Brain — cognition & secure cloud

Cognition is a hybrid stack. On-device, a 48 TOPS NPU runs the personality core, the real-time perception models and the safety governor — so the companion behaves correctly even when the network is gone.

For open-domain conversation, retrieval and continually-updated knowledge, the head connects over a hardware-rooted TLS 1.3 tunnel to Synara Private Cloud™ — a dedicated, single-tenant deployment of frontier large language models hosted inside a confidential-compute enclave (Intel TDX / AMD SEV-SNP). Model weights, conversation memory and user data never share infrastructure with any other tenant.

• Identity: per-unit cryptographic identity burned into a secure element at manufacture; cannot be cloned or transferred.
• Encryption: AES-256-GCM in transit and at rest; keys rotated every 24 h; perfect forward secrecy on every session.
• Boot: measured secure boot with TPM 2.0 attestation — the unit refuses to start if firmware has been altered.
• Memory: the user's private memory graph lives encrypted with a key derived from a passphrase only the user holds; even Synara engineers cannot read it.
• Network: isolated VLAN, mutual-TLS, no inbound listeners on the device — the companion calls out; nothing calls in.
• Standard: the deployment is built to meet FIPS 140-3 Level 3, ISO 27001 and the equivalent of the US DoD Impact Level 5 (IL5) regime for sensitive but unclassified data.

The result is a brain that can learn from the whole internet without the user ever becoming part of it.
