Connector & Data-Boundary Security: Least-Privilege, Injection-Aware, Residency-Correct Agents Inside Your Tenant
A connector risk and data-boundary program — not a one-time review — so agents can act inside M365, Salesforce, and email without amplifying oversharing or leaking data.
What this solution does
A connector and data-boundary program builds a connector registry (scopes, subprocessors, residency, logging, training), enforces minimum-required scopes, inserts a policy layer between user intent and connector calls, tags every retrieved document as potentially injection-bearing, cleans up SharePoint / OneDrive oversharing, and stands up synthetic prompt-injection and exfiltration tests in staging. It replaces one-off reviews with a continuous program.
The buyer problem
- ›AI connectors amplify pre-existing SharePoint / OneDrive oversharing overnight
- ›OAuth scopes granted broadly at rollout, never trimmed back
- ›No effective-access audit — 'assumed access' ≠ 'effective access'
- ›Prompt injection via user-supplied content (email, tickets, docs) is a live threat
- ›Silent vendor changes (flex routing, subprocessors) breaking residency posture
Good-fit signals
- M365 / SharePoint / OneDrive-heavy midmarket (healthcare, finance, professional services, education)
- Regulated or cross-border data with residency obligations
- Considering Claude, ChatGPT Enterprise, Copilot, or custom agents against tenant data
- Head of IT or security-minded tenant admin already flagging risk
Pilot scope
In scope
- +Effective-access audit across the tenant (users, groups, sharing links, guest access)
- +Connector registry: scopes, subprocessors, residency, logging, training behavior
- +Scope-minimization pass on every sanctioned AI connector
- +Provenance tagging + injection sanitization between retrieval and model
- +Synthetic prompt-injection and exfiltration test suite in staging
- +Residency-change monitoring for Microsoft / Google / SaaS tenant defaults
Out of pilot scope
- −Full DLP program rebuild
- −Endpoint EDR deployment
- −Third-party pen-test replacement
Timeline: 8–14 weeks · Investment: Fixed-fee per platform or connector family
Systems we typically integrate
- Microsoft 365 (SharePoint, OneDrive, Teams, Exchange)
- Google Workspace (Drive, Gmail, Groups)
- Salesforce / HubSpot
- MCP servers + third-party connectors
- Entra ID / Okta for scope management
- SIEM (Sentinel, Splunk, Elastic)
Where humans stay in the loop
- New connector approvals require a named data-boundary owner
- Scope increases require re-review with residency check
- External-send actions from any connected agent always gated
- Injection-detection anomalies escalate before the run completes
KPI scorecard
| Metric | Typical baseline | Pilot target |
|---|---|---|
| Average OAuth scope reduction per connector | Broad grants | 40–70% reduction |
| Connectors with verified residency map | Ad hoc | 100% |
| Oversharing findings remediated | Unknown | Trending to zero backlog |
| Prompt-injection ASR in test harness | Untested | Baseline set + trending down |
Risks and the controls we put in place
Silent vendor-side residency changes
Weekly monitoring of provider status pages + configuration diffs; named owner alerted on change.
Overconfidence in 'read-only' connectors
Read is still exfiltration surface — every retrieval scored for sensitivity + logged with provenance.
Exceptions granted under business pressure
Time-boxed exception register with automatic expiry + audit review.
Multimodal / visual prompt injection
Image and document content sanitized + provenance-tagged before reaching model; visual-injection tests included in suite.
How we help
Effective-access first
We audit real access, not org-chart access, before touching a single connector setting.
AgentDojo-style test harness
We deliver a reusable injection + exfiltration test suite you can run against every future agent.
Residency-aware architecture
Where flex routing or subprocessor drift is a risk, we design around it — not after an audit finding.
Continuous, not one-shot
The registry, tests, and monitoring keep running after we leave; no report-in-a-drawer engagements.
Frequently asked questions
Isn't this just a SharePoint permission clean-up?+
Permission hygiene is one step. The program also covers OAuth scopes, subprocessor drift, residency, injection defense, and continuous testing.
How is prompt injection actually tested?+
We adapt public benchmarks (AgentDojo-style) to your tools + connectors and run adversarial tasks against staging with pass/fail thresholds you own.
Can we do this before rolling out a new connector like Claude for M365?+
That is the ideal sequencing — the review answers 'would you allow this in our tenant?' before enablement, not after.
Does this replace our DLP program?+
No. It integrates with DLP but focuses specifically on the AI-connector surface, which most DLP programs don't yet cover well.
How often should the review re-run?+
Registry + monitoring is continuous; deep effective-access audit is quarterly for high-risk tenants and semi-annually otherwise.

MCP vs Custom Integration: When to Use Each in 2026
MCP for reusable, well-maintained tool surfaces. Custom for fine-grained auth, latency-critical paths, or one-offs. Most production stacks run both — here is the dividing line.
