Services

NSS was founded by engineers whose hobby was to solve technical problems

That philosophy remains until today; in fact we back it up with a larger-than-average staff of experienced engineers that help us to support the solutions that we distribute with greater speed and efficiency, and with fewer errors.

NSS Types of Services are:

Presales Services

After Sales Services

Training Services

Presales & Aftersales Services


NSS technical team works closely with the channel partners to establish project timelines and realistic completion times. For our channel partners we go the extra mile in terms of channel readiness and enablement to ensure that the right product is made available at the right time in the most efficient and cost effective manner.

NSS is aware of the difficulties for both partners and end customers when implementing new information technology systems. Our highly skilled engineers are certified by vendors official training in all the products that NSS distributes, in order to be able to offer qualified product field special services. NSS is able to offer a service to work with the partner and the customer together for a complete project implementation with the following unique methodology:

  • In the beggining, NSS is helping the partner to deliver services to the customer as a part of their training. This ensures optimal implementation and good speed of delivery. This is a quick-start method that provides good results for both the partner and the customer.
  • After one good project implementation, NSS is helping the partner to deliver the project staying behind as a consultant of the partner, safeguarding the project and end-customer investment. This is a necessary stage that provides even better results contributing greatly to the partner morale.
  • The ideal results are provided when the partner delivers the projects independently from NSS. There is a specific training and enablement plan that NSS has designed that is able to make the partner very strong in project complete delivery, independently of the project complexity. This involves an innovative methodology as NSS is not distributing a single product but a portfolio of solutions that integrate to each other.

NSS is adding value to the ecosystem of clients and channel partners by complementing their skills and knowledge in such a manner that they can enhance their customer base, generate more valuable business opportunities and manage complex business opportunities exceeding their own skill and resource capabilities. NSS value adding is also defined by the official training that can be offered to the channel partners. Learning deeply into a new system can be really difficult. NSS can transform good engineers into solution architects in no time. NSS can teach the partner the best practices and demonstrate all the ways to utilize every bit of value out of the products that NSS distributes.

NSS is an Authorized Training Center for several products of different Vendors. Classes are taught mainly in English & Greek language with English documentation. Prices include training materials, vouchers for official vendor certificates when applicable, coffee & lunch during the training procedure. NSS aim is to teach the audience all the skills needed to deploy a solution efficiently and effectively, maximizing the existing investment.

Our technical training team combines a deep knowledge of the products with extensive real world experience of designing, deploying and troubleshooting implementations across the entire range of customer types. All of our courses are taught by systems experts with years of technical support experience and in depth product knowledge so that attendees can not only learn how to configure, but how to avoid common mistakes in system deployments. Most of the training courses include ‘hands on’ exercises. Our training rooms can accommodate up to 6 delegates, allowing for a high level of personalisation and interaction with the trainer bringing the training experience to a really high-level.

By following NSS training courses you can achieve:

  • Greater efficiency in their IT processes, saving hours of admin time per week.
  • Improved performance of products, resulting in less internal helpdesk calls.
  • Reduced need to contact Technical Support with the accompanying time needed for logging and managing cases, conference calls, collecting logs etc.

NSS offices where training is taking place, is very easily accessible using the Metro which is the simplest and quickest way to move around Athens city centre too. Metro is the quickest option from the airport to our office since Agia Marina is the last station on Line 3 (Blue) so coming in from the airport that is the first station, all you need to do is wait for the train to stop to the last station.

If you have some spare time, we will be glad to discuss and organize together with you a private tour to Acropolis museum, Acropolis monument, or any kind of interesting place you like in the centre of Athens. Let us know about it !
