How Delta Airlines Reimagined Cybersecurity Awareness for 100,000+ Employees, with CISO Deborah Wheeler

What if security awareness training was something your employees looked forward to? In this episode of Vigilance, Delta Airlines CISO Deborah Wheeler joins Pam Brodt to share how she turned one of the most overlooked areas of cybersecurity—employee awareness—into a cultural movement inside a global enterprise. With a workforce of over 100,000, Deborah had to ditch fear-based training, design for a diverse range of roles (including flight crews), and build a program that empowers people at home and at work. What she and her team built is remarkable: * A gamified phishing derby with 50,000+ entries and company-wide excitement * Security training that starts with personal safety, not corporate policy * Tailored, role-specific delivery formats to meet people where they are * A measurable drop in phishing click-through rates and a surge in reporting * Awareness campaigns run by a team of just three people Whether you’re a CISO, awareness program owner, or enterprise leader—this conversation is a masterclass in human-first security strategy.🎧 Watch the full episode to learn: * How to scale employee engagement across a massive enterprise * Why storytelling and incentives work better than fear * How to measure behavior change beyond compliance checkboxes * Why your awareness team shouldn’t come from cybersecurity

The Hidden Threat Inside Every Enterprise: What CISOs Are Missing in the Software Supply Chain, with Koi’s Amit Assaraf

CISOs, are you watching the front door while attackers slip in through the side? In this episode of Vigilance, Pam Brodt sits down with Amit Assaraf, co-founder and CEO of Koi, to expose a massive blind spot in modern enterprise security: the unmonitored sprawl of extensions, registries, app stores, and marketplaces powering your software supply chain. Amit recounts how a simple experiment—uploading a lookalike VS Code extension—landed them inside Fortune 500 environments in under 7 days, undetected. The same path is being used by nation-state actors like Lazarus Group to breach global enterprises. We cover: * Why auto-updates and ownership transfers are critical (and overlooked) attack vectors * How trusted platforms like Chrome, NPM, PyPi, and Hugging Face are being exploited * Why EDRs and AppSec tools fail to detect these threats * How Koi is using AI-driven risk engines to monitor and secure 30+ marketplaces—without deploying a single new agent If you’re a security leader balancing productivity and protection, this conversation will change how you think about supply chain risk. 🔒 Don’t miss this one—it’s the conversation every enterprise CISO needs to hear.
