WASHINGTON—
When it comes to protecting sensitive information from foreign hackers, President-elect Joe Biden’s team is largely on its own.
The federal government, which has some of the most sophisticated antihacking technologies in the world, is offering limited assistance to Mr. Biden’s transition operation in securing its email and other communications, despite concerns that the team is likely a top espionage target for Russia, China, and other adversaries, according to people familiar with the transition.
