AI stack for SMEs: assess privacy and operations

A suitable AI stack follows the specific process and its data. A provider name, EU headquarters or self-hosting alone does not establish compliant processing.

In short

A suitable AI stack follows the specific process and its data. A provider name, EU headquarters or self-hosting alone does not establish compliant processing.

From use case to a limited pilot

1

Task

Define one task: document required inputs, expected output and an accountable owner.

2

Data flows

Map systems and data flows; clarify allowed fields, agreements, regions, retention and deletion.

3

Test

Start with anonymized examples. Test access failures, unsuitable answers, outages and human takeover.

4

Acceptance

Accept results and record open issues. Assign ownership for operations, updates, cost control and shutdown.

Avoid false conclusions

  • No training use does not mean no storage or exclusively regional processing.
  • Automated actions need their own permissions; a good model answer is not approval.
  • A subscription price does not cover all hosting, usage, integration, review and team time.

Frequently asked questions

Is self-hosting automatically the right choice?

No. It offers control but requires operational expertise. Assess external connections, updates, permissions, backups and recovery just as with a cloud solution.

How should we select a provider?

Compare specific product and contract options on the same task. Privacy and IT owners assess actual data flows; technical selection is not blanket legal approval.
