Our Story

The simple but powerful belief that every web application worldwide should be secured using SSL has been the essence of ZeroSSL ever since its initial release in early 2016, when its sole purpose was to facilitate the setup and installation of free 90-day SSL certificates issued by third-party vendors. As time passed and the user base grew, a decision was made for ZeroSSL to take a significant step towards becoming a trusted certificate authority itself, issuing authentic SSL certificates.

Today, with the trust of more than 500.000 customers worldwide, ZeroSSL is built upon three main principles:

#1 Accessibility

The idea of bringing SSL protection to everybody for free or at low monthly rates has been with us since day one, and we continue to believe that not a single individual or business should struggle to afford a rock-solid SSL certificate. This is why we offer up to five 90-day SSL certificates as part of the ZeroSSL Free Plan along with unlimited 90-day SSL certificates for anybody making use of major ACME integrations for certificate management.

#2 Usability

Over the years, our team realized that another essential characteristic of a good SSL certificate authority should be giving customers complete transparency and intuitive control when it comes to SSL certificate management. This led us to building a fully-fledged SSL management user interface, which comes at no additional cost and enables customers to easily set up new certificates and keep track of existing ones.

#3 Automation

Our final main belief here at ZeroSSL is that web essentials like SSL certificates should be fully automated, which is why we offer a straightforward SSL certificate management REST API interface, which can be used to automate most tasks usually handled manually in the ZeroSSL UI. In addition, we made sure ZeroSSL is supported across all major ACME integrations around the world.
