Some data may need to be protected from unauthorized access (e.g., theft, modification). Neo4j does not deal with data encryption explicitly, but supports all means built into the Java programming language and the JVM to protect data by encrypting it before storing.

Furthermore, data can be easily secured by running on an encrypted datastore at the file system level. Finally, data protection should be considered in the upper layers of the surrounding system in order to prevent problems with scraping, malicious data insertion, and other threats.
