ChatShield

Stop your team sharing sensitive client data with Copilot, ChatGPT and Claude. Set up in 5 minutes.

ChatShield helps professional services firms govern how their teams use AI tools like Copilot, ChatGPT and Claude. Staff use AI every day. Most firms have no visibility into what is being sent. ChatShield sits in the browser and checks every message before it reaches any AI tool - blocking content that matches your firm's rules and showing staff exactly why it was stopped. What ChatShield protects against out of the box: — Email addresses and phone numbers — National Insurance numbers and UK postcodes — Payment card numbers, sort codes, and IBANs — API keys and database connection strings — UK VAT numbers and Companies House registration numbers Set up in minutes, not days: Your admin defines the rules. Staff receive an invite link by email, install the extension, and it connects automatically. No IT department needed, no complex configuration, no tokens to paste. See what your team is sending: Your admin dashboard shows total messages scanned, everything that was blocked, which rules triggered most, and which staff members may need additional guidance. Real evidence that risk is being managed - not just a policy document. Your data never touches our servers: Rule evaluation happens entirely inside the extension. Message content is never sent to ChatShield. This is a core privacy commitment, not a marketing claim. Built for legal, accountancy, recruitment, and other compliance-aware SMEs: ChatShield is not positioned as an airtight security perimeter — it is a governance and training tool. It stops accidental exposure, creates an audit trail, and builds good AI habits across your team. Works on Chrome and Edge. Covers Copilot, ChatGPT and Claude with more platforms coming. 14-day free trial at chatshield.ai
