Cesign is a cloud-based digital signature platform built on the principle of self-explanatory user interfaces — modern enough that nobody needs training, rigorous enough that the audit trail holds up to regulatory scrutiny.
A digital signature is more than an image of a handwritten name. It is a cryptographic proof — a verifiable record that a specific person, at a specific time, with a specific intent, attached themselves to a specific document. Cesign handles the full chain: identity verification at signing, cryptographic binding to the document, immutable audit trail, and a manifestation that satisfies a regulator, a court, or a finance auditor.
The product is sold against the global standard for electronic signature trust — not as a quick alternative to wet-ink signing, but as the modern equivalent to a notarised, witnessed, and archived original. Every signature is bound to its document by a unique cryptographic ID. Every step is timestamped, IP-stamped, and logged. The signature record cannot be excised, copied, or transferred. That is the difference between an electronic signature and a digital one.
The capabilities below are part of every Cesign signature, regardless of plan tier. The only thing that changes between tiers is volume, team features, and the regulated/CLM add-ons.
No USB tokens, no physical key management, no expiry surprises. Cloud-issued certificates with cryptographic equivalence to traditional PKI tokens, but without the operational burden.
For India, integrate directly with the licensed certifying authority under the IT Act. Sign with Aadhaar OTP. Meets CCA guidelines. Tailor-made for Indian businesses but optional everywhere else.
Build a document inside Cesign with the editing experience of Microsoft Word, then send it for signature without uploading or exporting. The compose-to-send loop is one continuous workflow.
Drag the signature box anywhere on the document. Add fillable fields — date, checkbox, drop down, initials — for the recipient to complete before signing. The signer's view matches your specification exactly.
Every action on a document — sent, viewed, signed, rejected, commented — is logged with timestamp, IP, and user identity. The audit trail is immutable, exportable, and includes a certificate of completion.
Native iOS and Android apps for signers who do not want to use a browser. Same audit trail, same cryptographic binding, full offline draft support with sync on reconnect.
Anyone — sender, signer, third party, auditor — can upload a Cesign-signed document to the validator and get an instant verdict on whether it is authentic and unmodified.
Every uploaded document is scanned for malicious content before processing. Compromised PDFs and infected attachments are rejected at the door, not after they reach a signer.
India operates one of the most sophisticated digital identity infrastructures in the world. Cesign integrates directly with it — the Aadhaar authentication service operated by the licensed certifying authority under the Information Technology Act.
The result: Indian businesses can sign documents with the same legal weight as a notarised wet-ink signature, in seconds, from a mobile phone, with the regulatory framework already on their side.
For everyone else, multi-factor email authentication is the default, with optional integrations to country-specific certifying authorities as customers require them.
Document arrives at signer. Email notification with secure link, OTP-protected.
Signer opens, reviews, accepts. Reads document, fills any required fields, confirms intent to sign.
Aadhaar OTP requested. Signer enters Aadhaar number; OTP sent to registered mobile.
Cryptographic binding. Signature applied with timestamp, identity from Aadhaar authority, document hash.
Audit trail closed. Both parties receive completion certificate. Document is now legally enforceable.
