Netlify is now offering free SSL certificates to all its users, thanks to a partnership with Let's Encrypt. This move promotes security as a default and aims to make HTTPS more accessible to the web development community. To achieve this, Netlify has overcome technical challenges such as managing large volumes of certificates on a global network. With one click install, users can instantly get an SSL certificate, and Netlify will handle renewals automatically. The integration with Let's Encrypt is a significant step towards encrypting the majority of the web's traffic, making it easier for developers to secure their sites.
