How to Secure Microsoft Exchange Server In Post-TMG World

Introduction - How to Secure Microsoft Exchange Server In Post-TMG World

For many organizations, Microsoft’s Threat Management Gateway was a critical reverse-proxy security solution for Microsoft Exchange and SharePoint publishing. TMG provided a number of security benefits for Microsoft applications including:

  • Application security
  • Network security
  • Authentication proxy
  • Secure remote access

The Microsoft announcement of TMG’s end-of-sale in 2012 and the end-of-support in 2015 left organizations without a long-term solution for securing their existing Exchange and SharePoint deployments.
