Why is NetLib’s Transparent Database Encryption (Whole Database) faster than Column Encryption?

It seems counter-intuitive. Why would performance when working with a wholly encrypted database be better than performance when working with just a few columns? That is because NetLib’s patented Transparent Database Encryption processing actually takes place between the SQL Server and file system layers. Since Transparent Database Encryption works at such a low level, it… Read More

How is Encryptionizer different from other encryption tools?

Our “Split Knowledge Protocol” allows you to split a key among two or more people so that no single person knows the entire key. One optional feature allows you to ask… Read More

Where are the data keys stored?

Data keys are stored with a variety of methods, and we are constantly adding new methods.

The authorized user must… Read More
