Displaying contact data

We help you to encrypt access to sensitive data, protect your mobile devices proactively against continual increases in cyber risks and repel attacks effectively – before serious damage is done.

App Management

Searching for contacts

Colleagues can be found by name, company name, e-mail address, or telephone number. For internal contacts, the line manager is also displayed in the contact details – a helpful feature if the desired contact cannot be reached.

More than just a mobile address book

All of your business contacts are always up to date and in one place on your mobile device – with EBF Contacts. But the app is much more than just an address book on iOS, iPadOS, and Android devices that regularly synchronizes with the Global Address List and/or your CRM system. Features like automated caller ID improve availability, productivity, and communication among your employees – offering you a distinct competitive advantage in an era of hybrid and mobile work.

Which data sources can be connected?

To utilize EBF Contacts’ functions, the app must synchronize contacts from data sources. Of course, it is also possible to connect multiple data sources.

Hosting in EBF Cloud

EBF Contacts makes it easy to connect additional sources

Connecting additional data sources, such as Salesforce, Active Directory, or others, is also possible. To do this, data must be exported in CSV or JSON format and compiled into a ZIP archive. To maintain current contact data within the app, it is essential to ensure the information contained in the ZIP archive is always up to date. This process can be automated by using a PowerShell script, for instance.

What EBF Contacts offers

Better accessibility and networking

With EBF Contacts, your employees can carry all their professional contacts in their pocket, accessible at any time.

Should a contact be unavailable, an alternative contact within the organization can be displayed with just one click.

Reduction/identification of
