The Defensify Difference
We know security first-hand
With nearly 30 years in law enforcement and a decade of expertise in window film solutions, we have the knowledge and experience to protect those who matter most to you.
Locally-owned and operated
Many security film companies outsource installations to third parties which can cause quality control and scheduling issues. At Defensify, every job is handled in-house by our insured and experienced installers.
Quick turnaround time
Defensify is committed to working quickly to protect what matters most – your people. That’s why we’ve invested in a state-of-the-art cutting table so we can secure your windows quickly and efficiently.
Work around your schedule
To keep disruptions to your workplace to a minimum, our installation team works around-the-clock including nights and weekends.
Unparalleled customer service
From fast and free quotes for any size project to custom tailored packages to maximize security and work within any budget to ensuring every job is completed to perfection, our team is committed to doing right by our clients.
