Overview

What Mobile Application Development covers

We build mobile applications assuming the device may be compromised: minimal local data, platform keystores, pinned transport and server-side enforcement of every rule.

The backing API is designed with the app, because that is where mobile risk concentrates.

The problem we solve

Mobile products frequently ship with sensitive data cached on device and business rules enforced only in the client.
