Every organisation has devices it cannot see. The contractor's laptop. The developer's own MacBook. They reach company data, and none of them are enrolled in your MDM.
XFA verifies that every device used for work meets your security policy before sign-in — including the devices you do not own and cannot enrol. XFA connects to your identity provider, finds every device already accessing your platforms, and checks disk encryption, screen lock, antimalware, firewall, OS and browser versions, and more. Fail a check and the user gets a plain-language guide to fix it themselves. Keep failing and the device loses access.
No enrolment. No device takeover. XFA reads security posture, not files, browsing history or location, which is why freelancers and executives accept it where MDM gets refused. For auditors, it produces the device evidence behind ISO 27001, SOC 2 and NIS2.
