Dr. Nick Savage

Advisor for EdTech startups

Building cyber security resilience through education

Tech startups and scaleups typically find themselves in a fairly unique and enviable position: they still have the ability to maintain a high innovation velocity! However, this is juxtaposed against a desire to mature development processes and constantly improve quality. It is common for security to be absent or ill-defined in a product’s vision and, subsequently, absent or ill-defined when the product is launched. This product deficit becomes visible when external testing takes place, which can lead to the loss of key contracts or an ever lengthening sales cycle. This talk will explore the delicate balance between maintaining innovation velocity and improving processes; with a particular focus on high risk areas such as cyber security. It will also reflect on compliance drivers and how they can manifest to improve (or hinder!) development velocity.


Dr Nick Savage is an advisor for EdTech startups, helping them accelerate growth and capitalise on market potential. In this role at TryHackMe he has helped them to achieve an annual recurring revenue of greater than 20million USD. He also assists in the due diligence process for investors reviewing tech companies. Previously he was the head of the School of Computing at the University of Portsmouth where he led a substantial growth of research income and vice-chair of the Council of Heads and Professors of Computing in the UK. His technical interests are mostly about networking and systems architectures (at a device and interconnected device level – particularly the vulnerabilities that can result from assumptions regarding how devices interconnect – for example in implementations of BGP/ICMP/SSH/DNS), C and C++ programming (particularly fuzzing and analysing memory corruption vulnerabilities) and in the measurement and modelling of systems. He has deployed large scale (and highly scalable) systems on aws, built and maintained PKI systems and manages vulnerability scanning and monitoring systems. From a governance and compliance perspective, he has successfully led companies through Cyber Essentials, ISO 27001:2022 and SOC 2 Type 2 audits and developed systems according to NIST800-53 and CIS benchmarks. He was a member of Working Group 3 for the European Commission’s Network and Information Security platform directive and has previously worked on projects funded by the Office of Communications, the European Commission and the Engineering and Physical Research Council.

Dr Alexopoulos Argyrios

NATO Cyberspace Operations Center

Cyberspace Activities shortly prior and during Military Kinetic Operations

In modern warfare, digital and physical realms are closely intertwined. Absolute differentiation between Kinetic and Cyber Weapons seems to have strategic implications in modern battlefields. The presentation will highlight, with concrete and recent Open Source examples, the importance of integrating cyber activities prior or during kinetic operations, for optimisation of operational objectives.


Dr Alexopoulos Argyrios, a distinguished professional in the field of Cyber and CIS Security, boasts a remarkable career that spans over 25 years. Currently, he is employed at the NATO Cyberspace Operations Center. Argyrios’s professional journey is marked by diverse experiences across national military organizations, the EU, and NATO, demonstrating his wide-ranging expertise in challenging and security-intensive roles.

His tenure since 2017 at the EU Space Programme Agency and NATO stands out as a particularly unique period. During this time, Argyrios contributed to effective Communications Security operations for what is considered the EU’s most challenging program. Since 2019, he has been serving NATO as a Situational Awareness Analyst, contributing significantly to the organization’s cyber security efforts.

Argyrios’s career is notable for its breadth, encompassing technical, operational, and strategic roles within the complex ecosystems of cyberspace. His dedication to Cyber Security, Information Assurance, Electronic Warfare, COMSEC, and Risk Management, combined with his excellent organizational and technical leadership skills, has made him a key figure in large-scale IT ecosystems. He is highly motivated, committed, and possesses proven communication and interpersonal skills, making him a valuable asset in the international civil-military arena. Argyrios is also deeply engaged in EDT and AI/ML technologies, further enhancing his contributions to the field, and demonstrated a flexible and innovative approach to delivering high-quality results in dynamic and operationally challenging environments, making his career exemplary in the field of cyber security.

Miss Soraya Harding

Senior lecturer in Cybersecurity Intelligence and Digital Forensics, University of Portsmouth

 Strategic Resilience: Safeguarding Critical Infrastructures in a Geostrategic Landscape

The presentation will discuss the complex challenges geostrategic dynamics pose to protecting critical infrastructures. It will explore how organizations can build resilience to withstand and respond effectively to threats, including geopolitical tensions and cyberattacks. It will delve into strategic planning and collaborative approaches necessary for ensuring the uninterrupted functioning of vital systems. Through real-world case studies and actionable advice, organizations will gain valuable strategies to enhance resilience against a myriad of threats, ensuring seamless operations even amidst the most uncertain global scenarios.


Soraya is a highly experienced professional with a strong background in incident response, mobile forensics, computer forensics, and business information system security. Her role as a senior lecturer at the University of Portsmouth suggests that she is involved in educating students in these fields and providing them with theoretical and practical knowledge.

Soraya has worked for Microsoft and CISCO, which underlines her proficiency in industry-leading technologies, and her decision to continue this role on a freelance basis suggests a desire to share her knowledge beyond a traditional classroom setting.

Soraya’s contributions as a coach in cyber competitions like Hackathons, Tryhackme, and Cyber912, where she led students to Second place alongside prestigious universities such as Cambridge, Glasgow, and Royal Holloway of London, underscores her commitment to nurturing the next generation of cybersecurity professionals.
