Network Security
The network is where lateral movement lives or dies. We design visibility, segmentation, and control so a single compromised host does not become a free tour of the estate.
Architecture
Trust zones, DMZs, cloud fabric design.
Visibility
Flows, DNS, east-west insight.
Controls
Firewall policy, NAC, segmentation.
Detection
Anomaly and C2 pattern awareness.
Modern network security pairs classic perimeter discipline with software-defined controls and Zero Trust networking — so the dam is not a single wall, but a system of locks and channels.
Network defense in depth
Network security for modern estates mixes classic perimeter skill with cloud and identity-aware controls.
North-south
Ingress/egress policy, DNS security, and egress monitoring for C2 and exfil.
East-west
Micro-segmentation and service identity so compromise does not freely roam.
Management plane
Hardened admin paths, jump hosts, and MFA on infrastructure access.
Continuous check
Config drift detection and periodic architecture review as the estate changes.
