What do I put in a DPA breach report?

The Dutch DPA form asks fairly specific things. Better prepared than ad-hoc.

Try this first

  1. 1Nature of the breach: technical (hack, malware), human (wrong mail), physical (lost laptop). Be factual, not 'we were attacked by state hackers'.
  2. 2Number of people affected: estimate an order of magnitude. 'Unknown, estimated between 50 and 500'. Do not dramatize, do not downplay.
  3. 3Type of data: list the categories. 'Name, email, phone'. Sensitive categories (health, financial, citizen number) call out separately.
  4. 4Possible consequences for individuals: identity theft, financial harm, reputational damage. Be realistic.
  5. 5Measures taken or planned: technical (password rotation, MFA enforcement), procedural (training), communication (mail to those affected).

When to bring us in

For a heavier notification (medical data, children, large numbers): have a GDPR expert review. We have a regular partner, one evening of work saves a lot of hassle later.
