Encryption
Helps protect information while it travels between a visitor’s browser and the website. Encryption also helps reduce the risk of data being read while in transit.
A practical guide to website security
A safer website starts with HTTPS
SSL/TLS certificates help encrypt the connection between a website and its visitors. Learn the basics, understand your options, and explore ZeroSSL as one possible provider.

Why SSL Certificates Matter
An SSL/TLS certificate helps a browser establish an encrypted HTTPS connection. It is important, but not a complete security solution by itself.
Website identity
Helps browsers verify that a connection is associated with the domain named in the certificate. Domain validation is an important step, but it does not certify that a business is honest.
HTTPS in the browser
A valid certificate enables HTTPS and helps prevent certificate-related warnings. Browsers use HTTPS to indicate that a secure connection has been established.
One part of security
Keep software updated and protect accounts and servers too; SSL alone is not enough. A layered approach combines certificates with updates, access controls and backups.

SSL / TLS
What are SSL and TLS?
SSL and TLS are protocols that help protect data exchanged between a browser and a website. TLS is the modern successor to SSL and is the protocol used by HTTPS today.
SSL: the original name
SSL stands for Secure Sockets Layer. Older SSL versions are obsolete and should not be used, but the name remains common when people talk about website certificates.
TLS: the modern standard
TLS means Transport Layer Security. Current HTTPS connections use TLS to encrypt traffic and help protect data in transit when configured correctly.

FAQ
Frequently asked questions
Is SSL free?
Some certificate options are free. Features and limits vary; check current terms. Free options may have limits on validity, quantity or available features.
Does HTTPS guarantee a safe website?
No. HTTPS encrypts the connection but does not guarantee that the content or operator is trustworthy. Continue checking the site’s software, forms and operator before sharing sensitive data.
Will the certificate install itself?
That depends on your hosting and configuration. Some setups support automation; others require manual installation. Confirm whether your hosting platform supports automatic issuance and renewal.
