Valarian ACRA is a secure platform designed for data and compute control in high-security environments. The platform provides infrastructure for running compartmentalized and auditable applications, with deployment options inside a client's perimeter or through a managed security service provider. ACRA implements an isolated architecture where each environment operates independently without crossover between systems. The platform enforces compartmentalized access controls that restrict data and compute resources to their designated purposes, preventing lateral movement across the infrastructure. The system is designed for government and national security programs, as well as enterprise deployments. It supports the creation of new enclaves through a rapid provisioning process. The platform serves as the foundation for Valarian's suite of collaboration, compliance, and coordination tools. ACRA was developed by founders with backgrounds in military operations and classified data handling, as well as international finance security requirements. The platform addresses requirements for organizations that need strict control over data movement and trust enforcement at the infrastructure level.
