Enterprise Security Operations Centre (SOC) Implementation

Business Challenge

A regional bank with 2,000 employees had no centralized security monitoring capability and was detecting incidents days to weeks after they occurred. A near-miss ransomware incident triggered the board to mandate a fully operational SOC within 6 months.

Solution & Approach

Phronex™ led the SOC design and implementation: Splunk SIEM deployment with 85 custom detection rules tuned to the bank's environment, CrowdStrike endpoint deployment across 2,000 devices, SOAR playbook development for the 20 most common incident types, and SOC analyst hiring and training.

Capabilities Delivered

• Splunk SIEM deployment and 85 custom detection rules
• CrowdStrike endpoint protection across 2,000 devices
• SOAR playbook development for top 20 incident types
• SOC analyst hiring, onboarding, and training program
• Mean time to detect and respond (MTTD/MTTR) baseline

Business Outcomes

MTTD reduced from weeks to under 4 hours, and MTTR improved to under 2 hours for tier-1 incidents. The SOC detected and contained 3 active threats in its first 90 days. The bank passed its next regulatory examination with commendation for security controls.
