Most recently, he served as Vice President and CISO at Nubank, overseeing information security, global IT and corporate security.

Halcyon, an anti-ransomware platform provider, has partnered with HYCU, a data protection company, to extend ransomware protection to cloud and hybrid environments. The collaboration integrates Halcyon's prevention capabilities into HYCU's R Shield solution, creating what the companies call the first ransomware-resilient data protection platform. The partnership addresses growing threats to cloud-hosted data across platforms including AWS, Azure, Google Cloud, VMware and Nutanix. Halcyon's technology detects and prevents ransomware early, triggering just-in-time HYCU backups to create clean restore points near the moment of attack whilst protecting backup environments from tampering. The integration aims to close gaps in traditional security strategies as organisations move critical workloads to the cloud, where ransomware operators increasingly target backup systems before launching encryption attacks.
HYCU expands R-Shield cyber resilience solution with halcyon to deliver the First Ransomware-Resilient Data Protection Solution. Enhancements to R-Shield deliver the industry's first unified approach to stopping ransomware, protecting backups, and ensuring rapid recovery across the entire data estate Boston, Massachusetts, March 31, 2026 (GLOBE NEWSWIRE) - HYCU, Inc., a leader for modern data protection for on-prem, cloud, and SaaS and one of the fastest growing companies in the industry, today announced a major expansion of its R-Shield cyber resilience solution through the integration of Halcyon's advanced ransomware prevention and data exfiltration capabilities. The announcement represents a watershed moment for the data protection industry, where true prevention and protection technologies will operate a coordinated system rather than as separate layers. This represents a significant step forward in delivering complete ransomware resilience across detection, prevention, and recovery for HYCU's global partners and customers. (See Related Release: Halcyon Partners with HYCU to Expand Ransomware Protection to Cloud Environments and Create the First Ransomware-Resilient Data Protection Solution.) "As AI makes attackers stronger, forward-thinking organizations have realized that they can no longer approach ransomware resilience with disconnected tools," said Enrique Salem, Partner, Bain Capital Ventures (BCV) and an investor in both HYCU and Halcyon. "With the combination of prevention, protection, and recovery in a single, coordinated system, these two purpose-built solutions are coming together to close a critical gap in enterprise security and giving organizations a more complete way to protect the full estate." HYCU R-Shield will enable organizations to identify ransomware threats earlier, disrupt attacks before they spread, and recover quickly if, and when, incidents occur. By combining Halcyon's purpose-built anti-ransomware technology with HYCU's protection of the entire data estate, customers gain a more complete and unified approach to cyber resilience. "True cyber resilience requires organizations to be ahead of threats at every stage, from early detection and active prevention through to fast, reliable recovery," said Simon Taylor, Founder and CEO, HYCU. "Our 2025 State of SaaS Resilience Survey found that nearly 80% of organizations experienced data loss or disruption in the past year, and more than half lacked confidence in their ability to recover quickly across all workloads. By integrating Halcyon's prevention capabilities with R-Shield, we are delivering a single, more complete resilience model, one that gives customers the assurance that ransomware threats can be identified early, stopped wherever possible, and recovered from rapidly when they occur." A Unified Approach to Ransomware Resilience The enhanced R-Cloud platform with R-Shield, with ransomware prevention powered by Halcyon, addresses this gap with the following three capabilities: Detect: Identifies ransomware behavior directly on endpoints and production workloads before backup data is impacted. Prevent: Stops ransomware activity, including encryption and exfiltration attempts reducing the number of attacks that can ever reach the backups. Recover: Enables rapid, application-centric recovery across hybrid and multi-cloud environments. This integrated approach allows organizations to move from reactive recovery to proactive resilience, reducing both the frequency and impact of ransomware incidents. "Organizations today face a growing gap between their confidence in ransomware preparedness and the reality of modern attacks, especially as more data moves to the cloud," said Jon Miller, CEO and co-Founder, Halcyon. "Our partnership with HYCU extends Halcyon's platform to protect these environments, delivering the resilience organizations need to prevent ransomware from running and to rapidly recover if an attack occurs." Designed for Resilience and Hybrid, Multi-Cloud Environments The expanded R-Shield solution addresses what has become one of the most pressing challenges for enterprise security and data protection teams, the inability of siloed tools to provide consistent, end-to-end protection coverage. By bringing Halcyon's prevention and exfiltration defense into the R-Cloud platform, HYCU delivers an integrated capability set that raises the bar for what data protection solutions must offer in an era of relentless ransomware. Additional Enhancements to R-Shield In addition to new capabilities powered by Halcyon available shortly, HYCU also recently added malware scanning for Amazon EC2 and Azure backups, helping customers confirm clean restore points and recover with confidence.
