Defence Logic Limited

Defence Logic is a UK-based cybersecurity consultancy helping organisations protect critical systems, meet regulatory requirements, and respond effectively to cyber threats. We work with SMEs, regulated businesses, and technology partners across multiple sectors, providing practical, end-to-end cybersecurity services grounded in real-world delivery. Our core services include penetration testing, security reviews, and continuous security monitoring. We conduct internal and external network testing, web and application testing, and advanced social engineering assessments that expose real operational risk. These engagements regularly uncover credential compromise and access pathways that traditional controls miss. Defence Logic also delivers a SIEM and SOC capability designed specifically for SMB and SME environments. Our monitoring services are aligned to the MITRE ATT & CK framework and the Cyber Kill Chain, enabling early threat detection, rapid investigation, and effective response. In addition to technical security services, we support governance, risk, and compliance initiatives including ISO 27001, Cyber Essentials, Cyber Essentials Plus, and virtual CISO advisory. Our approach is simple and proven: Protect. Detect. Respond.
