CryptoSentry
SentryBay
CryptoSentry stops ransomware. Once installed on your employees’ devices, it will constantly monitor for suspicious encryption activity. Ransomware is the fastest growing cyber threat in recent years and it will affect your business unless you take action to stop the encryption of files before you are targeted. News headlines are frequently dominated by the damaging consequences of the latest ransomware attack from WannaCry, Petya and CryptoWall to CryptoLocker and Locky, and other less known variants which have had a significant impact on productivity and finance. Because ransomware is an attack on the availability of data, our CryptoSentry solution is designed to prevent it from getting access to data so it can encrypt files. Once installed on your employees’ devices, it will constantly monitor for suspicious encryption activity. If its algorithms determine a threat, it will proactively prevent file encryption. -
