It's no secret that Internet Explorer has always been criticized for its poor security, so with the Edge web browser (previously known as Spartan), Microsoft is trying to tackle this problem more effectively and make sure that users consider it at least as good as Chrome and Firefox. In a blog post, Microsoft details the security enhancements available in Edge, pointing out that most of the changes it made to the new browser make it much more secure than Internet Explorer. There is more protection against trickery, app containers are used as the sandbox mechanism, and protection against memory corruption is better. Old, insecure plugin interfaces are not supported at all: VML, VBScript, Toolbars, BHOs, and ActiveX are all nuked from the orbit.
