Bulletproof

Bulletproof is a well-established UK cybersecurity and compliance services provider headquartered in Stevenage, Hertfordshire. Originally incorporated in 2005 and relaunched as a dedicated cybersecurity firm in 2016, Bulletproof has grown to serve over 2,000 customers worldwide with a team of more than 100 employees, including over 60 accredited penetration testers and consultants. The company delivers CREST-accredited penetration testing across web applications, networks, cloud environments, mobile applications, and wireless infrastructure, alongside red teaming, social engineering assessments, and vulnerability scanning services.

Bulletproof's service portfolio extends well beyond penetration testing into broader cybersecurity and compliance consulting. They offer ISO 27001 and ISO 27701 consultancy, PCI DSS compliance support, SOC 2 readiness, Cyber Essentials certification, GDPR and data protection services, outsourced DPO support, managed SIEM/SOC, managed detection and response, digital forensics, and incident response. This breadth of capability makes them particularly well suited for small and mid-market organisations that need a single provider to address both security testing and regulatory compliance requirements.

In 2024, Bulletproof was acquired by The GRC Group as part of a broader consolidation within the UK cybersecurity market. The company is recognised as an NCSC Cyber Advisor and maintains CREST accreditation, ISO 27001 certification, and Cyber Essentials Plus status. Their testers hold individual certifications including OSCP, OSWP, CISSP, and CISA, reflecting a strong commitment to technical excellence across the team.
