Is CCAV enough against 99% of ransomwares?

Hi everyone,

I would like to ask about CCAV with default sandbox settings
I'm not a fan of highly restricted/untrusted rules, I prefer partially limited (CF& CIS) or a bit higher than partial but less than highly restricted (CCAV)

In this case of CCAV, can it protect agaisnt most ransomwares which are not able to bypass CCAV's sandbox?

thank you
