Patch smarter, not harder.
Lieuwe Jan Koning and ON2IT Field CTO Rob Maas break down why “patch everything now” isn’t a strategy, but a risk multiplier. In this session, they teach a practical patching strategy: know your assets, patch edge first, stage updates, and use Zero Trust segmentation to choke off exposure so you only patch what truly matters: fast, safely, and without outages.
Key Topics Covered
· Why “patch everything immediately” fails; availability vs. security
· Staged deployments and rollback safety for crown-jewel services
· Zero Trust segmentation to reduce urgency and shrink attack surface
· Priority signals that matter: asset criticality, exposure, KEV, CVSS

How solid is your digital trust—or are you just hoping your PKI is secure?
Let’s be honest: too many companies run on borrowed trust and forgotten certificates. In this episode of Threat Talks, ON2IT’s Lieuwe Jan Koning and Rob Maas pull back the curtain on what really holds your digital world together—and what can tear it down overnight.
They break down PKI in plain language: the root of trust that must stay locked away, the intermediates that keep your systems running, and the automation that stops your team from clicking “ignore” on yet another warning.
You’ll see why rolling your own keys beats trusting anyone else, how to keep your devices speaking the same language of trust, and why short-lived certificates might just save you from the next big breach.
This isn’t theory—it’s how Zero Trust really starts: by proving that your organization can trust itself.

One unlocked phone can unravel the defenses of a billion-dollar enterprise—because in cybersecurity, small mistakes don’t stay small for long. Attackers can read notes, steal IDs, or impersonate you on WhatsApp. A reused password can launch a remote tool that looks completely legitimate.
Rob Maas (Field CTO, ON2IT) and Luca Cipriano (Cyber Threat Intelligence Program Lead, ON2IT) reveal how poor cyber hygiene erodes trust, endangers partners, and weakens enterprise defenses.
CISOs, CIO and IT managers remember: in a Zero Trust world, your weakest link might not even be inside your organization.

The internet promised freedom. Now it monetizes you. The trade-off? Convenience for control.
In this episode, Lieuwe Jan Koning and Prof. Jacobs reveal how scattered tools like meta and X create security gaps—and how one policy, fewer interfaces, and less data shared cut exposure and keep operations running.
Real examples you’ll hear:
• The neighborhood chat stuck on WhatsApp—and how switching to Signal breaks dependency.
• How your address book upload leaks other people’s data to platforms.
• Why secure doesn’t mean private on platforms that profit from your data.
• Age checks done right: passport chip + selective disclosure instead of oversharing.
• Patient groups and municipalities using PubHubs for private, verified rooms (no ads).
• Continuity risk in the real world: federated login outages, US-dependent authenticators, transatlantic cable cuts, and a court moving email to ProtonMail to stay operational.

Boards don’t buy dashboards—they buy assurance. Breaches are late-stage symptoms of drift: rules pile up, logs lose signal, cloud/Kubernetes outpace governance. Lieuwe Jan Koning (ON2IT Co-Founder) and Rob Maas (Field CTO) show how Zero Trust Step 5B (Maintain) proves your controls still work—today.

Hacktivists don’t need zero-days to hurt you—they weaponize people. Host Lieuwe Jan Koning sits down with Yuri Wit (SOC analyst) and Rob Maas (Field CTO) to dissect APT Handala: how they hunt targets, deliver wipers, and brag about leaks. We map their moves to the Lockheed Martin Kill Chain and turn it into a Zero Trust defense playbook you can actually use—today.

First documented case: AI inside the breach.
Promptlock marks the first time malware has used AI during execution, not just in preparation. In this Threat Talks deep dive, Rob Maas (Field CTO, ON2IT) sits down with Yuri Wit (SOC Analyst, ON2IT) to break down how it works: a Go loader calling an attacker’s LLM in real time, generating fresh payloads that adapt on the fly.
This episode strips away sci-fi hype. You’ll see the psychology of an adversary that thinks mid-attack—and the Zero Trust defenses that box it in. When AI runs inside the kill chain, malware doesn’t just evolve. It crosses into super-malware.
Key Topics Covered
• The first documented case of AI inside the breach — why Promptlock changes the game
• Promptlock’s core loop: calling an LLM mid-attack to generate fresh payloads.
• Why hash-based detection breaks against AI-powered malware detection, ever-changing scripts.
• Behavioral defense over signatures: EDR/XDR, sandboxing, and SSL inspection.
• Zero Trust in practice: block script interpreters, restrict egress, and shrink blast radius.

Your tools say “secure.” Your headers say “leaking.”
In this Threat Talks Deep Dive, ON2IT’s Luca Cipriano (CTI & Red Team Lead) exposes Data Bouncing—a stealthy exfiltration trick that hides inside HTTP headers and abuses DNS lookups through trusted third parties. We show the demo, decode the psychology of the attack, and translate it into Zero Trust moves you can deploy today.

Playing it safe with AI sounds smart, but is banning it really how you prevent data leaks?
In this episode of Threat Talks, ON2IT’s Lieuwe Jan Koning (ON2IT Co-Founder) sits down with Rob Maas, Field CTO at ON2IT, to tackle the hard question: How can CISOs and security leaders embrace AI safely—without exposing their organization to destructive data leaks?
From Samsung’s ChatGPT ban to real-world AI hallucinations, we unpack why “AI, play it safe” doesn’t mean blocking innovation—it means controlling it.

Zero Trust step 5A is where monitoring turns raw logs into decisive action.
Hosts Lieuwe Jan Koning and Rob Maas (Field CTO, ON2IT) expose why MDR alone isn’t protection—and how context closes the gap. Learn to inspect every event, use Indicators of Good/Compromise, and set Rules of Engagement that stop lateral movement and alert fatigue.

Russia’s most notorious cyber unit—Seashell Blizzard (also known as Sandworm, APT 44 and Iron Viking)—has taken down shipping giants, Olympic systems, and Ukraine’s power grid.
In this Threat Talks deep dive, Lieuwe Jan Koning, Yuri Wit (Red Team), and Rob Maas (Blue Team) reveal exactly how these attacks unfold, why they’re so hard to stop, and how Zero Trust can tip the balance back to defenders.
