End User Privacy

The paragraphs in this section “End User Privacy” provide information on how we use and process information collected about End Users of the Products. It does not cover any other data processing activities.

Zscaler is a “data processor” which processes traffic on behalf of its customer which is the “data controller”. Customers contract with Zscaler to deliver internet security services.

The term “data controller” is defined in European Union (EU) privacy legislation as the natural or legal person, public authority, agency or any other body which alone or jointly with others determines the purposes and means of the processing of personal data. The term “data processor” is defined as a natural or legal person, public authority, agency or any other body which processes personal data on behalf of the data controller.

The “data controller” retains full responsibility for the data with regards to the individual(s) concerned.

EU-U.S. and Swiss-U.S. Privacy Shield Frameworks

Zscaler is a participant in the EU-U.S. and Swiss-U.S. Privacy Shield Frameworks as set forth by the U.S. Department of Commerce regarding the collection, use, and retention of personal information from European Union member countries and Switzerland. Zscaler’s commitment to the Privacy Shield Principles is described in its Privacy Shield Policy. The Federal Trade Commission has investigation and enforcement authority over our compliance with the Privacy Shield.

All legislation referred to herein requires that the relationship between a data controller and a data processor is covered by a contract before outsourcing related to the processing of personal data takes place. The purpose of the contract is to protect the interests of the data controller, who is the entity that determines the purposes and means of processing, and who retains full responsibility for the data with regards to the individuals concerned. The contract thus specifies the processing to be carried out and any measures necessary to ensure that the data is kept secure.

Zscaler Obligations 

Zscaler’s obligations may vary according to the jurisdiction of our customer and their area of business. The typical obligations to ensure compliance with the most common data privacy legislation are as follows: 

  • to comply with current EU/US data transfer principles, EU and Swiss data protection legislation or other similar national legislation as a data processor; 
  • to ensure that the data is only used for the purpose of providing our internet security service and any other purposes that are authorized and/or requested by our customer; and 
  • to keep personal data confidential.

Customer Obligations

To ensure that we process personal data in accordance with relevant privacy regulations, we will only offer our services pursuant to a contract which defines the obligations of Zscaler and our customer according to applicable privacy legislation. Our customer should always comply with relevant privacy legislation as the data controller. Zscaler does not control the sharing of personal information related to our Products; rather, this is governed by our customer (i.e. the data controller), in accordance with the customer’s privacy policy and applicable privacy legislation.

Who Should End Users Contact Regarding Privacy?

If you are an End User of the Products, you should contact our customer (usually your employer) for any information related to information held about you and the privacy policy which governs the relationship between you and our customer.

Privacy Safeguards by Zscaler

Zscaler implements reasonable and appropriate physical, administrative and technical safeguards to help us protect your personal information from loss, misuse, unauthorized access, disclosure, alteration and destruction. For example, we encrypt certain sensitive personal information when we transmit such information over the Internet. We also limit access to personal data and confidential information on our systems to only those employees with a specific need to access this information.

If you are under the age of 13, please do not submit any personal information through our Website or Products.
