XFA is user-driven device security for fast-growing companies that want strong IT security without building an IT team. It checks every computer and phone at sign-in, whether company-owned, personal (BYOD) or a contractor's laptop, and guides people to fix issues themselves. XFA plugs into Google Workspace, Microsoft Entra ID, Okta, OneLogin, Ping Identity or Keycloak in about 15 minutes, with no devices to enroll and no MDM to roll out. People install the XFA app at their first sign-in, without admin rights. XFA verifies OS updates, disk encryption, screen lock, firewall, antimalware, browser version and more, and admins choose per policy whether to warn or block insecure devices. It discovers devices from sign-in logs, sends alerts by email, Slack or Teams, and exports audit evidence to Vanta, Drata, TrustCloud and Thoropass. XFA takes no control of the device and never collects files, messages or browsing history. Free plan available.
