Sentry Global Technology has been my VoIP provider for years.

We have been with Sentry Global for a number of years. They are very professional, quick to respond to our needs. We can always depend on them to get us through a crisis if one should and has occurred. They were with us every step of the way to see us though. I would highly recommend them for all your technology needs.

Great job managing my VOIP IT services!

The guys at Sentry Global Technologies have done a great job of helping me get my new firewall installed. They provide computer, server and network support for my small office of about 20 people. We have a VPN and 3 servers that all need to be managed and these guys do a great job. They also help me with backing up all my servers. Great service and reliable support.

Sunnyland Furniture in north Dallas is a family-owned retailer of outdoor and patio furniture which has been serving customers for decades. They are open seven days a week, including evenings and most holidays, and depend on their technology platform for email, inventory, sales, payments (including credit cards), accounting, delivery scheduling and a variety of other tasks.

Once engaged, Sentry re-engineered and updated their network to bring it into compliance with Microsoft best practices, increasing uptime to 99.6% from 78% in less than ninety days. We also redesigned their wireless network environment, which hadn’t worked properly, so that it now delivers 100% uptime. Please take a moment to hear the son of the founder, who runs day-to-day operations at Sunnyland, talk about their experience with Sentry and our managed network services!
