Integration Security

Executive Summary

Integration Security defines security controls for Algosure external integrations. All integrations require tenant context, authorization, consent, audit, encryption, secret management, validation, retry, error handling, idempotency, and rate limiting.

Why This Exists

Integrations connect Algosure to external authorities and providers. They can expose sensitive customer data, credentials, documents, payment flows, compliance records, and AI context if not controlled.

Owner

The owner is the Chief Product Officer and Enterprise Architect.

Business Value

Secure integrations protect customer trust, reduce breach risk, support regulatory posture, and make provider failures recoverable.

Security Rules

Rule	Requirement
Tenant context required	Every integration action must be tenant-scoped.
Authorization required	Users, services, and AIOS must be authorized before integration actions.
Consent required	External access to mail, storage, messaging, signatures, government records, or partner data requires approved consent where applicable.
Secrets protected	Provider credentials, tokens, webhook secrets, and service credentials stay in approved secrets management.
Validate inbound data	Provider callbacks and responses are treated as untrusted until validated.
Encrypt in transit	External communication requires encrypted transport.
Audit everything material	Requests, responses, failures, retries, credential use, accepted facts, and callbacks are audited.
Rate limit and back off	Provider and Algosure rate limits must be enforced.
Idempotency required	Retries and callbacks must not duplicate effects.
Fail closed	Ambiguous authorization, missing tenant context, invalid signature, or unknown provider state must not produce accepted facts.

Error and Retry Rules

Situation	Architecture Response
Transient provider failure	Retry according to bounded policy.
Provider rate limit	Back off, preserve state, and surface operational visibility.
Invalid provider response	Reject, audit, and require review or retry if safe.
Authorization or consent failure	Stop processing and audit denial.
Duplicate callback	Process idempotently.
Unknown state	Preserve evidence and escalate to owning Domain workflow.

Non-Implementation Boundary

This document does not define credential formats, token storage, signature algorithms, exact retry intervals, rate-limit values, or provider-specific security settings.
