Named emergency contacts
Both sides name people who can be reached at any time during the testing window.
Stop on request
Testing pauses immediately if your team asks, or if anything unexpected appears.
No destructive techniques
No denial of service, no data deletion, and no changes to production data.
Scope enforced
Systems outside the approved target list are never tested.
Handled with care
Findings and evidence are shared only with the contacts you name.
