"I've had the honour of working with some of the most disruptive technologies and security firms during my career, but I've never been more excited about the potential of a company like Aqua. Cloud native security is the future of cybersecurity, and Aqua is the future of cloud native," said Sexton.
"As the cloud native security market explodes, Aqua Security is clearly at the forefront.
"Many vendors just provide visibility or compliance, but preventing and protecting from a breach in production is the holy grail. Aqua is the only player with the technology to do both, and I'm thrilled to join them for this journey."
