Formed in 2021 by cybersecurity professionals (and backed by high-powered VCs including Dell Technologies Capital), [1]Halcyon sells an enterprise-grade anti-ransomware platform.

And this month they announced they're offering protection against ransomware attacks targeting Linux systems, [2]according to Linux magazine :

> [3]According to Cynet , Linux ransomware attacks increased by 75 percent in 2023 and are expected to continue to climb as more bad actors target Linux deployments... "While Windows is the favorite for desktops, Linux dominates the market for supercomputers and servers."

Here's how Halcyon's announcement [4]made their pitch :

> "When it comes to ransomware protection, organizations typically prioritize securing Windows environments because that's where the ransomware operators were focusing most of their attacks. However, Linux-based systems are at the core of most any organization's infrastructure, and protecting these systems is often an afterthought," said Jon Miller, CEO & Co-founder, Halcyon. "The fact that Linux systems usually are always on and available means they provide the perfect beachhead for establishing persistence and moving laterally in a targeted network, and they can be leveraged for data theft where the exfiltration is easily masked by normal network traffic. As more ransomware operators are developing the capability to target Linux systems alongside Windows, it is imperative that organizations have the ability to keep pace with the expanded threat."
