SAN FRANCISCO—Google is disclosing how much of the traffic to its search engine and other services is being protected from hackers as part of its push to encrypt all online activity.
Encryption shields 77 percent of the requests sent from around the world to Google’s data centers, up from 52 percent at the end of 2013, according to company statistics released Tuesday.
The numbers cover all Google services except its YouTube video site, which has more than 1 billion users. Google plans to add YouTube to its encryption breakdown by the end of this year.
