Transparent encryption for SQL Server

DbDefence for Microsoft SQL Server provides data-at-rest encryption and additional level of protection for databases.

DbDefence can hide table structure and data from prying eyes, even from DBA!

New: Data Masking with DbDefence

Data masking is a special way of encrypting and displaying sensitive data. Unauthorized users or applications see data in masked form. For example "****-****-****-9363" or "0000 0000 0000 0000" for credit cards. Authorized users or applications see the data transparently in its original form.

DbDefence 7 supports PKCS#11

New release of our DbDefence SQL Server Encryption solution adds support for custom hardware modules in PKCS#11 format. A hardware module can be anything from small USB token to highly effective server PCI board from a well-known vendor.
