Hardened substrate. We assume the hardware is hostile and verify it. From supply chain BoM validation to runtime DMA protection.
Preventing hardware-based attacks.
DMA Remapping. Strict IOMMU grouping ensures that rogue peripherals (like Thunderbolt devices) cannot read kernel memory via DMA attacks.
SEV & TDX. Virtual machines are encrypted in memory with a key that the hypervisor does not possess, preventing host inspection.
UEFI Hardening. Automated analysis of option ROMs and system firmware to detect backdoors or unsigned code execution paths.
Peripheral Allowlisting. Policy-based USB authorization that creates a virtual firewall for physical ports, blocking unauthorized HIDs.
