Microsoft and Chinese technology giant Huawei Technologies are feeling the heat from each other’s government, according to The Wall Street Journal. Chinese antitrust regulators are investigating Microsoft, and Huawei has been shut out of the U.S. telecommunications-equipment market over concerns it might be a front for cyberspying. Now the two have joined forces in a “buyers guide,” meant to allay fears that each new information-technology contract poses a cybersecurity threat. Aimed at governments and corporations shopping for information- and communications-technology products and services, it was produced in cooperation with the nonprofit EastWest Institute. Rather than reviews and rankings, this buyers guide offers a discussion of security issues in technology development, manufacturing, distribution and supply-chain management.
