PRTG Network Monitor comes with a default SSL certificate so you can securely use the web interface through HTTPS out-of-the-box. But because it is not an official certificate that matches the domain name or IP address of your PRTG installation a web browser will always show an alert ("the certificate is not correct") when it connects to this server (although the transmission is already secure). If you want this dialog to disappear you must create, order, and install a trusted certificate. Our [latest knowledge base article](https://kb.paessler.com/en/topic/283-how-can-i-use-a-trusted-ssl-certificate-with-the-prtg-web-interface#reply-673) explains how you can do this by getting a certificate from [Comodo InstantSSL](http://www.instantssl.com/). Apart from official paid-for certificates they also offer free 90-day-certificates that work well for PRTG 7.
