Case Study: Empowering an Oil & Energy Company to Mitigate Risk and Reduce Cyber Insurance Costs

Background
A leading oil and energy company operating upstream exploration sites and downstream refining facilities faced escalating cyber threats targeting its complex operational technology (OT) and IT networks. Managing critical infrastructure across remote locations and integrating legacy systems with modern cloud services increased the risk of operational disruption and data compromise.

With increasing regulatory scrutiny and industry-specific compliance requirements, the company struggled to maintain consistent, comprehensive security coverage.

Challenge
The company needed a comprehensive, real-time security solution that could:

  • Continuously monitor OT control systems, corporate IT networks, and cloud infrastructure.

  • Detect vulnerabilities, misconfigurations, and malicious activity across geographically dispersed assets.

  • Provide immediate automated threat detection and response aligned with energy sector regulations.

Existing security solutions operated in silos and generated overwhelming alerts without clear prioritization. Meanwhile, escalating cyber insurance premiums added financial strain, limiting investment in technology modernization.

Solution
By partnering with Antigen Security, the company deployed an integrated cybersecurity platform designed specifically for the oil and energy sector:

  • Continuous scanning and real-time visibility into OT environments, IT systems, and cloud assets—ensuring comprehensive coverage of all critical infrastructure.

  • Customized threat detection rules to identify indicators of compromise in SCADA systems, pipeline controls, and energy management platforms.

  • Automated remediation workflows aligned with industry standards such as NERC CIP and API security guidelines to minimize operational impact.

Antigen Security also collaborated with insurers to demonstrate the company’s improved security posture, supporting favorable insurance renewal terms.

Results

Streamlined Security Operations:
The unified dashboard provided clear visibility across OT and IT environments, reducing alert noise and enabling rapid response to genuine threats.

Improved Risk Posture:
Real-time monitoring and automated incident response enhanced operational resilience and regulatory compliance, reducing the likelihood of costly service interruptions.

Significant Premium Savings:
With demonstrable risk reduction, the company achieved a 47% decrease in cyber liability insurance premiums, freeing capital for strategic investments in safety and innovation.

Conclusion
Thanks to Antigen Security’s specialized cybersecurity platform and insurer-aligned approach, this oil and energy company strengthened its defenses against evolving cyber threats while lowering insurance costs. By integrating continuous monitoring, tailored threat detection, and automated remediation, Antigen Security became a vital partner in safeguarding critical energy infrastructure and supporting business continuity.
