Getting a security clearance has long been one of the federal government's most frustrating bottlenecks. Background investigations that once took months — sometimes years — are now being compressed into hours, according to an official at the Defense Counterintelligence and Security Agency (DCSA).
The agency is deploying AI to handle the granular, repetitive judgments buried inside each investigation. "We're trying to use AI...to make these little tiny decisions, and then bring that up to a human," the DCSA official said, according to Defense One. The model is explicitly human-in-the-loop: the AI does the legwork of sifting through records and flagging relevant information, while a person makes the final call.
Security clearances gate access to classified information across the military, intelligence community, and defense contractors. A backlog in processing them has historically left thousands of personnel — and the projects they support — in limbo. Faster clearances could accelerate hiring pipelines for sensitive roles and reduce the national security risk that comes from staffing gaps.
The DCSA approach reflects a broader trend in government: using AI not to replace human judgment on consequential decisions, but to reduce the volume of mechanical work that precedes it. By automating the sorting and preliminary assessment of records, investigators can focus attention where it actually matters.
If this speed holds at scale, it could fundamentally change how the U.S. government builds and maintains its cleared workforce — and how quickly it can respond when those needs surge.
