Exfiltrate is a verb that means to withdraw people from a dangerous position.

Our word of the day could be thought of as the opposite of ‘infiltrate,’ a word of Latin origin that means to secretly place people in an organization. To exfiltrate people means to secretly remove them. Both exfiltrate and infiltrate are often used in reference to spies or militaries.

After learning it was no longer safe for their operatives to be a part of the underground group, the FBI attempted to exfiltrate them from the scene. In cases like this it is always best to simply remove people at risk.
