What is Let's Encrypt

Let’s Encrypt is a free, automated and open certificate authority (CA) run by the Internet Security Research Group (ISRG) for the public benefit. It provides free digital certificates trusted by all the major browsers via an open API that simplifies the certificate lifecycle management with automation of the enrollment and renewal.

Why Let's Encrypt

Zero Cost

Anyone who owns a domain name can use Let's Encrypt to obtain a trusted certificate at zero cost.


All certificates issues or revoked are publicly recorded and available for anyone to inspect.


Software running on a web server can interact with Let's Encrypt to painlessly obtain a certificate, securely configure it for use, and automatically take care of renewal.


The automatic issuance and renewal protocol is published as an open standard that others can adopt.

Highly secure

Let's Encrypt serves as a platform for advancing TLS security best practices, both on the CA side and by helping site operators to properly secure their servers.

Community friendly

Much like the underlying internet protocols themselves, Let's Encrypt is a joint effort to benefit the community beyond the control of any one organization.

How to enable Let’s Encrypt on your LoadMaster

All you need to do is link the LoadMaster with your Let’s Encrypt account (if you don’t have one, you can create it from the LoadMaster UI), set the renewal period, and request a new certificate.
