Guard your devices from untrusted mobile networks with AltoGuard Relay.
Mobile devices are central to our working lives – always on, always connected, always within reach. With threats increasingly targeting the pathways that keep our devices talking to the world, it’s crucial to protect the channels we depend on every day, even those that most of us never see.
PentenAmio’s AltoGuard Relay ensures that your most sensitive devices remain secure, no matter the network. Relay handles the hazardous job of talking to the network, keeping your device – and everything on it – physically isolated from the threat.
Functionality
How AltoGuard Relay works

VPNs, security software, encrypted messaging apps – they all run on your phone’s Operating System (OS). Beneath the OS lies the Baseband Processor; a completely separate chip designed to connect you to the mobile network.
Baseband attacks could mean everything from your SMS being read, to your location being known, to a compromise of all the data on your device. In hostile environments where the mobile network cannot be trusted, you need a physical barrier.
Specifically designed to mitigate this threat, AltoGuard Relay sanitises the connection between your phone and untrusted mobile networks.
Your device stays connected. Your data stays yours.
