Operationalizing Digital Sovereignty for a Multi-Region Cybersecurity Platform on AWS
Key Challenges
Unosecur faced critical limitations in its on-premises setup, including the inability to enforce data residency, lack of region-specific controls, and insufficient isolation between environments. This created risks of unauthorized data movement, compliance violations during failover, and exposure to security threats. Additionally, fragmented monitoring and limited scalability impacted operational efficiency and platform performance.
Key Results
The AWS-based architecture enabled strict enforcement of data residency across regions, eliminating unauthorized cross-border data flow. Disaster recovery was significantly improved with ~30-minute RTO and near-zero RPO, while maintaining compliance. Enhanced security monitoring and isolation strengthened threat detection and access control, and the platform now supports scalable, high-availability operations with reduced operational overhead.
Overview
Unosecur is a cybersecurity SaaS provider delivering threat intelligence and analytics for enterprise customers across Europe and India. The platform processes sensitive datasets, including security logs, operational telemetry, and customer-specific threat data, requiring strict adherence to data residency, access control, and auditability requirements.
To support expansion into regulated markets, Unosecur required a production-grade architecture that enforces Digital Sovereignty as verifiable, technical controls embedded within the system design.
Challenges
Unosecur’s on-premises MongoDB-based deployment lacked enforceable jurisdictional controls. Data residency could not be guaranteed, and there were no mechanisms to prevent cross-region data movement during normal operations or failure scenarios.
Environment isolation between development, production, and management was insufficient, increasing the risk of unauthorized access. Disaster recovery processes were not aligned with regulatory expectations, creating potential compliance violations during failover. Security monitoring was fragmented and reactive, while infrastructure scalability limitations affected performance and operational efficiency.
Solution
The AWS Partner implemented a multi-account, multi-region architecture that enforces Digital Sovereignty across network, data, and control layers.
As outlined in the deployed architecture , the platform is structured across a Master account (control plane) and isolated Development and Production accounts (data plane). Control-plane services—such as Route 53, Jenkins, and Vault—are intentionally restricted from direct access to customer data.
Production workloads are regionally deployed in Frankfurt (EU) and Mumbai (India). Amazon Route 53 enforces data residency at the ingress layer, routing users to region-specific endpoints and ensuring data is processed within its jurisdiction from the point of entry.
Application workloads run on Amazon EC2, with MongoDB deployed independently per region. Amazon S3 provides region-specific object storage, and any cross-region replication is encrypted, asynchronous, and restricted to disaster recovery scenarios.
Identity and access are governed through IAM policies and HashiCorp Vault, enforcing least privilege. Administrative access is secured via VPN-based controls.
Digital Sovereignty Controls and Enforcement
Digital Sovereignty is enforced through layered, implementation-level controls:
- Data Residency Enforcement:
Geographic routing ensures data enters and remains within the correct region. No global endpoints are exposed. - Environment and Account Isolation:
Separate AWS accounts and VPC isolation prevent lateral movement and enforce strict boundaries. - Sovereign Data Storage:
Region-specific MongoDB deployments and S3 buckets ensure localized data storage. Replication is controlled and limited to DR. - Sovereign Disaster Recovery:
AMIs are replicated to a DR region, but failover requires explicit orchestration via Jenkins and Route 53. Recovery actions are auditable and compliant, achieving ~30-minute RTO and near-zero RPO. - Localized Security Monitoring:
GuardDuty operates per region, while Security Hub aggregates findings without transferring sensitive data. Logs remain regionally stored. - Auditability and Observability:
CloudTrail and CloudWatch provide full traceability, with integration into ITSM systems for incident tracking and response.
Validation and Operational Assurance
The solution was validated through controlled failure scenarios, including EC2 termination, database failover, and network partition testing, ensuring both resilience and compliance.
Automated disaster recovery drills are executed periodically via Jenkins, confirming that recovery workflows remain reliable and aligned with sovereignty requirements.
Business Outcome
The implementation achieved full enforcement of data residency across EU and India, eliminating unauthorized cross-border data movement. Disaster recovery capabilities improved significantly, reducing recovery time to approximately 30 minutes while maintaining compliance integrity.
Security visibility was enhanced through continuous monitoring, enabling faster threat detection and response. The platform now supports scalable, high-availability operations with reduced manual overhead.
Business Impact
Unosecur successfully expanded into regulated markets while maintaining compliance and customer trust. The architecture reduced operational risk, improved resilience, and enabled scalable growth.
Digital Sovereignty transitioned from a policy requirement to an enforced architectural capability, providing a measurable competitive advantage.
Conclusion
This case study demonstrates a production-grade implementation of Digital Sovereignty on AWS, where compliance is achieved through enforceable technical design. By combining regional routing, multi-account isolation, controlled disaster recovery, and localized monitoring, Unosecur established a secure, compliant, and scalable platform for global enterprise customers.
