Rethinking data security from first principles

Most data security platforms today rely on a copy-first model, where data must be centralized before it can be analyzed. Historically, this architecture traces back to the early 2000s and the rise of log aggregation systems, which were designed to process massive volumes of small, lightweight data points.

Today, enterprise data security operates on a fundamentally different data unit, large files and petabyte-scale unstructured datasets, making that model a poor fit.

Copy first model

Centralized analysis fails for enterprise

Slow, costly, and forces coverage compromises – while continuously exposing sensitive data to third-party clouds

Zero copy data security

Secure enterprise data where it lives

Discover and control sensitive files directly where they reside, without ever duplicating or moving data to a third-party cloud for analysis.

Platform architecture

Cloud-managed control with in-place data processing at the source.

FAQ

Frequently asked questions

My current provider already finds sensitive data and manages risk. Why switch to Qostodian?
  • Data never leaves your environment: Qostodian analyzes and protects files in place – no copies, no 3rd party exports, and full data sovereignty.
  • Real-time remediation at the source: Fix issues directly on endpoints, servers, and cloud workloads without delays or workflow disruption.
  • Built for enterprise scale: Distributed edge compute delivers fast results across petabytes of data without performance tradeoffs.
  • Focus on the highest-impact risk: Prioritizes the small percentage of files that drive most of your data exposure to achieve measurable risk reduction fast.
  • Predictable, flat-rate pricing: Costs stay stable as your data grows – no volume fees, no consumption traps.

What does Qostodian detect and alert?

Qostodian detects and alerts on:

  1. Sensitive Data Overexposure
  2. Excessive Data Retention
  3. ROT Data Accumulation
  4. Suspicious behaviors: excessive file access, unusual sharing patterns
  5. High-risk employee activities
  6. Threshold alerts (when metrics exceed limits)

With the new addition of conditional workflows, users may setup alerts for a large variety of conditions.

What parameters can I use to monitor my users and their data?
  • Qostodian monitors sensitive data elements across more than 135 file extensions.
  • You can create custom rules to find specific data elements (e.g., a particular credit card number).
  • Qostodian can also detect custom data types and proprietary IP.
Do Qostodian agents consume a lot of resources?

Qostodian’s lightweight agents are aware of memory overhead and can be configured to consume resources dynamically.

Do I need any specific software to run Qostodian?

Qostodian is a cloud based service with agents designed to provide continuous monitoring for supported Windows and Linux file servers, workstations running Windows and MacOS, Microsoft 365, Google Workspace (soon), and AWS S3 (soon). The Qostodian platform itself is securely managed by Qohash with controlled access for authorized users. As long as your endpoints are functional, the platform can easily connect!

How long does it take to deploy to endpoints? (sensor only)

Deployment is fast – typically within a few hours.
Your desktop/server team deploys the sensor using your preferred tool (e.g., SCCM). Once activated, the sensor is configurable from the Qostodian dashboard. Proceed to scan and see match results populate in near real time!

What are the requirements of resources on the endpoint (workstations/servers)?

Recommended requirements:

  • OS: Windows 10 or 11 or MacOS (ARM chipset)
  • CPU: 2+ cores @ 2.40GHz + pageable RAM
  • Memory: 8GB+
  • CPU Architecture: 64-bit
  • Disk Space: 5GB available
  • Disk Throughput: 15,000 IOPS (60MB/s+)
While Qostodian monitors my sensitive data, will any data leave my environment?

No. Qostodian operates entirely within your environment. Qohash does not access your data, ensuring full data privacy and sovereignty.

What compliance standards does Qostodian support?

Qostodian supports comprehensive compliance management, including OSFI guidelines (B-10, B-13, E-13, E-21), and provides full audit trails to help meet regulatory requirements. Qohash is certified against major global standards (ISO 27001, ISO 27701, ISO 42001, and SOC 2 Type II) and helps organizations align with common data-protection and privacy regulations such as GDPR, CCPA/CPRA, HIPAA, PCI-DSS, Loi 25 and other industry-specific frameworks.

What level of remediation is natively supported, and is it truly automated?

Qostodian natively supports file actions (quarantine, delete, remove, restore), tagging (Qtags), and Microsoft Purview labelling. Additionally, our conditional workflows feature can automate these forms of remediation.

Do you offer training and support?

Yes – technical support, documentation, user training, certification programs, and elite customer success are always included with our solution. Visit our service desk for more information.
