'die Sicherheit' and 'die Klarheit' can both have to do with knowledge and understanding. Here, 'Sicherheit' means being certain that something is true or reliable. 'Klarheit' means that something is understandable, unambiguous, or internally resolved. The words can be confused when talking about decisions or information. If you want to emphasize that there is no longer any doubt, 'Sicherheit' fits. If you want to emphasize that something is understandable or well organized, 'Klarheit' fits.
