Data Residency and Sovereignty Compliance

Thales e-Security helps enterprises and cloud providers meet data residency and data sovereignty regulations

Data Residency

With more than 100 national data privacy laws on the books as of the end of 2016 (including the landmark GDPR in Europe), any global enterprise, SaaS vendor or cloud solution provider needs to pay attention to how data residency requirements for data-at-rest can be met within their environment.

Data Residency
One General Rule

Though there is a wide variation between requirements, meeting this single rule ensures that your organization remains in compliance:

  • All customer and employee data must not be accessible to those outside of their home legal jurisdiction
  • Exception: When explicit consent is given on a per usage basis
  • Encrypt Data at Rest and Restrict Data Access

    The solution to the problem is to encrypt all data-at-rest and only allow access to data-at-rest from the jurisdiction where it originates.

    With Thales e-Security, solving the problem is simple. Using Thales e-Security data-at-rest encryption with access control to limit data access to only those within a specific jurisdiction will satisfy all but a few national requirements (Germany and Spain are specific exceptions).

    For Enterprises

    At the file system and volume level, encrypt data sets from each jurisdiction with Vormetric Transparent Encryption. Set access controls (linked to your directory services infrastructure) so that the data-at-rest can only be decrypted by those within each country. Others will have no access to information, seeing only encrypted data blocks. For best practice, have each country keep their own encryption keys locally, so that even security management personnel from outside their jurisdiction cannot change encryption keys or access policies.

    For access to information stored within databases and applications – link access to directory services infrastructure or other access management tools. You can also encrypt data on a column, field or database file level with Vormetric Application Encryption, and manage encryption keys using the Vormetric Data Security Management appliance interfaces to match jurisdictions. Enterprises can use Vormetric’s centralized, uniformly managed Data Security Manager to coordinate these operations.

    Vormetric’s Data Security Platform from Thales e-Security also features the Vormetric Cloud Encryption Gateway, which extends the Platform to safeguard sensitive data in cloud storage environments, including Amazon S3, Box and Caringo. The cloud security gateway encrypts sensitive data before it is saved to the cloud. This enables security teams to establish the visibility and control they need around sensitive assets without having to add another point tool that increases system complexity.

    For Cloud Providers

    Offer customers the option to encrypt data-at-rest, managing their own encryption keys from within their local jurisdiction, and locking out access by others. With Vormetric Transparent Encryption from Thales e-Security, data-at-rest encryption is done by giving each customer its own local, physical or virtual Vormetric Data Security Manager, combined with agents on each customer system linked to that management instance.
