# Overview

This section covers the three common connection models:

- [IP Allowlisting](/en/docs/integrations/connections-cloud-on-prem/ip-allowlisting)
- [Enterprise Connection Network](/en/docs/integrations/connections-cloud-on-prem/enterprise-connection-network)
- [VPN](/en/docs/integrations/connections-cloud-on-prem/vpn)

Choose the model based on security requirements, network constraints, and operational effort.
