For the BrowserStack Community
You test how it looks. AllScanTool tests what the code actually does.
We scan, then we forget. You keep what you want.
Your suite is green. It renders pixel-perfect on Chrome, Safari, and a rack of real devices, the end-to-end flows pass, and the build is cleared for release. But functional and visual testing answers one question — does it behave the way the spec says? — and security is a different question entirely: what else can this code be made to do? A login form can pass every cross-browser and regression test while concatenating input straight into a SQL query. A component can look perfect on every viewport while writing untrusted data to innerHTML. A passing QA run is not a safety certificate. AllScanTool adds the missing check: paste the source under test and the Delivery-Layer Engine flags SQL injection, XSS, hardcoded credentials, and insecure functions — each with the line number, a severity, and a concrete fix — before the release goes out. It runs in your browser and forgets your code the moment you leave. No logs. No storage. No retention. Your code stays private.
A passing test confirms behavior. It says nothing about safety.
These are the gaps where code clears the QA pipeline clean and still ships a vulnerability to production.
Functional tests confirm behavior, not safety
A test proves the feature does what the ticket says. An injection or XSS flaw is extra behavior the spec never described — so no assertion ever checks for it.
Cross-browser green on a vulnerable form
A login or search field can render and submit perfectly on every browser and device while passing input straight into an unparameterised query underneath.
Visual regression misses DOM XSS
Pixel-diff and snapshot tools confirm the layout looks identical. They cannot see that the component reached the screen through an unsafe innerHTML sink.
Test configs and fixtures carry real secrets
Hardcoded API keys and tokens slip into test setup, mock servers, and fixtures — then ride along into the repo and the build the QA team just signed off.
“Passed QA” reads as “safe to ship”
Once a build is marked green, the org treats it as cleared. Without a security pass, the sign-off quietly vouches for something it never actually tested.
The release gate has no security step
Functional, performance, and compatibility gates are all in the pipeline. The one check that asks “is this code exploitable?” is missing from the definition of done.
Ask AST
The questions QA engineers and developers run into at the release gate — answered with the specific line, the severity, and the fix.
QThis build passed every functional and cross-browser test — what security issues would those tests never catch?
Behavioral tests assert what the code should do, not what it can be tricked into doing. Paste the source and AST flags the injection, XSS, and unsafe calls that live outside your assertions — with the line and a fix — so “passed QA” means safe too.
QThe login form works perfectly on every device — how do I know it is not vulnerable to SQL injection?
Rendering and submitting correctly says nothing about how the input is handled server-side. AST checks whether the field value reaches a query unparameterised, marks the severity, and shows the bound-parameter fix before the form ships.
QMy visual regression suite is clean — can a component still have an XSS vulnerability?
Yes. A pixel-perfect render can still arrive via innerHTML or dangerouslySetInnerHTML with untrusted data. AST traces that path, flags the sink, and shows the escaped alternative that looks identical and is safe.
QWe are about to sign off a release — are there hardcoded credentials hiding in the test setup or app code?
Paste the code and AST flags API keys, tokens, and connection strings inline in fixtures, mock servers, configs, or the app itself — with the line — so they are pulled before the build you certified reaches production.
