Datacenters have trusted hardware. Phones have secure enclaves. Robots — the machines that move through the physical world next to people — mostly have neither. PhyTAU gives every robot a hardware root of trust, so you can prove what it is, what it was running and what it did.
Every guarantee is checked by PhyCloud and recorded with the data, so it travels with the record into investigations, audits and evidence packages.
A verified identity
Each unit holds keys that are generated in hardware and never leave it. PhyCloud knows exactly which robot every record came from.
A verified software state
Only approved firmware runs, and every boot is measured and reported. You can prove what software a robot was running when something happened.
A record that cannot be quietly changed
Telemetry is signed on the robot before it goes anywhere. Edits, deletions, replays and gaps are all detectable in PhyCloud.
Proof it was there
Continuous heartbeats show the unit was present and running. Removing or bypassing it leaves a visible mark in the record.
Beyond telemetry
From trusted data to trusted autonomy
Robots are increasingly driven by AI agents that plan and act on their own. Before an agent is allowed to move a machine, someone has to be able to answer: is this the robot, the software and the model we approved?
Foundation
Trust the record
Every event is signed in hardware and traceable to a verified robot and software state.
Next
Trust the robot
PhyTAU attests the robot's main computer and its components, and flags anything that is not approved.
Enterprise
Trust the autonomy
Verified agents, models and policies, with every autonomous decision tied to the exact software that made it.
Offerings
Two tiers, one platform
Both tiers run the same PhyTrace agent and report to the same PhyCloud, so fleets can mix them and upgrade without re-integrating.
TPM 2.0 root of trust
PhyTAU
Hardware-anchored identity, measured boot and signed telemetry for AMRs, AGVs, drones and commercial fleets. Fits alongside the robots you already run.
Drop-in on ROS 2, CAN and serial
Signed, verifiable telemetry
Boot attestation for the unit and the robot computer
Enterprise-grade root of trust
PhyTAU Enterprise
A datacenter-grade root of trust for humanoids, defense, medical and critical-infrastructure robots, built to secure the whole robot — not just its data.
Attests every major component on the robot
Trusted identities for sensors and actuators
The foundation for trusted agentic autonomy
Integration
A trusted peer on the robot, not another wiring harness
PhyTAU joins the networks and buses the robot already uses. It does not need a connection to every sensor, and it does not need changes to your robot software.
