How to use Super Duper Secure Mode in Microsoft Edge

Unlock maximum security in Microsoft Edge with Super Duper Secure Mode. Easy guide!

Microsoft Edge has an advanced security tool called “Super Duper Secure Mode” that is meant to make the browser safer from different online threats. The launch of this mode in reaction to the growing complexity of cyberattacks and the growing need to protect users’ privacy and data is a big step forward in browser security technology. In this article we will show you how to use Super Duper Secure Mode in Microsoft Edge.

At its core, Super Duper Secure Mode uses a strict and proactive method to fix security holes that bad people often take advantage of. It does this by using a special compiler toolchain to build the browser’s source code with extra security measures built in. This lowers the number of possible attack surfaces and makes the browser more resistant to memory safety flaws like those that are often used in code injection attacks.

This new tool not only makes Microsoft Edge safer, but it also makes browsing safer for everyone. Users can browse the web with more trust when Super Duper Secure Mode is turned on, as they know that their personal information, sensitive data, and online activities are better protected against a wide range of cyber threats.

What is Super Duper Secure Mode (SDSM)?

Super Duper Secure Mode (SDSM) is a new advanced security tool in Microsoft Edge that is meant to make the browser more resistant to different types of cyber threats. It is meant to make the browser much safer by using a special code toolchain to make defences against memory safety flaws stronger.

Traditional web browsers are often vulnerable to attacks that take advantage of memory safety flaws like buffer overflows and use-after-free. As a result, attackers can use these holes to run dangerous software on users’ computers, which could steal data, compromise systems, or cause other problems.

How to use Super Duper Secure Mode in Microsoft Edge

  1. Open Microsoft Edge browser on your device.
  2. Click on the address bar at the top of the browser.
  3. Type the following address: edge://flags#edge-enable-super-duper-secure-mode and press Enter.
  4. Alternatively, you can navigate to the Edge Flags page and search for “Super Duper Secure Mode” using the search box.
  5. Once you find the option, click on the dropdown menu and select “Enabled.”
  6. Finally, restart your Edge browser to apply the changes.

Benefits of Using Super Duper Secure Mode

  • Reduced Attack Surface: By disabling Just-in-Time (JIT) compilation, SDSM eliminates a common target for attackers. JIT compilers can introduce vulnerabilities, and disabling them makes it harder for malicious actors to exploit them.

  • Improved Exploit Mitigation: SDSM enables additional security features like Hardware-enforced Stack Protection and Arbitrary Code Guard (ACG) that further restrict exploit opportunities.
  • Increased Protection for Sensitive Activities: Using SDSM for high-risk tasks like online banking or accessing sensitive information can provide an extra layer of security.

Tips for Maximizing Security with Super Duper Secure Mode

  • Better security: Turning off Just-in-Time (JIT) compilation in SDSM lowers the attack area, which makes it harder for bad people to take advantage of security holes.
  • Performance Decrease: Without JIT, the browser has to process JavaScript code on the fly, which slows things down, especially on websites that use a lot of JavaScript.
  • Pick the correct mode: You can choose between “Balanced” and “Strict” in SDSM. While “Balanced” strikes a good balance between security and speed, “Strict” puts security first and may have a big effect on performance. Start with “Balanced” and make changes based on what you need and how comfortable you are with slowdowns.
  • Use selectively: You might want to only use SDSM for certain high-risk tasks, like banking online or getting to private information. For normal viewing, you could switch back to normal mode.


Should I use Edge Enhanced security?

Go back to the Balanced level if there are too many hurdles. There is a chance that you might want to turn on the switch for For more safety when browsing sites in private mode, always use the “Strict” level of improved security as shown below.

How do I always use secure connections in Microsoft Edge?

In Microsoft Edge, click on Settings and then on More. Go to Settings and then to Privacy, Search, and Services. Make sure that “Enhance your security on the web” is turned on under “Security.” Choose the way you want to browse on this page.

You can find Super Duper Secure Mode in Microsoft Edge as “a browsing mode where the security of your browser takes priority, giving you an extra layer of protection when browsing the web.”
