How is client data isolated within Brandlight infra?

Core explainer

What is Brandlight's approach to data isolation?

Brandlight isolates client data through layered physical, network, and operational boundaries, augmented by cloud isolation via a virtual air gap that uses temporary, tightly controlled connections for backups. This approach creates distinct domains for each tenant and enforces separation at multiple layers to limit any cross-tenant access or leakage.

The architecture also emphasizes data locality and tenancy discipline, ensuring data resides in defined regions with replicas moved only under policy, preserving air-gapped copies even as operational needs require accessibility. Immutability is reinforced with WORM-like snapshots and time-bound locks, while governance relies on quorum for critical changes and RBAC/ABAC-based access controls reinforced by MFA, all supported by audit-ready logs to ensure traceability and compliance. Together, these controls reduce the attack surface, support rapid recovery, and help meet regulatory requirements without compromising agility.

For practical context on governance and data resilience, Brandlight data governance resources offer a real-world blueprint for implementing these controls across complex environments, illustrating how brandlight.ai positions data isolation as a foundational resilience capability.

How are encryption and key management implemented?

Brandlight protects data through encryption in transit and at rest, coupled with centralized key management to ensure consistent, controlled access to cryptographic material. This combination helps ensure data remains unreadable even if storage or network boundaries are breached.

In transit, Brandlight uses modern TLS protocols (TLS 1.2+), while at rest, it relies on strong encryption standards such as AES-256. Keys are managed via a centralized service (for example, AWS KMS in the reference architecture), with strict policies that disallow access to unencrypted data and enforce separation of duties. Regular auditing and comprehensive logging accompany these controls to support governance, incident response, and compliance monitoring, helping to ensure that encryption remains effective across all environments.

How is data locality and tenancy enforced?

Data locality and tenancy are enforced through region-based residency and org ID-based isolation, ensuring that data remains within approved jurisdictions and clearly separated by tenant context. This approach supports regulatory requirements and reduces the risk of cross-tenant data exposure in shared environments.

Data resides in defined regional boundaries (for example, United States—Oregon; Germany; Singapore; Australia) with tenancy boundaries that prevent cross-tenant access. Cross-region replication is governed by policy to preserve air-gapped copies and avoid inadvertent exposure, while data segregation remains explicit at the tenancy level to minimize lateral movement. This design supports governance, auditability, and resilience, enabling predictable recovery and compliance across multi-cloud and hybrid environments.

Across these controls, Brandlight emphasizes a clear separation of data per tenant, with autonomous handling of backups and replicas so that operations on the primary environment do not compromise isolated copies or violate regional constraints.

What immutability and governance controls exist?

Brandlight provides robust immutability and governance controls designed to withstand ransomware and insider threats, including WORM-style snapshots, time-bound locks, and governance mechanisms like Quorum. These capabilities ensure that critical restore points and backup copies remain immutable for defined periods and require multiple approvals to alter configurations or data objects.

Immutable copies are maintained as read-only snapshots that cannot be deleted or changed until user-defined expiration, and policy-based data isolation can move immutable replicas to other sites, clusters, or cloud locations without compromising the air-gapped copies on the target. Quorum requires two or more people to authorize changes to configurations or access, reinforcing governance and reducing the risk of unilateral administrator actions. RBAC/ABAC together with MFA enforce least-privilege access, while comprehensive audit logs provide end-to-end visibility for forensics and compliance reporting.
