Collaboration with "Karamba Security" for cybersecurity of AGL

Went through the official page of AGL, where it was mentioned the collaboration on Karamba Security and AGL for cybersecurity domain. Can you please let me know does the improvements or security enhancements provided by Karamba Security are open source and directly supported by AGL. And please also let me know if the cybersecurity provided by AGL is based on which standards, say for example ISO/SAE 21434. Do they (AGL) provide every security implications by default from their side?
