Signals intelligence, open-source investigation, and the cyber dimension of state-aligned threats.
Marcus serves as Technical Director for the firm's cyber security practice. His background combines deep technical expertise in signals and open-source intelligence (OSINT) with extensive operational experience in defending critical national infrastructure against state-aligned actors.
His earlier career included analytical positions in national-level cyber agencies and lead-investigator roles for several high-profile attributions of state-sponsored intrusion campaigns. He has worked extensively on the security of energy, telecommunications, and financial-sector infrastructure, and led multidisciplinary teams combining threat intelligence, incident response, and policy analysis.
At Aethelgard, Marcus advises clients on threat modelling against sophisticated state-aligned actors, the resilience of digital assets under sustained pressure, and the integration of cyber considerations into broader strategic and procurement decisions. His approach combines technical rigour with a clear-eyed understanding of the geopolitical motivations driving cyber operations.
He oversees the firm's cyber security audit methodology and provides expert counsel on secure communication frameworks for sensitive engagements. He maintains current professional certifications and operates with appropriate national clearances.
