Halcyon

Halcyon is a specialized cybersecurity platform built exclusively to defeat ransomware. It provides a ransomware-native defense layer that detects, disrupts, and intercepts attackers at every stage of the kill chain—from pre-execution to data exfiltration to encryption. The platform includes key capabilities like File Resilience to block encryption, Double Extortion Prevention to stop data theft, and EDR Tamper Protection. The core offering is the Halcyon Anti-Ransomware Platform, backed by the world's first 24/7 Ransomware Operations Center (ROC). This expert-led team monitors, responds, evicts attackers, and manages recovery. The solution includes a ransomware warranty and is designed to supplement existing EDR and backup solutions, ensuring business continuity and rapid recovery.

Why Bath & Body Works Chose Halcyon for Ransomware Protection
Why Bath & Body Works Chose Halcyon for Ransomware Protection: Tony Hudson, Director of Security at Bath & Body Works, breaks down their cybersecurity strategy and why they needed something beyond traditional endpoint detection and response. They needed specialized ransomware defense. The Challenge: - Traditional EDR solutions weren't enough - Need for specialized ransomware recovery capabilities - Proving ROI on security investments Why Halcyon Stood Out: - Unique detection signatures that other tools miss - Specialized approach built specifically for ransomware - Recovery capabilities that minimize downtime costs Key Insight from Tony: "We use Halcyon's detections as a starting point for threat hunts because it catches things other security solutions don't detect." The Bottom Line: In retail, every minute of downtime has a real dollar cost. When you can put actual numbers to recovery time, the ROI becomes crystal clear. Tony's Suggestion to Security Leaders: Do a kill chain analysis. Most existing solutions won't prevent or help you respond to modern ransomware threats. The threat landscape has evolved. Your defenses should too. Our mission at Halcyon is to protect your organization against ransomware. Schedule a demo with us at https://halcyon.ai to learn more.
