The Infisical Gateway is a lightweight component that allows Infisical, a managed secrets services provider, to securely connect to private resources such as databases and internal APIs without exposing them to the public internet. It acts as an outbound-only bridge, enabling secure interaction between Infisical and private resources while keeping them fully protected from external access. The Gateway is deployed inside the private network using the Infisical CLI and uses a Relay Server managed by Infisical for authentication and communication with the Infisical Cloud. It implements end-to-end encryption using mTLS and QUIC protocols, ensuring secure data transfer between the Gateway and Infisical Cloud. The Gateway provides a simple and secure solution for connecting Infisical to private resources, reducing network complexity and operational overhead while meeting regulatory compliance requirements.
