I would recommend this solution to others.

I rate IBM Sterling File Gateway a nine out of ten.

The only limitation of this solution is that you have to pay to expand it, other than that it's stable and flexible.

Plan your upgrades very carefully, and go through the documentation.

It's a fairly stable product, but there are always other products on the market.

I would rate this solution a six out of ten.

On a scale from one to ten where one is the worst and ten is the best, I would rate this solution as a ten-out-of-ten. In the past, it seems the whole industry adopted this solution because it was the leader in the field. Whether their whole architecture will be adaptable enough for the cloud is something that needs to be studied further.  

There are solutions like GoAnywhere or Axway where the usability and flexibility is so easy. SFG has a legacy we have to deal with. I know they have pretty big clients and are one of the prime vendors. I'm not talking about the latest version of SFG, I haven't had a chance to look at it. If what they promise is correct, it might be a big improvement. 

I would rate this product a two out of 10. 

I would rate it an eight out of ten. 

Not a ten because  it's a bit complex, not so simple. It's one product but there are many screens.
