Private networking for agent systems

Identify which endpoints need to accept public traffic. Keep internal tools and data services behind deliberate access boundaries.

Give each connection a purpose, an owner and an authentication requirement. Private reachability alone does not establish permission.

List the external services required for the workflow. Decide how requests leave the environment and where failures or unexpected destinations become visible.

Keep credentials scoped to the service and action they support. Avoid a shared credential that turns one compromise into access to the whole workflow.

Keep development, testing and production boundaries explicit. Use controlled paths for the resources that must be shared.

Document the intended connections before choosing platform-specific networking features. The implementation should make that plan inspectable.

Test allowed traffic and traffic that should be denied. Include service-to-service access, outbound calls and operational access.

Keep useful connection logs and a recovery path. Recheck the policy when tools, destinations or responsibilities change.
