How do you keep your startup secure?

That’s the big question we explored at TC Sessions: Enterprise earlier this month. No matter the size, every startup is an enterprise. Every startup will grow in size as it builds out. But as a company expands, that rapid growth can lead to a distraction from the foundational principle of any modern company — keeping it secure.

Security isn’t just a buzzword. As some of the largest companies in Silicon Valley have shown, security can be difficult. From storing passwords in plaintext to data breaches galore, how can startups learn from some of the biggest security lapses in the tech industry’s history?

Our panel consisted of three of the brightest minds in enterprise security: Wendy Nather, head of advisory CISOs at Duo Security, is an enterprise security expert; Martin Casado, general partner at Andreessen Horowitz, is a security and enterprise startup investor; and Emily Heath, United’s chief information security officer, oversees the security operations of the largest U.S. airlines.

This is what advice they had.
