Staging environments for WordPress sites on Google Cloud Platform (GCP) can be easily created using Twingate Starter, a new free plan designed for home and personal use. With Twingate, users can set up a private staging environment that is completely inaccessible from the public internet but still shareable with collaborators or clients. The process takes under 3 minutes to complete and involves deploying a Twingate Connector on GCP, adding a resource to the network, downloading the Twingate client, and sharing access with others. This solution provides a modern Zero Trust network that is more secure and maintainable than traditional VPNs.
