As answered by people managing CodeSandbox and ChatShield.
ChatShield's answer:
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's answer:
ChatShield is built specifically for UK law and accounting firms, not for enterprise IT teams. Three things make it different from traditional DLP:
ChatShield's answer:
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's answer:
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.
