The nation’s largest counterintelligence unit aims to use artificial intelligence tools to speed security clearance reviews for people and companies seeking to do sensitive work on behalf of the government. The Defense Counterintelligence and Security Agency can use AI to reduce parts of the vetting process from “months to hours,” said Mark Nehmer, an agency analytics and innovation chief who spoke Tuesday on a panel at the *Defense One *Tech Summit in Virginia. DCSA is the Defense Department’s main agency for conducting background investigations and vetting personnel for access to classified information, and serves as a key determinant for whether companies are eligible to work with military and intelligence agencies. A recent congressionally-approved [acquisition overhaul](https://www.acquisition.gov/far-overhaul), which encourages defense officials to prioritize goods and services from the commercial market, means that the counterintelligence agency will have to process some 43,000 clearance requests per year, he estimated. “We’re trying to use AI exquisitely, use AI to make these little tiny decisions, and then bring that up to a human, so they can actually have a package of evidence to say, ‘I asked, and this is exactly the conclusion I will come to as a senior analyst that has to make those decisions day-in and day-out,’” Nehmer said. He did not specify what AI systems would be used for the efforts. The remarks are significant because they highlight how the government is applying AI to a key national security function that determines who has access to clearances, and they add another case to a long list of examples showing how the federal enterprise is using AI to speed operations. DCSA has led the government’s background check process since 2019, when the Office of Personnel Management [handed off](https://www.defenseone.com/technology/2019/10/pentagon-has-officially-taken-over-security-clearance-process/160315/) its National Background Investigations Bureau to the Pentagon. DCSA’s use of AI builds on a years-long effort to [automate and overhaul](https://www.defenseone.com/policy/2025/01/officials-say-federal-employee-background-check-system-overhaul-finally-right-track/401980/) the federal background-check system. The agency has enrolled millions of clearance holders in continuous vetting under an initiative known as Trusted Workforce 2.0, though the broader modernization effort has faced repeated delays, cost overruns and congressional scrutiny. Over the weekend, the U.S. invoked an export control mechanism to essentially ban two major Anthropic frontier models, escalating debates over how Washington could exert itself over AI usage in the government. The decision has been [widely criticized](https://www.nextgov.com/artificial-intelligence/2026/06/industry-and-academia-call-administration-free-anthropics-ai-model/414194/?oref=ng-homepage-river). *GovExec Editor-in-Chief Frank Konkel contributed to this report.*
