Reducing the Business Cost of Network Failure with a Managed Services Provider

About Us

Our company's founder Mr. Cumhur Altıntaş, has came to a passion in new technologies and IT in early ages of computers back in 1988. The one thing that is noticeable in IT services is that everyone needs a friend that knows how to give technological advices and sometimes fix things.
So, aware of this point that not everyone have this type of friends to turn into in the matter of technological problems, he decided to found a company to provide IT services in a friendly environment that everyone can benefit.
At first we focused on providing computer parts and services by the name of "Notebook Pazarı" in 2001. Later, in 2012 we changed the company's name to "Cumbaba Bilişim Hizmetleri. LTD." and ONSERVIS became a brand name for IT Services provided by this company.
Our main goal is to present Reliable, Clear and Cost-Efficient solutions based on our customers needs.
