Halcyon
Ransomware is not a threat your existing security stack was built to stop. Halcyon is.
Overview
Every organisation running endpoint detection and response tools, next-generation antivirus, and email security believes it has ransomware covered. The ransomware groups targeting UK organisations today are counting on exactly that belief.
Ransomware attacks against UK organisations increased by 70% in the past year. The average ransom demand against a UK business now exceeds £800,000. And the majority of successful ransomware attacks are executed against organisations that had security tools in place, tools that were bypassed, evaded, or rendered irrelevant by adversaries who study defensive technology with the same rigour that defenders study threats.
The problem is not the absence of security investment. It is the assumption that general-purpose security tools provide specific protection against one of the most sophisticated and financially motivated threat categories in existence.
The reality is most of the time they don’t.
The organisations that discover this through a live ransomware incident pay a price that goes far beyond the ransom itself.
Halcyon was built to solve a problem that the rest of the security stack cannot. It is the only platform purpose-built for ransomware prevention, resilience, and recovery. When deployed and managed by Cyberfort, it represents the most significant reduction in ransomware risk available to UK organisations today.

What is Halcyon and how does it protect organisations against ransomware attacks?
Halcyon is the only security platform architected from first principles around a single, specific objective: preventing ransomware from succeeding – not merely detecting it, not alerting on it, not documenting it after the fact, but actively preventing encryption from completing even when every other layer of defence has failed.
The platform operates across four distinct defensive layers, each designed to address a specific stage of the ransomware kill chain.
Pre-execution prevention identifies ransomware payloads before they execute, using purpose-built detection logic trained exclusively on ransomware behaviour rather than the broad-spectrum detection approaches of general-purpose EDR platforms. Because Halcyon’s detection models are built around ransomware specifically, they identify evasion techniques and payload characteristics that general-purpose tools miss.
Anti-evasion and resilience address the core capability gap in existing defensive architectures – the evasion techniques that allow ransomware payloads to operate within the blind spots of EDR and antivirus platforms. Halcyon’s anti-evasion layer operates independently of signature-based and behavioural detection models, providing a defensive capability that remains effective against novel payloads and zero-day ransomware variants.
Ransomware process interruption operates at the speed ransomware requires. When ransomware execution is detected, Halcyon interrupts the encryption process autonomously, without waiting for human intervention, without requiring an analyst response decision, and without the latency that renders human-in-the-loop containment processes inadequate against a threat that operates at machine speed.
Key capture and autonomous recovery is the capability that separates Halcyon from every other platform in the market. In the event that encryption does occur, Halcyon captures the encryption keys generated by the ransomware process, enabling autonomous recovery of encrypted files without paying a ransom, or relying on potentially compromised backups, and without the extended recovery timelines that make ransomware incidents so operationally catastrophic.
Together, these four layers create a defensive architecture that addresses ransomware at every stage of the kill chain and provides a genuine recovery capability that makes paying a ransom operationally unnecessary rather than financially inadvisable.
Why Halcyon requires Cyberfort expertise to deploy and manage
Halcyon is a transformative platform. Like every transformative platform, its value is entirely dependent on the quality of its deployment, configuration, and ongoing management.
Ransomware defences that are incorrectly deployed are defences that fail at the worst possible moment. The deployment decisions that determine whether Halcyon provides genuine protection – policy configuration, integration with your existing security stack, exclusion management, alert threshold calibration, and response workflow design, all require deep expertise in both the platform and the ransomware threat landscape it is designed to address.
Beyond deployment, ransomware defence is not a set-and-monitor capability. It is a continuous management discipline. Ransomware groups actively research defensive platforms and develop evasion techniques against specific configurations. The threat intelligence required to stay ahead of those developments including understanding which groups are targeting your sector, what techniques they are currently deploying, and how your Halcyon configuration needs to evolve in response is a specialist function that requires continuous investment in threat research that most internal security teams cannot sustain alongside their operational commitments.
When a ransomware incident occurs, because no defensive architecture is perfectly reliable, and because the volume and sophistication of attacks means that incident response capability is as important as prevention capability the speed and quality of the response needs to be decisive.
Cyberfort’s delivery of Halcyon provides all of this – expert deployment, continuous management, proactive threat intelligence integration, and a rehearsed, rapid incident response capability, as a managed service that operates continuously, at the speed ransomware requires, without the operational overhead of building and sustaining this capability internally.
Start with a Ransomware Resilience Assessment
We offer a complimentary Ransomware Resilience Assessment for IT Directors and CISO’s who want an independent, expert view of how their current security architecture would perform against the ransomware techniques being used against UK organisations today.
In a focused 45-minute session, we will examine your current defensive stack, identify the specific gaps that ransomware groups targeting your sector are most likely to exploit, assess your backup and recovery capability against ransomware-specific attack patterns, and give you a clear view of what Halcyon would change.
Book your Ransomware Resilience Assessment by emailing us at [email protected] and one of our experts will be in touch.
