5 Questions to Ask Before Buying a Segmentation Solution

Learn the five critical questions to ask before buying a segmentation solution and avoid hidden risk with a Zero Trust architecture built to stop lateral movement.

Segmentation is supposed to limit risk, but the wrong design can quietly create more of it.

Most buyers focus on features, pricing, or how fast a tool deploys. That’s how organizations end up with segmentation that looks good on paper but falls apart under pressure.

This ebook cuts through the noise with the five questions that actually matter when evaluating segmentation solutions. Understand how architecture, visibility, and Zero Trust alignment determine whether segmentation contains a breach or helps it spread.

In this ebook, you’ll learn how to:

  • Spot architectural red flags that concentrate control and increase blast radius
  • Understand what real segmentation visibility looks like and why context matters
  • Tell the difference between true simplicity and shortcuts that create long-term risk
  • Evaluate whether a solution truly aligns with Zero Trust principles in practice
