What are most required IT/Computer certificates/courses in Saudi companies today?

it depends upon the scope of work , PMP in project management , cisco certifications in network , .NET , Java , Oracle , SAP in deveopment and so on .

It depends on the IT area i.e. Infra structure, communication, software development, DB, ERPs etc. In Saudi and many countries SAP is classified high paid.

 CISCO, Microsoft, PHP are some basics

I fully agree with Mr Mian Muhammad Naeem Jan  

Cisco, Microsoft, VMware, ITIL, PMP, Oracle, SAP.

I think these are the most wanted IT fields in Saudi Arabia. 

CISCO certified courses

CCNA

cisco certified internet expert (ccie)

• ITIL : Information Technology Infrastructure Library
• CISSP : Certified Information Systems Security Professional
• A+ and MSCE Microsoft Certified Solutions Expert

Technical Support Engineer

VCP5 is hot these days.

ERP (SAP, Oracle, Dynamics): absolutely hot and required in the job market today. However, jobs require you to know functional modules as well as technical modules. As an IT guy, you only care about technical such as SAP BASIS.

CCNP, CCIE: are required but they are not hot anymore due to the massive explosion of CCNPers and the increased number of CCIEers. If you want to focus on internetworking, then these are for you.

MCSE, MCITP: are still required but MS certified individuals are terribly huge in number so the job demand is reduced. If you want to get hired quickly, then these are for you.
