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.

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.

The cybersecurity industry's heavy reliance on endpoint detection and response tools has created significant vulnerabilities, particularly around IoT devices and operational technology that cannot be monitored using traditional security tools, according to Vincent Stoffer, field CTO at Corelight. This growing attack surface, combined with sophisticated threat actors who exploit any available entry point, has pushed organizations to reevaluate their security strategies and consider more comprehensive network monitoring approaches.
