Merlon Security Information

Merlon Security is a sovereign cybersecurity company delivering enterprise-grade security services to organisations that demand uncompromising protection of their digital infrastructure. We operate across two core disciplines: Managed Detection & Response (MDR) and Specialised Testing & Engineering (ST&E). Our MDR services provide continuous monitoring, threat detection and incident response across devices, accounts and networks. Our ST&E team addresses complex security challenges through penetration testing, red teaming, forensic analysis, security consultancy and specialised engineering, including air-gapped environments and data-diode implementations. Sovereignty is not a marketing term for us, but a guiding principle. We believe organisations should retain control over the continuity, security and resilience of their operations, without becoming unnecessarily dependent on third-party vendors. We work with organisations across sectors, including regulated and defence-related environments where information security, technical expertise and trust are critical. Merlon Security combines deep technical capability with collaboration, experimentation and curiosity. Our ambition is to strengthen Europe’s digital resilience by building sustainable, sovereign cyber capabilities.
