MPC-based key orchestration secures static data, ensuring keys are never available as a single static asset.
Neutralize unauthorized database access by eliminating the master key as a single point of failure.
MPCISO redefines security for static data by decoupling encryption keys from the database environment. By leveraging Multi-Party Computation (MPC), we distribute key management across independent, isolated nodes. This ensures that even if an adversary gains full administrative access to the database server, they cannot reconstruct the encryption keys required to access the data-at-rest.

Modern Zero Trust assumes that the service is the identity. It verifies that Service A is authorized to communicate with Service B, which is highly effective against external attackers.
The gap appears when we ask who operates the service. In classic Zero Trust architectures, the admin or infrastructure running the service can naturally access the keys. That means the system still trusts the operator, creating meaningful risk from malicious or accidental exposure.
| Attribute | Zero Trust (Service Identity) | MPC (Distributed Trust) |
|---|---|---|
| Authentication Unit | The service identity | The computation party |
| Key Location | Centralized in service or infrastructure memory | Split into shards across independent parties |
| Admin Risk | The operator can become all-powerful and extract keys | No single admin holds a complete key to extract |
| Resilience | Compromised if the service or server is breached | Requires cooperation, or compromise, of multiple parties |
The focus is the separation between the service that runs and the ability to decrypt. In healthcare systems, this is the difference between a platform that allows access and a platform that guarantees privacy through mathematics.
If the admin or platform running your service can see the keys, you do not have true Zero Trust. You have access protection. The next step is protecting the ability to decrypt.
MPCISO adds a transparent security proxy and distributed key layer that keeps full encryption keys out of the database, service runtime, and administrator's reach. Applications continue to operate normally, while decryption requires MPC-backed participation from independent nodes instead of trust in a single operator.
