More reliable web defense. Browse the web with more reliable protection thanks to the rewritten Microsoft Defender SmartScreen library for Microsoft Edge on Windows, Mac, and Linux. The new SmartScreen library was first made available on Windows and Mac, and now makes its debut on Linux with Microsoft Edge version 108. Microsoft Edge version 108 also brings new product optimizations (that is, better proxy handling) and bug fixes by having the SmartScreen library leverage Microsoft Edge’s built-in network stack.
