E-mail is the primary conduit of information for many organizations, both internally and with the outside world. Unfortunately, e-mail is also a prime channel for annoyances such as spam, as well as security threats in the form of viruses, spyware, phishing attacks, and more. Some companies choose to defend their e-mail systems in-house by deploying e-mail security products. Others, however, look to outside assistance in the form of hosted e-mail security services.
