Company
Twenty years of learning how to get this right
FireShield builds automated wildfire defense systems for homes in 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 are investing back into research and development of new lines of products that are easy to install by average contractor, while keeping the price on the lower end of spectrum.
Who we are
Specialists in one problem
FireShield does one thing: keep a house standing through a wildfire. We design, build, install and service automated defense systems for homes in Southern California, and we do all of it ourselves — the controller, the plumbing, the cloud backend, the fire-data ingestion and the app — because a system whose brain lives on someone else’s platform is not a system you control.
Wildfire, by comparison, is still largely discussed in zones and colors. A house is in a tier. A map is red. That tells a homeowner almost nothing about their house, and it tells an insurer little enough that the market’s recent answer in California has often been to stop writing policies.
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 mature 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 comes out of the conviction that the earthquake profession’s approach transfers: 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 the departure. The industry produces maps and scores. FireShield produces water on a roof.
The story
From a sprinkler on a roof to a hazard model
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 discipline is not really about concrete. It is about acting sensibly under uncertainty.
2006
The first wildfire hardware
Work begins on exterior wetting hardware for houses in fire country — sprinklers, plumbing, control. The early versions are what early versions always are: they prove the physics and fail at everything around it. Pressure is never what the drawing assumed. Controllers die in the heat. The mains go down exactly when the system is needed.
2017
Solid-state, and connected
The controller settles into its present form — a solid-state industrial device with no fan and no general-purpose computer to boot, 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
Risk, protected
One system that watches every fire feed, calculates the hazard for the individual property, and acts on it — a configurable controller, water from wherever there is water, and a per-property hazard model connected directly to the valves.
The team
Engineers, installers, and the people who answer the phone
FireShield is a Southern California company. The people who design the system, the crews who install it and the people who pick up when you call are in the same place as the houses they protect — which is why a service visit in a canyon takes an afternoon rather than a scheduling negotiation.

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 scripts from other companies are not merely denied storage — they are not loaded 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. That is a real commitment, not a statement of intent.
