Inside the Network

Our guest in this episode is Rob Lee, co-founder and CEO of Dragos. Two weeks ago, Accenture agreed to acquire a majority stake in Dragos as part of the massive, over $4 billion transaction that also included the acquisitions of runZero and NetRise. As luck would have it, we recorded this conversation just a few weeks before the announcement. Massive congratulations to Rob and to the entire teams of Dragos, runZero, and NetRise!
​
When Rob started Dragos, most investors didn't believe critical infrastructure security was a venture-scale opportunity. Despite getting more than 100 rejections from investors, Rob stayed committed to his mission. Today, Dragos protects critical infrastructure around the world and has become one of the defining companies in industrial cybersecurity.
​
This episode isn't simply about building a unicorn or leading a company to a massive exit. It's about building a company around a mission. Rob explains why Dragos exists to "safeguard civilization," why protecting critical infrastructure is fundamentally different from protecting enterprise IT, and why cybersecurity in operational technology is ultimately a public safety problem, not just a business problem.
​
Throughout the conversation, Rob shares candid lessons from building Dragos over the past ten years. We discuss choosing investors, surviving VC rejections, scaling from three founders to more than 600 employees, building a founder-led culture, making difficult executive hiring decisions, expanding internationally, and why Rob believes founders should optimize for long-term mission rather than short-term valuation.
​
We also dive deep into the future of critical infrastructure security. Rob explains how AI is changing operational technology, why cyber warfare is increasingly targeting civilian infrastructure, what keeps him awake at night as geopolitical tensions continue to rise, and why he believes the next generation of cybersecurity founders should pay far more attention to industrial systems than they do today.
​
It’s a fascinating story about a founder who decided to build a mission-driven company instead of trying to optimize for an exit or the next funding round. By doing that, not only has he succeeded in building something lasting, but he also achieved a massive financial outcome.

Our guest in this episode is Mike Fey, co-founder and CEO of Island, one of the fastest-growing cybersecurity companies. Founded just five years ago, Island has raised over $700 million in funding, crossed $5 billion valuation, and helped create an entirely new category: the Enterprise Browser.

Mike has scaled massive cybersecurity businesses. Over the course of his career, he has served as CTO of Intel Security and President of both Blue Coat and Symantec. Mike played a key role in some of the largest transactions in cybersecurity history, including Intel's $7.7 billion acquisition of McAfee, Symantec's $4.7 billion acquisition of Blue Coat, and Broadcom's $10.7 billion acquisition of Symantec's enterprise business.

After decades of leading some of the industry's largest security companies, Mike could have easily become an investor, advisor, or board member. Instead, he decided to start over from scratch. Together with co-founder Dan Amiga, he set out to challenge one of the most entrenched pieces of enterprise software: the browser. At first glance, building a browser company sounded like a terrible startup idea: enterprises already had Chrome, Edge, Safari, and countless security products protecting them. Yet Mike and the Island team believed that the browser was evolving into the primary workspace for modern employees and that whoever controlled the browser could fundamentally rethink security, productivity, and the future of work.

On Inside the Network, Mike shares the story behind Island's creation, why he initially rejected the idea before becoming convinced it could become a generational company, and how the team navigated the challenge of convincing enterprises to replace one of the most widely used pieces of software in the world.

We discuss category creation, the Innovator's Dilemma, building go-to-market organizations from scratch, fundraising strategy, and the lessons Mike learned from scaling businesses through more than $20 billion worth of acquisitions. He explains why founders often underestimate sales and go-to-market execution, how startups can use incumbents' strengths against them, and why market timing matters more than many entrepreneurs realize. We also dive into the impact of AI on enterprise software and cybersecurity, how AI is reshaping the role of the browser, and why Mike believes the browser will become the front door through which enterprises adopt and operationalize AI.

This episode of Inside the Network is unique because it is our very first show recorded live on the RSAC 2026 stage in front of security leaders, startup founders, and identity experts. For this episode, we had the privilege of sitting down with one of the most accomplished founders in cybersecurity, founder and CEO of SailPoint, Mark McClain.

Cybersecurity is not an easy market to take a company public, and only the most successful founders have the opportunity to take a company public just once. Mark on the other hand has taken the same company public twice. He created the identity governance category from scratch, grew the company into a global identity security leader with more than $1 billion in ARR, over 3,000 employees, and customers across nearly half of the Fortune 500, took it public in 2017, private again with Thoma Bravo in a multi-billion-dollar transaction, and then back to the public markets in 2025.

This episode explores one of the biggest questions in cybersecurity today: how do incumbents survive and win in the age of AI? 
Mark shares how large cybersecurity companies think about innovation, disruption, and adaptation in a world that’s changing faster than ever before. We discuss whether incumbents can turn scale, distribution, and customer trust into long-term advantages, or whether AI creates the perfect opening for a new generation of startups to challenge established leaders. 

Throughout the conversation, Mark reflects on the evolution of identity security from compliance tooling into one of the most critical security control planes in the enterprise. We dive into the rise of non-human and agentic identities, why traditional governance models are breaking under the speed of AI, and how companies like SailPoint are adapting to a world where identities can be ephemeral, autonomous, and operating at machine speed.
We also talk about building startups in Austin versus Silicon Valley, lessons from taking the same company public twice, the realities of operating as both a public-company CEO and a founder, and what early-stage founders continue to underestimate about enterprise cybersecurity markets. 
In closing, Mark shares candid advice for founders building in cybersecurity today: where startups still have a real edge, what markets are ripe for disruption, and why listening to customers remains the ultimate competitive advantage.

In this episode of Inside the Network, we sit down with Christina Cacioppo, Co-Founder and CEO of Vanta, the company that defined what is now known as trust management. What began as a scrappy effort to make SOC 2 less painful, has grown into one of the most important platforms in security and compliance. 

Christina’s path into cybersecurity was anything but conventional. She started her career in venture capital, and then worked as a product manager at Dropbox, where a frustrating encounter with compliance requirements revealed just how broken security audits were for fast-moving product teams. In our conversation, Christina shares how that painful Dropbox experience led to Vanta, why the company’s earliest product was essentially a spreadsheet rather than software, and how doing things manually helped her team find product-market fit faster. She talks about her process of ideation before landing on the idea, the decision to let word of mouth drive the business forward, what Vanta got out of joining Y Combinator, and why it intentionally avoided raising large rounds of venture capital in the early years. 

Christina offers a refreshingly honest look at leadership and scale. She discusses the hard lessons of hiring executives, the importance of defining company principles through real mistakes rather than corporate platitudes, and the challenge of moving upmarket without abandoning the startups that made Vanta successful in the first place. Christina explains how competition changed her perspective on storytelling, why founders cannot let others define their narrative, and how much of company-building is really about learning on real people in real time. This episode is full of hard-earned lessons on conviction, clarity, and the long game of building a multi-billion-dollar company.

In this episode of Inside the Network, we sit down with Sanjay Beri, Founder and CEO of Netskope, a company that sits at the intersection of AI, data security, and global edge networking. Over thirteen years, Sanjay scaled Netskope to 4,000+ customers (including 30% of the Fortune 100), 3,000+ employees across 30 countries, and ultimately took the company public in September 2025 in one of the year’s standout cybersecurity IPOs.

Sanjay’s journey is a masterclass in playing the long game. From growing up in Canada selling door-to-door with his mom, where he learned grit and resilience, to working at Microsoft during the early internet era, to becoming one of Juniper’s youngest VPs running a large business, Sanjay built the rare blend of product, go-to-market, and leadership muscle it takes to build at scale.

We talk about the origins of Netskope, why it was never “just a CASB,” how Sanjay recruited world-class early engineers and built a high-trust culture, and what product-market fit looked like in the first chapter of the company. He also breaks down some of Netskope’s biggest bets, including building its own edge cloud instead of relying on public cloud networks, and launching AI Labs years before today’s GenAI wave.

Whether you’re building a cyber startup, scaling into the enterprise, or studying what it takes to go from zero to IPO, this episode is packed with hard-earned lessons on conviction, the importance of building a winning culture, and endurance.
