NextZen Security · Secure AI engineering
Build, contain and deploy enterprise AI safely.
NextZen Security pairs forward deployed engineering teams with a containment engine for AI deployments: code-level permission boundaries and secure agentic workflows, implemented directly inside your repositories. The engine is being productized from controls proven in client engagements.
Thirty minutes, no obligation. Written scope and fixed-fee proposal within one business day of your call.
What we do first
We make AI deployments safe to ship — in your repositories, not in a report.
Forward Deployed AI Engineering
Engineers embed in your team and repos to build permission boundaries, guardrails and deployment controls. You receive reviewed code, evaluation tests and a documented handover.
View service 02AI Application Security & Red Teaming
We test whether your AI application can leak data or act beyond its permissions, with reproducible findings and an agreed retest.
View service 03AI Threat Modeling
Map how your AI system can be abused before someone else does, and agree the controls that close the paths that matter.
View serviceHow the controls fit
Every request passes a permission check before it reaches your data or tools.
We build the boundaries into the deployment itself: identity at the application, approval gates in the orchestration layer, restricted permissions on tools, and evaluation tests that run before each release.

When clients call
Your AI prototype works. Is it ready for production?
From prototype to production
Your prototype is ready, but your team needs help implementing deployment safeguards.
Agents with production access
An agent needs production access, but its permissions have not been reviewed.
Evidence for enterprise buyers
An enterprise customer needs evidence of your AI controls before approving the purchase.
