Spiros Antonatos

I've spent 20 years at the intersection of cybersecurity research and industry, moving between academic institutions, EU research programmes, and private organisations.

I started at ICS-FORTH, where I spent years researching web security, network monitoring, and privacy, publishing papers and participating in EU-funded programmes. The more I participated in security research, the more I realised that technology alone isn’t the answer. It’s about people, collaboration, and making security work in the real world.

From there, I moved into the private sector. At IBM Research in Dublin, I worked on security and privacy challenges for customers in healthcare and financial services, including contributing to Truata, one of the first GDPR data trusts. At Tenable, I worked on vulnerability management for OT networks. While working with the Technical University of Crete and Aegis Technologies, I focused on large-scale network monitoring, threat intelligence, 5G core security, and adversarial attack path planning.

I've filed 16 patents and published 25 research papers across web security, network monitoring, threat intelligence, and GDPR-focused data trust.

Across every role, my goal remained the same: leverage my experience to find ways to solve cybersecurity’s problems in a way that actually works in the real world.

I co-founded Cymph to give security teams the visibility and operational capability they need to proactively manage their incident response readiness.
