Exceeding Expectations Every Day


When we are dealing with the safety and security of clients, families, and businesses, we take our services very seriously. We have risen in the ranks of technology and security systems because we have always offered honest input on feedback on what is best for your residential or commercial location. Whatever system or advice we provide to you, you can be assured it will be the exact fit for your location.


With two primary locations in Sikeston and Columbia, Missouri, we are accessible to many businesses and homes in the Missouri areas. We pride ourselves in timely service, and we take that all the way from the providing of the quote, to the execution of our services. If you use us for your business and residential systems, we will always just be a call away.


Safety and Security are nothing to take lightly, as well as knowledge of modern technology systems. All of our staff have received the necessary training and education that they will need to be able to back our services and guarantees. Not only are our employees trained, but yours will be as well after we educate you on using your new system.


The technology industry is always advancing and moving forward, and we always aim to be ahead of the trends. We can guarantee your system will be the most up to date of its kind, and will continue to educate you when new technologies and systems arise.


The reason ESI was started was to provide local Missouri residents with reliable services that could increase the safety and efficiency of their homes and workspaces. We want to see your business succeed, and we want to see your family protected, and this cornerstone is consistent across the board for our services. We aren’t just a technology company; we are a friend.
