Thank you @sunate_h for posting question.

I am not sure how OCSP/CRL check is related to Zoom. To my knowledge there is no correlation. Could you please provide more details?

Regarding what policy is permitting OCSP from your clients, could you please navigate to: Monitor > Traffic > Use following Application filter: ( app eq ocsp ), then you can find what policy is getting hit.

By default Firewall itself is using management interface for certificate validation. The service is called: CRL Status.

Kind Regards

Pavel
