TL;DR: Open-weight models running inside private tenants and on-premises environments reduce data movement and improve deployment control for sensitive enterprise AI work, according to Redblock. The governance challenge shifts from model choice to identity, privilege, and operational boundary control, where execution inside the tenant still requires disciplined access enforcement.

Key questions
Q: How should teams govern open-weight AI running inside their tenant?
A: They should govern it as a privileged workload with a named owner, scoped permissions, and clear revocation paths.
Q: Why do local AI auth files create a high-value identity risk?
A: Because they often contain reusable credentials, especially refresh tokens, that outlive a single session and can be abused from another host.
Q: What breaks when AI agents have production access without containment?
A: What breaks is the assumption that identity permission alone is enough to control impact.
Practitioner guidance
- Define AI runtime identities Assign each model, agent, or orchestration layer a unique identity and owner so execution can be authorised and reviewed like any other privileged workload.
- Scope model permissions tightly Limit what the AI runtime can read, write, and trigger, especially where it can touch identity systems, remediation workflows, or production data.
- Separate inference from action Keep model generation distinct from remediation, provisioning, or administrative execution so a prompt or output cannot directly become privileged change.
Bottom line: Open-weight enterprise AI can reduce external data movement, but it does not remove the need to govern model invocation, privileges, and downstream execution.

Tenant-local AI shifts the control problem from data egress to identity governance. Keeping inference inside the tenant can reduce exposure to external processing, but it does not remove the need to govern who can invoke models and what those models can do next. The meaningful security boundary becomes the set of identities, permissions, and execution paths around the model runtime. Practitioners should treat the tenant boundary as a governance zone, not a guarantee of safety.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: How do identity teams decide whether customer-controlled AI is safer than external inference?
A: They should compare control over permissions, logging, dependency management, and revocation rather than assuming local hosting is automatically safer. Customer-controlled AI is preferable when the organisation can actually enforce access boundaries and operate the stack responsibly. If not, the internal deployment may simply substitute one dependency risk for another.
