Latest Patents

One of his latest innovations is the development of a system for establishing a Public Key Infrastructure (PKI) chain of trust in air-gapped cloud environments. This technology is designed to create a chain of trust for an unknown root certificate in an isolated network, verifying it using a trust chain external to the network. The process involves configuring a bootstrap executable and a leaf certificate rooted in the external chain of trust with an Object Identifier (OID). The system securely receives the leaf certificate in the isolated network, which is utilized to sign a new root certificate, resulting in a blob that is stored in a predetermined location. When the bootstrap executable is executed on a client machine, it retrieves the blob and verifies its signature using the leaf certificate. Successful checks ensure the new root certificate is distributed and installed in a PKI certificate chain of trust.

Another notable patent addresses compliance testing through sandbox environments. This innovation empowers compliance users or auditors to inject failures into a sandbox environment that mimics a live production service. It's monitored by the same automation that governs the compliance controls in production. By introducing compliance failures, users can validate that the monitoring system appropriately triggers alerts, fostering confidence in its effectiveness. The outcome of these tests is documented in a rich report, demonstrating how failures in compliance controls lead to expected monitoring alerts.
