Expanse (originally founded as Qadium) was a cybersecurity company specializing in internet attack surface management, continuously discovering and monitoring an organization's internet-connected assets to find exposures and unmanaged risk. The company was backed by IVP, Susa Ventures, and Y Combinator, and was acquired by Palo Alto Networks in 2020. Its technology now ships as Cortex Xpanse, part of the Palo Alto Networks Cortex platform, and the expanse.co domain 301-redirects to the Cortex Xpanse product page.
