Credential and secret protection

Data boundaries

Control what information can be provided to models, retrieved from company systems or returned to users.

Agent permissions and tools

Restrict AI agents to the functions, data and actions needed for their approved purpose.

Human approval controls

Require appropriate review before sensitive, financial, destructive or externally visible actions are completed.

Record important prompts, responses, tool calls, approvals, exceptions and administrative changes.

Guardrails and validation

Apply input validation, output checks, allowlists, business rules and other controls around model behaviour.

Incident response and shutdown procedures

Define how to disable the application or agent, revoke credentials and investigate unexpected activity.

Secure development and change management

Integrate security review, testing and approval into development and deployment processes.

How we deliver it

We review the intended use case, architecture and integrations with your developers and system owners. We identify the most important attack paths and failure scenarios, then design controls around the way the application actually works.

Apexagen can provide the recommendations, work with your development team or help implement the agreed controls.
