CHINA WATCHMicrosoft Failed to Disclose Key Details About Use of China-Based Engineers in U.S. Defense Work, Record Shows
The tech giant is required to regularly provide U.S. officials with its plan for keeping government data safe from hacking. Yet a copy of Microsoft’s security plan obtained by ProPublica makes no reference to the company’s China-based operations.
Microsoft, as a provider of cloud services to the U.S. government, is required to regularly submit security plans to officials describing how the company will protect federal computer systems.
Yet in a 2025 submission to the Defense Department, the tech giant left out key details, including its use of employees based in China, the top cyber adversary of the U.S., to work on highly sensitive department systems, according to a copy obtained by ProPublica. In fact, the Microsoft plan viewed by ProPublica makes no reference to the company’s China-based operations or foreign engineers at all.
The document belies Microsoft’s repeated assertions that it disclosed the arrangement to the federal government, showing exactly what was left out as it sold its security plan to the Defense Department. The Pentagon has been investigating the use of foreign personnel by IT contractors in the wake of reporting by ProPublica last month that exposed Microsoft’s practice.
Our work detailed how Microsoft relies on “digital escorts” — U.S. personnel with security clearances — to supervise the foreign engineers who maintain the Defense Department’s cloud systems. The department requires that people handling sensitive data be U.S. citizens or permanent residents.
Microsoft’s security plan, dated Feb. 28 and submitted to the department’s IT agency, distinguishes between personnel who have undergone and passed background screenings to access its Azure Government cloud platform and those who have not. But it omits the fact that workers who have not been screened include non-U.S. citizens based in foreign countries. “Whenever non-screened personnel request access to Azure Government, an operator who has been screened and has access to Azure Government provides escorted access,” the company said in its plan.
The document also fails to disclose that the screened digital escorts can be contractors hired by a staffing company, not Microsoft employees. ProPublica found that escorts, in many cases former military personnel selected because they possess active security clearances, often lack the expertise needed to supervise engineers with far more advanced technical skills. Microsoft has told ProPublica that escorts “are provided specific training on protecting sensitive data” and preventing harm.
Microsoft’s reference to the escort model comes two-thirds of the way into the 125-page document, known as a “System Security Plan,” in several paragraphs under the heading “Escorted Access.” Government officials are supposed to evaluate these plans to determine whether the security measures disclosed in them are acceptable.
