Infrastructure Security

Control Status
Physical Access Control - Data Center Bluur® operates on OVHcloud data center infrastructure that meets strict regulatory and industry requirements. This means our customers' data is processed in an environment compliant with international standards for security, privacy, and availability.
✓
Multi-tenant Architecture BTC operates on a multi-tenant architecture, where customer environments are logically isolated to ensure data privacy and security.
✓
Availability and Redundancy Designed with high availability and redundancy in mind to ensure service continuity and minimal downtime, the Bluur® platform is hosted in an OVHcloud data center located in Ożarów Mazowiecki (Kazimierza Kamińskiego 6, 05-850 Ożarów Mazowiecki, Poland). The facility is operated by OVHcloud sp. z o.o. and holds, among others, ISO 27001, ISO 27017, ISO 27018, ISO 27701 certifications, as well as SOC 1/2/3 standards (status as of 13.11.2025).

Bluur® uses load balancing modules to efficiently distribute traffic, optimize performance, and maintain service stability under varying loads. Redundant systems and infrastructure minimize the impact of potential failures. Together, these measures create a resilient platform customers can rely on, ensuring uninterrupted access and consistent performance.
✓
Vulnerability Scans BTC performs continuous vulnerability scanning to identify and remediate security issues.
✓

Application and Development Security

Control Status
Change Management BTC follows a structured change management process ensuring all updates, configurations, and changes to its production and corporate environments are reviewed, tested and securely implemented to minimize risk and uphold security integrity.
✓
Penetration Testing BTC conducts annual applicative penetration testing through an independent third-party provider.
✓
Environment Separation BTC’s infrastructure is segmented into distinct environments for development, production and QA operations, minimizing risk and limiting access between environments.
✓

AI Security

Control Status
AI Model Architecture Bluur® utilizes a frozen artificial intelligence model trained by BTC. Data classification is fully automated, operating with a classification accuracy of 95.3%. This architecture provides high-speed processing without user intervention.
✓
Data Privacy & Training The system does not learn on documents provided by customers. No customer data is collected, saved, or used for further training of the models, ensuring total data sovereignty.
✓
Data Isolation Each tenant’s knowledge base, logs, and configurations are stored in a dedicated database. This architecture ensures strict cross-tenant isolation and prevents any unauthorized data visibility.
✓
Model Updates Optimized versions of the model are released periodically through official system updates after rigorous internal testing by BTC.
✓
Risk Management Bluur® is designed to process documents based on predefined classification logic. Because the model is "frozen," its behavior is predictable and eliminates the risk of "model drift" or unauthorized autonomous learning.
✓
Audit & Transparency All automated classification actions are recorded within the anonymization history, providing full traceability of which documents are classified with AI.
✓

Privacy

Control Status
GDPR BTC is committed to protecting the privacy of its customers and, where applicable, complies with the EU General Data Protection Regulation (GDPR).
