result straight away and explains what it means and how to fix it. No sign-up.

Check any website’s SSL certificate: when it expires, whether browsers trust its chain, whether HTTPS answers and which authorities may issue it. Free, no sign-up.

Check what public DNS answers for your domain – address records, name servers and DNSSEC signatures – and whether DNS is why a site is down.
Open the checkerEmail security checker
Check your domain’s SPF and DMARC records – the DNS records that tell receiving servers your email really comes from you. Free, no sign-up.
