At CES in January, NVIDIA, AMD, Siemens and others spun elaborate tales of a world suffused with AI: AI in the cloud, AI at the desktop, AI in the factory, AI underneath enterprise software and as the UI for enterprise software and agentically accomplishing anything and everything in a world of embodied, physical AI. Johna... Read more »
PP100: Building and Securing AI Agents – A Case Study
Kyler Middleton, a software developer in the healthcare sector, builds and supports AI bots and AI agents that are now widely used inside the company where she works. Today on Packet Protector, Kyler stops by to talk about how and why she built these tools, how she (and her organization) address the risks these tools... Read more »N4N050: Multicast Fundamentals
Today’s learning adventure is an overview of multicast. Ethan and Holly have invited a guest to share his multicast expertise: Lenny Giuliano, Sr. Distinguished Systems Engineer at HPE Juniper Networks. Lenny guides them through multicast principles and shares examples of where and how it’s used in live networks. He also explains how the OSPF routing... Read more »HW072: Wireless-Adjacent Products from Digi International
Digi International has a whole lot of things that aren’t exactly in the Wi-Fi space, but are close enough to be of interest to WLAN engineers. Joining us today to talk about Digi International’s wireless tech, and what it means for wireless LAN pros, is Bob Blumenscheid. Bob discusses Digi’s offerings, including their XBee modules,...

Today we’re going to learn about the care and feeding of a three-headed dog named Kerberos. Developed at MIT and released in 1989, Kerberos is a free, open source authentication protocol that uses cryptographic keys to protect identity data as it crosses a network. Today, Kerberos is the backbone of Windows authentication. We’ll dive into... Read more »TNO056: A Culture of Precise Work: Data Center NetOps
With the continued growth of data centers for clouds, neoclouds (especially AI model training), for carriers, and for the enterprise, it’s important to discuss data center network operations and issues. Scott is joined by Dr. Peter Welcher, a consultant, blogger, and Tech Field contributor. Together, they dive into how latency and the rise of AI... Read more »TCG069: Viral Predictions, Waterfall’s Comeback, and the SaaSpocalypse
William and Eyvonne tackle the biggest AI stories of early 2026. They dissect Matt Schumer’s viral “Something Big is Happening” essay – agreeing professionals need to skill up now while pushing back on the doomsday framing with real-world examples from engineering disciplines. The conversation takes a fascinating turn as Eyvonne draws a parallel between AI-assisted... Read more »NAN114: Demystifying Automation Tools, Processes, and Culture Gates
Eric sits down with David Henderson, Principal Architect for NetDevOps at Presidio, to discuss the practical journey for network engineers transitioning from manual CLI operations to scalable NetDevOps and automation. They discuss how traditional networking knowledge and certifications are foundational, and suggest essential tools and habits for beginning your automation journey. David also shares a... Read more »PP098: What Goes On Inside a Firewall?
On today’s show, we pop the lid off of a firewall (figuratively speaking) to understand what’s inside. We talk about how a packet moves through various packet-processing elements inside a firewall, how header analysis and de-encapsulation work, which hardware component has the biggest impact on performance, why stateful inspection still matters in an age of... Read more »HS125: How to Choose an IT Hiring Service
Every employer knows to conduct background checks. However, conducting background checks on IT professionals requires an extra layer of verification, given the privileged access they typically have to IT systems and tools. Moreover, in this AI era, background checks need to be deeper and more effective than before–in the past we didn’t need to verify... Read more »
N4N049: Understanding Firewalls
Today, Ethan and Holly provide an overview of firewalls. While cybersecurity is a separate discipline from network engineering, much of what happens in cybersecurity is interesting at the packet level, so there’s a good deal of overlap. It’s likely that as a network engineer, you’ll be managing, or at least dealing with, firewalls in your... Read more »HW071: New iOS Tools for WLAN Pi
Adrian Granados joins Keith Parsons to discuss new iOS tools available for the WLAN Pi. These new tools extend a professional’s ability to run Wi-Fi scanning and analysis apps such a Wi-Fi Explorer Pi and Airtool Pi on iOS devices such as iPhones and iPads. Along with the small, portable WLAN Pi itself, these apps... Read more »PP097: How and Why to Turn the Browser into a Universal Security Agent (Sponsored)
With the rise of cloud services and SaaS, the browser has become a primary productivity tool. It’s also a primary vector for malware, phishing, identity theft, data leaks, and other risks. On today’s sponsored episode with Palo Alto Networks, we dive into browser security. We discuss risks to the browser and how they differ from... Read more »TNO055: Testing as a Service for Telco Network Services
Scott talks with Mark Gebert from Verizon about something that sits at the heart of every reliable enterprise network: testing. Automation is moving fast in the telco world, but automation without testing is just an accident waiting to happen. They unpack what makes enterprise service provisioning so complex—multi-vendor networks, optical and IP gear, security functions,...
