Dubai Airports Authority, Saudi Airlines, etc.. there are some more eventually in MENA region. contact Hisham Malak (sales director), Muhammad Arif (Solution and presales) they should be able to get you information you need. I can't disclose the use cases since we had NDA. However they have been using most of service management, clarity, service assurance all the products. if you want to even look at service pricing and budgeting Saudi Airlines should be ideal.
Contact your local CA account manager they should be able to get you in touch with MENA team. that would be the best channel of communication. Good Luck
P.S. we are going to have reunion with school friends in tucepi for 2 weeks in august. really excited
