Network Segmentation & Microsegmentation

Flat networks are the reason ransomware spreads from a single compromised laptop to encrypting an entire organization in hours. Effective segmentation is the difference between an incident and a catastrophe. Mjolnir designs and implements segmentation strategies that contain blast radius without breaking the way your business actually works.

Segmentation Strategy & Design

Most organizations approach segmentation as a firewall rule problem. We approach it as an architecture problem.

• Asset inventory and trust boundary identification
• Macro-segmentation strategy across data centres, cloud, and remote locations
• Microsegmentation design for east-west traffic within trust zones
• OT/IT boundary design for environments with industrial control systems
• PCI DSS and HIPAA scope reduction through targeted segmentation

Implementation & Migration

Segmentation only works if it actually gets deployed without breaking the business.

• Discovery and dependency mapping before any policy enforcement
• Phased rollout with monitor-then-enforce pipelines
• Illumio, Guardicore, Cisco Secure Workload, NSX, and cloud-native segmentation
• Application owner engagement and exception management
• Operational handover with policy management runbooks

Validation & Continuous Verification

Segmentation policies decay. We help you keep them effective.

• Policy drift detection and reconciliation
• Penetration testing of segmentation boundaries (lateral movement testing)
• New asset onboarding and policy lifecycle management
• Annual segmentation effectiveness reviews and tuning
