Signature vs. Seal — what's the difference?
✍️Electronic Signature
Represents a person. "I, Maria, agree to this." Requires individual PIN confirmation per document.
🏛️Electronic Seal (e-Seal)
Represents the organization. "This document comes from Acme GmbH." Can be applied automatically — no human interaction per document.
Both are eIDAS-defined. Both are cryptographic. The seal is the company's voice.

What an e-Seal proves — and why it matters

Every time your company sends a document — an invoice, a certificate, a report — the recipient has two questions: "Did this really come from them?" and "Has it been changed?" An e-Seal answers both, cryptographically.

🏢

Origin

This document was issued by a verified legal entity. The seal certificate is linked to the company's identity — anchored to DUNS and business registry.

🔒

Integrity

The document has not been altered since the seal was applied. Any change — even a single character — breaks the seal and is immediately detectable.

🕐

Time

A qualified timestamp records exactly when the seal was applied. The document is provably locked in time — critical for invoices, compliance records, and legal evidence.

Why IdentiGate e-Seal

Fully automated via API

No human clicks per document. Your ERP, CRM, or invoicing system calls our API — the seal is applied instantly. Thousands of documents per hour. Zero manual work.

🏢

Linked to verified company identity

The seal certificate is bound to your IdentiGate Company Identity — verified against D&B DUNS and business registries. Not just any certificate — a certificate that chains back to a proven legal entity.

Combine seal + personal signature

Use the seal to prove the document comes from the company. Then have an authorized person sign it individually. The document now has both: organizational origin + personal commitment.

🛡️

Anti-fraud protection

Sealed documents cannot be forged. A fake invoice claiming to come from your company? Recipients verify the seal in one click — if it's missing or broken, they know it's fraudulent.

☁️

Cloud-hosted, no hardware

The seal certificate is hosted in our cloud-based HSM. No physical USB tokens, no on-premises hardware. Secure, always available, and managed by IdentiGate.

What companies seal

Anything your company issues — sealed automatically

🧾

Invoices & financial documents

Seal every invoice your ERP generates. Recipients can verify instantly that it came from your company and hasn't been tampered with. Reduces invoice fraud risk to near zero.

📜

Certificates & diplomas

Educational institutions, training providers, certification bodies — seal credentials so they're machine-verifiable and impossible to forge.

📊

Reports & compliance records

Audit reports, lab results, compliance attestations — seal them at the moment of generation. The timestamp proves when they were created. The seal proves they haven't changed.

📦

Shipping & logistics documents

Bills of lading, packing lists, customs declarations — seal them at scale. The carrier's seal + the driver's signature = complete provable chain.

📧

Outgoing communications

Official letters, policy documents, terms updates — seal them to prove they're genuine. Protect against phishing and impersonation of your company's communications.

💊

Pharmaceutical & medical records

Seal prescriptions, test results, batch certifications. Prove origin and integrity for regulatory compliance and patient safety.

How automated sealing works

Your system generates a document. Our API seals it.

1

Document generated

Your ERP, CRM, or system creates a document — invoice, report, certificate, letter. Business as usual. No changes to your existing workflow.

2

API call to IdentiGate

Your system sends the document (or its hash) to the IdentiGate Seal API. One REST call. No user interaction needed — this is machine-to-machine.

3

Seal + timestamp applied

IdentiGate applies the company's e-Seal certificate (stored in cloud HSM) and a qualified timestamp. The seal cryptographically binds the document to the company's verified identity.

4

Sealed document returned ✓

Your system receives the sealed document — ready to send, archive, or publish. Any recipient can verify the seal with standard tools. Tamper-evident forever.

Zero human interaction per document. The seal is applied by your system automatically. No one needs to click, review, or enter a PIN. The company's seal certificate handles it.
Seal + signature — together

Company origin + personal commitment. On one document.

The most powerful documents carry both: a company seal that proves origin, and a personal signature that proves an authorized individual approved it.

With IdentiGate, both are on one platform. The seal is applied automatically when the document is generated. The personal AdES signature is added when the authorized person confirms with PIN2. Together: the company issued it, and this specific person approved it.

Both the seal and the signature chain back to verified identities — company via DUNS, person via passport. Complete provability.
