Cyber Security District

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 of Cyber Security District, we sit down with Kim van Lavieren, co-founder and CTO of Dawnguard, a cybersecurity startup that raised millions in funding before registering a company or launching a product. Kim’s story is anything but ordinary, from leading Marines on no-sleep missions to building offensive hacking tools for the Dutch military, to managing massive security teams at Amazon in the U.S., his path combines discipline, vision, and deep technical mastery.

Together with co-founder Madi Abdurazak, Kim is now on a mission to completely rethink how cybersecurity should be done, by starting not with alerts or vulnerabilities, but with architecture, policy, and real business risk. Dawnguard is building a platform that automates secure-by-design architecture using AI, aiming to replace an entire category of cloud security tools before most companies even realize there’s a better way.

In this episode of Cyber Security District, we sit down with Niek Waarbroek (Founder & CTO) and Tycho Klessens (CEO) of Florbs, a Dutch startup transforming file security inside Google Workspace. What started as a simple set of admin scripts has evolved into a powerful SaaS platform, used by global enterprises to automate onboarding, offboarding, and prevent accidental (or malicious) data leaks.

Niek shares how his frustrations with error-prone onboarding flows inspired him to build smarter tools, and how a lack of visibility into shared files became a real security threat for many organizations. After bootstrapping Florbs for three years, he crossed paths with Tycho, then a VC investor, who not only became the commercial co-founder, but helped raise €1 million to scale the team.

Together, they discuss the power of building with product-led growth, how they’re scaling without wasting capital, and why real file security goes beyond Google’s default settings. They also explain why early-stage cybersecurity startups need more than funding, including focus, clarity, and the right partner chemistry.

In this episode, we cover:

Whether you're a CISO, founder, or operator working in Google Workspace or building a startup yourself, this episode shows how automation and visibility can finally close one of the biggest blind spots in modern file security.
