Whether a disaster alert, an urgent notice or a security message – in some situations, all employees of a company must be reached quickly and unambiguously. A smart solution for this is silent alerting with IDERI note. Although it does not require an alarming sound, it reaches your employees in a direct and reliable way by notifying them directly on their desktop.


Originally developed in cooperation with a company working with hazardous materials, today customers from a wide range of industries make use of our Silent Alarm software.

Be optimally secured in case of doubt with IDERI note

A silent alarm expands the company’s internal communication options by providing a direct and effective line to all employees. In dangerous situations, such as a fire, a disaster or a health risk, IDERI note notifies all addressees quickly and clearly. In an absolute emergency, you trigger a silent alert with a silent alert button, a foot switch or a specific key combination on your keyboard.

As a result, an unmistakable message appears on your employees’ desktop computers, underlining the urgency and explosiveness of the situation.

Simple messages on topics such as data protection, IT or personnel can be communicated to all or selected employees via freely configurable notifications that you can configure in the Silent Alarm software.

Silent alarm - versatile application and design options

With the help of the Silent Alarm software you can reach the right employees with the right content at the right time. In addition to the content of your message, you can also freely design the display format on the desktop of your addressees.

While pop up windows are ideal for urgent messages, a silent alert is created when the Silent Alarm button is triggered. If a message concerns only a defined selection of employees, you can implement this thanks to an automatic integration into Active Directory.

Furthermore, IDERI note allows you to send a silent alarm not only immediately, but also at a defined time. Last but not least, the IDERI note silent alarm software has a receipt and read confirmation function, which you can use to ensure that the silent alarm has actually been acknowledged by all addressees.

Universal and uncomplicated - a silent alarm for your company

IDERI note has a number of special features designed to make the silent alarm software as open as possible. For example, the basic principle of the silent alarm also works in offline mode and can be linked to employees’ mobile devices to achieve an additional read guarantee. In addition, IDERI note is compatible with many established in-house systems and already gets by with low system requirements. We have built all these features into our software solution so that as many companies as possible can benefit from the advantages of the silent alarm. After all, flawless and direct communication within a company is worth its weight in gold – as the last 15 years of companies using our silent alarm have shown.


With IDERI note’s silent alarm, you can take your internal corporate communication to a new level and create the necessary infrastructure for the worst-case scenario.
