A system that no one fully understands anymore doesn't protect. It just keeps you busy.

At first glance, this sounds like a purely technical statement. It isn't. It applies to every company that operates IT infrastructure – regardless of industry and size.

More Does Not Equal More Secure

In IT infrastructure, a stubborn equation has firmly established itself: more tools mean more security. More layers mean more protection. More complexity means someone has thought about it thoroughly.

This equation is false.

Every additional component in a system is, first and foremost, one thing: another point of failure. Another dependency that must be maintained. Another configuration that must be understood. Another attack vector.

This compounds – quietly, over years, through many small decisions that were each entirely reasonable on their own. The result is systems that no single person fully oversees anymore. The moment something goes wrong, exactly this understanding is the only thing that counts.

When Well-Intentioned Rules Achieve the Opposite

A concrete example that almost every company is familiar with: the mandatory regular password change. A new password every 90 days, ideally with uppercase letters, special characters, and numbers – the more complex, the more secure. This was the gold standard recommendation for decades.

The result in practice: Summer2024!, Autumn2024!, Winter2025!. Passwords that technically meet every complexity requirement, yet remain trivial to guess. The rule did not create security. It merely channeled human creativity in the wrong direction.

The German Federal Office for Information Security (BSI) has now officially incorporated this realization into its recommendations: Experience shows that regular password changes lead to increasingly weaker passwords being used. [1] The US National Institute of Standards and Technology (NIST) has come to the exact same conclusion in its current SP 800-63B guidelines, explicitly recommending the abandonment of forced password changes. [2]

A security rule that forces insecure behavior is not a security rule. It is complexity masquerading as security.

The Tool That Screams the Loudest

There is a simple identifier for overly complex systems: they constantly make themselves heard. Warnings, status messages, alerts – a continuous stream suggesting that intense work is being done in the background.

What this noise actually creates is alert fatigue. If you receive twenty notifications a day, nineteen of which are completely irrelevant, you will eventually stop taking the twentieth seriously. This is not human failure. This is the highly predictable reaction to a poorly calibrated system.

A system that quietly does its job and only speaks up when it is truly relevant creates the exact opposite: absolute attention right where it is needed.

What Actually Works in Practice

Systems that prove to be stable and secure share one fundamental trait: you can explain them. Completely, without having to become vague.

This requires that their components are known, their behavior is documented, and their configuration is out in the open. Not the currently most-hyped tool that no one will maintain in two years. Not the all-in-one platform that hides twelve distinct functions behind a single user interface. But rather tools that have been in use for years, whose behavior is predictable – and that solve the exact problem they were built to solve. Nothing more.

This is not conservatism. It is a deliberate engineering decision with concrete consequences: significantly shorter reaction times in the event of an error, lower operating costs, and a team that actually knows what they are operating.

The Real Question

Before introducing a new component, there is exactly one question that needs to be asked: Does this solve a problem that hasn't already been solved?

If the answer is "maybe," "someday," or "the vendor recommends it," the direction is clear.
