Data Sentinel is not designed for this purpose. Data Sentinel was created to detect intrusion rather than to prevent it. It can be used to assess the damage done by hackers and viruses, and to detect unauthorised access to files. In this manner, as well as helping to maintain the integrity of your data and detect intrusion, Data Sentinel can prove to be a highly valuable tool to aid with data recovery in the event of a compromised or damaged system. Because Data Sentinel monitors the actual data stored on a system it is capable of detecting intrusions that different types of Intrusion Detection System cannot.
