Google introduces on-device AI scam protection in Chrome

Google has begun rolling out a new on-device artificial intelligence feature in its Chrome browser aimed at improving protection against online scams and malicious threats. The update, currently appearing in pre-release versions of Chrome, allows scam and malware detection to run entirely on the user’s device, without sending browsing data to Google’s cloud servers.

The feature, which was first announced in late 2024, is designed to provide real-time defense against fake websites, dangerous downloads and scam-related content. By processing data locally, Google says the system can offer faster responses while maintaining stronger user privacy.

Unlike previous security tools that relied heavily on cloud-based analysis, this on-device AI works independently. However, users are now required to make a clear choice. The scam detection feature is enabled by default, but Chrome includes an option that allows users to remove the AI models stored on their device. Disabling these models also turns off the scam protection system.

Security researcher Leo Peva has pointed out that Chrome contains a specific setting that controls on-device generative AI. While it currently supports security-related functions such as scam detection, some users have raised concerns that similar technology could be expanded to other uses in the future.

On-device AI for security has generally been well received, as it reduces data sharing and improves transparency. Still, questions remain about how effective the protection will be if a large number of users choose to disable the feature. There is also ongoing discussion about whether Chrome will offer more detailed controls over how on-device AI is used going forward.

Despite these concerns, experts agree that applying artificial intelligence strictly for security purposes has clear benefits. As online scams and malware continue to evolve, tools that operate directly on user devices may become a key part of safer browsing experiences.
