Data Privacy Information Sheet:
Proofpoint Discover

The purpose of this document is to provide customers of Proofpoint Discover (formerly, E-Discovery Analytics) with the information necessary to assess how the product can support and enhance their data privacy strategy.

Proofpoint Discover – Product Statement

Legal, compliance, and security pressures are evolving in the face of today’s data growth. That’s why customers need a new secure approach to enterprise archiving challenges. Proofpoint Enterprise Archive (“Archive”) is a cloud-based archiving solution that simplifies legal discovery and end-user data access. It provides customers with a secure and searchable central repository of a wide range of content types without the challenges of managing in-house. With Proofpoint Discover (and add-on to Archive), customers can process, analyze, and cull archived information in-house. This helps customers streamline processes and dramatically reduce the scope e-discovery costs.

Information Processed by Proofpoint Discover

Proofpoint Discover processes and stores communications (both internal and external) of various types. The complete composition of the original content and its metadata are preserved for the period defined by the customer in the customer’s retention configuration. To facilitate attribution of items to users, the system stores and maintains a historical record of employees and their key attributes, including their name, business phone number, email addresses, job function, and department.

As the full content of all messages is preserved, all types of potentially sensitive data may exist within Archive, including:

  • Personal financial information (sometimes known as PCI data), including, but not limited to, credit card numbers and bank account numbers
  • Personal healthcare information, including, but not limited to, national identifiers adn insurance numbers
  • Personal identifiable information (PII), including, but not limited to, names and email addresses


Customer Access to Archived Data and Privacy Options

Access to Archive data, including those assigned to cases within Proofpoint Discover, may be controlled by policies set by customer security administrators. Access can be assigned to specific users and groups. Data is made available to authorized users and groups through the solution’s user interface.

How Proofpoint Retains Records

Proofpoint customers can select a retention period (in months) for which the data is retained. Once items have achieved this policy-based retention period, the customer can authorize disposition of the data (or the system can do so automatically if so configured).

Proofpoint’s Use of Subprocessors

Proofpoint utilizes subprocessors to provide its services. A comprehensive list of the subprocessors may be found on the Trust site at
