SSL
SSL is a certificate that encrypts the connection between a visitor and your website. Sites with SSL use addresses that start with https, and the browser shows a padlock.
What is SSL?
SSL is a certificate that encrypts data travelling between your site and a visitor. The technology in use today is actually called TLS, but the SSL name stuck. Sites with a certificate use https addresses. Certificates expire and must be renewed.
Here is an everyday case. A customer types their name and phone number into your contact form. Without SSL, that travels as plain text and someone in between could read it. With SSL, it is encrypted. If the certificate expires, the browser shows a security warning and most people leave.
Why does it matter?
SSL protects visitor data and builds trust. Browsers mark pages without it as not secure, and a site that takes payments needs it. We track certificate renewals as part of maintenance and support. What else a site collecting personal data needs is covered in a KVKK-compliant website.
Frequently asked questions
Do SSL certificates cost money?
Not always. Authorities such as Let's Encrypt issue free certificates that are enough for most sites. Paid certificates offer other validation levels and support.
What happens when an SSL certificate expires?
The browser shows visitors a security warning and most of them leave. Forms and payment pages lose trust too, so renewals should be automated and monitored.
What is the difference between SSL and HTTPS?
SSL is the certificate. HTTPS is the encrypted connection made with it. The technology in use today is TLS, but the SSL name stuck.
