Web app security audits

Let us find the risks before the hackers do.

Most data leaks don't take a genius hacker. They take one page that shows a customer something it shouldn't. We find those gaps in your website or app and help you close them.

What we check

  • Web app security audit

    We sign in the way your customers do and test whether anyone can see or change data that isn't theirs. Those are the gaps automated scanners usually miss.

  • Code review

    We read the code behind your app, including anything written by AI tools or a developer who's moved on, and flag the risky parts. We'll explain what each one means for you.

  • Penetration testing

    With your written permission, we try to break in the way a real attacker would, then show you exactly how we got in.

Below is a sample web browser open to a fake online store. We'll show you how simple a serious security risk can be. Don't worry about breaking anything, it's all pretend.
