Secure agent access to internal resources
Autonomous agents now query databases, call internal APIs, and update your CRM, reaching private systems never meant to be public. Instead of broad credentials or open firewall ports, NetBird gives each agent its own network identity and lets it reach only what policy allows.
One network for every internal resource
Agents connect over encrypted tunnels to the exact systems they need, and nothing else on the network is reachable.
Databases
Postgres, MySQL, Mongo, and managed cloud databases, reachable without public exposure.
Internal web servers & APIs
Private HTTP APIs, internal dashboards, and backend services.
CRMs & business apps
Self-hosted or private-network CRMs, ERPs, and line-of-business tools.
Staging & infrastructure
Staging environments, message queues, caches, and admin tooling.
How it works
Give the agent its own identity
Run the NetBird client alongside your agent, as a sidecar or on the same host. It joins your network as its own peer with its own identity, not a shared service account that everything reuses.
Scope it with policy
Put the agent in a group and write a policy: this agent reaches only the database and the CRM API. Anything outside that policy is denied by default.
Connect over encrypted tunnels
The agent reaches each resource through direct peer-to-peer WireGuard tunnels. Internal systems stay private with no public ingress, and traffic is encrypted end to end across cloud, on-prem, and hybrid.
Audit and revoke instantly
Every connection is logged with the agent's identity. Tighten a policy or pull the agent from its group and its access drops within seconds, containing a misbehaving or compromised agent on the spot.
Give your agents access to internal systems without opening a single port.

How do AI agents access internal databases and APIs securely?
Each agent runs a NetBird client and joins your network as its own peer. A policy scopes it to exactly the resources it needs, for example one database and one CRM API, and it reaches them over direct, encrypted peer-to-peer WireGuard tunnels. Nothing else on the network is routable to it.
Do I need to expose internal systems to the internet?
No. Internal databases, APIs, and apps stay entirely off the public network. Agents reach them through private tunnels rather than open ports or forwarded firewalls, so there is no public ingress to attack.
How does NetBird give each agent its own identity?
Instead of sharing a service account, each agent joins the network as its own peer with its own identity. Every connection is logged under that identity, so access records name the specific agent for real attribution and forensics.
How do I contain a compromised or misbehaving agent?
Remove the agent from its group or tighten its policy, and its access to every resource drops within seconds. There are no standing credentials to hunt down, so containment is immediate.
Does this work across cloud, on-premises, and hybrid environments?
Yes. NetBird forms one identity-aware overlay across cloud, on-prem, and hybrid, so agents connect to the resources they're authorized for regardless of where those systems run.
