Pixel & GrapheneOS
Why Pixel and GrapheneOS — and nothing else.
Managing one stack isn’t a limitation; it’s the strategy. GrapheneOS on Google Pixel is, by a wide margin, the most defensible mainstream mobile platform available — and committing to it is what lets GemiGuard MDM offer controls a general-purpose MDM never could.
A foundation built on hardware, not promises
GrapheneOS is a hardened, deGoogled Android. It ships with no Google apps, services or account — and it never will — while hardening the OS itself with an advanced memory allocator, exploit mitigations and per-app sandboxing that go well beyond AOSP. Crucially, it runs only on Pixel hardware, because Pixels are the phones that actually provide the security primitives the OS depends on.
What the hardware gives you
Secure element
The Titan M2 secure element provides a hardware keystore with brute-force throttling, so device keys are protected even against a determined physical attacker.
Verified boot
Hardware-backed verified boot with rollback protection ensures the device only runs the exact, untampered OS image you expect — and can prove it.
Memory tagging
Newer Pixels add hardware memory tagging (ARM MTE), neutralising a large class of memory-corruption exploits at the silicon level.
7-year update window
Pixel hardware carries the longest guaranteed firmware and OS update commitment in the industry — so a managed fleet stays patched for years.
The decisive differentiator
Hardware attestation: prove a phone is what it claims to be
Stock-Android MDMs lean on Google’s Play Integrity to judge whether a device is trustworthy. With no Google in the stack, GrapheneOS does something stronger and more honest: hardware-backed remote attestation. Each device cryptographically proves, using the secure element, that it is running genuine GrapheneOS with the correct verified-boot key and OS version — no tampering, no rollback, no impostor. GemiGuard MDM runs these checks continuously and alerts you if a device ever falls out of attestation. It is the single capability the entire deGoogled-competitor field structurally cannot replicate.
Supported devices
We manage Pixel models currently supported by GrapheneOS and inside their guaranteed update window:
- Pixel 10 / 10 Pro / 10 Pro XL / 10 Pro Fold

New to the platform? We can advise on hardware selection and supply pre-configured, enrolled Pixel devices as part of a managed rollout. For the authoritative, current list, see the GrapheneOS FAQ.
An honest word on what this means
Choosing GrapheneOS is a deliberate trade. You give up Google’s convenience layer — Managed Google Play, Zero-Touch, Play Integrity — and in return you get a device the vendor cannot quietly reach into, an OS you can audit, and integrity you can prove in hardware. For organisations whose threat model includes the platform vendor itself, that trade isn’t close. GemiGuard MDM exists to make managing that platform as straightforward as managing any other fleet.
