From attack evidence to a reviewed fix.
Exact code
A candidate control point with reachability evidence.
Closed path
A proposed repair and the result of the paths tested.
Reproduced
A synthetic attack illustrates one reproducible behavior.
Example fixture: authentication bypassMatched
A candidate code path is reviewed for reachability.
Example: src/auth/session.service.ts:87Fix
Review a proposed repair at the shared control point.
Ownership guard · 3 files · +18 −30Synthetic proposed patch: src/auth/session.service.ts 85 const session = await readSession(ctx); 86 const role = session?.role; 87 - return role === 'admin' ? next() : deny(); 87 + if (!ownsResource(ctx, session)) return deny(); 88 + return next(); 89 }
Proof
A replay records outcomes for the original and selected variants.
Synthetic example: original + five mutations blocked

SIEMEvidence trail
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.
Product & AppSec leaders
Responsible for reducing reachable risk and showing leadership what actually closed.
Security engineering teams
Working beside developers who need the exact file, line, owner, and smallest safe change.
Git-based product teams
Running customer-facing applications through code review and CI, with attacks worth replaying.
Review what changed.
Keep the replay evidence.
This synthetic fixture illustrates one tested path. A passing replay records the selected payloads and environment; it does not establish that every attack is blocked.
