Topic areas

Security and module risks we investigate

01

Admin authorization boundaries

Validate that ACL resources, controller enforcement, and role behavior produce deterministic denied access where required.

02

Custom module exposure

Identify backend routes, actions, and module features that can expose sensitive operations without explicit authorization testing.

03

Role and permission drift

Detect production role configurations and stored rule states that diverge from expected least-privilege access behavior.

04

Security verification workflow

Strengthen deployment QA with allowed/denied role testing, direct URL checks, and repeatable access-control verification steps.

Module risk?

Need clarity on custom module security risk?

A forensic platform audit can evaluate custom Magento modules, Admin access controls, extension exposure, authorization behavior, and the technical risks affecting sensitive platform operations.
