Microsegmentation: the unsung hero of cybersecurity (and why it should be your top priority)

Let’s talk about the most overlooked tool in cybersecurity: microsegmentation. It’s not a buzzword. It’s not a luxury. It’s the backbone of resilience — and it’s time we moved it from the margins to the center of our strategy.

Here’s the simplest way I explain it: Microsegmentation isn’t about blocking access. It’s about reducing the blast radius. If one laptop gets compromised, microsegmentation ensures the attacker can’t move laterally to critical systems. It’s the difference between a contained spark and a wildfire.
