The network is quiet. No outbound traffic. No inbound risk. Yet you need secure, controlled access to critical systems. This is where HashiCorp Boundary in an air-gapped environment changes the game.
What is HashiCorp Boundary in an Air-Gapped Environment
Boundary is a secure access management solution designed to grant dynamic, identity-based connections without exposing your network. In an air-gapped setting, Boundary operates without external dependencies, eliminating potential attack vectors from the public internet. This is not a compromise—it's a fully viable deployment model supported by HashiCorp for organizations with extreme security and compliance requirements.
Core Benefits of Air-Gapped Boundary
- Isolated Operation: No internet connectivity required. Boundary can be deployed inside a sealed network with all services self-contained.
- Granular Access Control: Automated, least-privilege access to hosts and services, enforced by policy.
- Centralized Secrets Management Integration: Works with Vault or other tools to deliver credentials only at session time, then revoke them instantly.
- Audit and Compliance: Complete audit logs stored locally to meet strict regulatory frameworks.
Deployment Considerations
Running HashiCorp Boundary in an air-gapped environment requires local hosting of all components—controllers, workers, Postgres database, and identity provider integrations. You will manage software updates manually, hosting artifacts in an internal repository. TLS certificates will be generated and renewed internally. Worker nodes communicate within the air-gapped network only, ensuring sensitive traffic never leaves the perimeter.
