Skybox Security, a cybersecurity firm that raised over $300 million in funding, has abruptly shut down, laying off its entire workforce of around 300 employees across Israel and the United States. The closure follows the sale of the company’s business and technology assets to its rival, Israeli firm Tufin.
The shutdown was announced by Skybox CEO Mordecai (Mo) Rosen on February 24, 2025, during a meeting with staff. Reports from the company’s Israeli headquarters indicated that the decision to liquidate came without warning, and the company’s website went offline shortly after the announcement.
Skybox, which had attracted significant venture capital investment—including a $50 million injection as recently as February 2023—had been struggling despite its funding. In a statement, Tufin CEO Ray Brancato expressed his company’s commitment to supporting Skybox’s clients during the transition. He emphasized Tufin’s stability and assured customers that they would be well-supported in navigating this change.
Tufin, which operates in the same network security policy management space, has acquired the technology and assets from Skybox, positioning itself as a solution for customers left in the lurch.
