Overview

Reducing alert overload and false positives for a leading North American energy company. HCLTech enhances the effectiveness of Security Information and Event Management (SIEM) and provides 24x7 Security Operations Center (SOC) services for continuous protection.

The client faced a high volume of security alerts, making threat investigation time-consuming and inefficient. Despite significant effort, many alerts turned out to be false positives, delaying response to real threats and increasing operational risk.

The Objective

To overcome these challenges, the client aimed to:

Enhance grid and corporate security
Proactively identify and neutralize threats before they escalate
Detect compromises in third-party vendor systems that could impact their own security

Additionally, the client gained strategic and tactical access to HCLTech’s security expertise, research and knowledge-sharing resources.

The Impact

Continuous protection and measurable results

Enhanced grid and edge security
