Your security is Swiss cheese.
And that is a good thing.
There is no slice of cheese without holes — and no security measure without a weak spot. Anyone promising 100% security is selling a feeling. Anyone who stacks enough slices is building a wall.
The yellow wall

What you will learn
- Why the cheese-slice principle (the Swiss cheese model, after James Reason) is the most honest security model there is
- The concrete holes in the classics: firewall, VPN, MFA, endpoint protection — each one named rather than glossed over
- Why the number of layers is not what counts, but their independence — otherwise one stolen login opens all of them at once
- The structural mistake perimeter security shares with deepfakes: appearance instead of identity
- What NIS-2 has demanded in concrete terms since 6 December 2025 — and why §30 BSIG effectively requires defence in depth

Every slice has holes.
That is not an admission, it is the starting point. Once you know where the holes are, you can offset them.
