This one is a story — an illustrative one. Picture a fintech with a funding round riding on its security review, and ten days to find out what an attacker could reach.

Chapter 1
The situation
Imagine a fintech preparing for a security due-diligence review before a funding round. Investors want independent evidence that customer financial data is protected.
Chapter 2
What a test like this typically finds
Across a web app, its APIs and the external network, a result such as 30 findings — a few of them critical or high — is common. Typical themes are authorization checks enforced in the app rather than on the server, long-lived session tokens, and missing rate limits on key endpoints.
Chapter 3
How it typically ends
The team fixes the critical and high issues with our guidance, we verify the fixes in a free retest, and the company goes into its review with retested evidence instead of open issues.
Chapter 4
What made the difference
Testing the web app, APIs and network together showed how small issues in one area combined with gaps in another. Sharing critical findings during the test gave the developers a head start on fixes.
Chapter 5
What other teams can learn
Test well before a deadline, include the APIs behind your apps, and plan time for a retest. Clear, retested evidence is far more convincing to investors than a promise to fix things later.
Illustrative scenario — hypothetical figures, not a specific client engagement.
Key takeaways
- A focused 10-day test can surface dozens of findings.
- Authorization gaps are often the most serious issues.
- Retested evidence is what reviewers trust.
