How to secure E-mail attachments in iOS devices?
Corporate E-mails often contain confidential organization data as attachments, which must be accessible to the users while preventing any type of unauthorized access. It is also expected that these attachments should not be accessible to other apps. In certain third-party document viewers, the documents are automatically synced with different cloud services, which may cause data breach.
MDM secures attachment by using the document viewer, which is a part of the ME MDM app. The document viewer is an optimal way for securing documents. With the document viewer, you can ensure e-mail attachments are
- Viewed only through the document viewer.
- Saved only with the ME MDM app.
- Not copied by the users through clipboard.
- Not accessed by any third party apps.
Thus, MDM app becomes the endpoint for secure document management, ensuring the data is most secure and can be accessed only by the users. Including the above features, it has also the following advantages.
- The document viewer has all the e-mail attachments saved, ensuring easy viewing of all the organizational documents in one place.
- Document Viewer is included as a part of the ME MDM app, ensuring no additional app is to be installed for content management.
- MDM becomes the single point for both device management and content management, ensuring restrictions and profiles can be configured to optimally utilize the document viewer.
- The document viewer doesn't sync with any Cloud service such as iCloud, ensuring there is no copy of the data except in the document viewer.
This is applicable only for iOS devices running iOS 7.0 or later versions.
