Cloud - based whitelisting is very popular among antivirus software and many companies are using it to speed up the scans and the overall performance. Such feature in Bitdefender will ensure it keeps the highest detection rate and improve it's speed. You already have cloud antivirus available in romanian language and you have many users, so I bet it won't be that hard to implement. Cloud - based whitelisting can also lower the number of false positives and you will be able to set higher levels of Active Virus Control and Intrusion Detection System by default. This will greatly increase the security.
