Samsung Electronics Co., Ltd. today announced a new set of security and privacy updates rolling out with its upcoming Samsung Galaxy smartphones with One UI 8.

These updates reinforce Samsung’s commitment to delivering powerful, trusted mobile technology in a rapidly evolving digital world by introducing new protections for on-device AI, expanding cross-device threat detection and enhancing network security with quantum-resistant encryption.

Next-Generation Mobile Security for AI Personalisation

Samsung is introducing Knox Enhanced Encrypted Protection (KEEP), a new architecture designed to safeguard the next generation of personalised, AI-powered features, as its latest innovation in mobile security.

KEEP creates encrypted, app-specific storage environments within the device’s secure storage area, ensuring that each app can access only its own sensitive information and nothing more.

Supporting Galaxy’s Personal Data Engine (PDE), KEEP helps secure a user’s deeply personal insights, such as routines and preferences, that enable features like Now Brief and Smart Gallery search.

These insights stay entirely on-device, protected by KEEP and further secured by Knox Vault, Samsung’s tamper-resistant hardware security environment.

The result is a seamless foundation for Galaxy AI that delivers personalised intelligence while keeping data tightly contained and under the user’s control.

KEEP’s system-level structure allows it to scale across Galaxy AI innovations. In addition to PDE, it now protects Now Brief, Smart Suggestions and other on-device features that rely on user-specific inputs, enabling more advanced AI experiences without compromising privacy.

With KEEP, Samsung is redefining how mobile devices safeguard data in the background to elevate privacy from a setting to an embedded design principle.

Smarter, More Connected Threat Response with Knox Matrix

As AI becomes more integrated across the ecosystem, Samsung is advancing protections that offer not just stronger security but greater transparency and control for users, with Knox Matrix leading the way.

Through One UI 8, Samsung is evolving Knox Matrix to deliver more proactive and user-friendly protection for connected Galaxy devices.

When a device is flagged for serious risk, such as system manipulation or identity forgery, it is designed to automatically sign out of the Samsung Account, cutting off access to cloud-connected services to prevent threats from spreading.

Users are notified across their connected Galaxy devices and guided to the ‘Security status of your devices’ page, where they can review the issue and take action.

Even devices without the latest security status updates trigger a yellow-level warning, helping users respond before vulnerabilities grow.

Together, these updates make Samsung Galaxy’s ecosystem-level protection more dynamic, intuitive and visible, empowering users to maintain trust across all their devices with more confidence and clarity.

Secure Wi-Fi Strengthened with Quantum-Resistant Encryption

In continuation of its commitment to quantum-safe security, Samsung is bringing post-quantum cryptography to Secure Wi-Fi, extending the trusted approach first introduced on the Galaxy S25 series through Post-Quantum Enhanced Data Protection (EDP).

Secure Wi-Fi is now being upgraded with a new cryptographic framework designed to strengthen network protection against emerging threats, particularly those anticipated in the era of quantum computing.

This enhancement secures the key exchange process at the core of encrypted connections, helping ensure robust privacy even over public networks.

Quantum computing, once fully realised, could undermine many of today’s data protection methods.

By integrating post-quantum cryptography, Secure Wi-Fi is built to withstand future attacks that capture encrypted data with the intent to break it once quantum technology matures – a tactic known as “harvest now, decrypt later.”

This upgrade fortifies the secure tunnel between Galaxy devices and Samsung servers, reinforcing the integrity of data transmissions in high-risk environments like public Wi-Fi.

In addition to this future-ready foundation, Secure Wi-Fi offers a suite of advanced privacy features:

• Auto Protect: Automatically activates in public places like cafés, airports or hotels, securing Wi-Fi connections without requiring user action.
• Enhanced Privacy Protection (EPP): Encrypts internet traffic and routes it through multiple layers, combining packet encryption and relay to anonymise device information and help prevent tracking.
• Protection Activity: Provides visibility into protection history by showing which apps and networks were secured and how much data was encrypted over time.

A Trusted Platform with Built-In Safeguards

In addition to its latest innovations, Samsung continues to strengthen the core protections that underpin the Galaxy experience. These features reflect a multi-layered security approach that protects across hardware and software, while giving users greater visibility and control:

• Knox Vault secures sensitive credentials such as passwords, PINs and biometrics in a physically isolated environment, helping to keep them protected even if the main operating system is compromised.
• Auto Blocker helps provide defence by default, blocking unauthorised app installs, restricting command-based attacks and mitigating risks from potential zero-click threats.
• Advanced Intelligence Settings gives users the option to turn off online data processing for AI features, so personal information can stay on-device, fully under their control.
• Enhanced Theft Protection helps protect personal data even in high-risk situations such as robbery, using safeguards like Identity Check and Security Delay to prevent unauthorised access.

This latest set of updates reinforces Samsung’s long-standing commitment to mobile security that evolves with innovation.

It strengthens on-device privacy for personalised AI with KEEP, expands transparency and user control through Knox Matrix, and introduces quantum-resistant protection to Secure Wi-Fi for a more future-ready Galaxy experience.

As new security challenges emerge, Samsung remains focused on delivering safeguards that are built in, always on and ready for what’s next.
