Although the Redmond giant has added quite a few new features to Microsoft Edge in the past months, the company is now working on a new security-focused feature dubbed the “Super Duper Secure Mode” (SDSM) for Edge.

The company announced the new security mode via an official post on its Microsoft Browser Vulnerability Research Blog. In the post, lead researcher Jonathan Norman explained that the team is working on a new feature for Edge that “challenges some conventional assumptions held by many in the browser community.”
