Lightning-fast ID verification for receiving and sending documents.
Registered digital delivery, with verifiable proof of receipt.
Send confidential documents and know exactly when and where they were received. The recipient is notified by email with a secure link to the delivery. Every delivery is end-to-end encrypted and produces a verifiable certificate. Add optional identity verification and you know not just that it was delivered, but to whom and whether it was read. If the recipient ignores it, you receive a Statement of Attempts. Just like physical registered mail, but digital.
Upload and send
Drop your files, choose the security level (email, SMS or identity check) and send. End-to-end encrypted and EU-hosted.
Recipient opens securely
The recipient verifies and opens the documents in a secure portal. Time, location and device are recorded independently.
Verifiable certificate
You receive a verifiable piece of evidence: when and where it was received, and with ID verification also by whom. Ready to submit in proceedings.
Smart KYC. Compliance without complexity.
Send an invitation and your client verifies themselves remotely: an ID scan, a live biometric face check and a short questionnaire, on their own phone. The result is known within seconds. You know exactly who you are dealing with and capture your client due diligence for AML/KYC.

Send an invitation
Invite your client in one click, by email or link. No account or install required.
Verify remotely
The client scans their ID, completes a live biometric face check and fills in the questionnaire. All on their own phone.
Analysis in 6 seconds
The check is assessed automatically in seconds. You receive a complete report for your client due diligence.
What the check covers
- Identity document (passport, ID, driving licence)
- Live biometric face match
- Liveness check (anti-spoofing)
- PEP screening (politically exposed persons)
- Sanctions and watchlist screening
- Adverse media screening
- Age verification
- Document authenticity check
A hit is never waved through. You assess it yourself and record the decision, with reviewer and timestamp. Together with the PEP self-declaration and the stated source of funds, this forms a recorded client due diligence file you can produce on request.
One secure space for the whole case.
Communicate and exchange documents with your client or counterparty inside a sealed workspace per case. End-to-end encrypted, with every action logged in a complete audit trail you can present as evidence at any time.

When is registered digital delivery needed?
Legal notices, confidential contracts, financial filings: anywhere proof of receipt is essential.

Legal notices
Termination letters, summonses, formal demands. Whether the recipient verifies (strong, verifiably documented evidence) or ignores (Statement of Attempts), proof is always obtained, just like physical registered mail.
Notarial deeds
Property transfers, wills, deeds of separation.
Confidential contracts
NDAs, M&A documents, shareholder agreements.
Financial reporting
Annual accounts, VAT filings, due-diligence files.
Medical records
Patient handovers, specialist referrals, medical reports.
Privacy-sensitive documents
GDPR-relevant personal data, HR records, payroll documents.
The advantages of registered digital delivery over regular email
Ordinary email is encrypted in transit at best, and your provider can simply read the content. TransferGuard is end-to-end encrypted, and with an access code even zero-knowledge: no one can read along, not even us. On top of that you prove who received what, your data stays in the EU, and you send straight from your own Outlook.

Genuinely confidential
Only the recipient can read it.
SecuredEnd-to-end encrypted. With an access code even zero-knowledge, so not even we can read it.
Regular email: Encrypted in transit at best. Your provider can read along and in the inbox everything sits unprotected.

Get a complete verifiable evidence file of delivery and receipt
Every registered file transfer generates a certified audit trail. See what Certified Delivery & Verified Identity users get.

Proof of Delivery
Certified evidence of file transmission with timestamp and recipient ID.
Full Audit Trail
IP address, timestamp, and device info logged for every download.
Identity-Verified Delivery
Biometric ID verification proves exactly who received your documents. Strong circumstantial evidence for civil proceedings.
Seven layers of evidence.
Every transfer is backed by verifiable security, standard.
Identity verification + biometric facial verification (passport, ID card, driver's license)
Who received it, proven.
Recipients verify their identity with an official government-issued document (passport, ID card or driver's license) and a live selfie with biometric facial verification before gaining access.
Recipients verify their identity with an official government-issued document (passport, ID card or driver's license) and a live selfie with biometric facial verification before gaining access.
The recipient confirms access via a one-time SMS code on their verified phone number: proof that the right person received the files.
An independent party (an external time-stamping authority) records the exact moment of delivery with an independent verified timestamp. Not TransferGuard itself, but this external party guarantees the time. Years later, a judge, lawyer or auditor can cryptographically verify the timestamp without having to trust TransferGuard.
Every file receives a unique SHA-256 fingerprint. Any modification breaks the verification.
IP address, geolocation, browser, OS and device fingerprint, all recorded in the audit report.
We record when the document was rendered in the viewer, how long it stayed visible, and to what scroll depth. An integrity score (0-1) distinguishes human reading from bot or spider activity. Stronger proof than a manual "I confirm" click. Note: Open Detection only works for transfers sent without end-to-end encryption, with true end-to-end (access code) the viewer cannot render the content, so the moment of reading cannot be measured.
Every delivery generates a comprehensive audit report with cryptographic integrity checks, bringing all previous layers together into a single, verifiable piece of evidence.
We integrate into your existing workflow.
