Frozen river landscape used for Frozen River Security branding

River AI Appliances

Private AI for law offices.

River AI is a firm-controlled AI workspace for legal teams that need document review, matter-specific answers, drafting support, conflict intake, and auditability without sending sensitive client data to public AI tools.

River Sentry, our security suite, runs on the same appliance — so the box that brings AI into your practice also closes security gaps you are already carrying. Included for Founding Firm Pilot members.

Appliance-based

Runs on dedicated mini PC or workstation-class hardware sized for the office workflow.

Matter-aware

Organizes documents, questions, citations, drafts, notes, tasks, and evidence around matters.

Security-first

Admin control, signed updates, local guardrails, prompt screening, audit logs, and backup verification — with our River Sentry security suite on the same box.

A legal workspace, not just chat.

River AI is designed to feel like an associate attorney workspace: answer, supporting citations, relevant documents, suggested draft, risks, and confidence.

Matter workspaces for documents, evidence, drafts, notes, and tasks

Citation-backed answers over approved matter records

Reads scanned and photographed pages, not just typed documents

Conflict intake and review workflow

Attorney and paralegal dashboards

Audit logs, backup checks, rollback, and admin model controls

Private AI on office-controlled hardware

Firm-controlled AI model profiles

Signed local updates and signed model bundles

Screens documents for hidden instructions meant to trick the AI, and sets suspicious ones aside

The system cannot reach the internet on its own, by design

Known-good restore markers for operational recovery

We test that your backups actually restore — not just that a backup ran

Safe practice phishing emails to your staff, so you find out who clicks before a real attacker does

A check that every login has a second step turned on, and that former employees no longer have access

Watches what is connected to your office network and flags anything that should not be there

Stops outsiders from sending email that looks like it came from your firm

A plain-English report you can hand your malpractice carrier — and it never calls something safe when nothing is actually watching it

It closes security gaps, too.

Most small firms already know where they are exposed — backups nobody has ever tested, staff nobody has trained against fake emails, old logins nobody has closed. River Sentry runs on the same appliance, so bringing in AI and closing those gaps happen in one visit instead of becoming two separate projects. It is included for Founding Firm Pilot members and available as an upgrade after that.

Pilot program for law offices

Frozen River Security is shaping River AI with a small number of firms that handle sensitive documents and want practical AI without public-cloud exposure — and want their security gaps closed at the same time.

Step 1

We install the appliance and bring its security suite online — one visit, no changes to your systems

Step 2

You pick one or two real matters to run it on

Step 3

Your team works normally — attorneys ask, draft, and review; we check in weekly

Step 4

We customize your dashboard, apps, and workflows to fit how your practice actually works
