When someone needs help, every second matters.
A safeguarding platform that connects personal safety alerts directly to trained control room operators — a faster, more reliable route to help, wherever someone is.

The app people carry
A calm, simple way to reach help the moment something feels wrong — built to be effortless when it matters most.
ESAF
The response behind it
Established control rooms and the trained operators who staff them — ready to act the moment an alert comes in.
A direct line to help
Alerts reach trained operators in established control rooms — real people who can act, not an automated queue.
The right team, every time
ESAF is aware of local boundaries, so each alert reaches the people responsible for that area.
Privacy built in
Data protection is designed in from the start, with strict limits on how information is accessed and used.
ESAF is developed by Signal One Safe, a UK company building practical technology for personal safety — designed in close partnership with the control rooms and safeguarding teams who use it, so help is never far away.
