Stop sensitive client information from leaving your firm.
DataGuard removes it from every document and email before it goes out, and records what changed.
From $39 per user per month. Setup takes 5 minutes. 30 days free.
How it works
Three steps. Nothing changes for your team.
Your team shares as usual
Inside Outlook, Gmail, OneDrive, SharePoint, Drive and Clio. There is no new app to open.
DataGuard reads it first
It reads the whole document and finds what should not go out: names, social security and account numbers, medical details, and anything privileged. Each one is checked against the rules your firm answers to.
The clean version goes out
Routine removals happen automatically. Anything uncertain goes to a reviewer. Every decision is recorded.
Your team. Each person sees only the matters their role allows.
AI tools. Client identifiers are stripped before anything reaches ChatGPT or Copilot.
The outside. Each recipient gets only the parts meant for them.
One policy. One audit log. Every move defensible.
A 500-page production, reviewed at 20 to 40 pages an hour, is 12 to 25 hours of paralegal time. At the national average paralegal billing rate of $134 an hour, that is $1,700 to $3,300 before a page is shared.
A person still approves every send. They just don't do the 500-page read.
Paralegal billing rate: NALA national survey, 2024. The pages-per-hour range is our own estimate, not a published figure.
Your data stays yours
Your files never move.
Read where they live
Microsoft 365, Google Workspace, Clio. No second copy is ever made.
Private models only
Sidian's own. Never OpenAI, never Anthropic, never trained on your content.
Analyzed, then discarded
Nothing is kept. Only the record of what was removed.
What brought you here?
Most firms arrive after a specific moment.
A near-miss just happened
Something went to the wrong party, or nearly did.

Why Purview fails law firmsFAQ
Because the cost of one accident has gone up and the odds haven't gone down. 55% of leaks are mistakes, not attacks, and you don't get to un-send a disclosure. Meanwhile malpractice carriers and corporate clients are beginning to ask for proof of controls, and your staff are already pasting case facts into AI tools. The firms that get ahead of this do it before the near-miss, not after.
Yes. DataGuard handles routine redactions automatically so nothing waits in a queue, but anything uncertain is routed to your reviewer for a one-click approve, edit, or override. Judgment stays with the lawyer. Both the engine's decisions and every human override are logged, so the record is complete either way.
Purview is built to block shares and flag violations after the fact. It doesn't redact, and it doesn't let the document through. DataGuard removes only what shouldn't leave and sends the rest. Your paralegals stay productive. Nothing gets blocked. The two tools serve different purposes.
Yes. That's the internal-access layer, live today. The same policy that decides what leaves the firm also decides what each person can open inside it. Staff see only the matters their role allows, conflict screens are enforced automatically, and every access is logged.
Your team is already using AI. DataGuard's AI privacy layer strips client identifiers from text before it reaches the model, so the assistant never sees the sensitive details. You keep the productivity without creating an unlogged disclosure.
It's analyzed in memory and immediately discarded. Nothing is stored as content, logged with its sensitive values, or used for training. Analysis runs only on Sidian's own private models, never OpenAI, never Anthropic, never any third-party AI. Attorney-client privilege stays fully intact.
Small firms are exactly who this was made for. You carry the same client data and the same duties as a large firm, with less margin to absorb a hit and no enterprise IT team. DataGuard gives you the data-governance standard used in highly regulated government systems, deployed in minutes, with no configuration project.
Under 5 minutes. It connects to the tools you already use. No IT team required, no configuration project, no training required. Your team is protected from day one.
From $39 per user, per month, first month free. A document is one file of any length, so a 10,000-page production counts as one. See plans
