As email is now fully embedded as a business tool and is being used to transfer critical, sensitive data, it is becoming increasingly important to provide a secure, robust and manageable encryption service for email users.
Email encryption cannot be addressed as a standalone proposition. It must be considered as part of an organisation-wide encryption service, providing security for other applications and line of business solutions.
Some email traffic is now far too important to encrypt solely at an organisation’s gateway to the outside world. The rise of the inside threat means that all organisations need to consider who can access internal messages and ensure that this risk is mitigated, if appropriate, from sender through to recipient.
A mature, blended approach to email encryption that encompasses an intelligent analysis of the risks to data and the associated data value will enable organisations to implement a cost effective, robust and reliable solution.
- Email encryption should be of strategic concern to businesses given the possible value of data contained in many messages.
- Appropriate levels of encryption should be applied intelligently.
