Microsoft has published security information on it's new "Edge" browser, which it claims is considerably safer.
When looking at all the ways a user's browser could be attacked, you can see why the list in its blog is quite long.
Using it's new Microsoft EdgeHTML rendering engine, the browser integrates with Bing Webmaster Tools to report directly over fraudulent certificates.

Here's something that caught my eye from the blog post.

So to make browsers safer against attacks, and just more reliable, it is important to create an extension model that is safer, by sharing less state between the browser itself and the extensions. Thus Microsoft Edge provides no support for VML, VB Script, Toolbars, BHOs, or ActiveX. The need for such extensions is significantly reduced by the rich capabilities of HTML5, and using HTML5 results in sites that are interoperable across browsers.

To enable extensibility beyond what is provided by HTML5, we are working on plans for a modern, HTML/JS-based extension model. We look forward to sharing more details on these plans, including guidance on migrating your scenarios from ActiveX controls to modern standards and extensions in the coming months.

There's quite a lot more in there so it's worth reading in full.
