When I first got into this sector I was a total newbie with tech, security and all those IoT devices. I used to think IT security was just about keeping the bad guys out – firewalls, passwords, less cyber drama. For many, that’s still the case. Security often feels like an obligation, something pushed by compliance checklists, directives and policies. But the more I learned, the more it felt like investing in security isn’t just investing in safety – it’s investing in comfort, in peace of mind.

At some point I started thinking, there’s gotta be more to all this than just cutting risks and staying comfy – so why does it actually matter so much to us to feel protected though?

Many people say, “because it’s the right thing,” or “because something bad could happen.” But this whole security topic goes far deeper than regulations. It’s rooted in one of our oldest biological instincts.

Our nervous system evolved to detect threat long before we invented firewalls. The amygdala (=our emotional fear center) reacts within milliseconds to anything that feels unsafe, kicking off a chain reaction of hormones – adrenaline, cortisol, dopamine – preparing the body for fight or flight. The same mechanism that once helped us survive predators in the stone age now also reacts when we see a phishing mail, a data leak, or Sora-generated deepfakes.

Don’t get me wrong, I’m not saying physical danger and digital danger are on the same level, just that our brains simply can´t tell the difference. A predator or a phishing mail both activate the same neural alarm. Over time we became hypersensitive, not because we’re weaker, but because our ancient survival system keeps getting triggered by modern threats. In other words, our environment evolved faster than our brains, so the same system that once saved our lives now keeps us in a small state of alert almost all the time.

Humans are funny that way; we crave safety, yet we’re addicted to risk. Both impulses come from the same biology. Genes like MAO-A, also called the warrior gene, regulate how much dopamine and adrenaline flow through our system. That tiny bit of DNA can push someone toward thrill-seeking or toward control – chaos or calm. One person loves bungee jumping and big waves, another prefers books and quiet rooms. It is soo wild to me how something so incredibly tiny can shape an entire personality??

Every moment of uncertainty kinda lights up the same parts in our brain that go off when we fall in love or win something out of the blue. That whole “won the lottery with your partner” saying is not just a metaphor, they literally trigger the same neural fireworks. Sounds like a fat double jackpot to me;) but once that rush fades, the body starts craving calm again. Serotonin, dopamine, cortisol – the endless loop of thrill and peace.

In today’s world, the context just changed, not the instinct. Those before us secured caves and borders; we secure networks and data centers. The predators changed, but the biology didn’t. Our fight-or-flight just runs on access control now.

Security isn’t just a product or a law like it´s being displayed almost everywhere. If I go full philosopher on this, this whole technological evolution is simply a mirror of our biological one, our fears, our craving for control in a world that moves faster than we can adapt. Funny, isn’t it? The same neural chaos that drives us toward danger is what makes us build walls to feel safe again. But unlike our ancestors, we now battle dangers of our own design: algorithms, breaches, autonomous systems. And yet, the neurochemical relief we feel when “everything’s secure again” hasn’t changed. Serotonin still floods the system, no matter if it´s stone age or 2025.

And honestly, that’s the biggest irony for me: we ourselves have become the source of the very threats we fear.. The systems we create to make life easier keep creating new vulnerabilities. Every digital leap comes with an emotional kickback, forcing our brains into an endless loop of innovation and defense. (don’t get me wrong, I absolutely LOVE the human drive to invention, this is not just a tech thing, it´s how we run as a species)

Maybe that’s the real paradox – the safer we try to make our world, the more we remind ourselves why safety matters. Security isn’t just protection, it´s biology and most of all, the proof of humanity.

It makes me wonder if safety was ever meant to be absolute, or if we’re just learning new ways to chase the same feeling.
