In this episode, we cover: Chris’ founder journey: from Binck Bank scale-up years to building Ohpen for 10 years What “security-first” looks like in fintech, non-negotiables, resilience, and trust with enterprise buyers Execution culture, exceeding expectations, hiring for discipline, and why culture beats product The shift to investing and why he started a cyber fund and what he looks for in founders What’s next in AI-driven risk, compliance + security convergence, and Europe’s digital sovereignty challenge Timestamps: 00:00 – Intro 00:14 – Meet Chris Zadeh 01:59 – Growing up without financial safety nets 03:14 – Joining BinckBank at 23 06:52 – Scaling to market dominance 08:57 – Wanting to sit at the decision-making table 11:36 – Early infrastructure and security lessons 14:18 – A firewall shutdown incident 17:55 – Leaving to build Open 18:48 – The vision for cloud-native core banking 22:29 – 744 pages of rejection before first contract 27:14 – Migrating €15B live 28:09 – Security as non-negotiable 32:15 – Hiring discipline and execution mindset 35:05 – Culture: exceed expectations or leave 37:35 – The cost of extreme execution 41:21 – Transitioning to investing 44:27 – Why he rejects the “solo entrepreneur” myth 49:35 – Launching the cybersecurity fund 51:16 – AI, compliance, and new cyber opportunities 58:55 – European cloud sovereignty 01:04:03 – Signal message to CSOs: stay curious 01:06:00 – Outro Connect with the guest: Chris Zadeh: https://www.linkedin.com/in/chriszadeh/ Dark Red (Cyber Fund): https://www.darkred.at/ 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

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
