BEFORE WE START
Good questions.
Clear answers.
Know what to expect before an assessment, an exposure review or your first course.
What do you need before testing starts?
Written authorization, an agreed list of in-scope assets and rules of engagement. We agree testing windows, excluded systems and emergency contacts before any active testing.
How long does an assessment take?
Timing depends on the number of applications, roles, APIs and environments. Send us a short scope and we will propose a schedule. We do not promise a fixed turnaround before reviewing it.
What will I receive?
The agreed deliverables typically include an executive summary, validated technical findings, impact explanations and prioritized remediation guidance. Any retesting or ongoing monitoring is defined in your engagement scope.
Will my information stay confidential?
Do not send credentials, logs or sensitive documents through this public form. We can arrange a confidentiality agreement and an appropriate transfer method before receiving assessment materials. Enquiries are restricted to administrators and retained for up to 90 days.
Does a leak count confirm a breach?
No. These are indexed records, not unique people or verified incidents. The datasets may overlap. An index date is not an incident date, and zero matches does not prove a domain is safe.
How does ongoing exposure monitoring work?
Sign in using your SentX Academy account, verify control of a domain with a DNS TXT record and opt in to monitoring. Active verified domains are scheduled for daily count checks, subject to provider availability and quota. History and change notices stay in your private workspace; email delivery requires the email service to be configured.
Can I join a course now?
You can view all three 30-module curricula and apply through the academy. Applications are reviewed before access is granted. Lesson availability, instructors, cohort dates, duration and fees are shown only when confirmed.
Is a course certificate an industry certification?
A SentX Academy completion certificate is issued according to the course's published learning and assessment requirements. It is not an OSCP, CEH or other third-party certification.
