What is Micro-Segmentation?

Micro-segmentation is a security technique that divides a network into small, isolated segments—each with its own security controls and access policies. Unlike traditional network segmentation that separates large zones (e.g., user VLAN vs. data center), micro-segmentation operates at a granular level—down to the workload, application, or even process level.

The goal is simple:

If a breach happens, contain it immediately and prevent it from spreading.

Why Traditional Segmentation Falls Short

• Static: VLANs or subnet-based controls are slow to adapt to dynamic cloud environments.
• Overly Broad: Once inside a segment, attackers often have excessive freedom.
• Network-Centric: Legacy segmentation is based on IP addresses and network zones, not on who, what, or why a system or user is accessing a resource.

Real-World Example

Imagine a hospital’s internal network. Without micro-segmentation:

• A hacker breaches one radiology workstation.
• That machine has access to patient records, billing systems, lab reports, and even IoT-connected MRI machines.
• The attacker moves laterally—silently—within minutes.

With micro-segmentation in place:

• The radiology workstation can only talk to a specific imaging database.
• It can’t reach the billing system, the EHR, or the lab systems.
• Even if compromised, the breach goes nowhere.

IronQlad's Advanced Micro-Segmentation Approach

At IronQlad, we go beyond basic segmentation. We implement dynamic, context-aware, identity-aware micro-segmentation using a combination of agent-based enforcement, Zero Trust policies, and real-time telemetry.
