Integrate
What you plug in. What changes. What you rewrite.
The decryption gap is the moment data must be decrypted to be used. Umbra is a host-attached PCIe card for institutional and government buyers. It drops into a standard server: that is the commercial wedge.
What the card is, physically
| Form factor | Full-height, full-length, single-slot |
|---|---|
| Interface | PCIe ×8 Gen3 |
| Power | 25–75 W |
| Cooling | Passive: requires directed chassis airflow |
| Attachment | Host-attached: no on-card network interface |
| OS | Ubuntu 22.04 LTS · RHEL 8 / 9 |
| Throughput | 40M ops/s measured |

What runs on it
| Surface | What it is | Who uses it |
|---|---|---|
| RainDB | Encrypted SQL. Queries run on ciphertext; results return encrypted; the engine never sees a plaintext row. | Data platform teams |
| ZChat | Encrypted LLM inference. Prompts, context, and outputs stay encrypted through execution. | AI/ML teams |
| SDK | Programmatic access to encrypted operations. Same surface on card and node. | Platform engineers |
Anything built on a card runs unchanged on a node, and carries forward across Umbra silicon generations.
