In 2007, we launched Safe Browsing, one of Google’s earliest anti-malware efforts. To keep our users safe, we’d show them a warning before they visited a site that might’ve harmed their computers.
And it has: In May 2016, we announced that Safe Browsing was protecting more than 2 billion devices from badness on the internet. Today we’re announcing that Safe Browsing has crossed the threshold to 3 billion devices. We’re sharing a bit more about how we got here, and where we’re going.
What is Safe Browsing?
You may not know Safe Browsing by name, since most of the time we’re invisibly protecting you, without getting in the way. But you may have seen a warning like this at some point:
This protective information that we generate—a curated list of places that are dangerous for people and their devices—is used across many of our products. It helps keep search results safe and keep ads free from badness; it’s integral to Google Play Protect and keeps you safe on Android; and it helps Gmail shield you from malicious messages.
And Safe Browsing doesn’t protect only Google’s products. For many years, Safari and Firefox have protected their users with Safe Browsing as well. If you use an up-to-date version of Chrome, Firefox or Safari, you’re protected by default. Safe Browsing is also used widely by web developers and app developers (including Snapchat), who integrate our protections by checking URLs before they’re presented to their users.
Protecting more people with fewer bits
In the days when web browsers were used only on personal computers, we didn’t worry much about the amount of data Safe Browsing sent over the internet to keep your browser current. Mobile devices changed all that: Slow connections, expensive mobile data plans, and scarce battery capacity became important new considerations.
So over the last few years, we’ve rethought how Safe Browsing delivers data. We built new technologies to make its data as compact as possible: We only send the information that’s most protective to a given device, and we make sure this data is compressed as tightly as possible. (All this work benefits desktop browsers, too!)
We initially introduced our new mobile-optimized method in late 2015 with Chrome on Android, made it more broadly available in mid-2016, when we also started actively encouraging Android developers to integrate it. With the release of iOS 10 in September 2016, Safari began using our new, efficient Safe Browsing update technology, giving iOS users a protection boost.
Safe Browsing in an AI-first world
The internet is at the start of another major shift. Safe Browsing has already been using machine learning for many years to detect much badness of many kinds. We’re continually evaluating and integrating cutting-edge new approaches to improve Safe Browsing.
Protecting all users across all their platforms makes the internet safer for everyone. Wherever the future of the internet takes us, Safe Browsing will be there, continuing to evolve, expand, and protect people wherever they are.
