Enterprise AI Agents

Compliance-ready AI agent execution with audit trails and NIST-aligned security.

Enterprise Requirements

Requirement	Challenge	Nucleus Solution
Audit trails	Prove what agent did and when	Cryptographic hash-chained logs
Data isolation	PII/PHI can’t leak to LLM providers	Execution in air-gapped VM
Least privilege	Agents shouldn’t have admin access	Capability-based permissions
Secret management	API keys must be rotated, protected	Keychain integration, 90-day rotation
Incident response	Forensic analysis after breach	Verifiable audit logs

Compliance Alignment

SOC 2

Control	Nucleus Feature
CC6.1 - Logical access	Lattice-guard permission boundaries
CC6.6 - System boundaries	Firecracker VM isolation
CC7.2 - Security events	nucleus-audit logging

HIPAA

Safeguard	Nucleus Feature
Access controls	Per-agent permission profiles
Audit controls	Cryptographic log verification
Integrity controls	Read-only rootfs, signed requests
Transmission security	HMAC-SHA256 request signing

NIST SP 800-57 (Key Management)

Requirement	Implementation
Key generation	32-byte cryptographically random secrets
Key storage	macOS Keychain (hardware-backed on Apple Silicon)
Key rotation	90-day tracking with warnings
Key destruction	Secure deletion via Keychain API
