Ledger appointed former Fireblocks executive Oded Blatman as Chief Information Officer and Chief Security Officer, overseeing network and infrastructure security, product security, physical and workplace security, internal IT, and enterprise risk management. Ledger said AI is lowering the cost and time required to find vulnerabilities, making attacks more complex and larger in scale, and requiring defenders to respond at the same speed. Blatman previously spent five years at Fireblocks and served as global CISO of Bank Hapoalim, Israel’s largest bank.
