Cybercriminals are moving faster than ever, exploiting implicit trust within networks to spread ransomware and execute supply chain attacks.

In response, microsegmentation is gaining momentum as a key cybersecurity strategy—one that could take center stage as RSAC 2025 gets underway next week at San Francisco’s Moscone Center.

At its core, microsegmentation isolates assets within a network, limiting the blast radius of an intrusion. The approach has long been recognized as a security best practice, yet widespread adoption has lagged due to complexity and operational challenges.

However, with automation and zero trust principles reshaping cybersecurity, organizations are now revisiting microsegmentation as a critical defense mechanism.

I had the chance to sit down with Albert Estevez, Field CTO at Zero Networks, to discuss the next evolution of microsegmentation, emphasizing the role of automation in making it scalable and frictionless. “Traditional microsegmentation has been hard to implement,” Estevez explained. “But by automating the process and enforcing zero trust policies at the IP level, we remove that complexity and make it practical for real-world networks.”

A strong argument can be made that with attacks increasing in speed and sophistication, segmentation is no longer optional—it’s an essential piece of modern zero trust security architectures. For a full drill down, please give the accompanying podcast a listen.

The question now is whether automation-first approaches, like those championed by Zero Networks, will finally make microsegmentation the standard rather than the exception. I’ll keep watch and keep reporting.
