  • Your name and contact details;
  • The date and time of the breach (or an estimate);
  • The date and time you detected it;
  • Basic information about the type of breach;
  • Basic information about the personal data concerned.

To better inform the affected customers you must write a message where you:

  • Think carefully about voice and tone, talk clearly and be frank without alarming users.
  • Tell your customers as much as you can about the data breach incident, advise and tell them how they must proceed. Be transparent.
  • Consider your audience. Different audiences may react differently, take that into consideration.
  • Make it clear. Write it clearly and understandable to everyone.

If you enforce your data protection measures, you are contributing to decrease the possible damage caused by a data breach.

Every system is faulty. What’s important is that companies to do the most they can to protect costumer’s data and to prevent the worst.
