All Google products are continuously protected by one of the world’s most advanced security infrastructures. This built-in security automatically detects and prevents online threats, so you can be confident your private information is safe.

Encryption brings a higher level of security and privacy to our services. When you send an email, share a video, visit a website, or store your photos, the data you create moves between your device, services, and our data centers. We protect this data with multiple layers of security, including leading encryption technology like HTTPS and Transport Layer Security.

We’ll proactively notify you if we detect something we think you should know about, like a suspicious login or a malicious website, file, or app, and we’ll provide guidance to help you strengthen your security. For example, on Gmail, we’ll warn you before you download an attachment that could put your security at risk or if someone logs in to your account from a device not associated with you. When we detect something suspicious in your account, we’ll send a notification to your inbox or phone so you can protect your account with one click.

Your online experience can be affected and your security compromised by ads that carry malware, cover the content you are trying to see, promote fake products, or otherwise violate our advertising policies. We take this problem very seriously. Every year we block billions of bad ads – on average, 100 per second – through a combination of live reviewers and sophisticated software. We also give you tools to report offensive ads and control what types of ads you see. And we actively publish our insights and best practices to help make the internet safer for all.
