What SSL does — and why the padlock matters
SSL (now technically TLS) wraps the connection between a visitor's browser and your server in encryption. Without it, anything sent — passwords, form data, the pages themselves — travels in the open and can be read or tampered with on the way. With it, that traffic is scrambled end to end and can't be quietly altered.
The padlock in the address bar is the browser telling the visitor that a valid certificate is in place and the connection is private. A site without it now shows a "Not secure" warning, which costs trust and conversions before a visitor reads a single word.
Why SSL is free now
For years certificates were something you bought. That changed with Let's Encrypt and the ACME standard, which issue domain-validated certificates automatically and at no cost. A free certificate uses the same encryption and is trusted by every browser exactly like a paid one — the padlock looks identical.
Paid certificates still exist for organization or extended validation (showing a verified company name), but for the vast majority of sites a free, auto-issued certificate is all you need. The real difference between setups today is not price — it is whether renewal is handled for you.
Getting SSL that renews itself
Free certificates are short-lived on purpose — typically 90 days — so a certificate you install by hand becomes a recurring chore, and a missed renewal means every visitor suddenly hits a security warning. The fix is automation: let your CDN or hosting platform issue and renew the certificate for you.
On cdn.com.tr, SSL is automatic and always on. When you point a domain through the platform, a certificate is issued for it and renewed before it expires — no manual steps, no downtime, no expiry surprises. You get HTTPS everywhere without thinking about it.
When SSL matters most
Logins, contact forms and checkout all send data that must be encrypted — SSL is non-negotiable the moment a visitor types anything.
HTTPS is a Google ranking signal, and removing the "Not secure" label lifts trust and conversions on every page.
One managed setup can cover your root domain and every subdomain, so shop, blog and app are all secured together.
SSL FAQ
Is a free SSL certificate as secure as a paid one?
Yes. A free domain-validated certificate uses the same encryption and is trusted by every browser identically. Paid certificates differ only in the validation shown (organization or extended), not in the strength of the encryption.
How often does SSL need renewing?
Free certificates are typically valid for 90 days. Renewing by hand every few months is error-prone, so automatic renewal — where the platform reissues the certificate before it expires — is the practical way to avoid warnings.
Will adding SSL break my site?
It should not, but mixed content (images or scripts still loaded over http) can trigger warnings. A managed setup that serves everything over https and redirects http to https avoids this; on cdn.com.tr that redirect and the certificate are handled for you.
