Donald Trump has nominated Palantir's own security chief to run the agency that guards the federal government's civilian networks, at a time when Palantir's software already runs through the Department of Homeland Security that the agency belongs to. The White House named Michael LoSapio, Palantir's chief information security officer, as director of the Cybersecurity and Infrastructure Security Agency on Monday.

CISA is meant to defend civilian government networks from hackers and spies. It has gone almost 22 months without a Senate-confirmed leader, and its staff has fallen by about a third since Trump took office. The nomination follows three large breaches, at DHS, the FBI and the Pentagon, disclosed in the past three months.

In February DHS signed a purchasing agreement with Palantir worth up to $1 billion over five years, which lets any part of the department buy Palantir software without a fresh tender. That reach is departmentwide and could extend to the Secret Service, FEMA, TSA and CISA itself. If LoSapio is confirmed, the man in charge of checking the security of those systems will have come straight from the company selling them.
