API keys in chat threads. Passwords in email. Files containing PII or financial data in e-mails. Each one sits there forever — forwarded, screenshotted, leaked. Konfidant replaces them with encrypted, one-time links that self-destruct after the first view.

One-time encrypted download link — expires in 24h

The problem your team has right now: API keys sitting in Slack. Database credentials in email threads. PII in Jira tickets. Financial reports in e-mails. None of it expires. All of it can be forwarded, screenshotted, or exfiltrated. Every plaintext secret in a chat thread is a compliance incident — and the breach that triggers it won't warn you first.
How it works
Paste text or upload a file. Konfidant encrypts it immediately using envelope encryption — plaintext never touches our servers.
Get a one-time access link. Send it over Slack, Microsoft Teams, email, or any channel. The link carries no readable data — only a wrapped token.
The recipient opens it once. The token is consumed, the data is wiped, and the link is burned. No copies. No history. No exposure.
Features
Whether you're in legal, infosec, DevOps, or HR — Konfidant gives you the controls to share securely without changing your workflow.
Content is cryptographically destroyed after the first view. The encryption token is single-use — subsequent requests return 410 Gone.
Our transit encryption engine generates a unique DEK per share. The plaintext key never persists.
Set expiry from 1 hour to 30 days. Wrapped tokens expire independently — even if the link is never opened, the data disappears.
Choose where your encrypted data lives. EU and US servers are isolated — meet your data residency requirements.
Serve share links from your own domain — share.yourcompany.com — with automatic SSL via Cloudflare.
For compliance-critical teams: log who received what, when it was opened, and confirm destruction. Full chain of custody.
Security architecture
Konfidant is architected so that we never hold your plaintext data. Encryption happens before storage. Decryption happens at retrieval — and only once. Not even Konfidant can read what you shared.
