How Cefense works

Real attacks become proven code fixes.

01Observed

Real attack

One behavior reconstructed from the live security web.

02Matched

Exact code

The reachable control point in your repository.

03Proven

Closed path

A focused repair and replay evidence that it no longer resolves.

THE IMMUNITY LOOP

01

Observed

A live attack becomes one reproducible behavior.

Authentication bypass reconstructed from the network.

Replay fails across the original and six variants.

Evidence recorded · path no longer resolves

The path is closed.

Observed attack, matched code, focused fix, and replay evidence—kept together.

Open Cefense

Evidence, not alert volume

One attack. A complete path to closure.

The immunity loop

Security evidence that stays attached to the code.

A replay is useful only when it tells the team where the behavior lands, what to change, and how to prove the path no longer resolves.

01 / Observed

Start with what actually happened.

Turn a live behavior into one reproducible fixture instead of another abstract severity label.

Close the shared boundary. Replay the variants.

Keep the patch, changed files, original fixture, and closure result together for review.

Ideal customer profile

For teams that own the path from risk to repair.

Cefense is built for software companies with real production code, a security team close to engineering, and no patience for findings that stop at a dashboard.

01 / Buyer

Product & AppSec leaders

Responsible for reducing reachable risk and showing leadership what actually closed.

02 / Operator

Security engineering teams

Working beside developers who need the exact file, line, owner, and smallest safe change.

03 / Environment

Git-based product teams

Running customer-facing applications through code review and CI, with attacks worth replaying.

Best fitGrowing software teams where one shared control point can close many variants.Not another static scanner. Not a one-off report. A repeatable path from observed behavior to proven closure.

The honest problem

Every scanner can see.
Almost none can close.

This page uses a synthetic fixture so the product story is testable: start with a request, trace the reachable code, review the patch, and run the same behavior again.
