NeuShield Data Sentinel takes a completely different approach by creating a protective shield between your files and applications. When ransomware or other applications make changes, the original files stay intact allowing users to revert any unwanted change that has been made. While other products create backup copies of your files which, can dramatically increase disk usage and cause a significant performance overhead, NeuShield’s revolutionary Mirror Shielding™ technology can preserve the original file without requiring a backup, which allows Data Sentinel to protect files with virtually no additional disk activity (I/O).
