OCSP Service

Checks the validity of certificates in real-time
This service allows institutions to check the status of their customers’ certificates by transferring certificate information to the yessign Certification Center, which verifies the validity of the certificates and sends the information back to the institutions in real-time.
Because an institution can check the status of not only yessign certificates but also
those issued by other CAs, the risk of certification incidents happening can be minimized.
