When did you last read your own authentication code as if a stranger had written it? Most security holes are not clever. They are ordinary lines that looked fine on the day: a query built by joining strings, an error message that says too much, a key committed in a hurry. The Vulnerability Analyzer reads pasted code and points at the ones that matter.
Vulnerability Analyzer separates the lines that matter from the ones that merely look alarming. Every weakness it keeps comes back with the risk spelled out and a fix, trimmed to whatever you set the Severity Filter to.
What is Vulnerability Analyzer?
Vulnerability Analyzer is a code review tool with one focus: what somebody could do with what you wrote. You paste a file, a function or a description of the system, and findings come back, each naming the weakness, the risk it creates and a way to close it. Nothing is executed, connected or scanned. It is a careful read of text you supply.
Why You Stop Seeing Your Own Code
You wrote the query, so you know exactly what goes into it. That confidence is the one thing a reviewer does not have, and it is why the same few problems survive months of self review:
- Input you trust because you know where it comes from today
- Error messages that say far too much when something goes wrong
- A dependency added once and never looked at again
The Vulnerability Analyzer reads the code the way a stranger would, with no memory of why you wrote it that way.
How Does Vulnerability Analyzer Work?
Paste the code or describe the system, then generate. Findings arrive with the risk and the fix, and with a rewritten version of the affected lines while Show Secure Code stays on.
Four settings shape the report. Security Focus narrows the pass to one area, Injection or Secrets when you already know what you are hunting, and General is the right first run. Severity Filter set to High & Above keeps a long report readable. Output set to Findings + Fixes suits a working session, Report suits something you attach to a ticket, and Checklist suits a review you repeat. Map to OWASP is off by default, so switch it on when a finding needs a recognised label. The Strictness slider starts at 70 percent.
Caution A clean report is not a clean bill of health. The tool only sees what you pasted, so a missing check in a file you left out is still missing.
Confirm A Finding Before You Raise It
Every finding is a claim about code the tool cannot run. Checking one takes a few minutes, and it is the difference between a useful report and noise.
| Finding | How to confirm it |
|---|---|
| Injection in a query | Trace the variable back to the request, then check whether your driver really parameterises it |
| Hard coded secret | Search the repository history, because deleting the line does not remove the commit |
| Vulnerable dependency | Compare the version you have installed against the published advisory |
What it does well
- Catches the pattern bugs a tired reviewer skims past
- Explains why a finding matters, not only where it sits
- Rewrites the risky lines when Show Secure Code is on
What to watch for
- It reads a paste, so anything outside that paste is invisible
- False positives happen, and each finding still needs confirming
- It cannot test a running application, only the text you gave it
Not one page here asks you to register first. EizTools keeps every tool free, and the model behind each generation is yours to choose from the selector. Security work rarely stops at the code, so once your findings are written up, the Compliance Monitoring Tool helps you track the controls around them. Download the report as TXT when it has to travel into a ticket.
Frequently Asked Questions
Does the Vulnerability Analyzer scan my live site?
No. It never connects to anything. It reads the code or description you paste and writes findings back, so testing a running system remains a separate job with different tools.
How accurate are the findings?
Treat them as leads. Pattern based issues such as injection and hard coded secrets are usually spotted well, but the tool cannot see your framework's protections, so confirm each finding in your own code.
Can it map findings to OWASP?
Yes. Map to OWASP sits in the advanced options and is off by default. Switch it on when a finding needs a recognised label for a ticket, a policy document or an audit trail.
Which files should I paste in?
The file holding the risky logic, plus the code that calls it. Input handling, query building and permission checks matter most. Remove real secrets and credentials before pasting anything anywhere.
Security review works best when somebody who was not there reads the code, and that person is rarely free on the day you need them. Paste the file you are least sure about into the Vulnerability Analyzer above, confirm what it finds, and fix the ones that hold up under a second look.
