IE11 End Date Myth-Busted: Smooth Migration to Edge IE Mode with Browsium

Posted by: Gino Tags: Posted date:

Don’t Panic!

The timeline for the IE11 end date can be confusing. Microsoft tried to be clear, but the variety of services used by the browser just made it complicated. Add to that the product naming schemes, and it’s no wonder customers call us in a panic believing Internet Explorer 11 will be unsupported, like, tomorrow.

It’s not. What’s happening is that Office 365 is ending support for Internet Explorer 11. Microsoft will continue to support the Internet Explorer 11 product itself until next summer.

For customers that have applications still built on IE11, don’t panic. Our soon to be released client 4.9 (at no charge to current M&S agreement holders) will allow for a smooth migration to Edge IE Mode. After all, we’ve been doing this kind of thing for more than a decade, so we know how the process works. We know what it takes for an organization to migrate from one browser version to another and how much more it takes to migrate from one browser platform to another seamlessly.

Edge IE Mode

Microsoft Edge is entirely different from IE – from the ground up. Mission critical application platforms like ActiveX aren’t supported in Edge (or any other leading browsers). Hence IE Mode in Edge.

While IE11 support isn’t ending tomorrow for your business apps, the clock is ticking. The sooner we start together, the better to ensure a smooth transition for your enterprise
Decades of dependence on unsupported tech in critical industries like logistics and manufacturing are about to collide with a wall of incompatibility.

Browsium can help keep them operational where appropriate and support the path to modernized platforms when that makes the proper business sense.We give you control over when to make a move and how to do it. While IE11 support isn’t ending tomorrow for your business apps, the clock is ticking. The sooner we start together, the better to ensure a smooth transition for your enterprise.


No, not a silver alert, but an alert that support/security updates – for yet another ActiveX app – will be ending in October for IE based Silverlight. For most everyone on the consumer side of things, this will not be an earth-shattering event; Silverlight and IE are mostly just an asterisk for home computing at this point. Enterprise IT, on the other hand, is an altogether different story. Millions of lines of code written for internal applications are still dependent on Silverlight. This leaves ITOM with but a few options: The continued use of a plug in that will no longer have security updates (risky, to say the least), rewrite/modernize the code (expensive and time consuming), or create a secure “locked down” environment that will only allow Silverlight to launch for trusted internal applications (as far as the wider internet is concerned, there is no Silverlight in your environment).

If you are reading this Newsletter, you know where this is going… Discover: Proton Remediate: Ion… If you already have Ion in your environment, we’d be happy to help with a Silverlight remediation.


As always, thank you for your support, and let me know if there is anything that you would like to be discussed as a topic.

As far as the wider internet is concerned [when using Ion], Silverlight is not in your environment
