Today, Google announced that they will be making encrypted search the default for users who are logged into a Google account. This means that third parties, including both your Internet Service Provider (ISP) and the sites you ultimately visit (unless you click on an ad) will not be able to see exactly what you searched for. We're happy to see Google expanding access to secure search. We hope that it will continue to expand protections like this to all searches and hope other search engines will also do the same.
