Penetration Testing & Red Teaming is a service offering from Bitcrack Cyber Security covering technical security testing across networks, applications, cloud environments and industrial systems. The service includes internal and external network testing to identify misconfigurations, vulnerable services, weak authentication and lateral movement paths, as well as authenticated testing of web, mobile and API applications for injection flaws, broken access control and business logic issues. Red Team Operations provide full-scope adversary simulation against a defined objective, testing people, processes and detection capability. Cloud Security Assessments review configuration and identity across AWS, Azure and GCP against CIS Benchmarks, including attack-path analysis across roles, keys and trust relationships. The offering also covers wireless and physical security testing (badge cloning, tailgating, reception process testing), and OT, SCADA and IoT assessments using a passive-first methodology with active testing confined to agreed windows or lab replicas. Additional practice areas within this service include incident management and response aligned to NIST SP 800-61, and digital forensics and investigation with chain-of-custody evidence handling to support litigation and regulatory notification. Testing methodology follows a defined process: scope and authorisation, reconnaissance and mapping, vulnerability identification (automated tooling plus manual testing), exploitation and privilege escalation, post-exploitation impact analysis, and reporting with a retest cycle where remediated findings are marked verified. The service aligns to PTES, OWASP WSTG, OWASP MASVS, OWASP API Top 10, MITRE ATT&CK, NIST SP 800-115, NIST SP 800-61 and CIS Benchmarks.</description> <parameter name="summary">Penetration testing and red team service across network, app, cloud, OT and physical assets
