Online Certificaat Status Protocol:

A major software vendor has released a beta version of their browser that will have automatic certifcate revocation checking as a default option

This new checking protocol will maximize the speed of checking the status of thawte certificates and will minimize the possibilities of online fraud as invalid certificates and companies will immediately be exposed to the end customer

thawte has invested significanltly in the infrastructure which can support OCSP - something not all CAs will be able to provide and support.
