Expanse (formerly Qadium) is a US cybersecurity company that built an internet collection and attribution platform to continuously discover, monitor, and map an organization's global internet-exposed and untracked assets - the external attack surface. Founded in 2012 in San Francisco by Tim Junio, Matt Kraning, Shaun Maguire and Joseph Meyerowitz, the company emerged from work the founders did at DARPA and built a customer base spanning Fortune 500 enterprises (CVS/Aetna, PayPal, Capital One, Allergan, Hudson's Bay) and US federal agencies including the Departments of Defense, Energy, and State, as well as the US Army, Navy and Air Force. Expanse was acquired by Palo Alto Networks in December 2020 for approximately $800M (roughly $670M cash and stock plus ~$130M in replacement equity awards) and its technology became the foundation of Cortex Xpanse, Palo Alto Networks' attack surface management product line.
