Skybox Security, a once high-flying startup that raised north of $300 million, has abruptly shut down, laying off its entire workforce in Israel and the United States.
The shutdown follows the immediate sale of Skybox Security’s business and technology assets to rival Israeli cybersecurity firm Tufin.
According to reports out of Skybox Security’s Israeli headquarters, chief executive Mordecai (Mo) Rosen announced the immediate closure and liquidation to staff on Monday, a move that affects about 300 employees — 100 in Israel and 200 in the United States.
The company’s website was unavailable Monday and Rosen could not be reached for comment.
Skybox scored several major investments over the years, raising approximately $335 million from venture capital and private equity, including a $50 million infusion as recent as February 2023.
Tufin, another Israeli company in the network security policy management space, has picked off the Skybox technology and business assets and is positioning itself as a lifeline for Skybox’s customers.
In a public statement, Tufin CEO Ray Brancato emphasized the firm’s financial stability and commitment to a smooth transition for affected clients.
“On February 24, 2025, Skybox made the difficult decision to close its operations effective immediately,” Brancato said. “For those impacted by this event, we understand this is an uncertain time, and we want to assure you that Tufin is here to help plot your path forward.”
Brancato said a new Tufin ExpressPath for Skybox Customers program is providing tools, expertise, and guidance to secure networks without disruption.
