Overview

A Scandinavian energy provider operating across Norway and Denmark needed stronger protection for critical infrastructure. Krish Services Group built a unified IT-OT SOC to monitor cyber threats across enterprise and industrial systems. The solution improved threat detection, response coordination, and regulatory readiness while supporting safe, reliable energy operations across borders.

Client Background

The client is a large energy utility managing power generation and transmission assets across Scandinavia. Its operations include grid systems, hydro assets, and industrial control environments. As cyber risks increased, especially against national infrastructure, the organization required a centralized security model that connected IT, OT, and compliance under one operational framework.

Challenges

• Advanced Threats to Industrial Systems: Legacy SCADA and OT environments lacked modern monitoring, increasing exposure to cyber intrusions targeting critical energy infrastructure.

• Disconnected IT and OT Monitoring: Separate security teams and tools reduced visibility, delaying threat correlation between enterprise systems and industrial networks.

• Complex Regulatory Requirements: Compliance with energy and cybersecurity standards required specialized reporting, incident response processes, and audit-ready controls.

Solutions 

• Unified IT-OT SOC Model: Deployed a cross-domain SOC with OT specialists, SOC analysts, and compliance oversight for coordinated threat monitoring.

• Industrial-Aware Security Technology Stack: Implemented SIEM, endpoint security, ICS monitoring, and automation tailored for both IT and OT environments.

• Standardized Incident Response Processes: Developed NIST-aligned playbooks and conducted regular security testing to validate OT segmentation and response readiness.

Business Value Propositions

• Early Detection of OT Security Incidents: Identified and contained suspicious industrial network activity within hours, reducing risk to critical operations.

• Improved IT-OT Collaboration: Shared playbooks and drills improved coordination between enterprise and industrial security teams.

• Stronger Compliance and Resilience: Enabled real-time monitoring and automated reporting to support regulatory audits and infrastructure protection.

Final Perspective

Krish Services Group helped the energy provider secure critical infrastructure by unifying IT and OT security operations. The centralized SOC improved visibility, response speed, and compliance, enabling safer and more resilient energy delivery across national boundaries.

Overview

A mid-sized financial institution in Sweden faced increasing cyber risks and stricter European regulatory requirements. We designed and deployed a full-scale Security Operations Center (SOC) with defined processes, tiered analyst teams, and continuous monitoring. The SOC improved threat detection, reduced response delays, and gave leadership better visibility into security posture while supporting ongoing compliance and business growth.

Client Background

The client is an established financial services organization in Sweden offering retail banking, credit, and fintech solutions to consumers and small businesses. As digital adoption increased, the attack surface expanded and regulatory expectations intensified. To protect customer data and maintain trust, the organization needed a centralized cybersecurity operations model aligned with European compliance standards.

Challenges

• Absence of Centralized Security Monitoring: The organization lacked a unified SOC capability, limiting real-time threat detection, alert triage, and coordinated incident response across systems.
• Expanding and Evolving Threat Landscape: Rapid cloud adoption and remote work increased exposure across endpoints, identities, and email systems, raising overall cyber risk.
• Growing Regulatory and Compliance Expectations: European financial regulations required measurable incident response metrics, audit-ready processes, and continuous visibility into security operations maturity.

Solutions

• Multi-Tiered SOC Operating Model: Implemented tiered SOC teams with global coverage, enabling continuous monitoring, faster escalation, and consistent incident handling.
• Integrated Security Technology Stack: Deployed SIEM, endpoint detection, SOAR automation, and threat intelligence integrations to improve visibility, correlation, and response accuracy.
• Standardized SOC Processes and Governance: Established runbooks, performance metrics, and maturity assessments to ensure repeatable operations and continuous SOC effectiveness improvements.

Business Value Propositions

• Rapid Incident Detection and Containment: The SOC contained a business email compromise within 2 hours, minimizing potential financial and operational impact.
• Post-Incident Security Policy Strengthening: Strengthened MFA, email security, and user awareness reduced the likelihood of repeat incidents.
• Enterprise-Wide Security Readiness: The SOC became a core control for consistent threat response and financial risk management.
