Overview

The Integration Layer manages all external system connections — Salesforce, Slack, HubSpot, Jira, ServiceNow, and more. Each integration has isolated credentials, enforced OAuth scopes, and bidirectional data sanitization. Rate limiting prevents abuse of third-party APIs, and all data flowing through integrations is sanitized to prevent injection attacks and data leakage. The integration layer also manages session-scoped caching with encrypted cache data and automatic expiry.

Key capabilities

External Connectors

Pre-built connectors for Salesforce, Slack, HubSpot, Jira, ServiceNow, Teams, and custom webhooks.

Credential Isolation

Each integration has its own isolated credentials — compromising one connector does not expose others.

Data Sanitization

Bidirectional data sanitization prevents injection attacks and data leakage through integration points.

Rate Limiting

Per-integration rate limiting protects third-party API quotas and prevents abuse.

Encrypted Cache

Redis-backed session state with encrypted cache data, auto-expiry (24hr max TTL), never stores raw user data.

OAuth Scope Enforcement

Integrations are limited to the minimum required OAuth scopes — principle of least privilege.

Security implications

How Zone 5 enforces bRRAIn's zero-trust security model:

  • Credential isolation ensures a compromised integration cannot access other connectors
  • Bidirectional data sanitization prevents cross-system injection attacks
  • Rate limiting protects both bRRAIn and third-party services from abuse
  • Cache data is encrypted and auto-expires — maximum TTL of 24 hours
  • OAuth scopes are enforced per integration with least-privilege access
Every zone enforces its own security boundary. No zone trusts another implicitly.

How it connects

Zone 5 connects bRRAIn to external systems, passing data through sanitization before it reaches the MCP Gateway or returns to internal zones.
