About Let's Encrypt

Let’s Encrypt, founded in 2013, is an innovative player in the Cyber Security and Internet industries, with headquarters in the United States. As a free, automated, and open certificate authority (CA), it is dedicated to advancing web security by enabling HTTPS (SSL/TLS) for websites at no cost, thereby promoting a more secure and privacy-respecting internet environment.

The core of Let’s Encrypt's value proposition lies in its five guiding principles: offering certificates at zero cost, automating certificate issuance and renewal, advancing security practices, maintaining transparent operations through public logging, and adhering to open standards for global adoption. Unique in its approach, Let’s Encrypt is a cooperative effort managed by the Internet Security Research Group (ISRG).

Despite no recent investments, Let's Encrypt's mission positions it as a crucial contributor to internet security, providing scalable and trusted solutions without monetary barriers.
