VSign

What VSign does

VSign (operated by VERASYS Technologies Pvt. Ltd.) is a Licensed Certifying Authority under India's Controller of Certifying Authorities (CCA), Ministry of IT, headquartered in Mumbai with 51-100 employees. The company issues Class 3 Digital Signature Certificates (DSCs) for individuals and organizations, provides eSign APIs and the SignPDF consumer portal for paperless electronic signatures authenticated via Aadhaar OTP, PAN, biometric fingerprint, or biometric face-match, and offers HSM-based Document Signers for high-security enterprise use cases including banking, ERP/SAP integration, and UIDAI Aadhaar KYC.

The underlying technology stack combines X.509 digital certificates, PKI infrastructure supporting PFX and HSM-based document signing, USB token authentication, and Aadhaar-based eKYC, all integrated with Indian regulatory platforms (UIDAI, NSDL, MCA, DGFT, Income Tax, GST, TRACES, EPFO, and multiple e-procurement portals). The Verasys API Stack extends the platform into adjacent verification services spanning bank accounts, PAN/GSTIN, passport, voter ID, MCA company details, and telecom. The company is ISO 27001 and PCI-DSS certified.

VSign makes money through a fragmented revenue model: one-time DSC issuance fees (basic L1 package at 1,400 INR, ~$17, with USB token and support tiers up to L4), usage-based API call pricing on eSign and verification APIs, transaction fees on eStamp services, USB token sales, and performance-based commissions to its 30,000+ RA partner network. Distribution combines direct self-serve online portals (dsc.vsign.in, signpdf.vsign.in, esign.verasys.in), an OEM/API channel for ASPs embedding eSign, and a long-tail channel partner network that has accumulated 2.5M+ end customers across India spanning individual tax/GST filers, banks (Axis Bank, Bank of Baroda), government undertakings, and SMBs.
