Research, strategy and practical cybersecurity.

I am Prof. Dr. Šarūnas Grigaliūnas, a cybersecurity professor and Head of the KTU Cyber Security Centre of Excellence.

My work connects academic research with the practical security problems faced by public institutions, critical infrastructure, finance, technology organizations and high-trust sectors.

I have been working in cybersecurity since 1999. Over that time, the field has moved from perimeter defence and incident response to a much broader challenge: protecting digital trust in a world shaped by artificial intelligence, quantum technologies, complex supply chains and geopolitical pressure.

* Professional identity

I work where research, governance and implementation meet. My professional focus is not only to study future threats, but to translate them into decisions, frameworks, training, infrastructure and readiness measures that organizations can actually use.

* Strategic areas

Quantum-era cybersecurity

Post-quantum cryptography, crypto-agility, quantum-safe identity, QKD and cross-border quantum communication infrastructure.

AI security governance

Organizational readiness for AI-related security risks, accountability models, CARI and the CAISO concept.

Digital forensics

Cybercrime investigation, digital evidence, incident reconstruction, OSINT and forensic readiness.

Critical-sector resilience

Practical cyber risk management, incident readiness, executive decision support and security governance.
