Nothing sensitive leaves your org.
We prove it.
DataGuard removes the sensitive parts from every share, to your team, to AI, and to the outside, and records what it left out and why. Clean work flows through. Only the sensitive parts stay behind.
A breach becomes a footnote, not a crisis.
Hey Ben, found this record from our client. Can you review the details?
Under CPRA §1798.140(v), Email Address is classified as Contact Information and must be removed.
Everyone guarded the front door.
The leak walks out the back.
For years, security spend kept hackers out: firewalls, encryption, EDR. That problem is largely handled. The exposure almost no one built for is on the inside: your own people accessing data they shouldn't, and sensitive data leaving in everyday sharing and reporting.
The front door
Hackers breaking in
Perimeter, endpoint, encryption. Real and necessary, and largely solved by your storage provider.
The back door
Your own people
Over-permissioned to everything, and over-sharing in reports and disclosures. Nobody is watching this door.
Most leaks aren't break-ins. They're an authorized person seeing, or sending, something they shouldn't, and no record of who did what. And you're usually the last to know. Your client, your regulator, or the press tells you first.
It's not if.
It's when, and what it costs.
You hold the same sensitive data, and the same duties, as a Fortune 500, with none of the budget or team to match. Enterprise liability. Consumer-grade controls.
The insider look
A staffer opens a record they have no business reason to see.
The hidden-data report
A report or export ships with data still underneath: hidden columns, metadata, redactions over live text.
The wrong recipient
Autocomplete sends a file to an outsider, or the wrong attachment goes out the door.
An enterprise absorbs a $10M hit. You can't. And with no record of what happened, you can't even mount a defense.

One policy.
Enforced everywhere.
Define the policy once. DataGuard applies it to every access and every share. Clean work flows through, sensitive data doesn't. It records the basis for every decision.
Reads everything before it leaves. One screen, every channel.
Your team
Per-role views inside the same document. Each team sees only what its job needs. Nobody sees everything.
AI tools
Your team is already pasting data into ChatGPT and Copilot. The sensitive parts are stripped first, so the model never sees it.
The outside
One source goes out scoped to each recipient, under the rule that governs them. The wrong thing can't leave.

Wherever your data moves,
we redact it.
Outbound email
Scans every email and attachment before it sends. Redacts sensitive data automatically and catches the wrong recipient. Redact, don't block.
Bulk external sharing
Days of manual document review become one secure send. Bulk-redact hundreds of files; every finding cites the rule behind it.
AI prompts
Your team is already pasting data into ChatGPT and Copilot. DataGuard strips sensitive details first, so the model never sees it.
Already have a security team? Keep it. We govern the people you let in, on the tools you already use.
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 decision recorded automatically. The compliance file writes itself.
Live in under five minutes. No IT project, no consultants.
A document is one file, any length. A 10,000-page production counts as one, so a monthly limit goes further than it looks.
