Every event becomes evidence.

No vague “completed” state. NiaSign tells the exact story: who opened it, who signed it, what changed, and when the record sealed.

FOR PLATFORMS

Bring signing inside your own product.

Partner APIs, embedded sessions, and a signer flow that feels native instead of bolted on.

EMBED.JS
// create an embedded signing session
const session = await niasign.sessions.create({
  document: "msa.pdf",
  signer: { name: "Aanya Mehta", email: "aanya@example.com" },
  mode: "embedded",
  evidence: "sealed_audit_trail"
});

SECURITY & COMPLIANCE

Easy for signers. Hard for tampering.

The friendly flow sits on infrastructure that is certified, encrypted, and independently audited — so security reviews end in yes.

CERTIFIED
SOC 2 Type II

Independently audited controls, re-tested every year.

LEGAL
ESIGN · UETA · eIDAS

Signatures that hold up in US and EU courts.

ENCRYPTED
AES-256 + TLS 1.3

Encrypted at rest and in transit, keys rotated on schedule.

VERIFIABLE
Tamper-evident hashing

Any change after sealing breaks verification — visibly.

FAIR QUESTIONS

Asked. Answered. Sealed.

No. Signers get one link and sign from any device — no download, no password, no account. Identity is verified inside the flow itself.

Yes. Signatures satisfy ESIGN and UETA in the US and eIDAS in the EU — and every one ships with a sealed audit certificate as evidence.

Every event — who opened the document, verified identity, signed, and when — locked to a cryptographic hash of the final file. If anything changes later, verification fails visibly.

Yes. embed.js drops a native-feeling signing session into your UI, and the partner API handles envelopes, webhooks, and evidence on the Platform plan.

They're yours. Export every document and its audit certificate at any time — sealed records stay verifiable even outside NiaSign.
