In this episode of Inside the Network, we sit down with Joe Levy, CEO of Sophos, a 40-year-old cybersecurity company that has quietly become one of the most important global players, serving over 600,000 organizations and generating over $1 billion in revenue.

Throughout his career, Joe has operated with a founder's mindset: thinking in bets, building great teams, spotting technical and market inflection points, and executing with long-term discipline. A great example is Sophos’ recent $800+ million acquisition of Dell Secureworks, adding over 1,000 new team members and significantly expanding Sophos’ managed detection and response and extended detection and response (MDR/XDR) capabilities.

Today’s session is an exciting masterclass on how a technically astute CEO navigates demanding customers, engages positively with Private Equity giants like Thoma Bravo, and partners with MSPs globally, while building a culture of "vulnerability-based trust”. One of the most insightful statistics Joe and his team at Sophos have highlighted is that while there are over 350 million businesses worldwide, fewer than 1 in 10,000 have a CISO.

This episode is packed with practical lessons on founder transitions, managing through personal health crises, and building resilient security organizations. For any cybersecurity founder thinking about the long game, Joe’s story is one you’ll want to hear.

As mentioned in the episode, Joe shared a curated list of books he’s been collecting over the years for his daughter, a shelf he calls “my daughter’s bookshelf.” These aren’t just bedtime stories; they’re books that have shaped Joe’s thinking about the world, passed along with personal inscriptions to provide context and reflection. Some were even introduced by his wife, Tracie, and read together as a family, like the James Herriot series, which took nearly a year to complete and left a lasting impression. This isn’t meant to be a definitive reading list - many classics, business books, and philosophical staples are intentionally left out. But it offers a deeply personal window into the stories that have mattered most to Joe as a parent, leader, and lifelong learner. He also shared a second resource: a living document of quotes, mental models, and hard-won career lessons, many of which have shaped his leadership journey and are referenced throughout the episode. You can explore both below.

In this RSAC special episode of Inside the Network, we sit down not with one, but two remarkable guests from the center of the cybersecurity world.

First, we’re joined by Andy Cao, COO of ProjectDiscovery, a company focused on open-source vulnerability management tools, which won the "Most Innovative Startup" award at the RSA Conference 2025 Innovation Sandbox. Andy shares how ProjectDiscovery is reimagining vulnerability management in an AI-driven world, what set their pitch apart in the Innovation Sandbox, and how their attacker-first mindset is reshaping how security teams discover and fix real-world exposures. With over 1 million users and thousands of Nuclei templates, ProjectDiscovery is aiming to make vulnerability detection radically faster, smarter, and more accessible.

Then, we shift gears to talk with Dr. Hugh Thompson, Executive Chairman and Program Committee Chair of RSAC. A world-renowned security expert and longtime steward of the conference, Hugh takes us behind the curtain of what it takes to run the world’s largest cybersecurity gathering, including the bold moves that shaped this year’s Innovation Sandbox, the evolution of the RSAC brand, and the future of security thought leadership in the age of AI. And most intriguingly, Hugh gives us an exclusive answer to the question everyone’s been asking - is RSAC 2026 moving to Las Vegas?

To close, Mahendra, Sid, and Ross share their favorite moments from the show floor - the trends that caught their attention, the buzz from founders and investors, and yes, even a surprise guest spotted at the expo (spoiler: it’s not a unicorn, but maybe the GOAT?).

Whether you made it to RSAC this year or followed from afar, this episode brings you fresh insights from both the main stage and the show floor.

In this episode of Inside the Network, we sit down with Dug Song, the legendary co-founder and former CEO of Duo Security. Dug's journey is nothing short of iconic—he turned a side project into a cybersecurity powerhouse with over 50,000 customers and a $2.35 billion exit to Cisco. In a world obsessed with unicorn status and funding hype, Dug stands out as a founder who stayed grounded in values, culture, and customer empathy.

We explore Dug’s early years—from doing data entry in his father’s liquor store in West Baltimore to cutting his teeth at Arbor Networks, leaving security, and coming back to change how security is delivered. Dug was also part of the hacker collective w00w00, alongside future tech luminaries like Jan Koum (WhatsApp) and Shawn Fanning (Napster), where he honed the ethos of solving hard problems and building in community. These experiences laid the foundation for Duo, which Dug and co-founder Jon Oberheide started not with a grand business plan but a desire to democratize security and make strong authentication simple and usable for all organizations—not just the Fortune 500.

This conversation is packed with actionable lessons for founders: how to build a billion-dollar business with capital efficiency and discipline; how to prioritize user experience in security, not just infrastructure; and how to lead with integrity and build a “learning organization” that continuously improves across every function—engineering, sales, marketing, and customer success. Dug also gives an inside look at the decision to sell Duo to Cisco versus going public and what that choice meant for the company, team, and customers.

We then dive into Dug’s post-Duo chapter, where he and his wife Linh are reshaping philanthropy and backing the next generation of founders in Michigan, Detroit, and beyond. From punk rock to planetary-scale startups, Dug brings a rare mix of grit, humility, and wisdom, making this episode a must-listen for any entrepreneur.
