A Deeper Look at the Performance and Security Advantage of Threat Control for CloudFS

Panzura CloudFS Combines Real-Time, AI-Powered Threat Detection with Immutable File System Architecture to Ensure Data Is Always Secure and Recoverable 

Key Takeaways: 

• Traditional file data security approaches often create a trade-off between operational performance and protection, as they rely on resource-intensive scanning or require data to be sent to the cloud, causing lag and bottlenecks. 

• New AI-powered Threat Control in Panzura CloudFS uses a unique, ML-based behavioral fingerprinting approach to proactively detect threats like data exfiltration and mass deletions without impacting system performance or user experience. 

• This new capability, combined with CloudFS’s existing immutable data architecture, provides a “defense in depth” strategy that reduces complexity and costs by eliminating the need for separate security tools and ensuring business continuity with rapid recovery times. 

Ransomware and data exfiltration have exposed a significant vulnerability in traditional security strategies. When scanning inert data like backups, systems can afford to use significant processing power. Where active data is involved and users and processes require immediate file responses, a different approach is required. However, many legacy file systems, and even some modern file platforms, force IT decision makers to choose between security and operational performance, as well as introducing data privacy concerns.  

Platforms that rely on continuous, resource-intensive scanning of active data can heavily penalize file operations. Those that require complete file data to reach the cloud for analysis introduce a lag in reaction time as well as exposing file data itself to the analyzing engine. In short, while competitive solutions may offer various security features, their underlying architectures can introduce performance bottlenecks, especially when dealing with real-time threat detection and mitigation. 

An enterprise-grade hybrid cloud file system like Panzura CloudFS that manages mission-critical, sensitive data across the globe — allowing users to work from a single, highly secure, damage-proof data source — cannot accept a solution that slows down file operations, requires additional processing power, or exposes companies to data privacy risks. 

CloudFS now offers AI-powered Threat Control, driven by advanced ML analytics, which eliminates this compromise. This represents an important shift to a proactive security model that is  highly effective with no discernible impact on performance. 

The new CloudFS capabilities offer a unique approach, protected by patent-pending technology, for distributed threat detection and response that is designed from the ground up to deliver powerful protection without the usual performance tradeoffs or data privacy concerns. 

Behavioral Fingerprinting and Automated Response

The ML-powered engine behind CloudFS Threat Control is trained specifically on each customer’s own CloudFS environment, creating a unique behavioral fingerprint for every user. It learns what “normal” looks like for each individual, enabling it to instantly detect subtle but potentially problematic deviations. 

This behavioral analysis is a leap forward from traditional, signature-based detection, which is always one step behind adversaries. CloudFS can catch sophisticated attacks that don’t have a known signature by spotting unusual patterns such as: 

• Data Exfiltration: The platform instantly detects when large volumes of data are being accessed or moved in patterns unusual for a specific user. 

• Data Destruction: It recognizes suspicious deletion behavior, particularly mass deletions that are inconsistent with normal file handling. 

• Unusual Behavior: The system flags outlier events like bulk file creation, abnormal permission changes, or erratic access patterns that don't match established user behavior. 

This proactive detection dramatically reduces false positives, solving the problem of “alert fatigue” that plagues many IT teams. When a threat is detected, the automated response framework can instantly log incidents, notify administrators, and even disable compromised accounts. Response times are measured in seconds, not hours, eliminating the human delay that can cost millions in damages and recovery. 

Building “Defense in Depth” and Business Value

The new Threat Control capabilities, formerly called Detect and Rescue, build on CloudFS’s existing “defense in depth” architecture. The platform’s immutable data and snapshots, which provide a global recovery point objective (RPO) of under 60 seconds, ensure that even if a threat evaded detection, recovery points would not be destroyed. This layered approach is difficult for attackers to overcome. It also provides immediate operational advantages, as the “zero-touch” implementation requires no infrastructure changes, user disruption, or complex configuration. 

For IT leaders, this combination of performance and security translates to significant business value. It eliminates the need for separate security tools, reducing complexity, licensing costs, and administrative overhead. 

The ability to avoid costly and time-consuming recovery efforts means your team can focus on contributing to business value, not just reacting to threats. The new CloudFS capabilities help you get ahead of attacks, ensuring business continuity and a competitive advantage in a world where data loss can be catastrophic. 

How CloudFS Stacks Up

CloudFS is unique in that it avoids the performance-compromising methods of other solutions. Instead of relying on a single, resource-intensive approach, CloudFS uses a two-tiered system to monitor file activity without disrupting user workflows or compromising data privacy. 

For example, other file management solutions typically use more traditional threat detection methods involving either continuous, client-side scanning, or transporting file data to a centralized location for analysis. 

Nasuni may use a centralized, cloud-based platform for threat detection and data integrity checks, but this potentially leads to latency when analyzing files as they are being created or modified. Like CloudFS, Nasuni uses snapshots to provide reactive protection against ransomware. However snapshots are at the volume level rather than capturing the entire file system. Nasuni’s file data is typically moved to the cloud for analysis, which may create a potential performance bottleneck. 

CTERA may use endpoint agents and cloud services for data protection. Its approach can often involve continuous background scanning of files on local devices, which potentially consumes significant client-side resources and could slow down performance. The scanning process itself presents a possible performance drag on user machines. 

Egnyte offers various security tools, including content scanning and policy-based controls. These may involve heavy data processing on the client side or transporting data to the cloud for inspection, which can potentially impact performance and user experience, especially with large files or high-frequency file changes. 

As described above, the CloudFS architecture stands in stark contrast to less efficient, single-layer approaches. In those scenarios, every file event might require a computational check on the local machine or a transfer of data to a central location, leading to latency and poor user experience. With CloudFS, the monitoring is largely invisible and does not impact day-to-day operations. 

Existing Panzura CloudFS customers with Detect and Rescue, now renamed to Threat Control, will be upgraded to the enhanced capabilities at no additional cost and without requiring any action on their part including infrastructure changes or system downtime.
