Browser extensions & automation
Many business tasks live in a browser. Our team builds browser extensions for specific jobs and automates web workflows with headless-browser tooling for testing, data entry and monitoring.
Our team builds Chrome extensions for specific tasks and automates web workflows with headless-browser tooling, for testing, data entry and monitoring. Small, focused tools often remove hours of repeated clicking without a large software project.
We build these tools with the same controls as larger systems: least-privilege permissions, logs, and a clear owner. When a workflow grows beyond what a script should handle, it moves into the Cyber Automation service, where agents work with guardrails and human approval.
What we do
- Chrome extensions on Manifest V3
- Playwright test suites for web applications
- Automated data entry between web systems
- Scheduled monitoring of web pages
- Screenshot and report capture
- Extension permissions review for security
- Retry and alert handling for failed runs
- Packaging and managed deployment of extensions
We keep automation narrow and observable, with logs and clear failure handling, so a changed web page produces an alert rather than silent bad data.
This group is part of Cyber Automation and Tailored Software. It is often the fastest way to connect a system that has no API.

How we use Browser extensions & automation for clients
Where this matters most
Frequently asked questions
Direct answers to the questions we hear most. Something else on your mind?
Send us a messageIs scraping allowed?
It depends on the site's terms and the data. We review that with you before building anything.
Who owns the code?
Terms are set in the engagement. Ask us for the current terms before you sign.
What is Manifest V3?
It is the current extension platform for Chrome and other Chromium browsers. It replaces long-running background pages with service workers and restricts remotely hosted code and some request-blocking features. New extensions must be built on it.
How do you keep an extension secure?
Request the narrowest permissions and host access, avoid injecting untrusted content into pages, keep all code inside the package, and review third-party libraries. We test what data the extension can read and where it sends it. Broad permissions are the main reason enterprise reviewers reject extensions.
What happens when a website changes and the automation breaks?
A well-built automation detects the failure, stops and alerts someone, instead of continuing to enter wrong data. We use stable selectors, wait for page states and keep screenshots and logs of each run. Where the site offers an API, we use that, since it is less fragile than browser steps.
How can extensions be deployed to company computers?
Through browser management policies from Intune, Google Admin or group policy, which can force-install, pin or block extensions. Updates go through the store or a private update server. This keeps staff from installing unreviewed extensions in place of the approved one.
