A signed PDF is not a contract. A click-wrap audit log is not evidence of identity. In 2026, cross-border transactions demand cryptographic proof of the signer ā not just a typed name and an IP address.
Global e-signature adoption accelerated from 2020 and never returned to baseline. Every contract, approval, NDA, and procurement is now routinely signed digitally ā across all industries, all geographies, all counterparty types.
The plumbing ā the large generation of click-wrap e-sign platforms ā scaled with the volume. But the identity layer underneath did not. Most e-signatures still anchor on "someone accessed this email and typed a name", a standard that predates deepfakes, synthetic identities, and coordinated business-email-compromise operations.
eIDAS AdES is the EU legal standard that closes this gap ā requiring cryptographic uniqueness, signer control, and tamper detection. IdentiGate's AdES signatures are generated by a passport-verified identity, not a typed name on a PDF.
High-value cross-border transactions fail at two points ā the identity of the counterparty, and the evidentiary weight of the signature. These are the industries where both failures compound.
Cross-border power of attorney, shareholder resolutions, notarial acts. The audit trail isn't for you ā it's for the counterparty's lawyer, the regulator, or the court. AdES is the baseline; anything less loses at trial.
Multi-million agreements with suppliers you've never met, signed by people whose authority you can't verify. Every disputed deliverable becomes a "who signed this?" investigation. Passport-anchored AdES ends the ambiguity at contract time.
Loan agreements, margin calls, investment mandates, derivative confirmations. Every one is a regulated document. DORA requires phishing-resistant MFA for authentication ā eIDAS AdES-equivalent evidence is the next logical step for the signature itself.
Legacy e-signature platforms were designed for convenience, not assurance. They accelerated signing ā at the cost of making signer identity provable only through the ceremony of the platform itself, not through cryptographic evidence. AdES and passport-anchored identity change the default.
Most businesses use one of three signing approaches today. Each solves part of the problem. IdentiGate is the first to close both the identity and the signature assurance gap, at a price between SES and QES, using the passport that already exists in the signer's pocket.

AdES sits between SES (no identity assurance) and QES (requires a Qualified Trust Service Provider). For the vast majority of B2B transactions, AdES is sufficient, legally strong, and far cheaper than QES. QES is on our roadmap via QTSP certification in Q4 2027 ā for now, AdES covers everything your cross-border business runs on.
An IdentiGate AdES signature is not a rendered image of a name. It is a tamper-evident cryptographic bundle ā the document, bound to five independent proofs, sealed together so any later change is immediately detectable.
This is why AdES holds up in court when SES does not ā and why cross-border commerce increasingly requires it.
Your counterparty's e-signature audit log tells you an email account authenticated to their platform. It does not tell you which human pressed the button ā or whether that human was their CFO, their assistant, or someone who gained access to the email. When a deal disputes, this ambiguity is the crack the lawyer walks through.
Passport-anchored AdES cryptographically binds the signature to a biometrically verified person. The dispute becomes a forensic exercise, not an argument.
An SES signature valid in the Netherlands might not carry the same weight in Turkey. A QES signature issued by a Dutch QTSP might not be recognised automatically in Brazil. eIDAS provides harmonised EU recognition; ESIGN covers the US; beyond that, you are in bilateral-treaty territory.
IdentiGate's AdES signatures work where eIDAS is recognised. Coupled with the passport-verified identity of the signer, they provide the strongest globally-portable signature evidence available outside a QES certificate.
A typical B2B transaction has three or more signers ā the contracting parties, a witness, a guarantor, a notary. Legacy platforms handle this by collecting signatures sequentially, each with their own identity assurance level. Each signature is only as strong as its weakest link in the chain.
IdentiGate issues individual AdES signatures for each party, all chained into one evidence record. Every signature is equally strong. The evidence chain is verifiable by any party, in any jurisdiction that recognises eIDAS or ESIGN.
Qualified Electronic Signatures (QES) are the gold standard in EU law ā equivalent to a handwritten signature. But they cost ā¬2ā5 each and require a QTSP certificate per signer. For the 92% of B2B documents that don't legally require QES, this is overkill.
AdES is legally sufficient for the vast majority of commercial contracts. IdentiGate makes rigorous signing economically viable at the scale cross-border commerce actually runs at ā see the AdES product page for current pricing.
Each capability below solves a specific moment in the signing lifecycle ā from the first verified signer, through multi-party contracts, to the evidence chain that stands up in court three years later. Deployable today, built on our existing products.
An eIDAS Article 26 signature ā cryptographically unique, biometrically bound to the signer's verified passport. Recognised across all 27 EU member states, enforceable under ESIGN/UETA in the US.
An acquisition agreement needs five signatures. With multi-party AdES, every signer brings their own verified identity and cryptographic chain entry ā five signatures, five independent proofs, no weak links.
Supply-chain attestations, board approvals, regulatory filings need an organisational signature. A cryptographic e-Seal makes "signed by the company" a verifiable fact, not a placeholder.
Two parties dispute when a document was signed. A qualified timestamp ā issued by a trusted time source at the moment of the signature ā ends the dispute with cryptographically signed proof.
Three years later, the case goes to court. Who opened the document, when, which version was viewed, who annotated page 7? A cryptographic evidence chain answers every question with tamper-evident proof.
500 customer confirmations before month close. 2,000 invoice signatures by 17:00 for quarterly close. Batch operations with per-document AdES ā each signature still cryptographic, each identity still verified.
The industry isn't here yet. Our architecture already is.
Certain regulated filings, cross-border enforceability scenarios, national-law requirements need QES ā the legal equivalent of a handwritten signature under eIDAS.
An AI agent signs a procurement order on behalf of a human authorised signatory. The signature must carry a cryptographic delegation chain back to the verified human.
Proof the signer has signing authority for this class of contract ā but not their title, role, or department. Selective disclosure on top of AdES.
For legal, contract, procurement, finance, and platform teams that want AdES inside their existing CLM, CRM, or workflow. You keep your contract lifecycle management, approval routing, and procurement workflow ā we add the eIDAS-compliant signature primitive underneath. Includes dedicated CLM vendor integrations for DocuSign, ContractPodAI, Ironclad, and custom platforms.
Your engineering team integrates via REST API; your IAM layer consumes the X.509 certificate via SAML, OIDC, or SCIM. Scales from single-document signing to cross-border enterprise volume where multi-jurisdiction enforceability and audit evidence are hard requirements.
For legal teams, SMEs, freelancers, and cross-border contracts that need AdES signing without engineering work. Upload your document, invite signers (worldwide ā 179 NFC countries plus document route), each signer verifies via passport and signs with eIDAS AdES ā court-ready anywhere. The signed document comes back to you with full audit trail.
Especially powerful for USA ā EU ā Asia ā Africa contracts where most e-signature platforms produce only Simple Electronic Signatures (SES) ā basically "click to agree" with weak dispute-resolution weight. IdentiGate replaces click-wrap with proof that a passport-verified person signed at a specific time, from a specific device.
Full pricing, volume tiers, and enterprise terms live on the product pages. Integration fee scoped per engagement ā we quote after a short discovery call.
20 minutes. A real contract. A real signer with a real passport. See the AdES signature generated in the Secure Enclave, chained into tamper-evident evidence, and verifiable on any standards-compliant validator ā including the European Commission's own DSS tool.
