| Target Organization | Defencebit |
|---|---|
| Threat Group | thegentlemen |
| Summary | defencebit.com zoominfo.com/c/defencebit/532842616 DefenceBit (founded 2018, Lisbon) is a boutique cybersecurity consulting firm — self-described "hackers, but the good ones" — spun off from Bullray-CIT, an Angolan-government-focused critical-systems integrator. It provides offensive-security services: penetration testing, vulnerability assessments, hardening, source-code and web/API audits, mobile app audits, social-engineering tests and full Red Team engagements, working to PTES/OWASP/OSSTMM standards with manual verification. The team holds top certifications (CEH, CISSP, PMP, Checkpoint CCSE, ISO 27001) and its co-founder later moved to a senior role at the NATO Communications and Information Agency. A notable credential is its contract with Portugal's National Cybersecurity Centre (CNCS) to run the "Cidadão Ciberseguro" course for government workers on the state NAU platform. It remains a very small company (1–10 staff) |
