Episode notes

In this episode of Cyber Security District podcast, we speak with Marco Ramilli, a cybersecurity visionaire, TEDx speaker, and founder of IdentifAI, a deepfake detection company working at the intersection of AI, trust, and digital identity. From writing early sandboxing papers to leading cyber defense teams and selling his previous startup to VirusTotal (Google), Marco has spent the last two decades safeguarding digital borders.

At IdentifAI, he’s now taking on one of the biggest threats of the AI era: manipulated content. Whether it’s fake insurance claims, fraud in football scouting, or synthetic identities onboarding to banks, his platform uses AI to detect AI: verifying whether images, voices, or videos were generated by humans or machines.

In this episode, Marco shares his founder story, why he believes the shift from deterministic to probabilistic computing will reshape cybersecurity, and how his latest startup scaled to enterprise use cases within a year.

In this episode, we cover:

Marco’s hacking origin story and first run-in with his university
Researching malware and voting systems at UC Davis
Founding his first cybersecurity company in Italy when the market wasn’t ready
Bootstrapping a business through 3+ years of break-even before momentum hit
Early ransomware response and reverse-engineering threats
Getting acquired by Tinexta and integrating into VirusTotal
Building IdentifAI to detect deepfakes using AI-powered forensics
From onboarding fraud to football scouting scams, real use cases
The rise of “digital performers” and the ethics of synthetic content
Why deterministic cybersecurity tools are no longer enough
The philosophical shift security teams must make to handle probabilistic models
Advice for scaling startups, hiring A-players, and letting go as a founder
His signal message to CISOs: curiosity will save us
