Marcus Webb has built his career protecting individuals and organisations from the ever-evolving landscape of digital threats, with particular expertise in mobile device security and personal privacy protection. He earned his Master's degree in Information Security from Royal Holloway, University of London, one of the UK's leading cybersecurity academic centres, before beginning his career at a major defence contractor working on secure communications systems. Marcus subsequently spent eight years in consulting roles at Big Four firms, leading mobile security assessments and penetration testing engagements for financial services and healthcare clients. His technical expertise encompasses encryption standards, authentication protocols, VPN technologies, and malware analysis, always translated into practical guidance that non-technical users can implement. Marcus's methodology combines threat intelligence analysis with user behaviour research, recognising that most security breaches exploit human factors rather than purely technical vulnerabilities. He is passionate about making security accessible, believing that privacy and protection should not require advanced technical knowledge. Marcus writes to empower readers to take control of their digital security through achievable steps that genuinely reduce risk. His articles frequently reference UK-specific threats, including HMRC phishing campaigns and Royal Mail scam texts, as well as relevant legislation like the Data Protection Act and the Computer Misuse Act. He believes that in an increasingly connected world, security literacy is essential for everyone, not just IT professionals.
