Company
Twenty years of building wildfire protection
FireShield builds automated wildfire defense systems for homes in the United States and abroad. The hardware has been in development since 2006, and almost everything in the current product exists because an earlier version of it was not good enough.
Our goal and commitment is to make wildfire protection affordable and accessible to everyone. We put our earnings back into research and development of new products that any contractor can install easily, while keeping prices low.
Who we are
We focus on one thing: wildfire
FireShield does one thing: keep a house standing through a wildfire. We design, build, install and service automated defense systems for homes across the United States, and we do all of it ourselves — the controller, the plumbing, our online servers, the system that collects fire data, and the app — because if a system depends on another company’s platform, you are not fully in control of it.
Wildfire risk is still mostly described with broad zones and color-coded maps. That tells a homeowner almost nothing about their own house, and it tells insurers so little that many have stopped writing policies in California.
Our founder, Dr. David Hosseini, holds a PhD in earthquake engineering and probabilistic seismic hazard analysis. His career has been spent on a single question in different forms: what is the chance that this building is hit by something it cannot take, and what is it worth doing about it now?
In earthquake engineering, that question has a well-established answer. Hazard is calculated probabilistically for a specific address, combined with how a specific structure fails, and turned into decisions — what to build, what to strengthen, what to insure and at what price. He has worked across all of it: the engineering, the risk modeling, and the insurance side where those models decide what a policy costs and whether one is offered at all.
FireShield started from the belief that the earthquake approach works for wildfire too: calculate the hazard for the individual property, account honestly for how it arrives — fuel, terrain, wind, embers — and connect the result to something physical that acts. That last part is what makes us different. Others produce maps and risk scores. FireShield puts water on your roof.
The story
From roof sprinklers to property risk modeling
1999
Engineering, and the question behind it
Our founder’s work in earthquake engineering begins. The work is seismic: how a building behaves when the ground moves, how likely that motion is, and what it is worth spending to change the outcome. The field is less about concrete and more about making good decisions when the future is uncertain.
2006
The first wildfire hardware
Work begins on exterior wetting hardware for houses in fire country — sprinklers, plumbing, control. The early versions showed the idea worked but had many practical problems. Water pressure was lower than planned, controllers failed in the heat, and city water went out exactly when it was needed.
2017
Solid-state, and connected
The controller reaches its current design — a solid-state industrial device with no fan and no computer that has to start up, because the two parts most likely to fail in a wildfire are a cooling fan and an operating system. Wi-Fi, cellular and satellite, because a wildfire takes the power and the phone network together.
Today
Measuring risk and protecting homes
One system that tracks every fire data source, calculates the risk for each property, and acts on it — an adjustable controller, water from any available source, and a risk model for each property connected directly to the valves.
The team
Engineers, installers, and the people who answer the phone
FireShield is headquartered in Los Angeles and serves homeowners in every state. The people who design the system and the people who pick up when you call are one team, and here in Southern California our crews can usually get to a home in a canyon the same day instead of making you wait.
Contact
Tell us about your property
Every system is designed for the specific house: its roofline, its water supply, how the wind runs through the street. The first step is a conversation, and sometimes it ends with us saying you do not need us.

Privacy
What this site collects, and when
Analytics and advertising tools from other companies do not load at all unless you opt in, and you can change your mind at any time from the footer. We count visits to each page on our own servers so we can see which pages are read. If you allow analytics, we also measure how our pages are used — device and screen size, which sections are viewed and for how long, and what is clicked — to make them better.
When you submit a form, we receive what you typed so we can reply to you. We do not sell or share personal information; the “Do Not Sell or Share” link in the footer records that preference regardless.
A FireShield system reports its own operating data — pressure, flow, valve positions, connectivity, battery — so the system can be monitored and serviced. Contract customers: the detail is in your agreement.
Accessibility
Built to be usable
This site is built to WCAG 2.1 AA as a working standard: keyboard navigation throughout, visible focus outlines, a skip link, semantic landmarks, labeled images and form fields, and respect for a reduced-motion preference — animation is skipped rather than shortened if you have asked your system for less of it.
If something here is difficult to use with the tools you rely on, tell us and we will fix it: support@fireshieldwildfire.com. We mean it.
