How to use Super Duper Secure Mode in Microsoft Edge

In its pursuit to build something that has the potential to change the modern exploit landscape and significantly raise the cost of exploitation for attackers, Microsoft rolled out Super Duper Secure Mode in Edge. It intends to increase the secure browsing experience of users.

Super Duper Secure Mode in Microsoft Edge

The main objective behind introducing Super Duper Secure Mode in Microsoft Edge is to prevent cybercriminals from accessing and exploiting the bugs in the browser. Apart from this, the Edge browser will use the following advanced security features to ensure safety while browsing the Internet.

• Window’s Arbitrary Code Guard (ACG)
• Control Flow Guard (CFG)
• Intel’s Control-flow Enforcement Technology (CET)

Super Duper Secure Mode disables JIT (TurboFan/Sparkplug) and enables CET (Exploit mitigation from Intel). JIT, also known as Just-in-Time is a performance technology introduced in browsers to speed up specific tasks in JavaScript. Traditionally, browser developers were using it because users want their browsers to be fast. However, the supply of a regular stream of bugs requiring frequent security updates made this technology somewhat less useful.

Disabling the JIT thus makes sense as it can result in a reduction of the attack surface and improve user security, significantly.

How to enable Super Duper Secure Mode in Microsoft Edge?

To enable Super Duper Secure Mode in Microsoft Edge is simple; you need to enable an Edge Flag.

1. Launch the Edge browser.
2. Click inside the address bar.
3. Type the following edge://flags#edge-enable-super-duper-secure-mode and hit Enter.
4. Alternatively, open the ESge Flags page and search for Super Duper Secure Mode using the search flags box.
5. Enable the mode.
6. Restart Edge.

Launch Microsoft Edge browser. Currently, the feature is available in Edge Canary, Dev, and Beta. So, make sure your browser is updated to the latest version.

When the browser opens, click inside the address bar, type the following and hit the Enter key – edge://flags

Next, n the Search Flags box just below the address bar – enter the following text and hit the Enter key – #edge-enable-super-duper-secure-mode.

Next, hit the drop-down menu next to the above flag and change it from Default state to the Enabled state.

When done, restart the browser to allow the changes to take effect.

How to enable Super Duper Secure Mode using Edge settings

In recent Edge versions, you can also follow this procedure using Edge settings:

1. Launch Microsoft Edge browser
2. Open edge://settings/privacy in your address bar
3. Scroll down and toggle On the switch against Enhance your security on the web or Enable security mitigations for a more secure browser experience
4. You can select any one of the options:
   • Balanced mode will only affect websites you don’t visit often.
   • Strict mode will affect all websites, resulting in potential slowdowns.
5. You can also add Exceptions.
6. Restart Edge.

Does Microsoft Edge have security?

Microsoft Edge is more secure than Google Chrome for your business on Windows 10. It has powerful, built-in defenses against phishing and malware and natively supports hardware isolation on Windows 10.

Is Edge better than Chrome?

Both browsers are very fast. Chrome beats Edge in the Kraken and Jetstream benchmarks by a very narrow margin. Edge is however less of a resource hog.

Hope it helps!
