Inside the Network

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.
