During the last few months we had to deal with a very slow internet connectivity. While we had 2 internet lines, we couldn’t make it work in an optimized manner, thus we were struggling in our day-to-day activities. Giant stride managed to offer us a solution that actually works, in a reasonable cost. At last, we have the Internet connection speed we need! It is amazing how fast their support team is and able to solve any matter as soon as possible.

Cezary Szandecki,

Our cooperation with Giant Stride started in 2008 and we have a great professional relationship until today. Whenever we need their support, they answer their phone live, or they return our calls within 60 minutes. This is a great deal to me, because I know that I will be able to communicate with them on time. Whatever Giant Stride have proposed to us, it is accurate and within our budget and quality standards.

The latest project which started on 10/2016, was related to our IT security infrastructure. They installed, configured and trained us on firewall devices (Sophos) and endpoint products (Sophos Central). At the same time, they migrated our on-premise Exchange installation to the Office 365 cloud service. The whole project has been completed on time and on budget.

Our experience with Giant Stride is very good! They start working on critical issues immediately, while they respond on issues of a medium importance quite fast and in a reasonable time if it needs further research. To be honest, their response time is in sync with our needs! I am not aware if the lack of computer problems is the result of their daily monitoring, or the result of the upgrade project they implemented, when we started. Well, we rarely have problems and if something happens, it is usually due to the slow internet speeds in our area. I would definitely recommend them!

Thomas Doxiadis, Doxiadis+

Our experience with Giant Stride is exceptional! Before they took us over we had recurring problems with our server and a number of issues with our emails. Giant Stride made these 2 significant changes without us even realizing! Practically, when we started our collaboration, Giant Stride optimized the system to our needs and the problems were resolved right away! It is hard to believe so, but that’s how it works!

Since our company operates on a 24h basis and the use of computers and the internet is critical, the daily maintenance of our systems is the most important thing. We realized that WHATEVER happens, Giant Stride has it covered! Moreover, they respond to our calls live, whatever the problem may be.

Ioanna Basakou, Aries Marine Insurance Brokers

Before we start working with Giant Stride, we had many doubts about the support model they are using. We didn’t know if that would be a right fit for us. Fast forward one year later, I am able to say that their response time is quite fast (usually less than an hour) and when we ask to resolve an issue, they manage to get it right from the first time.  Today, we have absolutely no issues with our computer network and that’s why we always recommend Giant Stride to our business partners and customers.
