SECURITY FROM THE
GROUND UP.
Loggio's security model is built around eliminating security risks rather than routing around them: no write path, no inbound connection, no stored files, no dependence on your network.
The device always initiates contact. Our cloud cannot dial in to the device or to your controller; there is no listener, no port, no VPN, no tunnel.
Your plant network carries nothing unless your IT team chooses to use plant/guest Wi-Fi for in-house firewall control and signal extension.
The cellular uplink is the device's own, encrypted end to end. Loggio handheld authentication is encrypted and keyed to the handset's own security hardware. Data lives on encrypted storage in US data centers, and processing happens entirely in the United States.
Your controller talks to one thing: the reader stage. The reader fills an isolated buffer, and all data required by Loggio is served from that buffer alone. A request from outside your plant terminates at the buffer boundary. It cannot reach through to the machine.
The write capability does not exist by design in the product. Even Loggio itself cannot enable a write-path because there is no write path. No risk of changed values, no risk of changed machine state, no risk of a user error messing something up. Your machine state is protected.
Your program and your logic leave every interaction exactly as they were found.
Machine data is processed and discarded, and your uploads are gone after intake: not archived, not recoverable, deleted. What persists is Loggio's own structured model of your machine, in our own proprietary format with zero raw PLC code, on encrypted US storage.
The commercial agreements we have in place with our cloud service providers require them to delete your data immediately after use, except for cases of automatic abuse flagging, which can trigger up to 30 days of retention for offline abuse detection. Your data is never used for training AI. A current list of our providers, with what each receives and their retention terms, is available on request at [email protected].
Loggio works from our proprietary data format derived from your upload, not from the controller. When you choose to connect the handheld for temporary troubleshooting, the device reads live values like the current step and module health. Loggio never accesses the program itself inside your PLC so the logic in your machine stays in your machine.
