CONTINUOUS PROTECTION
Secure by design at every layer
From network perimeter to AI inference -- everything runs inside Stell’s AWS GovCloud authorization boundary. No data leaves. No corners cut.
Access Control
Role-based, granular permissions enforce least privilege and access to secure information.
Encryption
Advanced FIPS 140-2 validated encryption protects data in transit and at rest, with HSM for cryptographic key management.
Testing
Continuous vulnerability scanning, automated security testing, and annual penetration tests assess ongoing resilience.
Governance
Background-checked team members follow NIST 800-53/171-aligned incident response and change-control processes.
AI Boundary
All AI runs entirely on AWS GovCloud. No external model calls - prompts and embeddings never leave the authorization boundary.
Infrastructure
100% AWS GovCloud (US). All customer data processed and stored within U.S. jurisdiction on dedicated infrastructure.
