Documented cause

Twistlock built a container and cloud-native security platform, founded in 2015 by Ben Bernstein and Dima Stopel. The startup raised $63M including a $33M Series C in 2018 and was growing rapidly. Palo Alto Networks acquired Twistlock in June 2019 for $410M as part of a $670M dual acquisition alongside PureSec. Despite the premium exit, the Twistlock brand was retired and folded into Prisma Cloud, eliminating independent product development within 18 months.

Lesson

“Cloud-native security niches collapse fast into platform plays; sell early or build a moat in data.”
