On August 17, 2021, Microsoft will begin to sunset its Internet Explorer (IE) web browser as it plans to discontinue the service altogether by 2022. This is incredibly important for all HSIN users, as starting in August, IE will offer a degraded experience, limiting the functionalities of many HSIN platform tools and services.

Therefore, the HSIN program will no longer support IE 11 or any previous IE browser as a recommended platform. For all your future HSIN efforts, we highly recommend moving to Microsoft Edge or another supported browser. The following table summarizes the support levels of typically used web browsers.If you have any questions, please contact HSIN at HSIN@hq.dhs.gov or you may reach directly to your HSIN Mission Advocate for assistance.
