Enable Microsoft Edge Super Duper Secure Mode Easily

This post shows students and new users how to easily enable the new Microsoft Edge Super Duper Secure Mode (SDSM), which has just been released in the latest Canary build.

If you try to do this in the current stable version of the Microsoft Edge browser, you’ll be unsuccessful because it’s not there yet.

This feature works by disabling Just-In-Time Compilation (JIT) and enabling new security mitigation, which Microsoft claims are among the most common ways attackers exploit. The JIT feature is meant to render sites faster, but it’s also commonly used as an exploit in the browser.

The SDSM improves security by turning off JIT, which may impact performance. So you gain security but lose on performance; not sure how much performance since this is a beta, and it may likely improve over time. SDSM disables JIT and enables new security mitigations to provide a more secure browsing experience.

If you want to test SDSM today, you’ll have to download the Canary version of Edge, and the steps below will show you how to do that.

To get started with enabling Microsoft Edge Super Duper Secure Mode, follow the steps below:
