IRON ID EnterpriseThe Sign SDK is sold separately from the IRON ID Platform: integrated into your own applications, through enterprise sales, on quotation. It is not included in Silicon.
What is IRON ID Silver?
The Sign SDK: embed trusted digital signing into your own products.
The Sign SDK lets your applications send documents for signature, collect signatures in an embedded flow, and get back a sealed document: PAdES B-LTA, a timestamp per signature, and an evidence bundle.
Signers are IRON ID identities: accounts your organization controls, protected by multi-factor authentication. A partner, a client or a court checks document integrity and its timestamp in any standard PDF reader and on the public verification page, without IRON ID.

Years later
Day 0, year 2, year 10.
A signature is only useful if it can still be checked when someone finally asks. That is where most signed PDFs quietly fail.

Levels
Precise about the level, on purpose.
Signature levels are legal categories. The SDK states exactly which one it provides, and what the next ones depend on.
Simple electronic signatureAny signature at the standard level.At launch
Advanced electronic signatureRequires the exclusive control model to be validated by a lawyer.Under legal review
Qualified electronic signatureRequires a qualified trust service provider and a qualified device; not planned for the first version.Not in V1
Legal value is not claimed beyond the level actually provided. When the advanced level is validated, this table changes, not the marketing.

FAQ
Questions buyers ask first.
Is the Silver Sign SDK part of the IRON ID Platform?
No. It is a separate enterprise product for embedding signing into your own applications, priced on quotation.
Which signature level does it provide?
The simple electronic signature level at launch. Advanced and qualified levels require legal validation and a qualified provider, and are not claimed until in place.
Can a partner without IRON ID verify a signed document?
Document integrity and its timestamp check in any standard PDF reader and on the public verification page. Automatic recognition of the signer in Acrobat requires a certificate issued by a CA on Adobe's AATL (planned).
When is the Silver Sign SDK available?
Coming soon. It is specified and follows the sharing milestone; enterprise prospects can start the technical discussion now.
How is it priced?
On quotation: envelope volumes, integration scope, signature levels required and support level.
