As reported on Security Pipeline, a study from security software provider Proofpointfirms found that 43% of companies are reading more outbound email than ever. The study also found that firms have employees that monitor these emails and over 20% of firms also monitor outgoing instant messages. While some of this activity is dedicated to scanning outgoing email for viruses, it does raise privacy concern for employees. However, many companies have been monitoring employee phone calls for some time now.
