CattleGrid is a British technology company that provides a security system to protect organisations using AI services like Anthropic’s Claude, OpenAI, Google’s Gemini and more. Think of it as an invisible security checkpoint that reviews everything your team sends to an AI Provider before it ever leaves your control.

When employees use AI tools to assist with their work, they might accidentally include sensitive information—such as customer National Insurance numbers, credit card details, medical records, or confidential company secrets. CattleGrid detects this data and prevents it from being sent, keeping your organisation safe and compliant with data regulations.

Without CattleGrid:

  • An employee pastes customer data into an AI chat without thinking
  • Sensitive information leaves your network and goes to external servers
  • Your organisation may violate privacy laws (HIPAA, GDPR, PCI-DSS)
  • You have no record of what was sent or when
  • You only find out about the problem after damage is done

With CattleGrid:

  • Every AI request is automatically scanned before it is sent to the AI platform
  • Sensitive information is detected and blocked instantly
  • The employee sees a clear message explaining what was blocked and why
  • Administrators receive immediate alerts about policy violations
  • Complete records are kept for compliance audits

At its core, from first principles, Cattlegrid serves as a critical control layer for organisations seeking to align with ISO 42001and GDPR legislation by providing the necessary oversight and risk mitigation for enterprise AI adoption. By implementing a Zero Trust, Zero Retention model—characterised by memory-only processing and outbound-only inspection—the platform ensures that sensitive data is restricted from ever exiting the organisation without oversight and supportsthe data minimisation and storage limitation principles championed by the ICO and required for ethical AI governance
