3221: IGEL on Securing the Edge with Zero Trust and Preventative Models

What if the next major leap in cybersecurity isn't a new tool but a smarter way to think about the edge? In this special episode recorded live at IGEL Now & Next 2025 in Miami, I sit down with John Walsh, Field CTO for Critical Sectors at IGEL, to unpack the changing face of endpoint security, the rise of zero trust, and the role of AI in shaping both threats and defenses.

John brings a career’s worth of insight across aerospace, defense, and high-assurance systems to a conversation that covers the shifting threat landscape and how IGEL’s preventative security model is helping organizations reduce complexity while strengthening security. He explores the vulnerabilities introduced by hybrid work, BYOD environments, and the increasing reliance on AI models that interact with an enterprise’s most sensitive data.

We dive into how zero trust is evolving from a marketing buzzword into a practical framework built on collaboration, unified management, and strong policy enforcement at the endpoint. John breaks down why zero trust isn’t a single product or checklist but an ecosystem of technologies and partnerships that need to operate together—securely and seamlessly.

He also explains why endpoint security still matters, how most attacks still originate at the edge, and why IGEL’s immutable operating system is designed to shut down threats before they even begin. As AI-powered attacks accelerate, John also discusses the importance of reducing noise for incident response teams and the potential for AI to eventually move from defense to pre-emptive strike.

If you’re leading cybersecurity in government, finance, manufacturing, or any sector with critical infrastructure, this conversation will give you a clearer view of where endpoint protection fits into a secure, cloud-connected, AI-augmented world. What are you doing today to make sure your organization’s edge is ready for tomorrow?
