"Back in 2021, we upgraded to fiber throughout the fairgrounds. At the time, we had a alternate company doing our IT maintenance and upkeep. A company named EnFocus helped us get everything set up and partnered us with QuantaSi to manage the health and maintenance of the devices. I was very impressed with their professionalism, knowledge and sense of urgency when we had a problem. Over the next two years they helped us troubleshoot problems and worked out all of the kinks of our new network. In May of 2022, our contract with the other company was up. I spoke to Nick Hahaj from QuantaSi about taking over all of our IT needs. They have done an amazing job helping us upgrade obsolete equipment to make our network more efficient. I would recommend QuantaSi to anyone in need of their services. "

-Jeremy B., St Joe County Fair

"I own and operate a boutique HR Consulting firm. I need an MSP to help with all aspects of my IT and Cyber Security. As you can imagine - in HR we have access to a lot of data that needs to be protected to the highest level. We have been with them for about 6 weeks now and I cannot recommend them enough. They have made the transition from my previous MSP so seamless! Any questions or issues are resolved very fast. I knew I had a knowledge gap around Cyber Security and Nick has gone above and beyond to teach me and support me with building the necessary policies so we are mitigating as much risk as possible. This part of my business has kept me up at night over the last year. I am so thankful I found QSI. They seem to have all the bases covered and I feel so much more at ease that we are doing all we can to protect ourselves and our client's data. If you own a business and feel that IT and/or cybersecurity is a concern - you should call Nick and his team right away. They offer a great service and even better support!"
