The Fly.io platform comes with built-in security like hardware isolation, [private networking](/networking/private-networking) over WireGuard, and [TLS termination](/networking/services#tls-handler). *** Illustration by Annie Ruygt of a phoenix jumping with a motor bike ## Organization and app security *Security for customer organizations and apps.* * **[Organization Roles and Permissions](/security/org-roles-permissions):** Understand what Members and Admins can do in a Fly.io organization, and how to manage access safely. * **[Use SSO for organizations](/security/sso):** Set up org-wide Single Sign-on with Google or GitHub. * **[Remove a member from an organization](/security/remove-org-member):** Remove a user from an organization and take steps to help keep the organization secure. * **[Built-in TLS termination](/security/tls-termination):** You get TLS termination by default for your web apps. #### Security extensions *Security add-ons from our extension partners.* * **[Application Security by Arcjet](/security/arcjet):** Use the Arcjet security layer to protect your JavaScript app with just a few lines of code. #### Tokens *Control access to your Fly.io organizations, apps, and Machines with tokens.* * **[Access tokens](/security/tokens):** Use tokens to manage access to organizations and apps. * **[OpenID Connect](/security/openid-connect):** Use OpenID Connect (OIDC) to manage access to 3rd party services. *** ## Fly.io platform security *Fly.io corporate security, compliance, and shared responsibility.* * **[Shared responsibility model](/security/shared-responsibility):** An overview of the separation of responsibilities for security on Fly.io. * **[Fly.io security practices and compliance overview](/security/security-at-fly-io):** Learn about our security practices for the Fly.io platform. *** ## Talk to the security team If you have a security question, concern, or believe you’ve found a vulnerability in any part of our infrastructure, please contact us.
