The PowerShell Podcast

Encore presentation: Lessons in Leadership from PowerShell Pioneers Jeffrey Snover and Don Jones 

In this encore presentation of the PowerShell Podcast from April 28, 2025, we sit down with two legends of the PowerShell world: Jeffrey Snover, the inventor of PowerShell, and Don Jones, bestselling author, teacher, and longtime PowerShell community builder. Recorded live at the PowerShell + DevOps Global Summit, this conversation is packed with personal insights, impactful moments, and the kind of storytelling that only Snover and Jones can deliver.  

 Key topics in this episode include:  

 The origin stories of PowerShell and how Jeffrey and Don’s paths crossed at a pivotal moment.  

The evolution of PowerShell as a scripting language, community, and ecosystem.  

The importance of storytelling in tech, from teaching to team-building to leadership.  

The shift from individual contributor to leader and how both hosts navigated that path with intention.  

The power of community: real stories from users whose lives were changed by learning PowerShell.  

Career advice for the next generation of IT professionals and community contributors.  

Along the way, we hear hilarious stories from the early days of PowerShell development, honest reflections on growth and failure, and powerful reminders that vulnerability, repetition, and kindness are core to success in any career. Whether you're new to PowerShell or a long-time community member, this episode is a true masterclass in leadership, learning, and legacy.

Andrew sits down with Leo D'Arcy, cloud solutions architect and PSConfEU speaker, to talk certificates, PKI infrastructure, and why so many organizations get it so spectacularly wrong. Leo shares how a decade of consulting work in remote access solutions pulled him into the world of Active Directory Certificate Services whether he liked it or not, and how that hands-on experience turned into conference talks and a genuine specialty. The conversation covers the difference between self-signed certs and proper CA infrastructure, why code signing deserves more attention than it gets, and how integrating signing into a CI/CD pipeline is less painful than it sounds. They also get into the "developer-ization" of IT, the underrated value of consulting experience for career growth, and why communicating across teams is just as important as knowing your PowerShell.
 
Key Takeaways:

Code signing through a CI/CD pipeline is a practical, scalable alternative to constrained language mode. By adding a signing step to your build process, you get cryptographic proof that scripts haven't been tampered with, without giving up flexibility in what you can run.

Self-signed certificates are essentially the same as having no certificate at all. A proper PKI means having a chain of trust, a policy behind how certs are issued, and infrastructure that your organization actually manages and maintains.

Technical depth only gets you so far. The people who advance in IT are the ones who can talk networking with network engineers, infrastructure with server teams, and business outcomes with leadership. Soft skills aren't a bonus, they're a multiplier.

In this episode, Andrew chats with Adriano Carollo at PSConfEU about community, PowerShell Universal, AI, and what happens when you stop lurking and start talking to people. Adriano shares how PowerShell helped him grow from sysadmin into web apps, automation, and open source-style contribution, while Andrew reflects on learning, AI, and why enthusiasm still matters.  

Key Takeaways: 
· Community accelerates growth. Adriano came to PSConfEU after hearing Andrew encourage listeners to engage, and the payoff was immediate. 
· PowerShell Universal can open unexpected doors. Adriano describes using it daily to learn web development concepts like JavaScript, HTML, and React through PowerShell. 
· AI is most useful when it supports learning instead of replacing it. Both Andrew and Adriano talk about using AI for research, syntax help, documentation, and personal workflows while still valuing hands-on problem solving.

Recorded live at PSConfEU 2026, Andrew sits down with returning guest Miriam Wiesner, Senior Security Researcher at Microsoft, for a wide-ranging conversation on PowerShell security, cookie-based attacks, and the evolving threat landscape. Miriam walks through her two conference talks — one on Microsoft Teams session cookie hijacking (a follow-up to her 2025 Entra ID cookie talk, complete with Cookie Monster branding and actual handcuffs), and a joint session with Stéphane van Gulick on using Microsoft Defender's Live Response feature for incident investigation. The conversation also covers the current state of PowerShell security, why sophisticated attackers are moving away from PowerShell, and why defenders who haven't enabled script block logging and AMSI are leaving easy wins on the table. On top of the technical deep dive, Miriam and Andrew get into the human side of the conference community — nerves before presenting, imposter syndrome, and why showing up is already half the battle.

Key Takeaways:

Cookie-based identity attacks are an active and growing threat. Microsoft Teams, SharePoint, and OneDrive share session cookies, meaning a single cookie theft can give an attacker broad access across your organization's collaboration tools — no re-authentication required.

Sophisticated threat actors are moving away from PowerShell specifically because its security features work. Script block logging, AMSI, and Constrained Language Mode make PowerShell activity highly visible and detectable. If your org hasn't enabled these, you're handing attackers an easy path.

Visibility beats prevention. You can't prevent what you can't see. Detection through proper logging is not a consolation prize — it's a core security strategy, and Microsoft Defender's Live Response feature gives teams a powerful way to investigate isolated endpoints without needing RDP or PowerShell remoting enabled.

Frank Lesniak joins Andrew Pla for a wide-ranging conversation that covers Frank's newly minted Microsoft MVP status, his journey through PowerShell, and what it looks like to build a real presence in the tech community. Frank talks through the pipeline struggles that tripped him up early on, how his VB Script and object-oriented background made the shift to PowerShell's object model feel disorienting, and how AI has quietly changed the way he approaches scripting today. The conversation takes a thoughtful turn as Andrew and Frank dig into impostor syndrome, the value of conference speaking, and how showing up consistently in the community compounds into a career. Frank also shares an update on DuPage Animal Friends, the nonprofit he serves, which supports one of the country's highest-performing open-admission animal shelters.

Key Takeaways:

The PowerShell pipeline is one of the most commonly cited stumbling blocks for newcomers, especially those coming from text-based scripting backgrounds. Learning to visualize what your objects look like at each stage of the pipeline, using tools like Get-Member, is a skill that pays dividends long term.

Showing up at conferences and user groups, even when you feel underprepared, is how you build the reps that eventually make it feel natural. Frank's consulting background gave him a head start on presentation skills, and he's clear that no one is born polished.

Community involvement and career growth are more connected than they might look from the outside. Engaging with people on GitHub, at events, and through open source creates a feedback loop that builds confidence and opens doors.

Guest Bio:
Frank Lesniak returns to The PowerShell Podcast, this time as a Microsoft MVP (Microsoft Azure, PowerShell). Frank is a Sr. Cybersecurity & Enterprise Technology Architect at West Monroe, where PowerShell runs through client work on corporate M&A: carve-outs, tenant-to-tenant migrations, identity consolidation, endpoint moves, and security posture improvement across Microsoft 365, Azure, Entra ID, Active Directory, Intune, Defender, and Windows.

Beyond consulting, Frank speaks at technical conferences, mentors first-time speakers, and publishes open-source PowerShell standards and tooling, including PSStyleGuide, GloryRole, and PSConnMon. His public work threads least-privilege identity, cloud role mining, cross-platform observability, and high-quality AI-assisted development through standards, automated tests, and automated code quality reviews.
