Microsoft has quietly added a 'Super Duper Secure Mode' to the Microsoft Edge web browser, a new feature that brings security improvements without significant performance losses.
Users can enable Super Duper Secure Mode after upgrading Edge to stable version 96.0.1054.29 or later, and they can toggle between Balanced and Strict modes for different levels of security increase.
Microsoft describes Super Duper Secure Mode as "a browsing mode in Microsoft Edge where the security of your browser takes priority, providing you an extra layer of protection when browsing the web."
"We quietly released Super Duper Secure Mode to stable," said Johnathan Norman, Microsoft Edge Vulnerability Research Lead. "Balanced learns what sites you use often and trusts those, strict is well. strict :) Users can now add their own exceptions."
When toggled on, Super Duper Secure Mode disables JIT and enables Intel's Control-flow Enforcement Technology, a hardware-based exploit mitigation that provides a more secure browsing experience.
In the future, Microsoft aims to include support for Arbitrary Code Guard in Super Duper Secure Mode, another security mitigation that would block attackers from loading malicious code into memory, a known technique used by most web browser exploits.
