Secure PostgreSQL Connections with Outbound-Only Pgcli
Pgcli with outbound-only connectivity solves the problem. It lets you connect to PostgreSQL without exposing inbound ports or weakening your firewall. No listener sits exposed, no open invitations on the perimeter. Every packet flows outward from your environment, through secure channels, into the database.
Outbound-only setups are common in zero-trust architectures. They improve security by removing the need for direct inbound access. Pgcli works with these designs using SSH tunnels, VPNs, or managed connectors. You can use a bastion host or container running Pgcli, configured to initiate all sessions outbound. This keeps the database hidden and unreachable from untrusted networks, yet still fully manageable by authorized operators.
To configure Pgcli for outbound-only connectivity:
- Run Pgcli on a host inside your secure network.
- Use
ssh -Lor an equivalent tunnel to route traffic to the PostgreSQL instance. - Set the connection string in Pgcli to point to the local tunnel port.
- Validate by ensuring no inbound firewall rules are opened.
Outbound-only modes also pair well with cloud database providers that support private endpoints. You can connect through internal routes, with Pgcli acting as the human-friendly interface for queries, schema inspection, and quick analysis. Advanced users often script Pgcli commands to automate checks or migrations, keeping everything within controlled outbound paths.
This design reduces the attack surface, meets compliance requirements, and preserves convenience for interactive querying. Pgcli remains fast and responsive, even when traffic is funneled through secure outbound routes.
A secure PostgreSQL connection should never depend on exposed ports. Try outbound-only connectivity with Pgcli, and see it live in minutes at hoop.dev.
