The World's First Ransomware‑Activated Fuse
Detects ransomware behavior near instantly, severs the infected connection, and lets the rest of your organization keep working — no agents required.
- Isolates Infected Client From Storage Server
- Detects Suspicious Data Exfiltration Activity
- Agentless — Nothing to Install on Client Workstations
- Selectively Restore Any Files Encrypted Before the Fuse Trips
When Ransomware Strikes, SnapShield Strikes Back Faster.
For organizations handling mission-critical data, ransomware attacks pose a serious threat. They can cripple operations and bring business to a complete standstill. To guard against these threats, many rely on conventional security measures such as firewalls, endpoint protection, network monitoring, and backups. While these tools are important for defense, they cannot guarantee complete protection. If ransomware manages to get through, the damage can escalate quickly and severely.
SnapShield enhances protection by adding an extra layer of security beyond the status quo. Utilizing real-time behavioral analysis, it functions as a "ransomware-activated fuse". When it detects ransomware behavior, SnapShield severs the connection between the infected client and the storage server — like a fuse — while all other clients continue working normally. Because detection is near-instant rather than instantaneous, a small number of files may encrypt before the fuse trips. For those, SnapShield's built-in recovery tool lets you selectively restore individual files or entire batches.
How It Works
Detect. Isolate. Recover.
Detect
Behavioral analysis continuously monitors file write activity from every connected client in real time — no signatures required.
Isolate
The moment ransomware behavior is detected, SnapShield severs the connection between the infected client and the storage server, while all other clients continue working normally.
Recover
SnapShield acts near-instantly, keeping file damage limited. Any files encrypted before the fuse trips can be selectively rolled back to clean versions through the SnapShield UI.
How SnapShield Compares
'Status Quo' Security

What Makes SnapShield Unique?
SnapShield acts like a ransomware-activated fuse. The moment it detects suspicious behavior, it severs the connection between the infected client and the storage server — while everyone else keeps working uninterrupted.
Agentless — Installed on the storage server. No software required on individual workstations.
Behavioral detection — Monitors file access patterns in real-time, not known malware signatures.
Targeted isolation — Only the infected workstation is disconnected. The rest of your network stays online.
Fast, selective recovery — Because detection is near-instant, a small number of files may encrypt before the fuse trips. For those, SnapShield's built-in UI lets you selectively roll back individual files or entire batches to clean versions.
Introducing SnapShield, the World's First Ransomware-Activated Fuse
Watch as 45Drives Technical Lead Brett Kelly and Chief Solutions Architect Mitch Hall walk through how SnapShield defends your critical data infrastructure against ransomware threats.
In this video, they break down the technology behind SnapShield, explain its role in a layered security strategy, and demonstrate its ransomware-activated fuse in a live, real-world scenario. If you're looking to strengthen your organization's ransomware defenses, this is a must-see.
See SnapShield in Action
At 45Drives, we offer education to help users get the most out of their storage and virtualization environments, with a focus on performance, security, and real-world application.
In this demo, you will discover how SnapShield protects your organization against ransomware attacks. We run simulated ransomware, including strains like LockBit, in a controlled and isolated environment so you can see exactly how SnapShield detects malicious behavior, severs the connection to the infected client, and prevents damage from spreading across your network.
You will also see how easy it is to recover encrypted files through the SnapShield user interface, demonstrating how quickly operations can return to normal.
Bill Hopkins: City of Keizer
After the City of Keizer, Oregon, was hit by a devastating ransomware attack in 2020, Head of IT Bill Hopkins knew stronger protection was needed. That realization led him to implement SnapShield, which has since helped keep the city safe from further ransomware threats.
To hear more about how SnapShield has protected the City of Keizer's data, listen to Bill's story on the 45Drives podcast, What's Spinnin'.
