The fix
One control point.
Closed for good.
Cefense doesn't hand you a report. It prepares the smallest safe change at the exact line the attack reaches — with the tests that prove it.
The honest problem
Every scanner can see.
Almost none can close.
The list was never the hard part.
Two hundred findings by Friday, each ranked by a number that means something different in every tool.
Seeing risk is easy. Closing it is the job nobody automated — the reading, the reachability, the one change that actually matters.
A different starting line
Cefense starts where
the list ends.
First, it finds the exact line.
Before there is a fix, there is a match. Cefense traces the observed attack through your repository graph to the precise place it becomes reachable.
The one path that can actually be reached is the one you see. No guessing which of two hundred findings is real.
Then it acts
And it writes
the change.
The real thing
This is the fix, not a mockup.
Repository context. One focused diff. The decision beside it.

One line, if one line
is all it takes.
Every variant crosses one boundary.
An attack wears a hundred disguises and passes through a single choke point — where reachable code becomes a privileged action.
Cefense closes the choke point, not the disguise. Fix the boundary once and every variant stops at the same door.
Nothing else moves
Your login flow
never moves.
The safest fix touches the least.
The most dangerous change is the one that quietly breaks something else. Cefense scopes the repair to the boundary.
It proves the blast radius is empty before you ever see it. No refactor. No sweeping rename.
Proof, not confidence
A fix you didn't test
is a guess.
So it runs the attack again.
Cefense replays the original path and every semantic variant against the change, and watches each one fail to reach the control point.
What you approve has already survived the attack it was written for.
Why it's different
The finding is not
the product. Closure is.
A live attack is reduced to the behavior that made it work.
Traced through the repository graph to the reachable line.
The smallest safe change at the shared control point.
The original and every variant replayed and blocked.
The whole loop
From attack
to proven fix.
Observed, matched, fixed, proven. One path, one chain of evidence, one closed door — kept together from the moment it appears.
