Email security for Outlook

strong encryption of emails and files

Every day your business exchanges a wealth of data with customers, suppliers and partners. A big part of this communication takes place via email and Outlook and is constructed in your Office applications.

However, often the information is highly confidential or captured in files that are simply too big to send via email. So what happens then?

There are many different ways to get around this problem but our advice is to use the tools you already have!

  • secure and share confidential emails and files without size restrictions
  • completely ad hoc via your regular email directly from your familiar Outlook interface.

By solving these known problems in email Cryptshare provides the fastest and most simple solution.
