Companies are not embracing encryption as a way to protect sensitive data. According to Ponemon Institute’s 2005 National Encryption Survey, only 4.2% of companies responding to our survey say their organizations have an enterprisewide encryption plan.
However, the study also reveals that encryption is viewed by many as an important security tool that enhances the IT professionals’ overall sense of trust or comfort in data-protection efforts. The primary reasons cited for not encrypting sensitive or confidential information were concern about system performance (69%), complexity (44%) and cost (25%).
