Secure PRTG web interface connection

PRTG comes with a default SSL certificate. It allows you to securely use the PRTG web interface via HTTPS. The connection is encrypted and no unauthorized person is able to see your data.

However, since the default certificate does not match the domain name or IP address of your PRTG installation, your web browser will always show an alert The certificate is not correct when it connects to this server. This is despite the fact that transmission is secure.

Overview: PRTG web interface security options

Under Setup | System Administration | User Interface on the PRTG core server system, you can select different security options that specify how users connect to the PRTG web interface. The following table will give you an overview of the user's experience for the different options.

Disable SSLNone (passwords and account information are not encrypted. Use only in secure LANs/VPNs. Do not use for PRTG installations that are publicly visible on the internet.)User sees no warningUnder PRTG Web Server, set TCP Port for PRTG Web Server to Unsecure HTTP server (port 80)
PRTG default SSL certificateYes (unverified)User sees a certificate warningUnder PRTG Web Server, set TCP Port for PRTG Web Server to Secure HTTPS server (port 443)
InstantSSL Free Trial certificate (90 days) - paid option for longer use availableYes (Class 1)User sees no warning - Specialty: The certificate can even be requested for a private IP address so the user sees no warning when using a private IP address to access the PRTG web interfaceUnder PRTG Web Server, set TCP Port for PRTG Web Server to Secure HTTPS server and install an InstantSSL Free Trial certificate

Set up your own Certification Authority

If you only access your PRTG server from within your own domain, you can create your own free trusted certificate, by setting up your own Certification Authority (CA).

This CA can handout certificates that will be trusted within your own network. You have to make sure that your users can contact and trust the CA.

See this Microsoft article on how to install your own CA http://technet.microsoft.com/en-us/library/cc756120(WS.10).aspx
