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 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.
