#032 | S4 | In The Chair | Default Denied

Published on Monday 18th Nov, 2024

In an earlier episode, we explored Marcus Ranum’s Six Dumbest Ideas in Cybersecurity and uncovered why Enumerating Badness just doesn’t cut it. Yet even now, application-level whitelisting remains messy. In this episode, Helen puts Seamus Lennon, VP of European Operations at ThreatLocker, in the hot seat to dig into the Default Deny approach—a principle at the heart of ThreatLocker’s independent product offering. Why is blocking everything by default such a powerful concept, and why does it remain relevant in today’s security landscape? Seamus shares insights, stories, and practical thoughts on navigating the challenges of whitelisting, tackling threats, and rethinking what secure really means. Is Default Deny too restrictive, or is it the secret to cutting through the chaos?
