AI Data Protection for Small Legal Teams
A small legal team using ChatGPT to draft correspondence, summarise documents or research issues faces the same client confidentiality obligations as a top 50 firm. The risk is identical. The resources to manage it are not.
Ventrin is a Chrome extension that scans and sanitises employee prompts locally in the browser before they are sent to ChatGPT, Claude, Gemini or Copilot. When sensitive content is detected, Ventrin warns the employee, rewrites the prompt automatically, or blocks the send — depending on your team's policy. Sensitive data never leaves the device unintentionally. Admins see every risk event in a central dashboard.
The AI risk profile for small legal teams
Small legal teams often adopt AI tools faster than larger firms because there is no lengthy IT procurement process. A solicitor in a two-person firm can install ChatGPT and start using it tomorrow. The speed of adoption is the risk: there are no controls in place before the tool is in use.
Client names, matter references, privileged correspondence and personal data are being pasted into AI tools daily, across thousands of small legal practices, with no logging, no policy enforcement and no visibility for the practice manager or compliance officer.
The SRA expects firms of all sizes to manage their data protection obligations. The size of the team is not a defence.
Names, matter references and legal advice sent to third-party AI services without client consent or data processing agreements.
The SRA's guidance on technology and innovation requires firms to maintain appropriate controls over confidential information.
Client PII, witness details and employee data processed through AI tools without lawful basis or appropriate safeguards.
When a data exposure occurs, a firm without event logs cannot demonstrate what happened, when, or what was done about it.
Data breaches facilitated by AI tool misuse may have implications for professional indemnity insurance claims.
Practical AI protection built for small teams
Ventrin gives small legal teams the same protection larger firms implement through enterprise security platforms — without the enterprise complexity or cost. The extension installs in two minutes. Policies are configured from a simple admin dashboard. No IT department required.
Ventrin detects client identifiers, personal data and credentials before they reach ChatGPT, Claude or Gemini. It rewrites prompts to preserve the task while removing sensitive details. Every flagged event is logged, giving practice managers a clear audit trail.

Incident visibility
Your team is using AI tools without meaningful data protection controls. The risk of client data exposure is significant.
You have some awareness of AI data risk but enforcement is manual and incomplete. Technical controls would close the gap.
You have solid foundations. Adding a technical enforcement layer would give you complete coverage and an audit trail.
Your policies are well structured. Ventrin would add browser-level enforcement and event logging to complete your AI security posture.

Local-first detection
The scanning model runs in your browser, not on our servers. Sensitive content never leaves the device for analysis.
No data egress
Ventrin does not receive, store or process your team's prompt content. Only risk event metadata is logged.
Configurable policy controls
Warn, sanitise or block based on content type and team role. Full control over how the extension behaves.
Admin event logs
Every flagged event is recorded with risk type, action and timestamp. Provides the audit trail your compliance process needs.
Protect your team's AI use from the browser
Ventrin deploys as a Chrome extension. No proxy, no network change, no IT project. Most teams are protected on the same day.
Frequently asked questions
Yes. Ventrin is designed to work for teams of any size. A small practice without an IT department can deploy it from the admin dashboard in minutes. There is no infrastructure requirement and no minimum seat count.
Ventrin detects patterns associated with personal names, contact details, dates of birth and financial figures. It also detects matter references, case codes and common legal document patterns. Legal-specific policy templates are available in the admin dashboard.
You can install Ventrin for individual users rather than the whole firm. The admin dashboard shows events per user. A practice manager could deploy it for fee earners handling the most sensitive matters first and extend gradually.
Ventrin helps you implement a technical control for AI prompt data protection. SRA compliance depends on the overall framework of policies, training, supervision and technical controls your firm has in place. Ventrin is one element of that — it is not a complete compliance programme.
Yes. Ventrin covers all major browser-based AI tools including ChatGPT, Claude, Gemini and Microsoft Copilot. If your team uses multiple AI tools, the same policy applies across all of them from one extension.
The audit log records every flagged event with risk type, action taken, AI tool used and timestamp. It shows whether a prompt was warned, sanitised or blocked. This gives a practice manager a clear account of what the system detected and when, which is useful in an incident review or regulatory conversation.
