Built for the documents your organization can't afford to mishandle

SecureSafe Postbox is built around the full document dispatch lifecycle – from legally compliant large-scale sending to encrypted long-term archiving. Every capability is designed to give your organization the legal standing, operational control, and compliance infrastructure your document workflows demand.

Legal confidence, built into every send

ECJ-compliant document dispatch, by default

Every document dispatched through SecureSafe Postbox meets the ECJ's legal requirements for a permanent data carrier, giving your organization the legal standing it needs for regulated document communication, without any additional steps or configuration.

Large-scale, secure dispatch

Scales with your organization, not against it

Proof of delivery, every time

Delivery confirmation & read receipts for every send

Receive confirmation when documents are delivered and opened. Every dispatch is documented, so no more chasing, uncertainty, and reliance on recipients to confirm receipt – your organization always has proof of delivery when it matters.

Store it once. Trust it long-term

Encrypted long-term archiving for compliance-critical documents

Keep contracts, records, and compliance-critical documents in a structured encrypted archive, protected by zero-knowledge architecture and accessible only to those you authorise. Everything your organization needs to store securely, for as long as you need it.

Security
