Enterprise SOC & Threat Detection Implementation

Industry: Financial Services
Project Type: Security Operations Centre (SOC) Implementation
Environment: Cloud, On-Premises & Hybrid Infrastructure
Security Focus: SIEM, Threat Detection, Security Monitoring & Incident Response Automation

Project Overview

Designed and implemented a centralised Security Operations Centre (SOC) solution for a financial services organisation operating across cloud, on-premises and hybrid IT environments.

The project focused on strengthening the organisation’s cybersecurity capabilities through centralised security monitoring, advanced threat detection, automated incident response workflows and improved security visibility.

By implementing Microsoft Sentinel and integrating multiple security data sources, the solution enabled more effective threat identification, streamlined security investigations and improved the organisation’s ability to detect and respond to potential cyber threats.

The implementation also supported security governance and compliance objectives aligned with PCI DSS and ISO/IEC 27001.

Business Challenges

The organisation faced several cybersecurity challenges affecting security visibility, threat detection and incident response capabilities.

Key challenges included:

  • Fragmented Security Monitoring: Limited centralised visibility across cloud services, internal networks, servers and security infrastructure.

  • Delayed Threat Detection: Difficulty identifying suspicious activities and potential cyberattacks across distributed systems.

  • Manual Security Investigations: Time-consuming log collection, alert analysis and incident investigation processes.

  • Limited Threat Intelligence: Insufficient integration of external threat intelligence to support proactive threat detection.

  • Operational Inefficiencies: Security teams relied on multiple tools and manual processes to investigate potential threats.

  • Compliance Requirements: The need to strengthen security monitoring, audit logging and incident response capabilities to support PCI DSS and ISO/IEC 27001 requirements.


Security Solutions Implemented

1. Centralised SIEM Implementation

Implemented Microsoft Sentinel as a centralised Security Information and Event Management (SIEM) platform to consolidate security monitoring across the organisation.

2. Cloud & On-Premises Log Integration

Integrated security logs and telemetry from cloud services, identity platforms, servers, network infrastructure and other relevant security systems to improve visibility across the environment.

3. Advanced Threat Detection

Developed and configured security analytics rules to identify suspicious authentication activity, privilege escalation attempts, potentially malicious behaviour and other security threats.

4. Security Monitoring Dashboards

Designed SOC dashboards and security workbooks to provide security analysts with improved visibility into alerts, incidents, security trends and monitored infrastructure.

5. Automated Incident Response

Implemented security automation workflows to streamline alert handling, incident enrichment, notifications and selected response activities.

6. Threat Intelligence Integration

Integrated external threat intelligence sources to support the identification, investigation and prioritisation of potential security threats.

7. Alert Correlation & Investigation

Improved security event correlation and investigation workflows to help analysts identify related suspicious activities and prioritise security incidents.

8. SOC Operational Enablement

Provided operational documentation, investigation guidance and analyst training to support effective use of the implemented security monitoring solution.
