I came across an interesting encryption solution today that can work with an Oracle database amongst others. The product is https://www.ingrian.com/products/ - (broken link) Ingrian network Inc'c DataSecure. It is a network appliance that employs redundancy in its components and provides fast hardware based cryptography. The product has three components, one of which is a software adaptor that allows seamless use with database applications. Oracle is supported. I do not know about costs and I have not seen the product in real life but it sounds like quite an interesting solution to the legislation issues currently amongst us. I have added the product to my
Oracle Security Tools page in the commercial section and I have added some description of it there. If you are looking for encryption solutions that provide hardware encryption, component redundancy and also FIPS 140-2 level 3 compliancy to provide tamper proof protection of the keys then this product sounds like it’s worth a look.
