Eliminate the attack surface, not just defend it.
The OS has always been the endpoint's largest attack surface and least trustworthy component, it persists, drifts, and accumulates credentials. Every dollar of endpoint defense goes to watching and patching that surface. The ZeroTrustOS re-architects the layer so the surface isn't there.
You can't be breached through state you don't keep.
Persistence is the substrate every endpoint attack runs on, malware needs somewhere to install, credential theft needs something cached, lateral movement needs a foothold to pivot from, and post-breach recovery exists only because the machine remembers. Hardening constrains that state; it doesn't remove it. Scylos removes it: the device boots from a verified baseline, runs only authorized work, and resets to known-good every session.
What the endpoint stops doing
Boots from a verified baseline
Every session starts known-good, no drift, no accumulated image to attest or trust.
Runs only authorized work
Execution scope is declared centrally; nothing else can establish on the device.
Retains nothing
No local data, credentials, tokens, or config survive the session. Nothing to exfiltrate at rest.
Resets to known-good
Compromise recovery is a reboot, not a reimage or an incident-response engagement.
Defend the surface vs. remove it
How it fits your program
Does this replace our identity and network controls?+
No. Scylos removes the endpoint as an attack surface; identity, MFA, email security, and network controls stay. It makes Zero Trust a property of the device rather than a policy layered onto a persistent machine.
How do we get telemetry without an agent?+
Signals come from the cloud control plane and the session itself rather than a kernel agent on a persistent OS, so there's no agent to corrupt, bypass, or push a bad update into.
What about compliance and audit?+
With no data at rest on the endpoint, the device-level scope of most frameworks shrinks dramatically. Your obligations remain, but there's far less surface to attest, encrypt, and prove.
