Last week, I found myself sitting in a bustling café in the heart of Berlin, listening in on the animated discussions of a group of local entrepreneurs. As a passionate tech journalist, I couldn't help but engage in their conversation when they started discussing the importance of cybersecurity for small businesses.

This moment highlighted a crucial need for strong protective measures. It was clear: a firewall is no longer an optional luxury—it’s essential for survival in today’s digital landscape.
