Frequently asked questions
How long does a penetration test take?
Most engagements take 2–4 weeks from kickoff to final report. Active testing runs 5–10 business days depending on scope. Urgent timelines can be accommodated.

What certifications do your testers hold?
OSCP, OSCE, OSWE, OSEP and CRTO, among others. Bit Sentinel is ISO 27001 certified and Trusted Introducer accredited.
Do you retest after we fix the findings?
Yes. Every engagement includes a free retest to verify your remediation, followed by an updated report and attestation letter.
