Richard Hicks' Forefront TMG Blog

Since Microsoft formally announced the end of life for the venerable Forefront TMG 2010 firewall, the most common question I hear is “What should I replace my Forefront TMG firewall with?” It’s an excellent question, and one that I can’t really answer for you definitively. Since Microsoft has elected to leave this space entirely, you’ll obviously be replacing it with a solution from another vendor. But which one? Well, the answer is “it depends”. There are many excellent firewalls, web proxies, and secure web gateways on the market today. So-called “Next Generation Firewalls” are gaining in popularity as well, and provide some interesting capabilities a security administrator can leverage to provide increased protection for their corporate networks. Which one to choose depends on many factors, and will vary greatly depending on your deployment scenario. My suggestion when evaluating potential replacements for your Forefront TMG 2010 firewall is to take a look at your current configuration, review your corporate security policy to determine network security requirements, then begin researching products that include the features you need. If you take a look at the latest Gartner Magic Quadrant for Secure Web Gateways or Next Generation Firewalls and choose a product in the leaders or challengers quadrants you will probably be satisfied. Regardless which solution you choose, demand a proof-of-concept or insist on an evaluation period with which you can return the product for a full refund if it doesn’t meet your needs or expectations. Be open-minded during the process, as you’re not likely to have the comfort level with the new solution as you do with your existing Forefront TMG 2010 firewall. If you are using your Forefront TMG 2010 firewall as a dedicated remote access solution, I would encourage you to look closely at Windows Server 2012 remote access VPN and especially DirectAccess.

Keep in mind that although Microsoft has announced the end of life for Forefront TMG 2010, it will still be supported for many years to come. You will have full feature functionality until the end of 2015, and the product will be supported in some fashion until early 2020 so there’s no need to rush. Perhaps the best replacement for Forefront TMG 2010 hasn’t even been created yet!
