Prior to working full time on OpenSecurityTraining2 (ost2.fyi), Xeno worked at Apple designing architectural support for firmware security; and code auditing firmware security implementations. A lot of what he did revolved around adding secure boot support to the main and peripheral processors (e.g. the Broadcom Bluetooth chip.) He led the efforts to bring secure boot to Macs, first with T2-based Macs, and then with the massive architectural change of Apple Silicon Macs. Once the M1 Macs shipped, he left Apple to pursue the project he felt would be most impactful: creating free deep-technical online training material and growing the newly created OpenSecurityTraining 501(c)(3) nonprofit.
