Editor’s note: October is Cybersecurity Awareness Month, and we're celebrating with a series of security announcements this week. See our earlier posts on new security protections tailored for you, our new Advanced Protection Program, and our progress fighting phishing.



Security has always been one of Chrome’s core principles—we constantly work to build the most secure web browser to protect our users. Two recent studies concluded that Chrome was the most secure web browser in multiple aspects of security, with high rates of catching dangerous and deceptive sites, lightning-fast patching of vulnerabilities, and multiple layers of defenses.

About a year ago, we announced that we would begin marking all sites that are not encrypted with HTTPS as “not secure” in Chrome. We wanted to help people understand when the site they're on is not secure, and at the same time, provide motivation to that site's owner to improve the security of their site. We knew this would take some time, and so we started by only marking pages without encryption that collect passwords and credit cards. In the next phase, we began showing the “not secure” warning in two additional situations: when people enter data on an HTTP page, and on all HTTP pages visited in Incognito mode.
