Secure Messaging Apps


About This Course

Messaging apps have become a key communication tool. We share a large amount of personal and professional messages, pictures, videos and attachments through messaging apps, but rarely question who might have access to this content.

In your work you might want to protect your communication with colleagues, sources, or clients. In your personal life, you might want to protect the pictures you share with your family and friends.

And there are a lot of different messaging apps out there. How do you choose the ones that work for you? From a privacy and digital security perspective, there is no one-size-fits-all solution; it is all about making choices. Start the course and find out what works for you!
