SSL Checker
Check any website's SSL certificate in seconds. This free SSL checker connects to the site the way a browser does and reads the live certificate — who issued it, when it expires, how many days are left, and whether it actually matches the domain. Catch an expiring certificate before your visitors see a security warning.
💡 We read the certificate the server presents on port 443 right now — nothing is cached. This checks validity, expiry, and hostname match; it is not a full cryptographic audit of your server's TLS configuration.
How the SSL checker works
A real TLS handshake, not a lookup in someone's database.
Enter the domain
Your own site, or one you're about to trust with a payment.
We connect over HTTPS
Our server opens a secure connection and captures the certificate presented.
Read the verdict
Issuer, validity window, days remaining, and whether it covers the domain.
What an SSL certificate check tells you
Four things matter, and this SSL certificate checker reports all four. Is it valid right now — a certificate has a start and an end date, and an expired one makes every browser show a full-page warning. How long is left — a Let's Encrypt certificate lasts 90 days and certificate lifetimes across the industry keep getting shorter, so renewal has to happen automatically, not whenever you remember. Who issued it — Let's Encrypt, Google Trust Services, DigiCert and others are all fine; a self-signed certificate is not, because browsers won't trust it. Does it match the domain — a certificate issued for one name doesn't cover another, and a mismatch triggers the same scary warning as an expired one.
The cost of getting this wrong is immediate. Visitors see "Your connection is not private", almost all of them leave, and your enquiries stop that day. It is also an easy thing to lose track of, because nothing on your website looks wrong until the moment it breaks.
HTTPS, hosting, and staying secure
Almost every host now offers a free Let's Encrypt certificate with automatic renewal — if yours doesn't, that is a reason to move. New to how the pieces fit together? Read the difference between domain and hosting, our guide to adding an SSL certificate to your website, and how to choose web hosting in India.
A valid certificate is one part of a healthy site. Check your domain isn't about to expire either with the domain age checker, make sure switching to HTTPS didn't leave broken links behind using the broken link checker, and confirm your HTTP-to-HTTPS rules work with the redirect checker. We handle certificates, renewals, and mixed-content fixes for clients through hosting and domain support and ongoing website maintenance.
SSL checker — FAQs
How often should I check my SSL certificate?
If renewal is automated, a check every few months is enough. If you installed it manually, check monthly — and definitely after any host or server change.
My certificate expires in a few days. What do I do?
Renew it now from your host's control panel — most have a one-click or automatic option. If it expired already, visitors are seeing a security warning right this minute, so treat it as urgent.
Is a free Let's Encrypt certificate good enough?
Yes, for the vast majority of business websites. Browsers trust it exactly like a paid one; the encryption is identical. Paid certificates mainly add warranties and organisation validation.
Why does it say the certificate doesn't match my domain?
Usually the certificate was issued for the www version and not the plain one (or the other way round), or it belongs to the server's shared hostname. Reissue it covering both names. Test each one separately here — we check the exact hostname you type, so example.com and www.example.com give separate answers.
Does HTTPS help SEO?
Yes — Google has confirmed HTTPS is a lightweight ranking signal, and modern browsers mark HTTP pages as "not secure", which hurts trust far more than the ranking effect helps.
Never let a certificate expire again
We monitor certificates, domains, and renewals for our maintenance clients so this never becomes an emergency.
