Let’s be honest-cybersecurity isn’t something you can just set and forget. Threats pop up fast, and if you’re not thinking a few steps ahead, things can get messy quickly. That’s where threat modeling really shines. It’s not just a fancy buzzword-it’s a smart way to spot potential risks before they turn into full-blown headaches. Europe has tons of companies doing interesting stuff in this space. Some lean heavily on AI, some stick to hands-on consulting, and some mix the two. Here are a few that caught our eye.
