There’s been a bit of a drop in performance for the application because of the encryption layer. The initial setup can be a little tricky since you really need to understand the documentation, as everything has to be configured in the stunnel.conf file. Also, it only focuses on encrypting traffic and doesn’t offer any features for intrusion detection or prevention, which is a bit of a downside. Review collected by and hosted on G2.com.
