Google Pixel 7 and Pixel 7 Pro: The next evolution in mobile security

Every day, billions of people around the world trust Google products to enrich their lives and provide helpful features – across mobile devices, smart home devices, health and fitness devices, and more. We keep more people safe online than anyone else in the world, with products that are secure by default, private by design and that put you in control. As our advancements in knowledge and computing grow to deliver more help across contexts, locations and languages, our unwavering commitment to protecting your information remains.

That’s why Pixel phones are designed from the ground up to help protect you and your sensitive data while keeping you in control. We’re taking our industry-leading approach to security and privacy to the next level with Google Pixel 7 and Pixel 7 Pro, our most secure and private phones yet, which were recently recognized as the highest rated for security when tested among other smartphones by a third-party global research firm.1

Pixel phones also get better every few months with Feature Drops that provide the latest product updates, tips and tricks from Google. And Pixel 7 and Pixel 7 Pro users will receive at least five years of security updates2, so your Pixel gets even more secure over time.

Your protection, built into Pixel

Your digital life and most sensitive information lives on your phone: financial information, passwords, personal data, photos – you name it. With Google Tensor G2 and our custom Titan M2 security chip, Pixel 7 and Pixel 7 Pro have multiple layers of hardware security to help keep you and your personal information safe. We take a comprehensive, end-to-end approach to security with verifiable protections at each layer - the network, application, operating system and multiple layers on the silicon itself. If you use Pixel for your business, this approach helps protect your company data, too.

Google Tensor G2 is Pixel’s newest powerful processor custom built with Google AI, and makes Pixel 7 faster, more efficient and secure3. Every aspect of Tensor G2 was designed to improve Pixel's performance and efficiency for great battery life, amazing photos and videos.

Tensor’s built-in security core works with our Titan M2 security chip to keep your personal information, PINs and passwords safe. Titan family chips are also used to protect Google Cloud data centers and Chromebooks, so the same hardware that protects Google servers also secures your sensitive information stored on Pixel.

And, in a first for Google, Titan M2 hardware has now been certified under Common Criteria PP0084: the international gold standard for hardware security components also used for identity, SIM cards, and bankcard security chips.4 This means that the Titan M2 hardware meets the same rigorous protection guidelines trusted by banks, carriers, and governments.

To achieve the certification we went through rigorous third party lab testing by SGS Brightsight, a leading international security lab, and received certification against CC PP0084 with AVA_VAN.5 for the Titan M2 hardware and cryptography library from the Netherlands scheme for Certification in the Area of IT Security (NSCIB). Of all those numbers and acronyms the part we’re most proud of is that Titan hardware passed the highest level of vulnerability assessment (AVA_VAN.5) - the truest measure of resilience to advanced, methodical attacks.

This process took us more than three years to complete. The certification not only requires chip hardware to resist invasive penetration testing, but also mandates audits of the chip design and manufacturing process itself. The benefit for consumers? The now certified Titan M2 chip makes your phone even more resilient to sophisticated attacks.5

Private by design

Evolving our security and privacy standards to our fast-paced world requires new approaches as well. Earlier this year at I/O, we introduced Protected Computing, a toolkit of technologies that transforms how, when, and where personal data is processed to protect your privacy and security. Our approach focuses on:

  1. Minimizing your data footprint, by shrinking the amount of personally identifiable data altogether
  2. De-identifying data, with a range of anonymization techniques so it’s not linked to you
  3. Restricting data access using technologies like end-to-end encryption and secure enclaves.

Many elements of Protected Computing can be found on the new Pixel 7:

On Android, Private Compute Core keeps your information and AI-driven personalizations private with on-device processing. Data from features like Now Playing, Live Caption and Smart Reply in Messages are all processed on device and are never sent to Google to maintain your privacy. And even your device backups to the cloud are end-to-end encrypted using Titan in the cloud.6

With Google Tensor G2, Pixel’s advanced privacy protection also now covers audio data from events like cough and snore detection on Pixel 7.7 Audio data from cough and snore detection is never stored by or sent to Google to maintain your privacy.

On Pixel 7, Tensor G2 helps safeguard your system with the Android Virtualization Framework, unlocking improved security protections like enabling system update integrity checking to occur on-the-fly, reducing boot time after an update.

Extra protection when you’re online

Helping to keep you safe when you use your phone to browse the web and use apps is also critical. This is where a Virtual Private Network (VPN) comes in. A VPN helps protect your online activity from anyone who might try to access it by encrypting your network traffic to turn it into an unreadable format, and masking your original IP address. Typically, if you want a VPN on your phone, you need to get one from a third party.

To ensure more people have access to enhanced security, later this year, Pixel 7 and Pixel 7 Pro owners will be able to use VPN by Google One, at no extra cost.8 VPN by Google One is verifiably private, and will allow you to tap into Google’s world-class security for peace of mind when you connect online. With VPN by Google One, Pixel helps protect your online activity at a network level. Think of it like an extra layer of protection for your online security.

VPN by Google One creates a high-performance secure connection to the web so your browsing and app data is sent and received via an encrypted pathway. A few simple taps will activate the VPN to help keep your network traffic private from internet providers and hackers, giving you peace of mind when using cellular data, home Wi-Fi, and especially when connected to public networks, like a café or airport Wi-Fi. No need to worry about online intruders, hackers, or unsecure networks.

Unlike traditional VPN services, VPN by Google One uses Protected Computing to technically make it impossible for anyone at a network level, even VPN by Google One, to link your online traffic with your account or identity. VPN by Google One will be available at no extra cost as long as your phone continues to receive security updates. See here to learn more about VPN by Google One.

More protection and privacy with Android 13

Pixel 7 and Pixel 7 Pro have built-in anti-phishing protections from Android that scan for potential threats from phone calls, text messages and emails, and more anti-phishing protections enabled out-of-the-box than smartphones from leading competitors.9 In fact, Messages alone protects consumers against 1.5 billion spam messages per month.

Android also resets permissions for apps you haven’t used for an extended time. In a typical month, Android automatically resets more than 3 billion permissions affecting more than 1 billion installed apps. Similarly, if you use clipboard on Android 13, your history is automatically deleted after a period of time. This blocks apps running in the foreground from seeing old information that you previously copied.

You’re in control

Core to your safety is knowing that you’re in control. You always have control over your settings and devices across all of our products. With Android 13, coming soon through a Feature Drop, Pixel 7 and Pixel 7 Pro will give you additional ways to stay in control of your privacy and what you share with first and third-party apps. With Quick Settings, you can act on security issues as they arise, or review which apps are running in the background and easily stop them. You’ll have a single destination for reviewing your security and privacy settings, risk levels and information, making it easier to manage your safety status.

With this new experience, you can review actionable steps to improve your safety status, like revoking a permission or app. This page will also have new action cards to notify you of any safety risks and provide timely recommendations on how to enhance your privacy. And with a single tap, you can grant or remove permissions to data that you don’t want to share with compatible apps. This will be coming soon first to Pixel devices later this year, and other Android phones soon after.

Verifiably secure

As computing extends to more devices and use cases, Google is committed to innovating in security and being transparent about the processes that we take to get there. We are leading the industry in verifiable security by not only having products that are tested against real-world threats (like advanced spam, phishing and malware attacks), but also in publishing the results of penetration tests, security audits, and industry certifications across our Pixel and Nest products.

Another way to verify our security is through our Android and Google Devices Security Reward Program where we reward security researchers who find vulnerabilities across products, including Pixel, Nest and Fitbit. Last year on Android, we awarded nearly $3 million dollars, creating a valuable feedback loop between us and the security research community and, most importantly, helping us keep our users safe.

Pixel 6: Setting a new standard for mobile security

With Pixel 6 and Pixel 6 Pro, we’re launching our most secure Pixel phone yet, with 5 years of security updates and the most layers of hardware security. These new Pixel smartphones take a layered security approach, with innovations spanning across the Google Tensor system on a chip (SoC) hardware to new Pixel-first features in the Android operating system, making it the first Pixel phone with Google security from the silicon all the way to the data center. Multiple dedicated security teams have also worked to ensure that Pixel’s security is provable through transparency and external validation.

Secure to the Core

Google has put user data protection and transparency at the forefront of hardware security with Google Tensor. Google Tensor’s main processors are Arm-based and utilize TrustZone™ technology. TrustZone is a key part of our security architecture for general secure processing, but the security improvements included in Google Tensor go beyond TrustZone.

Figure 1. Pixel Secure Environments

The Google Tensor security core is a custom designed security subsystem dedicated to the preservation of user privacy. It's distinct from the application processor, not only logically, but physically, and consists of a dedicated CPU, ROM, one-time-programmable (OTP) memory, crypto engine, internal SRAM, and protected DRAM. For Pixel 6 and 6 Pro, the security core’s primary use cases include protecting user data keys at runtime, hardening secure boot, and interfacing with Titan M2TM.

Your secure hardware is only as good as your secure OS, and we are using Trusty, our open source trusted execution environment. Trusty OS is the secure OS used both in TrustZone and the Google Tensor security core.

With Pixel 6 and Pixel 6 Pro your security is enhanced by the new Titan M2TM, our discrete security chip, fully designed and developed by Google. In this next generation chip, we moved to an in-house designed RISC-V processor, with extra speed and memory, and made it even more resilient to advanced attacks. Titan M2TM has been tested against the most rigorous standard for vulnerability assessment, AVA_VAN.5, by an independent, accredited evaluation lab. Titan M2™ supports Android Strongbox, which securely generates and stores keys used to protect your PINs and password, and works hand-in-hand with Google Tensor security core to protect user data keys while in use in the SoC.

Moving a step higher in the system, Pixel 6 and Pixel 6 Pro ship with Android 12 and a slew of Pixel-first and Pixel-exclusive features.

Enhanced Controls

We aim to give users better ways to control their data and manage their devices with every release of Android. Starting with Android 12 on Pixel, you can use the new Security hub to manage all your security settings in one place. It helps protect your phone, apps, Google Account, and passwords by giving you a central view of your device’s current configuration. Security hub also provides recommendations to improve your security, helping you decide what settings best meet your needs.

For privacy, we are launching Privacy Dashboard, which will give you a simple and clear timeline view of the apps that have accessed your location, microphone and camera in the last 24 hours. If you notice apps that are accessing more data than you expected, the dashboard provides a path to controls to change those permissions on the fly.

To provide additional transparency, new indicators in Pixel’s status bar will show you when your camera and mic are being accessed by apps. If you want to disable that access, new privacy toggles give you the ability to turn off camera or microphone access across apps on your phone with a single tap, at any time.

The Pixel 6 and Pixel 6 Pro also include a toggle that lets you remove your device’s ability to connect to less-secure 2G networks. While necessary in certain situations, accessing 2G networks can open up additional attack vectors; this toggle helps users mitigate those risks when 2G connectivity isn’t needed.

Built-in security

By making all of our products secure by default, Google keeps more people safe online than anyone else in the world. With the Pixel 6 and Pixel 6 Pro, we’re also ratcheting up the dial on default, built-in protections.

Our new optical under-display fingerprint sensor ensures that your biometric information is secure and never leaves your device. As part of our ongoing security development lifecycle, Pixel 6 and 6 Pro’s fingerprint unlock has been externally validated by security experts as a strong and secure biometric unlock mechanism meeting the Class 3 strength requirements defined in the Android 12 Compatibility Definition Document (CDD).

Phishing continues to be a huge attack vector, affecting everyone across different devices.

The Pixel 6 and Pixel 6 Pro introduce new anti-phishing protections. Built-in protections automatically scan for potential threats from phone calls, text messages, emails, and links sent through apps, notifying you if there’s a potential problem.

Users are also now better protected against bad apps by enhancements to our on-device detection capabilities within Google Play Protect. Since its launch in 2017, Google Play Protect has provided the ability to detect malicious applications even when the device is offline. The Pixel 6 and Pixel 6 Pro uses new machine learning models that improve the detection of malware in Google Play Protect. The detection runs on your Pixel, and uses a privacy preserving technology called federated analytics to discover commonly-run bad apps. This will help to further protect over 3 billion users by improving Google Play Protect, which already analyzes over 100 billion apps every day to detect threats.

Many of Pixel’s privacy-preserving features run inside Private Compute Core, an open source sandbox isolated from the rest of the operating system and apps. Our open source Private Compute Services manages network communication for these features, and uses federated learning, federated analytics, and private information retrieval to improve features while preserving privacy. Some features already running on Private Compute Core include Live Caption, Now Playing, and Smart Reply suggestions.

Google Binary Transparency (GBT) is the newest addition to our open and verifiable security infrastructure, providing a new layer of software integrity for your device. Building on the principles pioneered by Certificate Transparency, GBT helps ensure your Pixel is only running verified OS software. It works by using append-only logs to store signed hashes of the system images. The logs are public and can be used to verify that what’s published is the same as what’s on the device – giving users and researchers the ability to independently verify OS integrity for the first time.

Beyond the Phone

Defense-in-depth isn’t just a matter of hardware and software layers. Security is a rigorous process. Pixel 6 and Pixel 6 Pro benefit from in-depth design and architecture reviews, memory-safe rewrites to security critical code, static analysis, formal verification of source code, fuzzing of critical components, and red-teaming, including with external security labs to pen-test our devices. Pixel is also part of the Android Vulnerability Rewards Program, which paid out $1.75 million last year, creating a valuable feedback loop between us and the security research community and, most importantly, helping us keep our users safe.

Capping off this combined hardware and software security system, is the Titan Backup Architecture, which gives your Pixel a secure foot in the cloud. Launched in 2018, the combination of Android’s Backup Service and Google Cloud’s Titan Technology means that backed-up application data can only be decrypted by a randomly generated key that isn't known to anyone besides the client, including Google. This end-to-end service was independently audited by a third party security lab to ensure no one can access a user's backed-up application data without specifically knowing their passcode.

To top it all off, this end-to-end security from the hardware across the software to the data center comes with no fewer than 5 years of guaranteed Android security updates on Pixel 6 and Pixel 6 Pro devices from the date they launch in the US. This is an important commitment for the industry, and we hope that other smartphone manufacturers broaden this trend.

Together, our secure chipset, software and processes make Pixel 6 and Pixel 6 Pro the most secure Pixel phone yet.
