What is a FreeSSL Certificate?
FreeSSL is a FULLY FUNCTIONAL single root test certificate valid for 30 days. It is the only fully trusted single root trial certificate available. If you need to test your server, or would like to test our support and issuance speed then FreeSSL is an ideal solution.

FreeSSL certificates have the same browser recognition rates as both our StarterSSL and ChainedSSL Wildcard, and upgrading to either one of these certificate is easy.
