Imagine this — you’re having a hectic Monday morning at work and then suddenly you receive a SmartThings alert that your dog is barking continuously.1 You’re worried sick but also unable to go home to check. What can you do?
Fortunately, your Samsung robot vacuum is there to save the day. How, you may ask? Well, this isn’t just any vacuum. It precisely maps your home with advanced camera technology so that it can proactively cater to varying needs. In this case, that means finding your dog2 to investigate the cause of the barking and to provide you with immediate peace of mind3.
These smart capabilities verge on life-changing but they must be balanced with ultra-smart, ultra-safe security. And that’s where Samsung Knox comes in, which sits at the core of Samsung home appliances, meaning multi-layered shields are there for you. It’s there to protect your information, your home, and your family against cyber-attacks. To understand how this level of protection is achieved, let’s dig deeper into what makes up Samsung’s comprehensive security.
Layer up to keep concern down
A great place to start is what happens when you begin an interaction with SmartThings-connected devices protected by Samsung Knox. When your robot vacuum checks up on your dog, it will monitor different scenes around your home, which might be private and sensitive. Knox ensures these are securely protected multiple times. The command you issued and as well as the monitoring video are always encrypted before being sent through the system, and then only decrypted at the destination4.
Not only that, but when the device is turned on, it continuously checks for unauthorised modifications to the firmware and stores important information in a separate hardware space. Combining these layers makes the devices safer for the user and difficult for potential attackers. You can feel assured that whether your information is being stored on your device or being shared with the server for verification, it is always tightly secured.
Knox Matrix: A security ecosystem like no other
Sometimes you may be curious how your information is protected when you share your private schedule like a business meeting or a doctor appointment on Samsung’s refrigerators with AI Family Hub. Also, you might like to see at a glance whether the security status of all Wi-Fi appliances in your home is properly maintained, and whether any information is leaking without your knowledge. Knox Matrix5 exists to solve these needs.
Knox Matrix is Samsung’s comprehensive security system, which extends protection across devices and networks using private blockchain technology. In addition to being protected through Knox’s multi-layered security, Samsung has started implementing a more advanced way of protection with Knox Matrix.
To make everything even safer, refrigerators with AI Family Hub6 adopted Credential Sync, a key feature of Knox Matrix. Simply, it updates a “secret key” created only for you, which is the only means of decrypting the private information registered on your refrigerator. So, your information is kept safe and protected when it’s stored on the fridge, or even when it’s shared with other SmartThings-connected appliances.
And there’s more; your devices will form a Trust Chain7. Think of it as a team of devices working together to protect each other. They constantly check in with one another to make sure your security status is fine. If one device notices something suspicious, it keeps you informed, including summarising the status at a glance in the security dashboard.
Simply put, your data — whether it’s a weekly schedule or the login credentials for your Samsung account — is securely protected from outsiders. And on the rare occasion something goes wrong, your devices team up to alert you and handle the issue together.
Security that only gets stronger
It’s 2025, and companies are making more promises than ever about the capabilities of their devices. How can you trust Samsung appliances to be truly safe? The results speak for themselves: Samsung was actually the first company in the global home appliance industry to be verified to the highest ‘Diamond’ level rating under UL Solutions’ Marketing Claim Verification IoT Security Rating Program and also has the largest number of verified appliances in the world8.
And to fully future-proof its devices, Samsung plans to regularly provide security updates via Smart Forward, and in the event of security vulnerabilities, immediate emergency updates will be offered. For your experience as an end user, that means you get peace of mind from knowing that Samsung is protecting you more comprehensively than ever before while working hard behind the scenes to innovate the future of appliance security. Your takeaway from this article? Samsung Knox lets you leverage the benefits of the AI era without security concerns. It’s always better to be safe.
