Business Need

The client is a leading name in the manufacturing sector, specializing in energy and environmental engineering solutions, with an annual revenue of ₹10,389 crore or approximately $1.25 billion USD for FY 2024–25. Operating in a hybrid cloud environment, the company faced increasing cybersecurity risks threatening its operational resilience and industry reputation.

To mitigate these risks proactively, the client aimed to strengthen its cybersecurity framework through continuous 24×7 SOC monitoring, robust vulnerability management, and enhanced application security practices. Before engagement, the company lacked mature incident response capabilities and was vulnerable due to limited investigation and oversight of security alerts.

Business Challenges

Multiple inefficiencies and systemic gaps affected the client’s cybersecurity operations, including:

Limited Asset Coverage
Not all assets were integrated with the legacy SIEM (ArcSight), making the enterprise prone to cyberattacks.

Inadequate Monitoring
Existing dark web surveillance was limited to 8×5 support, risking a delayed response to critical data leaks.

Operational Gaps
Internal audits flagged key weaknesses in monitoring and asset coverage.

Urgency of Migration
A 60-day window was mandated to complete migration from the existing SIEM before offboarding.

Manual Processes and Alert Fatigue
Security alerts were not being investigated in detail, and key alerts were missed due to high volumes and a lack of actionable context.

Legacy solutions—including Arcsight SIEM and Cyble Dark Web monitoring—lacked advanced analytics, detailed investigation workflows, and full-time operational coverage, necessitating a rapid and robust transformation.

Solution Implementation

NuSummit Cybersecurity implemented a full-stack cybersecurity operations solution anchored by QRadar SIEM to address these urgent needs. The transformation was structured across four critical phases: Kickoff and Information Gathering, SIEM Implementation and Log Source Integration, Use Case Validation and SOAR Enablement, and Operational Transition.

This phased approach ensured rapid, scalable deployment aligned with the client’s security and compliance objectives.

Key Capabilities Delivered

As part of the engagement, NuSummit Cybersecurity delivered the following key capabilities to enhance the client’s detection, visibility, and response posture:

Advanced Detection Coverage
Over 400 custom use cases were developed, achieving 89% coverage of the MITRE ATT&CK framework tailored to the client’s environment.

Asset-Wide Integration
All servers listed in the asset inventory were onboarded to SIEM, ensuring 100% monitoring coverage.

Custom Integration Engineering
Seamlessly ingesting logs from ERP systems and proprietary applications via custom parsers.

24×7 Monitoring
NuSummit Cybersecurity extended Cyble dark web monitoring to 24×7, in collaboration with the client’s internal teams, improving alert response times.

The implementation required coordination between NuSummit Cybersecurity engineers and the client’s InfoSec, Infrastructure (Cloud and On-Prem), and Application teams. Challenges related to infrastructure alignment and complex application integrations were addressed through structured collaboration and regular working sessions.

Business Impact

100% Server Coverage
Complete SIEM integration for all critical assets.

89% MITRE Technique Coverage
