Once data leaves your system, your ability to control it rapidly diminishes. However there are steps you can take to mitigate risks:
- Only giving clients the data they require
- For example, with a centralized service application this would involve analyzing what each client needs, and applying logic so that they only receive that information.
- Actively engaging with client teams, asking them about security, guiding them. Even though the data has left your system, it is still your data and you need to ensure others are being careful with it.
