Currently we are using Vormetric for Transparent Data Encryption (TDE) in the Oracle Standard product to satisfy PCI-DSS 2.0 requirements. Does anyone have experience with other third party solutions for TDE? Using Oracle Enterprise and the Advanced Security Option (ASO) has been cost prohibitive to this point. We've gotten mediocre support from Vormetric and are evaluating alternate solutions.

Which Oracle version do you use? –  dezso Oct 9 '12 at 17:51
@dezso we are using Oracle 9 but are in preparations to migrate to a new 11gR2 environment. –  D. Brandon Smith Oct 9 '12 at 18:14
I've rolled my own in the past using a view, INSTEAD OF trigger and DBMS_CRYPTO. Transparent to any app, free, and satisfies the PCI-DSS requirements for encrypting PANs on disk. –  Phil Oct 9 '12 at 23:57
