What MONGOOSE CYBER SECURITY LTD does

Mongoose Cyber Security Ltd is a CREST-accredited penetration testing and corporate assurance consultancy headquartered in Wilmslow, England. The firm delivers specialist, manual-first security assessments to enterprise and mid-market organisations across the United Kingdom, with the buyer typically being an IT Director, CISO, or Risk/Compliance Manager. Services span external and internal network penetration testing, web application and API testing, cloud security assessment across AWS/Azure/GCP, AI/LLM adversarial red teaming, physical penetration testing, full-spectrum red teaming, and social engineering. Compliance-aligned engagements cover PCI-DSS v4.0, ISO 27001:2022, DORA, UK GDPR, and NIS Regulations. The company is incorporated as a private limited company in England (Registered No. 14538046) and is founder-led by a Royal Marines veteran, with no disclosed institutional investors, parent, or subsidiary structure.

The underlying methodology is deliberately human-led rather than automated, anchored in industry frameworks including PTES, NIST SP 800-115, OSSTMM, OWASP Top 10/ASVS, MITRE ATT&CK, CBEST, TIBER-EU, CIS Benchmarks, and the AWS/Azure Well-Architected Frameworks, with physical engagements following NPSA STaMP. The firm differentiates through principal-only delivery (minimum 10,000 manual testing hours per consultant), 90-day complimentary remediation re-testing, and a physical/red team capability staffed by former UK Special Reconnaissance Regiment (SRR) personnel. AI/LLM assessments align with OWASP Top 10 for LLM Applications and the NIST AI Risk Management Framework, and AD CS exploitation (ESC1/ESC2) work is a documented specialist area.

Revenue is generated exclusively through bespoke, project-based engagements priced as fixed-fee proposals scoped by environment complexity (number of IPs, web applications, or physical sites), with typical engagements running 5–15 days and multi-year contracts. Distribution is direct sales only — website, phone, and email — with no self-serve, channel, or marketplace motion. Demand generation is content-led via the company blog (Intelligence section) and LinkedIn presence, targeting UK-regulated buyers in SaaS/Technology, Legal & Financial Services, Manufacturing, Logistics, Retail/E-commerce, Education, Critical National Infrastructure, and Construction. The company holds CREST accreditation for penetration testing and is a CREST member company, is GDPR-compliant with ICO registration, and is co-marketed alongside six Lincolnshire regional partners including the Greater Lincolnshire Combined County Authority and the University of Lincoln.
