SQL professionals agree that the default trigger, view and procedure encryption that comes with MSSQL 2012, 2008, 2005, 2000 and 7.0 is ineffective and easily broken. In fact, Google generates over 3700 links for a search phrase "SQL decryptor", offering dozens of software solutions that can bypass MSSQL "native" encryption. Yet, for many companies that use MSSQL for processing sensitive and confidential data, compromising the integrity of encrypted procedures or triggers is not an option.
