5 Best free SSL certificate providers in 2025 (free forever)

Secure Sockets Layer, mostly known by its acronym, SSL, is a security protocol that provides security by creating an encrypted link between a web browser and a web server. Generally, SSL ensures that data flow between the web server and browser is private and confidential.

By extension, SSL certificate is a data file that is hosted on the server of a website to provide SSL coverage. The information contained in an SSL certificate includes: Domain name, public key, person name or organization name, digital signature, issue date, expiry date and issuer.

An SSL seal (padlock) on the browser tells the public that a website is using SSL. And SSL is HTTPS instead of HTTP.

When you use SSL, you protect the data of your users. Users will most likely not visit your website if they know that their data is not secure. Especially if you run an eCommerce website that users may have to provide confidential information such as credit card details. Users take security serious and so should you.

Search engines generally have a bad relationship with websites that do not use SSL.

There are many benefits of using SSL and you don’t need to have any money to enjoy the cover of SSL. In this article you will find the best free SSL certificate providers. Whether you are running WordPress, Magento, Joomla, Drupal or any set up, there is a free SSL solution for you.

2. Organization Validated (OV) Certificates

OV SSL is a perfect certificate for businesses that do not require sensitive user information but might require certain information that are not sensitive. An example is businesses that use forms to capture leads but don’t ask for sensitive information such as credit card details.

3. Extended Validated (EV) Certificates

EV SSL is the most powerful SSL certificate. It can handle any sensitive information. It is ideal for businesses that require credit card details for financial transactions on their website.
