I like that proofpoint offers multiple layers of protection, with many different options available. It has been easy to train our employees on how to use it effectively. The price is fair compared to other vendors in this space. Sometimes we get alerts that seem unnecessary, but not enough to make me worry about the system. I would recommend proofpoint for most businesses who want to protect their brand and their data. We have been able to use proofpoint to protect our brand from cyberattacks that could potentially harm or embarrass us.
