Certificates and Certificate Authorities

Nessus includes the following defaults:

  • The default Nessus SSL certificate and key, which is made up of two files: servercert.pem and serverkey.pem.

  • A Nessus certificate authority (CA), which signs the default Nessus SSL certificate. The CA is made up of two files: cacert.pem and cakey.pem.

However, you may want to upload your own certificates or CAs for advanced configurations or to resolve scanning issues. For more information, see:
