Trust cues
When work is confidential
A sealed workspace replaces the file chase.
Dossira is a secure workspace for sharing confidential files with the right people. Instead of sending attachments, re-sharing links, or relying on shared drives, we keep distribution in one sealed room—so we know who has access, where the documents are, and what the current version is.
What usually happens
- Confidential files end up in many inboxes, shared drives, devices, and backups.
- Nobody is sure how many copies exist, or where they are stored.
- Attachments and links get forwarded to the wrong place.
- The current version becomes a guess.
- Access is hard to revoke once the work moves on.
What changes with Dossira
- One sealed workspace per case, pack, or process.
- Members and guests enter with passkeys, not passwords.
- Comments and decisions stay attached to the file.
- A clear record of access and key actions.
Keep files and decisions together.
Comments stay attached. The trail stays clean.
