Deployment and Integration

This section describes how BeaconGuard Assurance is deployed and integrated into existing systems. The guidance is intentionally conservative and environment- agnostic to support regulated environments.

BeaconGuard is designed to deploy alongside existing applications without changes to model internals and without distributing governance rules throughout application business logic. Applications submit signed request metadata, workflow identity, user role, source-system trust, approved-pathway status, deterministic context tags, request IDs, timestamps, freshness windows, and policy inputs, then enforce BeaconGuard’s explicit decision response.

Deployment Model

BeaconGuard is deployed as an independent inline policy proxy or policy enforcement point at the AI request boundary.

Common deployment characteristics:

• Runs as a standalone process or container
• Stateless execution model
• Horizontal scalability
• Externalized configuration and secrets

The deployment environment is responsible for:

• Process isolation
• Network controls
• Transport security (e.g., TLS)
• Secrets management

Integration Pattern

BeaconGuard integrates at the AI request authorization boundary.

Typical request flow:

1. Existing application prepares an AI-bound authorization request
2. Request metadata and workflow context are normalized and sent to BeaconGuard
3. BeaconGuard evaluates against the active policy snapshot
4. A deterministic allow, deny, or needs-review decision is returned
5. Application enforces the decision before model execution

BeaconGuard does not:

• Call back into applications
• Maintain session state
• Mutate application data
• Replace workflow logic, systems of record, SIEM, IAM, GRC, EHR, AML, fraud, or case-management systems

Request Inputs

Integration requires explicit request inputs, including:

• Actor identity (user, system, service)
• Signed request metadata
• Workflow identity
• Source-system trust
• Approved-pathway status
• Deterministic context tags
• Request IDs, timestamps, and freshness windows
• Requested action or capability
• Contextual attributes required by policy
• Reference artifact identifiers (if applicable)

Inputs must be complete and explicit. Missing or malformed inputs result in a fail-closed decision.

Policy Distribution

Policy snapshots are distributed to enforcement runtimes out-of-band.

Distribution properties:

• Snapshots are signed before distribution
• Enforcement verifies signatures before use
• Snapshot identity is fixed for evaluation
• Rollout and rollback are explicit

Hot-reloading of policy is allowed only if snapshot identity is preserved.

Audit Integration

Applications are not required to manage audit storage.

BeaconGuard:

• Emits structured audit records per evaluation
• Includes policy identity and decision metadata
• Can integrate with external storage or pipelines

The audit sink must be append-only and durable to preserve evidentiary value.

Failure Handling

Applications must be prepared to handle denial and needs-review outcomes.

Failure cases include:

• Missing policy snapshots
• Verification failures
• Input normalization errors
• Internal evaluation faults

In all blocking cases, BeaconGuard returns a deterministic DENY or NEEDS_REVIEW outcome based on governed policy.

Environment Separation

Recommended environments include:

• Development (non-production data)
• Testing / validation
• Production

Policy snapshots and signing keys must not be shared across environments.
