Protecting the quality of life on Long Island
Electronix Systems is more than just a company; it's a legacy built on trust, reliability, and a steadfast commitment to protecting the quality of life on Long Island. Since our inception in 1971, we have proudly served the Long Island community, evolving from a small enterprise specializing in home alarms and antenna systems to a comprehensive security solutions provider. Our founder, Fred Leonardo, recognized the growing need for reliable security systems and instilled in us a dedication to exceeding customer expectations. This dedication has been the cornerstone of our success, allowing us to grow into a full-fledged security company with over 85 dedicated employees who are all passionate about providing exceptional service.
In 2010, Electronix Systems transitioned into an ESOP (Employee Stock Ownership Plan), a testament to our belief in the power of shared ownership and collective success. As employee-owners, each member of our team shares a vested interest in the company's growth and well-being, fostering a culture of accountability, innovation, and unwavering commitment to our clients.
