Emergency alerts. Free and open source software to manage them

Emergency alerts
When a crisis occurs it is necessary to give affected people, and to whom they must respond, a notice that allows them to prepare. In Myself Previous Article I described the characteristics of a special kind of open source software. The alert managers. Now it was time to review some of the tools available.

Emergency alerts. Why use specific software

I had commented in my previous article that it had never occurred to me that programs of this type could be used by private companies. However, if we learn anything from this pandemic, it is that all medium or large organizations should implement them.

The benefits of a good alert manager are:

  • Unique interface to send a message in multiple ways.
  • Minimization the possibility of spreading false or distorted information.
  • Check-in to large numbers of people at the same time.
  • Give one fast answer to unexpected events.
  • Create sense of security and personal protection.
