Microsoft has a new strategy for bolstering security in its Edge browser. Introducing: the aptly dubbed...

If you’re not familiar, Super Duper Safe Mode (SDSM for short), is a new, experimental Microsoft Edge feature that focuses one of the most perilous weak points in any web browser, Javascript — specifically, a category of Javascript called Just-In-Time (JIT) compilers that are meant reduce web page load times.

In essence, SDSM sacrifices speed for security by disabling JITs and effectively reducing the number of weak points in the Edge browser. It also allows for additional security layers that wouldn’t otherwise be feasible with JITs enabled. Degui Adil / EyeEm/EyeEm/Getty Images

Using SDSM could imbue added safety and convenience to the Edge experience. Theoretically, using SDSM means having a more secure environment for sensitive tasks like banking or transacting crypto. Shutterstock

So how do you get started?

If you use Edge and want to try Super Duper Secure Mode for yourself, you can to do so with a few simple steps. First, you’ll need to download the beta version of Microsoft Edge’s new Insider build. Developer and Canary versions are also available, but stability wise, beta is the way to go.

Once you have the beta version of Edge installed, you can switch Super Duper Secure Mode on by opening up the browser and punching in, “edge://flags/#edge-enable-super-duper-secure-mode” into the address bar. Select the drop down menu and choose “enabled.” Once you have the flag enabled, just restart the browser and Super Duper Secure Mode should be up and running.

Note:

This feature is only available on Windows, so if you’re attempting this on a Mac, you won’t find the feature in your list of experimental flags. Shutterstock

Since the feature is still experimental, there’s a chance you might run into some bugs. You can also expect some web pages to load slower than normal — after all JITs are designed specifically to expedite load times, and in Super Duper Secure Mode, you’re browsing without them. Shutterstock

That being said, a marginally slower load time could be a small price to pay for added security — nay, Super Duper security. Shutterstock
