Understand AI. Recognise risks. Act safely online.
The focus: using AI safely and in line with the law. Plus IT security, NIS2, networks, smart home, video and access.
The most important topic: everyone uses AI, whether they notice it or not.
Basics, risks, security, rules in the EU, USA and Germany.

1 · The beginning
Most attacks start harmlessly: an email, a link, a device without updates.
2 · The protection
Identities, endpoints, network, applications, data and people. Each layer stops part of it.
3 · The response
Monitoring sees what slips through. An emergency plan sets out what happens next.
4 · The whole picture
AI, networks, video, access and smart home need a shared security concept.
Clear language instead of jargon. Every term is explained before it is used.
It is about principles and standards, not individual products.
Checklists, calculators and diagrams you can try out right away.
No cookies, no tracking, no external fonts. The calculators run locally in your browser.
Based on standards such as ISO 27001 and EN 62676 and the guidance of the German data protection authorities.
Guidance does not replace professional or legal advice. Where things get serious, I say so.
