When active, Super Duper Secure Mode also enables control-flow enforcement technology (CET), a hardware-based exploit mitigation from Intel, and arbitrary code guard (ACG). Both security features were previously set to off by default, for performance-related reasons.
“Performance and complexity often come at a cost, and often we bear this cost in the form of security bugs and subsequent patches,” wrote Norman when the new mode was first announced.
“This reduction in attack surface kills half of the bugs we see in exploits and every remaining bug becomes more difficult to exploit. To put it another way, we lower costs for users but increase costs for attackers.”
Super Duper Secure Mode can be switched on at the foot of the Privacy tab in the Edge settings menu.
