Client Overview

A multinational bank used SOC operations to continuously monitor threats, protect transactions, reduce incidents, and maintain regulatory compliance.

Industry

Multinational Banking Sector

Duration:

[36 Months]

Services Provided:

24×7 SOC monitoring and cybersecurity operations services

The Challenge

The bank faced phishing, ransomware, insider threats, and persistent attacks targeting customer data and transactions. Manual log analysis, delayed escalation, skill shortages, compliance mandates, and 24×7 monitoring needs increased MTTD, MTTR, and overall cybersecurity risk.

The Solution

  • Alchemy established a 24×7 managed SOC with SIEM-driven monitoring across endpoints, firewalls, databases, applications, and networks.
  • Threat feeds, AI/ML analytics, and UEBA improved anomaly and insider threat detection.
  • SOAR automated log correlation, alert enrichment, and ticketing.
  • ITIL and NIST-aligned playbooks enabled faster containment, eradication, and recovery.
  • L1-L3 analysts, supported by a Cybersecurity Service Delivery Manager, ensured seamless escalation, while RBI, PCI-DSS, and ISO reports maintained audit readiness.
