What are the Top Microsegmentation Solutions for 2026?

Network attacks now bypass old security walls with ease. CISOs face a choice: stick with failed perimeter defenses or adopt microsegmentation tools that actually stop lateral movement attacks where they happen.

Why Microsegmentation Matters for Your Bottom Line

Data breaches cost more each year. According to IBM's Cost of a Data Breach Report 2025, the global average cost of a data breach reached $4.88 million in 2024, up from $4.45 million in 2023. Healthcare takes the biggest hit with average breach costs at $9.77 million.

Lateral movement attacks drive most of these costs. Attackers slip past the network edge, then roam freely inside systems for months before anyone notices. Some hide in networks for over 280 days.

Companies save real cash with these tools. Manufacturing firms report $2-3 million in yearly savings just from avoiding downtime. Healthcare groups protect patient safety while cutting compliance costs. Financial firms isolate trading systems without slowing business. Utilities provide their services without disruption.
