[01]Business ContextTHE CLIENT · THE LANDSCAPE

An international energy provider under persistent APT pressure

The client is an international energy company recognized for large-scale operations across energy generation, distribution, and customer services. Facing persistent, highly sophisticated cyber attacks from governmental Advanced Persistent Threat (APT) actors, the organization recognized that its existing security operations lacked the advanced detection capabilities and continuous oversight required to effectively identify and neutralize stealthy, state-sponsored adversaries.

Key Context
Persistent attacks from governmental APT actors with significant resources
Existing SIEM solution lacking advanced detection capabilities
Critical infrastructure at severe risk from prolonged undetected compromise
Need for continuous, round-the-clock monitoring of network and systems
[02]Client NeedsREQUIREMENTS · OBJECTIVES

What prompted the project

To bolster their cybersecurity posture, the energy company required a premium Managed SOC service capable of proactively defending their network — replacing their existing inefficient setup with continuous, expert-led monitoring and rapid response.

N/01

Modernized SIEM Solution

Replace the current, inefficient SIEM solution with a modernized system capable of advanced threat detection against state-sponsored adversaries.

N/02

24/7 Continuous Monitoring

Continuous, round-the-clock monitoring of their entire network and systems to detect anomalies instantly — not a 9-to-5 coverage model.

N/03

Custom APT Detection Rules

Advanced, customized capture rules specifically designed to identify malicious activities and APT attack patterns that generic rules miss.

[03]The ChallengesPRE-PROJECT · EXECUTION

Why an expert partner was required

Failing to intercept governmental APT threats posed a severe risk to the company's critical infrastructure, potentially leading to operational disruptions and data compromise.

Pre-Project ChallengeAdvanced Persistent Threats
State-Sponsored Actors
The attackers were highly sophisticated governmental APTs with significant resources, patience, and access to zero-day tooling.
Stealthy Operations
APT actors use stealthy techniques designed to evade conventional security monitoring and blend in with legitimate traffic.
Impact
Existing tools lacked the capability to detect these advanced, patient adversaries before they achieved their objectives.
Pre-Project ChallengeInefficient SIEM
Outdated Detection
The current SIEM solution lacked advanced detection capabilities required for APT identification.
Limited Visibility
Insufficient oversight of network and systems created blind spots that APTs could exploit for months at a time.
Impact
Critical infrastructure was vulnerable to prolonged undetected compromise with no clear containment playbook.
Pre-Project ChallengeCritical Infrastructure Risk
Operational Disruption
A successful attack could lead to operational disruptions affecting energy supply to millions of customers.
Sensitive Data Exposure
Highly sensitive operational, customer, and strategic data could be compromised by sophisticated adversaries.
Impact
The stakes were extraordinarily high — requiring immediate, expert intervention with proven capabilities.
[04]Solutions ProvidedARCHITECTURE · IMPLEMENTATION

What We As Web delivered

WE AS WEB implemented a comprehensive Managed SIEM SOC service that delivered continuous monitoring, advanced threat detection, and rapid incident response capabilities.

S/01

Dedicated Continuous Monitoring

A dedicated SOC team operating 24/7 — providing true round-the-clock coverage of the company's network and systems.

We established a dedicated SOC team operating around the clock, providing continuous oversight of the company's network and systems.
Anomalies are detected instantly, enabling rapid response before significant damage occurs — no after-hours gaps.
S/02

Advanced Threat Detection Rules

Customized capture rules specifically designed for APT attack patterns, with continuous tuning as the threat landscape evolves.

Our security engineers developed customized capture rules specifically designed to identify malicious activities and advanced threats.
Because APT tactics evolve, these rules are regularly analyzed and fine-tuned based on shifting attack patterns.
S/03

Robust Incident Response Playbooks

Structured, tested workflows that ensure rapid, coordinated containment when a threat is detected.

We created and implemented highly effective incident response playbooks and protocols for the most likely APT scenarios.
These structured workflows ensure that when a threat is detected, the team can rapidly respond to minimize the impact.
S/04

[07]ConclusionSUMMARY · NEXT STEPS

When APT attacks target critical infrastructure

When an energy provider is actively targeted by governmental APTs, an inefficient SIEM solution is a critical liability. By deploying a premium, 24/7 Managed SOC equipped with continuously tuned capture rules and rigorous incident response playbooks, we provided this international energy company with the proactive defenses it needed.

The result is a hardened, highly monitored digital environment where advanced threats are detected and contained before they can impact critical infrastructure. The continuous optimization of detection rules ensures the organization remains protected against evolving APT tactics.
