At Defentac®, we are passionate about empowering people to protect themselves and their loved ones. Our state-of-the-art laser sights and lights give you the advantage you need to stay safe in an uncertain world.
Our Story

Defentac® was founded in 2022 by John Smith, a former police officer who believed that everyone has the right to feel secure. After 20 years on the force, John saw firsthand how having the proper tools and training could mean the difference between life and death in dangerous situations.
When John left the force, he poured his life savings into creating Defentac® – an organization dedicated to giving regular citizens access to the same elite security products used by law enforcement and military personnel. We research, develop, and rigorously test our products to ensure they meet the highest standards for accuracy, visibility, durability, and ergonomics.
Over the past few years, Defentac® has grown from a small startup into a leading designer and manufacturer of laser sights, lights, and self-defense products. But our mission remains the same: to empower people to protect themselves, their homes, and their loved ones.
