The toolkit
What the price covers.
Email and file shares
Scans every email and attachment before it sends, proposes the removals, and catches the wrong recipient. Redact, don't block.
Bulk external sharing
Days of manual document review become one secure send. Hundreds of files at once, and every finding cites the rule behind it.
AI on real matters
The model connects to a vault and reads a synthetic twin of the file. Every identifier is swapped for a stand-in that stays consistent across documents, and only your firm can map it back.

Our exposure is worse than the client believes.
Already have a security team? Keep it. We govern the people you let in, on the tools you already use.
Why teams buy this
Enterprise liability.
Consumer-grade controls.
You hold the same data, and the same duties, as a Fortune 500, with none of the budget. Most leaks are not break-ins. They are an authorized person sending something they should not, with no record of it.

How we earn it
Your files stay yours.
Every move, provable.
We don't move your files
DataGuard reads your files where they already live and never keeps a second copy.
Private AI models
Sidian's own private models. Never OpenAI, never Anthropic. Never trained on your data.
Audit-ready by default
Every proposal, approval and send is recorded as it happens. The compliance file writes itself.
First redaction in five minutes. No IT project, no consultants.
