ChatShield is AI governance for UK law and accounting firms. A browser extension and admin dashboard that stops staff accidentally sharing sensitive client data with ChatGPT, Claude, and other AI chat tools. What it does ChatShield sits in the browser and intercepts every message before it reaches an AI tool. Each message is scanned locally against your firm's DLP rules. When sensitive content is detected, the message is blocked, flagged, or sent with an audit entry. Message content never leaves the browser. Only metadata (which rule triggered, which AI tool, and when) is sent to the dashboard. Who it is for Built for managing partners, IT leads, and compliance officers at UK law and accounting firms with 3 to 50 staff. Designed for the realities of professional services: client confidentiality, regulatory scrutiny from the SRA and accounting bodies, PI insurance, and lean operations without dedicated security teams. What is included
Browser extension for Chrome and Edge Pre-built rule library covering UK PII, payment data, and client identifiers Custom rules in plain English (client names, matter or job codes, partner names, internal codenames) Admin dashboard with activity reporting, top triggered rules, and staff flagging Block, warn, and override severity levels with full audit trails Five-minute setup with no IT dependency 14-day free trial
Why firms choose ChatShield over enterprise DLP Enterprise data loss prevention products are priced and configured for FTSE 100 IT departments. ChatShield is priced for small firms (ยฃ8 per seat per month for founder customers, three-seat minimum) and configured by partners themselves in minutes. The result is a working control rather than a shelf-bound policy document. Compliance and privacy ChatShield is operated by Lura Labs Ltd (Company No. 17180996, registered in England and Wales). Message content is never transmitted to ChatShield servers. Activity metadata is processed under UK GDPR.
Real-time blocking in the browser
Messages are scanned locally and blocked before they reach ChatGPT, Claude, or other AI tools. Message content never leaves the browser.
Pre-built UK rule library
Covers UK PII (NI numbers, postcodes, phone numbers), payment data, and client identifiers out of the box. No regex or setup required.
Custom rules in plain English
Add the words and patterns specific to your firm: client names, matter or job codes, partner names, internal codenames. Type them as plain text.
Partner-facing dashboard
See which staff are using AI, which rules trigger most often, and where your firm's data risk sits. Full audit trail for compliance and PI insurance.
Block, warn, or override severity
Configure each rule to block hard, warn softly, or allow with a logged override. Staff get clear signals; partners get the evidence trail.
Managing partners, IT leads, and compliance officers at UK law and accounting firms with 3 to 50 staff.
These are firms that handle confidential client data daily, operate under regulatory scrutiny (SRA, ICAEW, ACCA, AAT), carry professional indemnity insurance, and do not have a dedicated internal security team. They have heard the AI conversation, written or downloaded an AI policy, and now want a way to actually enforce it.
Adjacent buyers include other professional services practices (consultancies, financial advisers, surveyors) that face similar client-confidentiality and regulatory pressures.
ChatShield is built specifically for UK law and accounting firms, not for enterprise IT teams. Three things make it different from traditional DLP:
Most firms have a written AI policy but no way to enforce it. They cannot answer the simple question: what did our team paste into ChatGPT this week? ChatShield closes that gap with a working control, not just a document. Choose ChatShield over enterprise DLP if you run a firm with 3 to 50 staff and you want to:
If you have a dedicated security team and a six-figure DLP budget, an enterprise product may suit you better. If you are a managing partner who wants a real answer to the AI question this quarter, ChatShield is for you.
ChatShield came out of conversations with UK law and accounting firms over the past year. A pattern kept showing up: every firm had a written AI policy, and almost no firm could tell us what their team was actually sending to ChatGPT or Claude.
The available tools were either enterprise DLP products priced and configured for FTSE 100 budgets, or generic security suites that did not understand professional services data. Neither fit the firms we were talking to.
So we built ChatShield. A browser extension that intercepts messages before they reach an AI tool, scans them locally against the firm's data loss prevention rules, and gives partners a dashboard of what is actually being sent.
