Two top officials with expertise in cybersecurity and information technology are leaving the Securities and Exchange Commission, the agency announced Wednesday.

Chief Information Officer Pamela Dyson is heading to the Federal Reserve Bank of New York, where she will serve as CIO and head of the central bank’s technology group.

The current chief technology officer, Charles Riddle, will step into her position to become acting CIO, the SEC said.

Riddle joined the SEC in 2016 from the U.S. Government Publishing Office, where he served as CIO.

Further, Christopher Hetner, the senior advisor to SEC Chairman Jay Clayton for cybersecurity policy, is departing. However, he will stay at the SEC until his replacement is named and moved into place, according to the agency.

Hetner is the agency’s first “cyber czar,” having created the position in 2016. He also served under two former chairs, Mary Jo White and then-Acting Chairman Michael Piwowar.

Hetner interacted with other federal financial agencies and regulators to work on cybersecurity issues, including as the designated SEC representative on the U.S. Treasury Department-led Financial Banking Information Infrastructure Committee (FBIIC). His reach was global as well, having served as the SEC representative to the G-7 Cyber Expert Group.

Dyson joined the SEC in 2010, moving up to become CIO in February 2015 after first serving as acting CIO for several months prior, according to the SEC.

Like Hetner, she played a key role in the creation and management of IT and cyber services, according to the statement issued Thursday by the SEC. Dyson was responsible for creation of the agency’s “core cloud capability” through Amazon Web Services Inc., as well as for its digital transformation capabilities. She also helped develop and support the SEC’s cyber uplift program.

The SEC is also looking to fill another key IT position, according to a listing of government jobs online. The agency has posted an opening for a deputy chief information security officer, reporting to the chief information security officer (CISO).

Neither Dyson’s nor Hetner’s job is yet listed, though other federal agencies are also seeking a CIO.
