Microsoft has announced that it will encrypt Bing search traffic by default from this summer.
Bing already offers the ability to encrypt searches, but the wider rollout is part of Microsoft's and the industry's plans to encourage the use of the security protocol.
"At Microsoft, we're committed to helping users keep their data safe and secure," said Bing senior product manager Duane Forrester in a blog post.
"That's why we support the industry's move to the use of TLS protocols as part of our effort to expand encryption across our networks and services.
"Bing has already been offering users the option to encrypt search traffic for about a year and a half.
"Beginning this summer, we will begin the process of encrypting search traffic by default. This means that traffic originating from Bing will increasingly come from https://www.bing.com as opposed to http://www.bing.com."
Forrester said that Microsoft is making other efforts to improve security, and will limit the amount of customer data that is exposed through any searches and make any sharing more transparent.
"Microsoft has a long history and deep commitment to helping protect our customers' data and the security of their systems," he added.
"While this change may impact marketers and webmasters, we believe that providing a more secure search experience for our users is important."
Forrester said that advertisers and webmasters could use a number of Bing tools to analyse results and traffic.
Encryption by default is becoming a theme of the internet industry, and a focus of regulators and international entities.
The United Nations said in May that encryption is a human right that should be preserved in the face of increasing national efforts to limit security tools in the US and the UK.
