Our powerful Galaxy security solutions provide multiple ways to protect you from these cybersecurity threats by securing your device and helping control your privacy. Auto Blocker and Message Guard are two of these safeguards.

Auto Blocker

Auto Blocker is all about choice — providing an opt-in package of additional security measures so that you are completely in control to choose whether you want to explore the customizations enabled by Galaxy’s ecosystem. Auto Blocker will protect your Galaxy device and personal data by preventing app installations from unauthorized sources. The feature will also check for malware and other cybersecurity threats, immediately blocking any malicious activity that could come as a result.

One example of Auto Blocker in action is the prevention of what many people call sideloading, or downloading apps from unverified sources. There are numerous benefits to intentional sideloading, such as added customizations to your phone. But if you do not typically sideload, potential attacks that can come in the form of social engineering fraud like voice phishing — in which threat actors trick you over the phone and talk you into installing malicious software.

The extra level of protection that Auto Blocker provides also stops harmful commands from entering your physical USB port — which could come in handy when charging your phone through an outlet at a public space like an airport.

Turning on Auto Blocker is a quick and simple process that takes less than a minute. Open Settings, go to Security and Privacy, then tap Auto Blocker and select On.

Message Guard

Cybersecurity threats come in many forms, and each year they become even more sophisticated. One threat that is becoming increasingly common is the zero-click attack, which exploits vulnerabilities in your device software. This can take place any time an image is received and does not require any action whatsoever on the user’s part.

For instance, your phone receives an image and vibrates gently in your pocket or on your bedside table before going still. You haven’t touched your phone or facilitated any input, but someone may already be reading your messages, browsing your gallery or copying your bank details.

Samsung’s Message Guard will neutralize any potential threats that might be hiding in the image before it has a chance to do any harm by effectively trapping the file in an isolated space on your device. While the image is put into quarantine, Samsung Message Guard checks the file bit by bit — processing it in a controlled environment to prevent infection to the rest of your device.

Message Guard works with a range of popular messaging apps that you probably already use, from Google and Samsung apps to Messenger, Telegram and WhatsApp. You don’t need to worry about initiating the process either since Message Guard runs silently and effectively 24/7 in the background without needing to be activated in any way.

Although there is no doubt that cybersecurity threats will continue to evolve and become increasingly common, Samsung’s priority is to always keep you safe because privacy can only be assured with strong security. However you choose to live your life, Galaxy is there — watching your back and ensuring you stay in control.

Security Updates for Longer

While it’s important to have robust security features, it is also crucial to keep them up to date so you are protected against the latest threats. That’s why Samsung is providing up to seven years of security updates and seven years of operating system upgrades, starting with the Galaxy S24 series.¹ This is the longest period of software support currently available for mobile devices, allowing users to keep their phones safely and more reliably for longer.

Leading the Way in Mobile Security

Samsung prides itself in offering unmatched security to its users with Samsung Knox, its defense-grade security platform and cutting-edge technologies such as the industry’s strongest security chip, the embedded Secure Element (eSE);² a Secure Processor to protect against physical attacks; and the recently introduced Knox Vault, which adds another layer of security. As one of the few companies to design and develop its own products, software and services, Samsung offers true end-to-end protection, from the moment new product planning begins until a product is retired. By embedding security across every single layer of its devices, from the chip all the way up to the apps, Samsung can protect personal information in real-time and preemptively respond to increasingly advanced mobile threats.

“At Samsung, our number one priority is offering the best and most secure mobile experience to our users, and we’re constantly optimizing the security of our products and services,” said Seungwon Shin, VP & Head of Security Team at Mobile Communications Business, Samsung Electronics. “Mobile devices play such an important role in our lives, it’s only natural that we want to hold onto them longer. That’s why, thanks to the latest technology advancements, we’re committing to securing Galaxy devices for even longer, so that everything that should be kept protected stays protected.”

Securing Over 130 Models

Over the past decade, Samsung has made significant progress in streamlining and speeding up its regular security updates. Samsung worked closely with its OS and chipset partners, as well as over 200 carriers around the world to ensure that billions of Galaxy devices receive timely security patches. Samsung remains committed to offering security updates as quickly as possible to always stay one step ahead and keep its users safe.

A Collaborative Approach to Mobile Security

Samsung believes openness and collaboration are critical to offering the best mobile experiences that people can trust. Samsung has worked closely with over 1,000 partners to establish security standards for all Android devices, including the first-of-its-kind regular security update program in 2015, and partnered with the broader security research community to ensure consumers have the most secure mobile experience possible.
