Email is an essential communications and collaboration tool for all organisations as it contain a great deal of sensitive and often confidential information that is among the most important business records produced by an organisation. It is therefore vital that high levels of security be used for email, both at rest and in transit. This is important not just for protecting the organisation from the harm caused by email-borne threats, but also to ensure that it is safe when stored so that the information cannot be accidentally leaked out of the organisation.
This document discusses the business case for implementing strong email security controls and outlines what organisations should look for when selecting a product or service. It is intended to be read by organisations of all sizes across all vertical industries and describes the capabilities of some of the major vendors in the market.
