Leo Taddeo, a top cyber cop at the Federal Bureau of Investigation, is leaving after more than two decades in government to become the chief security officer at security-software company Cryptzone.

Mr. Taddeo, 49, is stepping down as the head of the FBI’s special operations and cyber division, a position he held for the past two years. He supervised a number of high-profile cases, including the investigation into the online drug black market called Silk Road, which resulted in the conviction and life sentence of its founder Ross Ulbricht. Mr. Taddeo also helped lead the probe into the cybersecurity attack on J.P. Morgan Chase & Co., a breach that affected millions of households.
