A 40-branch regional bank came to Nexsec after a near-miss intrusion exposed gaps in their aging perimeter defenses. Over four months, we rebuilt their network security architecture from the ground up.

The bank's branch network had grown organically over fifteen years, layering firewalls and VPN configurations from four different vendors. Visibility across branches was fragmented, and their security team had no unified view of traffic patterns or anomalies — leaving blind spots attackers could exploit for weeks before detection.

We consolidated all 40 branches onto a single, centrally managed security fabric with standardized next- gen firewalls and unified threat intelligence feeds. A dedicated SOC team was stood up within six weeks to provide continuous monitoring across the entire network.

Within the first quarter of full deployment, intrusion attempts dropped sharply and mean time to detect fell from days to minutes. The bank's compliance team also passed its next regulatory examination without a single security finding.
