3Si Tracker Mobile

Founded in 1971, 3SI is a market leader in pioneering advanced security solutions for asset protection and recovery. We are always ahead of the curve starting with the commercialization of dye and ink staining, to our ongoing development in GPS tracking and beyond.

3SI and Wren Solutions merged in June 2023. Leveraging a combined 90 years of experience, we are leaders in security technology solutions that deliver proven people, asset, and loss protection. By enabling a robust defense against the rapid rise of violent robbery and organized retail crime afflicting our communities, 3SI and Wren help customers prevent and detect crime while safeguarding their staff and patrons at more than 75,000 locations worldwide.


Our combined solutions include asset tracking, video analytics, and seamless data transmission during criminal incidents, giving law enforcement a crucial edge in apprehension, asset recovery, and convicting criminals. Our solutions make a real impact and have assisted law enforcement with over 19,000 arrests.

CovertTrack, a 3SI Company, supports more than 3,000 federal, state, county, and municipal agencies with tracking, tactical, and surveillance solutions, further aiding their efforts to proactively combat crime within their jurisdictions, leading to immeasurable arrests. Recognizing the varying needs across law enforcement branches, we’ve customized solutions for them.

Our vision is to create a safer world.

Law Enforcement
Our solutions supply actionable, data-driven intelligence to over 10,200 law enforcement agencies, sending this information automatically to their dispatch centers and officers for prompt responses to financial and retail crimes. The trust these agencies place in our notifications isn’t coincidental; it’s cultivated through the efforts and training provided by our Law Enforcement Division (LED). Our LED comprises 24 dedicated, retired law enforcement professionals with unparalleled expertise.

24/7 Support
Crime is not a 9-to-5 problem, and successful crime solutions need to be available round-the-clock. To support our solutions, our 24/7/365 Tracking Support Center (TSC), based in the USA, is on the job.

Every crime event involving a 3SI solution is logged and managed by the TSC, and we support local dispatchers and law enforcement every step of the way during an active track. The same 24/7 support services are available to our customers because we know that you need support when you need it.

Product Installation, Maintenance and Training
3SI’s dedicated Field Service Organization provides industry leading installation, maintenance and training. Our products support the do-it-yourself as well for customers who prefer to handle on their own. Training videos and guides are available at our Customer Portal.
