More About Nick


Nick started collecting hacking newspaper articles back in the 80's when security was just starting to grow, and was immediately hooked. He is a certified ISC2 instructor, a GIAC advisory board member and has an MSc (with distinction) in Advanced Security and Digital Forensics from Edinburgh Napier University and a BSc (with distinction and the highest held graduation grade of the department) from the Technological Educational Institute of Thessaly. He has a great passion for teaching and has trained many individuals in a variety of security topics, mainly focusing in SIEM, security operation centers, incident response and security certification courses.

Nick has worked for a variety of companies (including the Greek Ministry of Education, AT&T, F5 Networks, JP Morgan Chase, KPMG and Deloitte) and has provided critical advice to many clients that want to improve their current security posture by creating new security operation centers and protocols, developing vulnerability management programs, managing third parties and security vendors, testing incident handling and forensic teams, redesigning perimeter security solutions, and developing custom-tailored training courses for company staff and specialised security teams. One of the greatest challenges for most security professionals is ensuring they have an in-depth understanding of all fundamental concepts of security. Nick loves teaching classes that help students obtain the knowledge required to secure their environments and enhance their personal security posture to protect themselves in an ever-growing digital arena.
