TOS Precheck

Overview

You can run this procedure whenever you want to check TOS configurations without affecting TOS performance.

This procedure identifies misconfigurations that might interfere with TOS. After the procedure finishes, you send the output to Tufin Support for assessment.

Tufin Support will analyze the output and contact you with their conclusions and any recommended actions.
