A Safety Infrastructure, Not an App: Why Sentinel Shield Was Built Differently

Most school safety tools fail for the same reason:
they lead with software before authority, consent, or governance are settled.

Sentinel Shield was designed to avoid that failure mode entirely.

Developed by Sound Sentinel Corporation, Sentinel Shield is not a bolt-on app.
It is standalone safety infrastructure, engineered to survive union review, legal scrutiny, and real-world use before it ever asks for trust.
