Enterprise Network Hardening

Overview

Designed and deployed secure enterprise-grade network environments with VLAN segmentation and centralized authentication.

Stack Used

• Cisco
• pfSense
• VLANs
• Active Directory
• SIEM

Problem

Enterprises had flat networks, misconfigured AD, and lacked visibility into lateral movement.

Approach

Implemented pfSense firewalls, VLAN segmentation, and Active Directory integration with proper role-based access. Connected logs into SIEM for monitoring.

Results

Reduced lateral movement risk, enforced least-privilege access, and improved audit readiness.
