From call centers to identity systems to the security operations center, Hernandez keeps arriving when a sprawling enterprise platform needs a new shape. At BlueVoyant, the assignment is to make cyber defense faster, more unified, and useful with or without a managed service wrapped around it.
James (Jim) Rosenthal co-founded BlueVoyant in 2017 and built it from a startup into a global cybersecurity company with more than 650 employees across five continents. A former Chief Operating Officer of Morgan Stanley, where he answered to the CEO and board for cybersecurity, he turned a Wall Street obsession with protecting the financial system into a company that defends businesses and governments against internal and supply-chain threats. In May 2026 he handed the CEO role to John Hernandez and became Chairman of the Board.
