- We built the Chromium browser, its installer and its Omaha-based auto-updater, and tuned and hardened the build.
The client and the problem
Total Security Limited, a UK company, wanted a security browser of its own. A security browser has to install cleanly and patch itself without the user doing anything, so the update path mattered as much as any feature.
What we built
We built Total Security Browser on Chromium and gave it its own install and update path: a custom installer, and an auto-updater based on Omaha, the open-source framework Google uses to update Chrome on Windows. We also tuned the performance of the build and hardened it.
- A custom installer for the browser
- An auto-updater built on Omaha, so updates install without the user doing anything
- Performance tuning of the Chromium build
- Security hardening of the browser build
Why it was hard
Using Omaha for your own browser means running your own update server, signing every release and deciding how fast each new version reaches users. If any link in that chain breaks, users stop receiving security fixes, which is the one failure a security browser cannot afford.
