Syndis Share: Send sensitive files, leave nothing behind
End-to-end encrypted file transfers. Files are sealed in your browser, opened only by your recipient, and removed when the link expires.
Email was never built for this
.
A contract, a payroll file or a security report sent as an attachment lives on in inboxes, sent folders and backups for years. Most file sharing tools hold the keys to your files, so their breach becomes yours. Syndis Share is built the other way round: the file is encrypted before it leaves you, and it is gone when the job is done.
Hardened Workflow
Three steps. No keys left with us
The link is the key. Treat it like a password: send it directly to your recipient, add a password or identity check for anything confidential, and keep the expiry short.
Upload
Your browser encrypts the file, its name and its type before anything leaves your device. Each transfer gets its own key.
Set the rules
Choose who can open it and for how long: password, Auðkenni verification, expiry date and download limit.
Share the link
The key travels inside the link, after the # symbol. Browsers never send that part to our servers, so only your recipient's browser can unlock the file.
Frequently Asked Questions
Common questions about encryption architecture, data residency, file limits, and enterprise deployment.
All files are stored in sovereign Nordic data centers located in the European Union. Your data is protected by strict European privacy standards and is never subject to foreign surveillance statutes such as the US CLOUD Act.
No. Syndis Share is engineered specifically for large enterprise transfers, accommodating multi-gigabyte forensic disk images, database archives, and virtual machines with automated chunking and resumable uploads.
The recipient confirms their identity with the authentication method chosen by the sender (electronic ID, SSO, or a one-time-code sent via SMS)
Syndis Share provides end-to-end zero-knowledge encryption, strict access governance, and immutable audit logs. Detailed access reports can be exported directly for formal regulatory audits and incident reviews.
Most organizations are operational within 24 hours. Syndis Share integrates directly with existing enterprise Single Sign-On (SSO) providers and allows immediate configuration of organizational security policies.
