Domain check
Free domain check for DNS, SSL and mail security
Enter a domain and see straight away how its certificate, DNS and email settings look — no account needed and nothing is changed.
What gets checked
The domain check pulls together the most important public information about your domain.
SSL certificate
Whether the certificate is valid, who issued it and how long it stays valid.
DNS & nameservers
How the domain resolves and which nameservers are answering for it.
Mail routing (MX)
The mail servers responsible for receiving email for the domain.
Mail protection (SPF & DMARC)
Whether SPF and DMARC records are in place to protect the domain from spoofing.
Domain expiry
The registration expiry date, where the registry makes it available.
Risk overview
A clear summary that highlights the issues worth acting on first.
Why these checks matter
Small mistakes in DNS, SSL or mail settings often have big consequences.
Expiring SSL breaks trust
An expired certificate makes browsers show a warning and can stop visitors and customers from reaching your site.
SPF and DMARC protect your email
Without them, others can send email in your domain's name and your own messages are more likely to land in spam.
Domain expiry is easy to miss
A lapsed registration can take a domain — and everything on it — offline. Monitoring catches it in time.
DNS errors affect mail and web
A single wrong record can break your website, your email or both. Regular checks surface problems early.
Domain check questions
Yes. The public domain check is free to use and does not require an account.
