The Importance of Red-Teaming and Cyber Risk Quantification (CRQ) with Kevin Milne
<p>In this episode of the Vertali Podcast, host Ed Nell is joined by Kev Milne, Cyber Threat Manager at NatWest Group who also runs a mainframe pen testing course and is writing a book on Mainframe Hacking. Kev gives us a deep dive into cyber risk quantification, red teaming, and the growing need to include mainframes in modern cyber security testing. Kev draws on more than 30 years of experience in cyber security, from penetration testing and risk management to cyber threat intelligence, to explain why organizations need to move beyond vague risk labels and toward evidence-based, business-focused conversations about cyber threats.</p><br><p><strong>Key Takeaways</strong></p><p>Cyber Risk Quantification Makes Risk More Actionable: Kev explains that cyber risk quantification helps turn cyber security from a vague discussion of “high” or “medium” risk into something more useful by identifying likely threat actors, attack methods, technical outcomes, and potential financial consequences. This makes it easier for leaders to understand what is really at stake.</p><br><p>Evidence Matters More Than Assumptions: Rather than relying on gut feel or subjective scoring, Kev emphasizes using penetration test reports, red team findings, audit reports, vulnerability scans, and risk registers to measure actual exposure. That evidence-based approach helps validate whether security controls are truly working.</p><br><p>Red Teaming Goes Beyond Traditional Penetration Testing: Kev describes red teaming as broader and more realistic than a standard penetration test. It can include physical security, social engineering, open-source intelligence, phishing, and cross-network movement to simulate how real attackers behave, rather than just testing a narrow technical scope.</p><br><p>Mainframes Should Not Be Left Out: One of the episode’s core messages is that mainframes are still often excluded from red teaming and cyber risk quantification because many security teams do not understand them, while mainframe teams may be wary of offensive testing. Kev argues that this creates a dangerous blind spot, especially since attackers are unlikely to ignore systems that hold critical business data and processing power.</p><br><p>AI Is Accelerating the Threat Landscape: Kev highlights how AI is making phishing and cyber attacks faster, easier, and more effective. He points to a rise in successful phishing and faster lateral movement within networks as signs that organizations need to improve testing, monitoring, and communication now rather than later.</p><br><p><strong>Best Moments</strong></p><p>“Cyber risk quantification is really about making cyber risk useful.”</p><br><p>“When you start to see, here is a risk, here is who could attack it, here’s how they would do it, and this is the outcome technically and the outcome financially, that is where cyber risk quantification becomes really pretty useful.”</p><br><p>“Red teaming engagement is more about see what you can do, see if you can get in.”</p><br><p>“The mainframe is doing all the processing… the crown jewels.”</p><br><p>“If we don’t test, there’s something that we don’t know that they will know.”</p><br><p>“Make sure that the techies and the business side talk to each other.”</p><br><p><strong>About Vertali</strong></p><p>Vertali is a leading cyber security company specialising in IBM® mainframe infrastructure.

MainTegrity: The days of static cybersecurity reporting are over
<p>In this episode of the Vertali Podcast, Ed Nell talks with MainTegrity’s Al Saurette about why static cyber reporting no longer works for modern mainframe security and what a real-time, human-in-the-loop defense looks like. They dig into ransomware’s business model, why milliseconds matter, how to spot reconnaissance early, and the practical mechanics of “freeze first, verify, then resume” so attacks are contained before damage spreads.</p><br><p><strong>Key Takeaways</strong></p><p>Static reports can’t keep up: Cybersecurity is a real-time problem; waiting for daily violation printouts assumes humans can react fast enough, which they simply can’t. Action has to begin before a person can even read a dashboard.</p><br><p>Milliseconds matter: Modern hardware can encrypt huge volumes of data in fractions of a second. Detection and containment must happen in milliseconds, not minutes or hours.</p><br><p>Freeze first, then decide: When anomalies appear, pause the activity immediately. If a human later validates it, resume from the exact point without disruption; if not, cancel and remediate.</p><br><p>Spot recon early: Look for reconnaissance signatures, unsanctioned file changes, privilege probing, or sudden spikes in data access, especially from “trusted” network partners where an upstream environment may be compromised.</p><br><p>AI is a force multiplier, not an autopilot: AI can help analyze rich real-time telemetry and accelerate triage, but final authority and recovery decisions should remain with humans, especially for restore actions.</p><br><p>Recovery needs root-cause clarity: Restoring data alone can re-ignite malware. You must identify where malicious changes were introduced, remove them, and restore systems to a trusted state—otherwise you risk a second outage.</p><br><p><strong>Best Moments</strong></p><p>“Cybersecurity these days is a real-time event… the criminals are attached to your system more or less when you start.”</p><br><p>“The time frames are milliseconds… who can possibly react in a second?”</p><br><p>“Stop the suspicious activity, then let people decide whether to continue or kill it.”</p><br><p>“There was a US case where the outage went on for nine days… the estimated cost to recovery is $3 billion.”</p><br><p><strong>About Vertali</strong></p><p>Vertali is a leading cyber security company specialising in IBM® mainframe infrastructure. With deep expertise, innovative software, and trusted resources, Vertali supports organisations across the UK and globally, particularly in finance, retail, utilities, and government sectors.</p><br><p>100% focused on mainframe systems, Vertali helps organizations secure and optimize their operations.

Broadcom: Bracing For The Quantum Shift
<p>In this episode of the Vertali Podcast, Broadcom’s Michael Jordan (Distinguished Engineer, Cybersecurity & Compliance) and Jessica Daugherty (Senior Product Manager, Security & Compliance) about “Y2Q”, the day quantum computers can break today’s cryptography, and what enterprises must do now to prepare. They unpack how RSA falls to Shor’s algorithm, why “harvest now, decrypt later” makes quantum risk urgent today, where NIST’s post-quantum standards stand, and practical first steps like building a cryptographic inventory and a migration plan. They also touch on IBM Z16/Z17 “quantum-safe” capabilities and lessons from Y2K for a whole-of-industry response.</p><br><p><strong>Key Takeaways</strong></p><p>What “Y2Q” really means: It’s the point at which a cryptographically relevant quantum computer can break widely used public-key algorithms; the core reason is mathematical (e.g., factoring the RSA modulus reveals the private key).</p><br><p>Shor’s algorithm changes the game: Classical computers make factoring infeasible at today’s key sizes; quantum computers running Shor’s algorithm reduce the problem to hours, undermining RSA and elliptic-curve schemes.</p><br><p>Standards are arriving: NIST has selected and published post-quantum algorithms (FIPS 203/204/205), with IETF TLS updates in draft and expected to finalize on a near-term horizon.</p><br><p>Global roadmaps differ: The US/UK are working toward broad migration by 2035, while Germany and Australia are targeting around 2030, all aiming to pre-empt sudden quantum breakthroughs.</p><br><p>Mainframe head start: IBM Z16 introduced quantum-safe system validation and access to NIST-backed algorithms via Crypto Express HSMs (also on Z17), positioning mainframe shops to adopt earlier.</p><br><p><strong>Best Moments</strong></p><p>“Imagine the day when all the crypto that we rely on stops working… That day is coming, and it’s called Y2Q.”</p><br><p>“If you could factor out those two large prime numbers… you could compute the private key and thus you’ve broken RSA.”</p><br><p>“Our mainframes are already considered quantum safe… Z16 was introduced as the world’s first quantum-safe system.”</p><br><p>“The first task… is to discover all of the cryptographic usages within their system and build a cryptographic inventory.”</p><br><p><strong>About Vertali</strong></p><p>Vertali is a leading cyber security company specialising in IBM® mainframe infrastructure.
