A Security Operations Center built for a leading private bank. The institution was processing an average of 4.2 million financial transactions daily under PCI-DSS and international financial regulatory requirements. However, its existing security infrastructure consisted of siloed point solutions; threat correlation was manual, and the mean time to detect (MTTD) averaged 72 hours.
We designed a three-tier SOC architecture comprising a centralized log aggregation layer on Elastic SIEM, a network monitoring module powered by Suricata IDS/IPS, and proprietary statistical anomaly models. Through SOAR integration, we defined automated response playbooks for 14 distinct incident types. The entire infrastructure was deployed on-premise within the bank's own data center.
