# Tell your customers when you are their processor

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Required
- Chapter: [Breaches and reporting](https://agentwranglers.se/playbook/compliance/breaches-and-reporting)
- Rule: When you process data for business customers, tell each affected customer about a breach without undue delay and within the hours your agreement promises.
- How: Article 33(2) places this duty on processors. Your customers then have their own 72 hours, so promise 24 or 48 hours, not 72. Store a security contact for every customer account. Send the first notice with what you know, and update it as facts arrive.
- Check: Every customer account has a security contact. In a yearly drill, a test notice reaches every contact within the promised hours, measured from the drill's awareness time.
