What is super secure mode in Microsoft Edge web browser?
Microsoft’s Edge web browser is already very secure, which has a lot to do with the fact that Edge is built on the same Chromium codebase that powers Google Chrome. With today’s advanced threats, a browser can never be too secure. Enter Edge’s new super secure mode.
What is super secure mode? This is an experimental new feature that disables one of the most frequently attacked browser components.
The introduction of a JIT compiler has brought significant performance gains. Instead of downloading mountains of complex code from a web app and then by processing it, JIT allows a browser to process the code as downloaded.
Complex pages can load up to twice as fast with JIT. The downside is that cybercriminals have repeatedly turned this speed boost into an opportunity to launch attacks.
Malwarebytes security experts note that over 50% of all “in the wild” attacks on Chrome take advantage of JIT bugs. This isn’t too surprising given that just under half of all publicly disclosed Chrome vulnerabilities are related to the JIT compiler.
Ultimately, that leads us to Super Duper Secure mode. Disable the most frequently attacked and possibly the most buggy part of the browser and it becomes much, much harder to attack Microsoft Edge users.
The web pages won’t be ready for use as quickly as they used to be, but that’s not as bad as it sounds. When it comes to processing web pages, you’re talking about milliseconds. According to Microsoft, most users who test Super Duper Secure mode rarely notice a major difference.
It also provides security benefits beyond simply neutralizing a common attack vector. Closing the JIT compiler allows Edge to take advantage of Windows 10’s arbitrary code protection and Intel’s Contro-flow app technology.
These features allow Edge to thwart even more attacks. Considering the relatively low “cost” of this protection, there is every reason to try Super Duper Secure.
So how do you try it?
First of all, you need to install one of the Edge browser preview channels – Beta, Dev or Canary. Then you will need to copy and paste this weird text into the address bar: edge: // flags / # edge-enable-super-duper-secure-mode. Set it to on, restart Edge, and browse as you normally would.
