    You Can’t Patch Your Way Out of This | Mahdi Abdulrazak & Kim van Lavieren, Dawnguard | Cyber Security District

    What if your infrastructure was built secure from minute one and stayed that way? In this special one year anniversary episode of Cyber Security District, host Jeroen Prinse sits back down with Mahdi Abdulrazak (CEO) and Kim van Lavieren (CTO) of Dawnguard, a security automation platform that turns approved security architecture directly into deployable cloud infrastructure as code. One year in, having just closed a pre-seed round and raised €6.3 million in total funding and opening a new office in New York, Dawnguard is making a bold bet: that the only real answer to modern cyber threats isn't better detection or faster patching, it's building systems that are resilient by design from the very start. Mahdi and Kim have both led security teams inside large organisations and lived through the same recurring nightmare: architecture locked in too early, security reviews arriving too late and a list of 50 findings that nobody has time to fix before the product ships. Dawnguard was built to break that cycle, with a collaborative canvas that lets teams design, validate and deploy secure infrastructure in minutes, with continuous drift detection to make sure it stays that way. One year on, we look back at how far that idea has come and what's next as the company expands. Key Takeaways: You cannot patch your way out of agentic AI attacks, the only answer is building more resilient systems from the start The hardest translation in security is from policy to architecture, ambiguity and contradictions there cascade into every layer below Context is the missing ingredient in most security tooling: secure or insecure is a binary lens that doesn’t reflect reality Drift detection only works when you know what was approved in the first place, that’s the advantage of integrating into the design lifecycle Security decisions still belong to the business and engineers, Dawnguard removes the friction, not the ownership The shift from protection to resilience is already happening: it’s not if you get breached, it’s how contained the blast radius is European founders can compete, but capital conviction from investors matters as much as capital volume Timestamps: 00:00 – Introduction 00:15 – Meet Dawnguard 00:48 – One year in: what proved Dawnguard was solving a real problem 01:30 – How customers are using the platform today: discover, design, deploy, monitor 03:20 – The shift-left moment: when architecture gets locked in and it’s already too late 05:15 – why organisations overestimate their resiliency requirements 06:15 – What Snyk, OPA and Sentinel leave unresolved 08:30 – Guardrails vs. findings: preventing vulnerabilities instead of just reporting them 09:30 – Policy to architecture to code to production: where is the hardest translation? 11:00 – The Mythos era: agentic AI and why patching is a losing strategy 12:50 – The shift from protection to resilience 15:00 – Blast radius reduction and the holistic trade-off view Dawnguard provides 16:45 – Drift detection: how Dawnguard tells a legitimate change from a malicious one 18:20 – Prompting redesigns for cost, sustainability, and resilience 20:00 – Bringing guardrails into the developer IDE in real time 22:25 – Who owns the security decision? 25:45 – European digital sovereignty: what it concretely means for Dawnguard 27:55 – Raising €6.3 million from European funds in year one 29:10 – What excites Mahdi and Kim most about the road ahead 30:40 – Final message: what CISOs should be doing differently a year from now Connect with the guests: Mahdi Abdulrazak: https://www.linkedin.com/in/mahdiabdulrazak/ Kim van Lavieren: https://www.linkedin.com/in/kim-v-0645931b4/ Website: https://www.dawnguard.io/ Follow Cyber Security District: Jeroen Prinse on LinkedIn: https://www.linkedin.com/in/jprinse/ Laurens Jagt on LinkedIn: https://www.linkedin.com/in/laurensjagt/ Website: https://www.cybersecuritydistrict.com/ All channels & newsletter: https://beacons.ai/cybersecuritydistrict

    From Ethical Hacker to Serial Founder | Francisco Nina Rente | Cyber Security District Podcast

    What does it take to build a cybersecurity company not once, but twice from the ground up? In this episode of Cyber Security District, we sit down with Francisco Nina Rente, one of Portugal's most accomplished cybersecurity entrepreneurs. Francisco started his journey as a teenager tinkering with computers and quickly found his way into ethical hacking and open-source security communities. That curiosity became a career, which then led to a company. His first venture grew from a university incubator into a 250-person operation delivering services across 22 countries, before being acquired by a global security group. After years scaling that business from the inside and taking on roles as country manager, CTO and board member, Francisco stepped away to build again. This time, the mission is clearer: help organisations stop just detecting threats and start truly recovering from them. Art Resilia was born out of a conviction that the market was shifting from cybersecurity to cyber resilience, and Francisco positioned the company right at the centre of that shift. Key Takeaways: Cyber resilience is about recovery, not just defence Focus beats opportunity-chasing, especially in the early days of a startup The Commonwealth of a team always comes before individual interest Trust-based security communication outlasts fear-based selling every time Knowledge remains the core differentiator, even in the age of AI Timestamps: 00:00 – Introduction 01:20 – From a family computer to a hacker mindset 04:00 – First paid gig: penetration testing for hardware 05:30 – Building Portugal's first incident response team at university 09:00 – Selling trust, not fear: early media and awareness work 11:00 – Scaling to 22 countries and finding the right investors 15:30 – The acquisition: joining a global security group 20:00 – Growing into CTO and leaving on his own terms 22:00 – The idea behind Art Resilia and reading the market shift 24:30 – The name: "The Art of Resilience" 25:00 – Where Art Resilia stands today: 50 people, 4 countries 27:00 – Why the Netherlands and Benelux? 28:00 – Lessons from 20 years of building: focus, people, pragmatism 33:00 – Culture, remote work, and hiring for values first 40:00 – What's next for Art Resilia in 3–5 years 43:00 – AI in cybersecurity: tool or transformation? 45:30 – Advice for young professionals entering the field 52:00 – Final message to CISOs: protect both business confidentiality and individual privacy Connect with the guest: Francisco Nina Rente: https://www.linkedin.com/in/frente/ Website: https://www.artresilia.com Follow Cyber Security District: Laurens Jagt on LinkedIn: https://www.linkedin.com/in/laurensjagt/ Website: https://www.cybersecuritydistrict.com/ All channels & newsletter: https://beacons.ai/cybersecuritydistrict

    Automating the Boring Parts of Cybersecurity Consulting | Leslie Clement & Erie Berhitu, Clember AI | Cyber Security District

    What if you could clone your best cybersecurity consultant and put them to work on five engagements at once? In this episode of Cyber Security District, we sit down with Leslie Clement and Erie Berhitu, co-founders of Clember AI, an EU-first, AI-native platform built to automate the repetitive, time-consuming work that holds cybersecurity consultants back. Both Leslie and Erie spent years grinding through the same manual loops at major consultancy firms document analysis, gap assessments, risk reports, roadmaps before deciding enough was enough. Rather than build another consulting firm or hire more headcount, they built a platform. Clember AI now enables security consultants to run five or more client engagements simultaneously, with consistent, high-quality output every time. And they did it entirely bootstrapped, no VC, no investor pressure, just product-market fit and a clear-eyed vision of where cybersecurity consulting is heading. In this episode, we explore: How a company getting hacked on day one of the job launched Leslie’s career in cybersecurity The year-long frustration that led Erie and Leslie to build Clember AI instead of another consulting firm Why they chose to stay bootstrapped despite investor interest and why they don’t regret it How Clember AI automates the full consulting lifecycle: document ingestion, gap analysis, risk translation, and reporting Why consistency across junior and senior consultants is a bigger deal than most firms admit The shift from hourly billing to monthly retainers and how Clember keeps consulting firms “interesting” to clients year three and beyond Their vision: becoming the Datasnipper of cybersecurity consulting Why embracing AI is non-negotiable for CISOs and why helping early-stage startups matters for the whole industry Timestamps: 00:00 – Introduction 00:15 – Meet Leslie Clement and Erie Berhitu 01:40 – How Erie got into cybersecurity (and why it wasn’t exactly planned) 02:45 – Leslie’s rough first day: getting hacked with no tech team 04:00 – The shared frustration that sparked Clember AI 06:10 – Why they chose to build a tech firm instead of a consulting firm 08:30 – The first product concept: automating the questionnaire 11:20 – Who Clember AI is actually for: cybersecurity consultancy firms 14:00 – Billable hours vs. scale: how Clember changes the math 17:30 – The shift from hourly billing to monthly retainers and staying interesting in year three 22:00 – Will AI kill traditional consultancy?

    From 3x CISO to Founder: Building the Tool She Always Needed | Jaya Baloo Founder of AISLE™

    What if the real cybersecurity crisis isn’t attackers, but our own backlog? In this episode of Cyber Security District, we sit down with Jaya Baloo, former CISO at major global organizations including KPN, Avast, and Rapid7 and now founder of AISLE™, an AI-native platform designed to not just detect vulnerabilities, but fix them. After years defending complex enterprises from relentless threats, Jaya made a bold move: stepping out of the CISO seat to build the kind of technology she wished she had. Her mission is clear, eliminate the massive vulnerability backlog that leaves organizations trapped in “security theater” instead of meaningfully reducing risk. This conversation goes beyond buzzwords. We unpack why detection without remediation is broken, how AI can be applied responsibly to actually close security gaps, and what it takes to build transformative security products in stealth. In this episode, we explore: Why Jaya left top-tier CISO roles to start AISLE™ The uncomfortable truth about vulnerability backlogs and unpatched systems Why identity failures remain a systemic weakness How AISLE uses AI for detection, remediation, and verification The importance of stealth mode before going public What leadership looks like in an AI-driven cybersecurity era Key Takeaways: Vulnerability management without remediation is incomplete Security technical debt is evolving into a societal-level risk AI must be paired with verification and human oversight Innovation is essential to preserving true defence in depth The best CISOs stay curious and challenge their own assumptions Timestamps: 00:00 – Introduction 01:20 – Jaya’s transition from enterprise CISO to founder 05:45 – The vulnerability backlog problem 10:30 – Why identity failures remain systemic 16:40 – Building AISLE™: from concept to stealth 22:15 – AI for remediation, not just detection 29:50 – Verification, testing, and human-in-the-loop controls 36:10 – Working with design partners and open-source communities 42:35 – The AI shift in cybersecurity 48:20 – Leadership lessons from the CISO seat 54:10 – Final message to global CISOs Connect with the guest: Jaya Baloo: https://www.linkedin.com/in/jaya-baloo-558492/ Website: https://aisle.com/ Follow Cyber Security District: Laurens Jagt on LinkedIn: https://www.linkedin.com/in/laurensjagt/ Website: https://www.cybersecuritydistrict.com/ All channels & newsletter: https://beacons.ai/cybersecuritydistrict

    The AI Deepfake Problem Is Worse Than You Think | Marco Ramilli | 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, 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 Timestamps: 00:00 – Intro 00:14 – Meet Marco Ramilli 01:00 – Hacking the campus network (with a for loop!) 02:15 – Getting caught, and hired for cyber research 03:10 – Reverse engineering malware at UC Davis 04:30 – Cybersecurity in Italy: too early, too expensive 05:45 – Why compliance was seen as a cost 06:20 – Building a company just to be the “owner of his time” 07:00 – Early business struggles & staying focused 08:30 – Why saying “no” saved his startup 10:10 – On embracing failure and learning from loss 11:30 – Curiosity, discomfort, and moving to the U.S. 13:00 – Sleeping on floors and working without backup 14:00 – Founding Yoroi, growing from 4 to hundreds of employees 15:30 – The ransomware era and massive inbound traction 16:45 – Sandboxing: research, papers, and real-world applications 18:00 – Joining Google via acquisition 19:30 – Startup phases and letting go as a founder 21:00 – Hiring advice: don’t save money on great people 23:00 – Launching IdentifAI: how a fake Pope jacket sparked a real mission 25:00 – Building AI to detect AI: early model design 27:00 – From 80% to 96% accuracy in deepfake detection 28:00 – Why images are more dangerous than text 29:45 – The weaponization of synthetic media 31:20 – How IdentifAI detects voice, image, and video manipulation 32:45 – Use cases: banking KYC, insurance fraud, and football scouting 35:00 – API-first strategy and enterprise readiness 36:30 – “Digital Performers” and the ethics of representation 37:30 – Real-time meeting detection via agents 39:00 – Why probabilistic AI is changing the rules 40:00 – How cybersecurity must evolve to deal with uncertainty 43:20 – Deployment flexibility: on-prem or private cloud 46:20 – The philosophical challenge of non-deterministic systems 49:30 – Final message to CISOs: stay curious Connect with the guests: Marco Ramilli: https://www.linkedin.com/in/marcoramilli/ Website: https://identifai.net/ Follow Cybersecurity District: Laurens Jagt on LinkedIn: https://www.linkedin.com/in/laurensjagt/ Website: https://www.cybersecuritydistrict.com/ All channels & newsletter: https://beacons.ai/cybersecuritydistrict

    Rethinking Cybersecurity Architecture with Dawnguard’s CTO Kim van Lavieren

    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.

    The Google Security Gap Nobody Talks About with Florbs founders Niek Waarbroek and Tycho Klessens

    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: The original problem Florbs set out to solve inside Google Workspace Why offboarding is one of the biggest overlooked security gaps How ex-employees still access company data without detection From custom scripts to a full-fledged SaaS product Product-led growth without a sales team or marketing budget Raising €1 million from angel investors and CISOs Going from solo founder to building a complementary co-founder team How they’re building safe, reversible file actions with real-time insights Expanding into AI-powered detection and cross-platform collaboration security Lessons learned transitioning from VC investor to cybersecurity CEO 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.
