Overview

What Desktop Software Development covers

Desktop software must protect data at rest on the workstation and prove the integrity of every update it installs.

We build with signed release pipelines, OS credential stores and least-privilege installation defaults.

The problem we solve

Desktop applications often store secrets in plaintext configuration files and update over channels that are not integrity protected.
