Since 1997, Harmony Security Products has been dedicated to designing and manufacturing innovative security solutions for residential, commercial, and institutional applications. Our focus is on protecting the most vulnerable points of a building—doors, windows, and other egress locations—through products that provide exceptional security without compromising safe and efficient exit when needed.

At Harmony, we understand that effective security must strike a balance between protection and accessibility. That’s why our products are engineered to help prevent forced entry while maintaining compliance with egress and life-safety requirements.

Harmony Security Products was founded by Daniel T. Guthrie, whose vision and commitment to quality established the company as a trusted name in the security industry. In 2021, Dan passed the baton to the team at IWM International, marking the beginning of an exciting new chapter in the company’s history.

Today, the combination of Harmony’s experienced craftsmen and product expertise with IWM International’s engineering, manufacturing, and operational resources provides a strong foundation for continued growth and innovation. Together, we remain committed to delivering high-quality security solutions that protect people, property, and peace of mind.

As we look to the future, our mission remains unchanged: to develop reliable, practical security products that help our customers secure their homes and facilities without sacrificing safety, functionality, or ease of use.
