Pros
None that I can think of. Sangfor is, without a doubt the cheapest company I have ever worked for. All they do is run around trying to get something for nothing.
Cons
Sangfor's business plan is built around the idea of finding a partner/sucker that is willing to assume the costs associated with supporting their products here in the US, including lead-gen, marketing and branding and so on. The 2013 marketing/lead-gen budget was cut from 100k to 60k and in a 10 month period, from January-October we were allowed to attend only two (2), low level trade shows. We had planned on hosting or attending 13 events but that cost money so no way. Here is a prime example of what you can expect from Sangfor: When the VP of International Sales visited the US he slept on the floor at an employees home VS pay for a hotel...and the Hyatt is 250 yards from the office. Do not waste your time unless you enjoy eating fast food and sleeping at Motel 6 when on a business trip.
