Class 3 Document Signer Certificate (HSM Based)
Running an organisation today means signing hundreds, sometimes thousands, of documents every single month — invoices, contracts, offer letters, policies, and approvals. Doing this manually is slow, error-prone, and simply not practical at scale. This is exactly the problem a Class 3 Document Signer Certificate (HSM Based) is built to solve.
Unlike a personal Digital Signature Certificate that is issued to one individual, a Document Signer Certificate is issued in the name of your organisation and installed on a Hardware Security Module (HSM), allowing your systems and applications to sign large volumes of documents automatically, securely, and without manual intervention. If your organisation needs to authenticate bulk digital documents while staying fully compliant with Indian law, this certificate is designed for exactly that purpose.
We help organisations across India obtain their Class 3 Document Signer Certificate (HSM Based) through a completely online, guided, and Pan India process.

What Is a Class 3 Document Signer Certificate (HSM Based)?
A Class 3 Document Signer Certificate is a high-assurance digital certificate issued to an organisation, not to an individual, for the purpose of digitally signing documents in bulk through automated systems and servers.
The "HSM Based" part refers to how the certificate's private key is stored. Instead of being kept in a file (as with a Class 2 Document Signer Certificate, which uses a .PFX format), the Class 3 version requires the private key to be generated and stored inside a Hardware Security Module. This is a dedicated, tamper-resistant hardware device where the private key remains locked at all times and never leaves the device, even during the signing process.
This makes the Class 3 Document Signer Certificate the highest level of assurance available for organisational document signing in India, and it is the standard preferred by banks, government departments, insurance companies, and large enterprises that handle sensitive or high-volume digital records.
Important to note: This certificate is meant strictly for organisations, companies, government bodies, and institutions. It is not issued to individuals, and it is not meant for personal use such as income tax filing or personal MCA/ROC filings — those require an individual Class 3 DSC instead.
