It’s time to get practical. After identifying protect surfaces and mapping flows, the third step in Zero Trust is about designing the actual architecture.In this episode of Threat Talks, Lieuwe Jan and Rob Maas talk about segmentation, control selection, and why this is the most operational step in your Zero Trust journey.They cover:✅ Why segmentation is one of the most important Zero Trust measures🔒 How to choose and assign technical controls (and what matters most)📄 How frameworks like MITRE ATT&CK, ISO 27001, and the Cyber Kill Chain help map risks to controlsFrom translating compliance requirements into actionable controls to whiteboarding micro-perimeters and network segments, this is where the vision meets the real world.Shownotes:⁃ Zero Trust Step 1 episode: https://youtu.be/mC66i-tEEFs ⁃ Zero Trust Step 2 episode: https://youtu.be/wp0q9aZHuXc ⁃ Rick Howard episode on the Kill Chain https://www.youtube.com/watch: v=GC8z3W2OSwQ&t=1s ⁃ Outlook Web Access Deep Dive episode: https://www.youtube.com/watch?v=Bd5mhPiqT5Q 🔔 Follow and Support our channel! 🔔=== ► YOUTUBE: https://youtube.com/@ThreatTalks► SPOTIFY: https://open.spotify.com/show/1SXUyUEndOeKYREvlAeD7E► APPLE: https://podcasts.apple.com/us/podcast/threat-talks-your-gateway-to-cybersecurity-insights/id1725776520👕 Receive your Threat Talks T-shirthttps://threat-talks.com/🗺️ Explore the Hack's Route in Detail 🗺️https://threat-talks.com🕵️ Threat Talks is a collaboration between @ON2IT and @AMS-IX

From sovereign clouds to Zero Trust, and from cross-border investments to threat intelligence sharing, cooperation between the US and Europe is crucial, but still complex. With differing policies, fragmented markets, and varying strategies, the cyber world remains anything but unified.In this special episode of Threat Talks, Davis Hake (Senior Director for Cybersecurity at Venable) leads a discussion with Lisa Hill (Director of Investor Relations at Shield Capital), Chris Painter (the US’s first cyber ambassador and founder partner of the Cyber Policy Group), Lieuwe Jan Koning (CTO and co-founder of ON2IT cybersecurity) and Peter Brown (former EU official and diplomat). Together, they explore where collaboration is gaining ground and where major obstacles still stand. 🌐 How do the US and EU differ in their approach to Zero Trust and prevention?📊 What role does private sector investment play in advancing national security?🔁 Why is threat intelligence still so difficult to share effectively across borders?Tune in for a grounded conversation that connects regulation, strategy, and industry, and shows how both sides of the Atlantic are navigating today’s cyber challenges.🔔 Follow and Support our channel! 🔔=== ► YOUTUBE: https://youtube.com/@ThreatTalks► SPOTIFY: https://open.spotify.com/show/1SXUyUEndOeKYREvlAeD7E► APPLE: https://podcasts.apple.com/us/podcast/threat-talks-your-gateway-to-cybersecurity-insights/id1725776520👕 Receive your Threat Talks T-shirthttps://threat-talks.com/🗺️ Explore the Hack's Route in Detail 🗺️https://threat-talks.com🕵️ Threat Talks is a collaboration between @ON2IT and @AMS-IX

AI vs. Human Pentesting: Who Wins?What happens when you try to automate something that’s part science, part art? In an industry rushing to adopt AI for everything from detection to response, the real question is: can a machine truly replace the craft of a human pentester?In this episode of Threat Talks, host Lieuwe Jan Koning is joined by Melanie Rieback, co-founder and CEO of Radically Open Security, and Luca Cipriano, a red teamer and threat intel specialist. Together, they dig into what makes great pentesting work.Melanie explains why her company donates 90% of profits to open source and operates with a not-for-profit model, and how that connects with their mission to support NGOs and civil society groups. Together, she and Luca share their hands-on experience with pentesting and why creativity, gut instinct, and lateral thinking are still crucial in ethical hacking.They discuss:🤖 Can AI outsmart human red teamers?🧠 What makes great hacking truly human?🔍 What’s still too complex for automation?From tool-assisted testing to old-school intuition, this conversation offers a grounded take on the reality of modern pentesting and what AI can’t do (yet).🔔 Follow and Support our channel! 🔔=== ► YOUTUBE: https://youtube.com/@ThreatTalks► SPOTIFY: https://open.spotify.com/show/1SXUyUEndOeKYREvlAeD7E► APPLE: https://podcasts.apple.com/us/podcast/threat-talks-your-gateway-to-cybersecurity-insights/id1725776520👕 Receive your Threat Talks T-shirthttps://threat-talks.com/🗺️ Explore the Hack's Route in Detail 🗺️https://threat-talks.com🕵️ Threat Talks is a collaboration between @ON2IT and @AMS-IX

PLCs with default passwords. Devices searchable online. Siloed asset inventories. These OT challenges are common, but they’re also fixable. In this episode of Threat Talks, host Lieuwe Jan Koning sits down with Venable’s Caitlin Clarke and Schneider Electric’s Patrick Ford to discuss why the OT side of your business deserves the same focus and attention as IT. From default passwords to exposed PLCs, they show how these ‘tech risks’ span beyond just OT and IT. They discuss:✅ How to replace "default" thinking on OT security🌐 Spotting internet-facing assets before attackers do🔍 Using CISA’s Installed Base Initiative to locate orphaned tech🤝 Building joint response plans across IT, OT, and governmentOrganizations are getting ahead of risk by building live OT inventories, applying smart controls, and partnering with federal teams to strengthen critical infrastructure.

Once you have defined a few protect surfaces (see: ⁠Step 1 of Zero Trust-video link below⁠), the next step is to start mapping the transaction flows: how these protect surfaces communicate with one another.

Understanding how data travels to, from and around protect surfaces is your next logical movie. Why? Because if you don’t know how your systems talk to each other, you can’t secure them.

In this episode of Threat Talks, host Lieuwe Jan Koning and Field CTO Rob Maas discuss how to identify communication paths between protect surfaces and why this visibility is critical for both risk containment and policy validation.

They explore:

✅ How to identify communication paths

⛕The difference between inbound and outbound traffic (and why this matters)

🙋🏼‍♂️Why business owners and business context are essential

Get all the details and

insights on this second step of Zero Trust: mapping the transaction flows.

Now that we know what a PLC, HMI and SCADA are (check out last week’s episode for a refresher if you need one!), we’re ready for part two of our OT deep dive: how does an OT attack work? In this Deep Dive, Rob Maas and Luca Cipriano break down just how complex an OT attack really is. From needing to stay hidden, to requiring access to very specific system settings and blueprints; setting up a successful OT attack (thankfully) is no easy task. But does that mean it’s easier to defend against them?Key topics:⚙️ How IT and OT attacks differ☠️ What the ICS cyber kill chain is🌎 How OT attacks can impact whole nationsJoin Rob and Luca for a discussion on the motivations behind OT attacks, how to bridge the gap between cybersecurity and engineering, and what we can do to prevent these high impact OT attacks.

From heating systems in Ukraine to petrochemical plant safety controls, Operational Technology (OT) systems are the hidden workhorses behind critical infrastructure: and they're wide open to cyber threats.

In this Deep Dive, Rob Maas sits down with Luca Cipriano to break down what OT is, why it’s different from IT, where the two overlap and how we can start securing both before it’s too late.

Key topics:

⚙️ What OT is (and isn’t)

📉 Why IT and OT often don’t speak the same language

🛠️ Real-life OT cyberattacks (hello, FrostyGoop and TRITON)

Welcome to OT 101: explained in plain language, with a healthy dose of practicality.

From ships and cities to hospitals and airports, Operational Technology (OT) keeps the world running. The problem? It was never designed with cybersecurity in mind.

In this episode of Threat Talks, host Karin Muller is joined by TC Hoot (VP of Contracts at TAC) and Luca Cipriano (Threat Intel Specialist at ON2IT) to explore how airports, hospitals, ports, and even water systems can be compromised.

Key topics they tackle:

🛳️ Why are modern ships, airports, hospitals and even cities targeted?

🛡️ What makes OT so hard to secure compared to IT?

✈ What do real-world OT threats look like and how can we defend against them?

If you’ve ever asked “how could a fish tank lead to a casino breach?” or “can someone actually hack an airport’s baggage system?” this one’s for you.
