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.
