Elastio and Halcyon
When Ransomware Bypasses Prevention Tools, Elastio Ensures Clean Recovery
Executive Summary
Elastio is an agentless, enterprise-wide provable recovery control that continuously validates backups and cloud storage to ensure ransomware-free recoverability within your SLA.
Halcyon is an endpoint-focused anti-ransomware agent that attempts to capture encryption keys in memory to decrypt files during an attack.
Use Halcyon as an endpoint rollback safety net. Use Elastio to prove recovery across your entire data estate and stop ransomware before it impacts backups and restores.

Technical Comparison
Technical Factor | Elastio | Halcyon |
|---|---|---|
Resistant to Per-File / Hybrid Encryption | ✓ Independent of ransomware scheme | ❌ Requires key capture per file in memory |
Detects Ransomware in Live Cloud Data | ✓ | ❌ |
Detects Ransomware in Backups | ✓ | ❌ |
Works Across All Backups, Workloads & Cloud Storage | ✓ | ❌ Endpoint-only |
Bypass Resistant | ✓ API/cloud integrated | ❌ Susceptible to kernel exploits |
Agent Stability | ✓ Agentless | ❌ Reported agent instability under load |
Recovery Method | ✓ Validated clean restore | ⚠️ Local decryption if keys captured |
Works if Data is Wiped/Deleted | ✓ Restore clean snapshot | ❌ No keys = no recovery |
Why Elastio
Elastio was built for the moment prevention fails. It continuously validates backups and live cloud data so CISOs and boards know recovery is possible, provable, and compliant.
- Sees All Your Data: Unlike endpoint agents, Elastio spans your entire data estate — applications, backups, and cloud storage.
- Provable Recovery Control: Every recovery point is pre-validated against ransomware, giving you a measurable SLA-backed security control.
- Zero-Day Resilience: AI models trained exclusively on ransomware detect new strains, including zero-days, before they compromise recovery.
- Agentless by Design: Deploys without agents, integrating seamlessly into cloud and backup platforms.
- The Last Line of Defense: When ransomware slips past perimeter and endpoint defenses, Elastio guarantees clean, provable recovery across your environment.
Why This Matters for CISOs & CTOs
- Regulatory Alignment – Elastio fills the compliance gap for backups and storage by adding the missing Detect/Recover controls. It enables organizations to prove recoverability under frameworks like NYDFS 500.16, DORA, and HIPAA, transforming recovery from a best effort into a validated control.
- Risk Register Coverage – Endpoint tools like Halcyon reduce breach likelihood on devices. Elastio reduces the business impact by continuously proving that backups and cloud data are intact, recoverable, and ransomware-free within SLA. This turns recovery into a measurable risk metric (R-RPO) for the enterprise risk register.
- Board-Level Assurance – After a ransomware incident, boards ask one question: “Can we recover?” Only Elastio provides auditable evidence that recovery is guaranteed, giving CISOs and CTOs the confidence to answer with proof, not hope.
Bottom Line
- Halcyon provides an endpoint rollback mechanism, but it is limited by ransomware encryption techniques (e.g., unique per-file keys), endpoint agent stability, and scope of coverage.
- Elastio, by contrast, delivers broader coverage and earlier detection by continuously scanning live cloud data and backups, and provides a provable security control that measures ransomware RPO and guarantees clean recovery within an SLA.
A layered defense is essential for true resilience. Elastio secures your entire data estate with provable, SLA-backed recovery, extending cyber resilience beyond the limits of endpoint-only tools.
Frequently Asked Questions (FAQ)
No. Elastio does not create or manage backups. It integrates with your existing backup and storage systems to validate the integrity of your data. Elastio ensures your backups are ransomware-free, so when you restore, you know it’s clean and provable.
