It is probably the SSL certificate on the Tenable SC is not trusted by QRadar. If QR cannot validate the certificate you will need to put a copy in correct format in /opt/qradar/config/trusted_certificates. There is a script called getcert.sh or something like that in the /opt/qradar/bin directory which does it for you. Once the file is in the directory, named correctly and is NOT zero bytes, I use certutil -print -file filename to check the format is correct for java. If you have offline CAs in the chain, you will need them in the file as well and in the proper order. This is all just normal java certificate stuff. It has to trust the cert or it will not work.
For the Tenable APP, this has to be done on wherever the app is running. To pull vulnerability data into QR, you will need it on the device doing the pulling, usually a Console, EP or EC.

Hello all,
We have technical dificulties with implementing Tenable.sc (T.sc) with IBM QRarad SIEM (SIEM). We installed on SIEM Tenable.sc application via IBM QRadar Assistant.
We are running IBM QRadar 7.4.3 FixPack 4 (Build 20211113154131) with interim fix IF02 applied on-prem. We are running T.sc at Version: 5.20.1 Server Build ID: 20220122051145
We are using latest Tenable app for Qradar v7.4.1 FP2+ in Version 4.1.0 from QRadar Assistant.
We are trying to set it up by this step by step documentation: https://docs.tenable.com/integrations/IBM/QRadar/Content/Tenable.scConfiguration.htm
We have set Configure Rule-Based Scanning a Configure Right-Click Scanning, acces keys, tokens, certs and so on. In T.sc we have user QRadar with Security Analyst rights and API key for Tenable app and basic scan with name Qradar_Scan.
When we try test connection and save config, we have an error: "Please enter valid Address or configure valid proxy settings or verify SSL certificate."
It does not matter if we try Enable SSL or not, in address is used IP address or DNS name. Always same error.
Any idea what is wrong? Does anyone have experience with QRadar and Tenable.sc integration?
Thanks in advance.
