Application security testing

Find the holes in your app before someone else does.

Plumbline points an AI penetration tester and three proven scanners at your code, checks their findings against each other, and shows you what is new, what is fixed and what still needs work.

How a scan works

From a repository to a list you can work through.

  1. 01

    Give us the code

    Upload an archive or point us at a public GitHub repository. Before anything runs, you confirm you are allowed to test it.

  2. 02

    Four checks, same files

    An AI agent probes the app the way an attacker would and writes proof for what it finds. Semgrep looks for unsafe code, Trivy for dependencies with known vulnerabilities, Gitleaks for passwords and keys left in the code.

  3. 03

    Findings are cross-checked

    When the AI and a scanner flag the same problem in the same place, it is marked confirmed. Those are the ones to fix first.

  4. 04

    Each scan is compared to the last

    You see what is new, what is still open and what you fixed. Mark something a false positive once and it stays dismissed.

Why two opinions

AI is good at finding problems. It is also good at being wrong.

An AI tester can string small weaknesses together into a real attack, something a rule-based scanner will never do. It can also report problems that are not there. Scanners are the opposite: predictable and narrow, and blind to anything their rules do not describe.

Plumbline runs both on the same code and tells you where they agree. Agreement is the strongest signal you can get without a person reading every line.

What you get

Results that slot into the work you already do.

A report nobody opens fixes nothing. Every finding comes with what it takes to close it, and every scan feeds the tools your team already uses.

Findings you can act on
Severity, the exact file and line, the package version that fixes it, and the steps to fix it.
A history for every project
Findings over time, with new and fixed counts for each scan, so you can see whether things are getting better.
Exports that fit how you work
CSV, a Jira import file, and SARIF for the GitHub security tab.
A gate for your pipeline
Fail a build on new high-severity issues without blocking on old ones you have already accepted.
Your own AI key, if you want it
Run scans on your own Grok account. Keys are encrypted and never shown again after you save them.

The ground rules

We only test what you are allowed to test.

Every project needs an authorization statement before its first scan, and it is kept on record with a timestamp.

Secrets we find stay secret.

A leaked key is reported by file and line. The value itself is never stored.

Scans run in a throwaway workspace.

The working copy used for a scan is removed when the scan ends. The results are what we keep.

Want your app checked?

Book a short call and tell us what you are building and where the code lives. We will set up a first scan and talk through what it finds.
