Why is a Combo DSC (Signing + Encryption) required for e-Tendering?

Government tender portals require the Signing certificate to authenticate your tender submission and the Encryption certificate to encrypt your commercial bid data so that only the tender evaluation committee can decrypt it on the opening date.

Which portals accept Care4Sign Class 3 Combo DSC?

Care4Sign is a licensed CA under CCA, Govt. of India. Our certificates are 100% accepted on Central Public Procurement Portal (CPPP), GeM (Government e-Marketplace), IREPS (Indian Railways), Coal India, IOCL, ONGC, NTPC, and all State e-Procurement portals.

Can an Individual apply for Tender DSC or is Organisation DSC required?

Proprietors can bid using a Class 3 Individual Combo DSC. However, for Companies, Partnerships, and LLPs, government portals strictly require a Class 3 Organisation Combo DSC issued in the name of the authorized bidder with the company name.
