Inside the SectorCERT Denmark Attack: How Corelight Helped Stop a Coordinated Campaign

Corelight CEO Brian Dye recounts how Corelight supported SectorCERT—an alliance of energy companies in Denmark—during one of the most advanced attack sequences he’s seen. The coordinated campaign targeted a shared firewall vulnerability across nearly a dozen organizations. Corelight provided the critical visibility and detection that helped defenders stop the first wave—and stay ahead of a second, modified attack just weeks later. The incident became a model of collaboration and response across national infrastructure.

How Corelight Helped a Customer Reject a $10M Ransomware Demand

Corelight CEO Brian Dye shares the high-stakes story of a customer under a $10 million ransomware attack. The attackers claimed to have stolen sensitive IP—but with Corelight, the customer had the network visibility to verify exactly what was taken. The result? They confirmed the stolen data was limited and non-critical, enabling them to confidently deny the ransom demand. This powerful story illustrates the difference between “I think” and “I know”—and how that clarity can drive executive confidence, legal defensibility, and real-world savings.

Web Application Firewall (WAF) Best Practices For Optimal Security

Web and mobile application code protection is a must-have security control. Modern solutions such as application layer firewall help your organisation to keep those assets protected from threats like SQL injection, cross-site scripting and bot-driven attacks. This is where a Web Application Firewall (WAF) comes into the picture. A WAF has the capability of filtering, monitoring and blocking HTTP requests to protect the assets from malicious requests without affecting legitimate users.

How to Fix the Challenges with Web App Firewalls

How to Fix the Challenges with Web App Firewalls Is your WAF enough? A10 experts Jamison Utter and Gary Wang delve into advanced security strategies that surpass traditional web application firewalls (WAFs). In today’s ever-evolving threat landscape, organizations face numerous security challenges that necessitate a shift from conventional WAFs to next-generation solutions.

Corelight Recognized as a Leader in the 2025 Gartner Magic Quadrant for Network Detection and Response

Network Detection and Response (NDR) has emerged as a must-have capability of modern security operations (SecOps). NDR provides deep visibility, detection of advanced threats that evade other security tools, and rapid response capabilities to address the SecOps challenges of incomplete visibility, detection gaps, high SIEM and storage costs, and tool sprawl that impact accuracy, speed, and efficiency.

One Platform, Total OT Protection: Cato's Response to CISA's Mitigation Guidelines

It started with a sudden alteration in chemical levels in the water treatment system. When a threat actor adjusted the level of sodium hydroxide to more than 100 times its normal amount, millions were at risk of being poisoned. Luckily, it was stopped in time. This is not fiction. It is one of several real incidents already published in 2021. Since then, more incidents have been identified, targeting critical water facilities and other OT infrastructure.

Why Risk Management is Now a Strategic Imperative for IT Leaders-and How Network Digital Twins Can Help

In 2025, risk management has climbed near the top of the CIO agenda—second only to AI adoption, according to the 2025 State of the CIO report. As global enterprises become more dependent on digital infrastructure, the consequences of network outages, misconfigurations, or security breaches have grown exponentially. CIOs, CISOs, and their teams now face the dual challenge of managing risk while enabling innovation.

Achieving PCI DSS v4.0.1 Certification: A Comprehensive Overview of Cato Networks' PCI Journey

As previously noted, we achieved PCI DSS v4.0.1 compliance certification, becoming the first SASE platform provider to do so. This milestone reflects our commitment to the highest security standards, ensuring enhanced protection for sensitive data. Throughout the assessment, we collaborated with an external Qualified Security Assessor (QSA) from USD AG to ensure all requirements were thoroughly evaluated.

Layer 7 DDoS Attack Methods

A10 Networks' security experts Jamison Utter and Carlo Alpuerto delve into comprehensive DDoS protection. In this segment, Carlo Alpuerto explains how attackers exploit Layer 7 DDoS methods, such as slow POST attacks and other slow-rate techniques (potentially referring to "slow patches" or similar application-layer attacks), to disrupt services. Whether you're a security professional, network administrator, or business leader concerned about cyber resilience, this expert conversation provides actionable insights to strengthen your organization's DDoS protection posture.
