THE TRUTH
ABOUT TMG
TMG is still available
Are your existing TMG servers still working?
You can still buy TMG appliances
You may still have TMG licenses in your EA/SA
Dont rip and replace without a good reason
If you have a reason, dont hesitate to replace
Other features
Other applications
Redundancy
Monitoring and maintenance
No longer sold is not a good reason
Was TMG ever truly necessary?
