Key Takeaways

  • The SnapShield platform expanded to detect suspicious file-reading behavior associated with data exfiltration, not only ransomware encryption.
  • A new Centralized Management System gives enterprises and MSPs one interface for monitoring deployments across servers, sites, and customer environments.
  • Server-side isolation and Precision Restore are intended to contain compromised clients while preserving unaffected operations and files.

45Drives has expanded SnapShield with Data Exfiltration Protection and centralized management, extending the product from ransomware encryption detection into broader storage-level defense. Announced September 14, the additions address a basic shift in ransomware economics: attackers increasingly steal information before encrypting systems, or skip encryption entirely.

That change matters because restoring files does not undo a data leak. According to the ENISA Threat Landscape 2025, ransomware was involved in 81.1% of EU cybercrime incidents against organizations, while 68.6% of recorded intrusions resulted in data being leaked or sold on criminal forums. Separately, the Sophos State of Ransomware 2025 found that data-theft-only attacks, without encryption, tripled to 12% of cases in 2025.

While endpoint security, firewalls, and network monitoring can reduce risk, attackers frequently breach shared storage environments regardless of perimeter defenses, requiring automated responses at the storage layer itself.

SnapShield is designed to respond at the storage server. 45Drives describes the underlying mechanism as a ransomware-activated fuse. The product analyzes behavior in real time and, when activity crosses configured thresholds, can sever a suspected client’s connection to the server. Other users and systems can continue operating rather than losing access to the entire storage environment.

“Traditional cybersecurity defenses remain essential, but no organization should build its security strategy around the assumption that ransomware will never get through them,” said the company's founder. “The critical question is what happens when an attacker actually reaches the data.”

The new Data Exfiltration Protection feature applies that containment model to suspicious reading, rather than focusing only on abnormal file modification or encryption. SnapShield monitors sudden increases in file access and interactions with honey files, which are sensitive-looking decoys that legitimate users would not ordinarily open.

If behavior reaches an administrator-defined threshold, SnapShield can generate an alert or automatically isolate the associated user or IP address. This could give security teams an opportunity to intervene while collection is underway, although effectiveness will depend on threshold tuning, normal workload patterns, and how quickly an attacker moves data.

That said, behavioral controls create an operational balancing act. A legitimate analytics job, migration, or bulk backup might produce an unusual access spike. Enterprises evaluating SnapShield will likely want to test automated isolation policies carefully, establish escalation procedures, and determine which workloads merit alert-only treatment.

The company is also adding a Centralized Management System. It consolidates SnapShield instances, active events, user activity, analytics, and audit logs into one interface, with the ability to drill into an affected system. The change is particularly relevant to MSPs overseeing separate customer environments and enterprises with storage distributed across locations.

Without a shared console, administrators may need to inspect deployments individually during an incident. Centralized visibility can shorten that navigation process and support more consistent monitoring. It also raises practical governance questions around tenant separation, administrative privileges, and retention of security logs, areas prospective MSP users will want to assess during deployment planning.

SnapShield is agentless, requiring no software installation on individual workstations. It supports Rocky Linux and Ubuntu environments, including single-server installations and multi-node Ceph clusters deployed through an Ansible playbook. Email and system notifications provide real-time warnings.

Containment is paired with Precision Restore. After ransomware activity is detected, administrators can review which files were affected and selectively roll back damaged data while leaving unaffected files intact. That is a more targeted recovery model than restoring an entire volume, particularly when SnapShield interrupts activity early.

The approach complements, rather than replaces, immutable backups and recovery products offered by Rubrik, Cohesity, and Veeam. It also fits the lateral-movement restrictions described in NIST’s Zero Trust Architecture and the exfiltration behaviors cataloged by MITRE ATT&CK. Recent CISA and FBI ransomware guidance further reflects the continuing threat to organizations and critical infrastructure.

The expansion moves SnapShield closer to a combined detection, containment, and recovery layer for shared storage. Its value will rest on how accurately it distinguishes hostile activity from legitimate high-volume access, and how comfortably enterprises and MSPs can operationalize automated isolation across distributed environments.
