2025-07-06: Freedom first – and security follows naturally: Why IT must embrace openness

If there’s one thing I’ve learned in my many years working in IT, it’s this: freedom is the foundation of everything we consider secure and trustworthy. Especially in technology, I constantly see how freedom is often sacrificed for the illusion of greater security. But in reality, it’s quite the opposite: freedom is what truly enables real security in the first place.

You might be wondering what exactly I mean by that. Allow me to explain.

🔍 Freedom means control — and that means security

When I speak of freedom in the context of IT, I primarily mean the freedom to decide for yourself what happens with your data. The freedom to use software as you see fit, fully aware of what it does behind the scenes.
The opposite of this is closed systems where you simply have to trust that a vendor is doing things right — without ever being able to verify it.

Open Source software gives you this freedom back. Anyone can look at the source code and audit it. There are no hidden functions, no secret backdoors.
🔒 Encryption ensures that your data remains yours alone, accessible only to those you explicitly authorize — and to no one else.

So it becomes clear: freedom isn’t a risk here; it’s your strongest safeguard. As a user or business, you retain control. And from that, true security follows automatically.

🕊️ Edward Snowden, Julian Assange — and what that means for your IT

Edward Snowden revealed to the world just how deeply governments can invade our privacy when no one is watching. He warned us that surveillance and secrecy come at the expense of our freedom — and ultimately undermine our security as well.

Julian Assange, through WikiLeaks, exposed abuses of power that would have remained hidden otherwise. He made sure misconduct came to light. Both, in their own way, demonstrated that without transparency, there can be no freedom. And without freedom, there is no genuine security.

This is not merely a political debate. It directly affects your IT systems every single day. Because the more you rely on closed platforms, the less you know about what’s happening behind the scenes. And the more you depend on mere promises, instead of verifiable facts.

💼 How I, as an IT service provider, turn freedom into a security strategy

This is why I’ve made it a point in my work as an IT service provider to rely consistently on freedom software. That means:

  • 🌐 I recommend open-source solutions, developed and reviewed by diverse communities.
  • 🔒 I implement strong encryption so your data truly belongs to you.
  • ✅ I rely on open standards that won’t lock you into a single vendor’s ecosystem.

This not only protects your privacy but also makes your systems more robust overall. Because flaws are detected and fixed more quickly. Because if needed, you can always switch providers or adapt the software without having to overhaul your entire business infrastructure.

In this way, freedom becomes the very foundation of your security — not its opponent.

✉️ My invitation to you

I invite you to take this thought with you:
Freedom first — and security will follow naturally.

Let’s work together to ensure your IT is set up so that you can act confidently and securely, not just today, but well into the future. For you as an individual, for your company, and for a digital world where we all get to keep our freedom.

If you’d like, I’d be glad to show you exactly what this could look like for your specific situation. Please feel free to reach out to me.

2025-05-26: Open Source Software: Digital Freedom

Open source software is no longer a niche topic – it forms the backbone of our digital world. Many people are unaware of this, but the majority of computers around the globe already rely on open source technologies. In particular, the internet runs heavily on open source: most web servers operate using the Linux operating system, and countless services and applications – from web browsers to content management systems – are built on open source foundations.

🔍 What Does Open Source Mean?

Open source means that a software’s source code is publicly accessible, modifiable, and free to use. This transparency not only fosters trust but also enables global, collaborative development. Control does not rest with a single company or state – it lies with the community. This prevents users from being locked into expensive subscription models or becoming dependent on individual vendors – a scenario that’s increasingly common with proprietary software.

This issue is strikingly portrayed in the latest season of the series Black Mirror (Season 7, Episode 1): A woman receives a medical chip implant after having a brain tumor removed. The twist? The chip is permanently connected to the provider’s cloud – all data and functionality are processed externally, with nothing stored locally. Without an active subscription, the chip stops working. The software operates on a tiered licensing model with steadily rising costs. Eventually, the woman’s family can no longer afford the increasingly expensive subscription levels – leading to catastrophic consequences.

This dystopian scenario highlights how dangerous it can be when essential technologies are fully controlled by a central provider. It creates a total dependency – both technically and financially. Open source offers a radical alternative: transparent, decentralized, user-controlled, and free.

🧩 Freedom Through Technology

Open source is an expression of digital self-determination. Those who use free software decide for themselves what runs on their devices, what data is shared, and which functions are enabled. This independence is more than just a technical detail – it’s a political statement in an age of digital surveillance, data exploitation, and monopolization.

A particularly powerful example of open source as a vehicle for independence is Bitcoin. Here too, the entire source code is publicly available, every transaction is verifiable, and the system itself is not centrally controlled. The idea of freedom, transparency, and decentralization is central – and would not be possible without open source.

🔐 Security Through Encryption

In an age of widespread digital surveillance, protecting private communication is essential. Open source plays a crucial role here: only with publicly accessible source code can users verify whether a tool is truly secure. Encryption tools such as PGP for email or decentralized messengers like Matrix (with clients like Element) are vital for maintaining privacy and shielding digital conversations from prying eyes.

🤝 A Call to Support Open Source

The benefits of open source are overwhelming: transparency, security, independence, and innovation. But none of this happens automatically. The development and maintenance of free software is often done voluntarily or underfunded. That’s why it’s essential that we not only use open source but actively support it – by contributing to development, reporting bugs, or donating to projects that benefit us all.

Here is a short list of the most famous open source programs:

1. LibreOffice
Free and powerful office suite – alternative to Microsoft Office

2. GIMP
Free image editor – comparable to Adobe Photoshop

3. Mozilla Firefox

4. Thunderbird

5. VLC Media Player

🔗 https://www.videolan.org/vlc/

6. Audacity

7. Krita

9. KeePassXC
Secure and cross-platform password manager
🔗 https://keepassxc.org/

10. Shotcut
Free, open-source video editor with wide format support
🔗 https://shotcut.org/

✅ Conclusion

In the digital age, open source is not a luxury – it’s a necessity. There is hardly a more powerful tool for freedom, self-determination, and privacy protection. Those who want a free society must also support free software. It’s up to all of us to promote open source – for a digital world that liberates, not controls.
