How Halcyon Works
Our anti-ransomware technology takes an end-to-end approach to proactively disrupt threats at every stage of the attack lifecycle, from pre-execution to data exfiltration and encryption. With an included 24/7 expert team that investigates and responds to threats for you, Halcyon ensures no ransom is paid and no downtime is tolerated.
End-to-End Ransomware Protection
Halcyon breaks the ransomware attack chain, providing a complete defense to protect your business.
Let’s Dispel Some Ransomware Fallacies
Ransomware isn’t as simple as a file or a label. It is not a specific malware classification. It is not just an executable encrypting files. It is not a single type of detection or alert. It’s a coordinated attack strategy, involving multiple stages, actors, and tools.
Ransomware has Become an Ecosystem
It’s not a lone hacker in a hoodie. Modern Ransomware Ops run like businesses, complete with: Initial Access Brokers, RaaS operators, affiliates, developers, and even pen testers. Each player has a role. Each role profits from your vulnerability.
One Executable?
Try an Entire Playbook.
Ransomware is not a singular tool or a one-time event. it has evolved into a coordinated, systematic, multi-stage campaign. From initial access to lateral movement, encryption, and extortion — every step is planned, executed, and profit-driven.
How it Works Across the Attack Chain
Key Features
Halcyon uses AI and behavioral engines to proactively disrupt ransomware and rapidly isolate attacks, capturing encryption keys to recover data. Supported by a 24/7 ransomware SOC, Halcyon ensures threats are detected, defeated, and your business stays protected and operational.
AI Engine
We detect indicators of ransomware with AI models exclusively trained on ransomware signals, based on millions of data points from active TTPs, samples, playbooks and real-world ransomware incident response engagements.
Behavioral Engine
Ransomware tactics can commonly bypass even the best detection engines. Halcyon’s behavioral engine harnesses threat modeling, anti-detonation and deception exploitation, tricking ransomware into providing additional indicators of compromise for higher accuracy and faster detection time.
EDR Tamper Detection
One of the first things ransomware attackers often do is tamper with EDR tools to evade detection. Disabling EDR and EPP tools quickly expedites the deployment of ransomware tools and increases the dwell time until discovery. Halcyon monitors EDR activity to detect and notify on the evasion and disabling of EDRs.
Bring Your Own Vulnerable Driver (BYOVD)
Kernel guard protection defeats the use of signed-but-vulnerable drivers (Bring Your Own Vulnerable Driver “BYOVD” Attacks), which can create exploitation points of entry into your environment, ensuring bad actors cannot exploit this inherent trust to carry out their objectives.
Data Exfiltration Protection (DXP)
Modern ransomware attackers not only encrypt data, but also exfiltrate sensitive information from the target, then demand that victims pay up to prevent them from publishing their data online. Using both nefarious peer detection and volumetric detection, DXP detects and reports on unusual data movements within a 24-hour period, including unauthorized file-sharing services, cloud tunneling, and known malicious command-and-control infrastructure.
Key Material Capture & Decryption
Halcyon captures the symmetric encryption keys ransomware uses to lock files and, capitalizing on our agent, quickly decrypts impacted data, even if the ransomware bypasses EDR and Halcyon, restoring files to their original state quickly.
Ransomware Detection & Recovery (RDR)
Our team of ransomware analysts provides around-the-clock monitoring and real-time threat response, acting as an extension of your security team. We fine-tune detection to minimize false alarms and deliver instant, expert analysis of threats and reverse engineering of encryption keys creating real-time fleet inoculation-based protection.
