The Zendesk Shared Responsibility Model
Zendesk provides a highly configurable, rapidly scalable customer service platform to many of the world’s leading companies across a wide swath of industry sectors. By helping our subscribers leverage our Cloud platform for their customer service needs, we allow them to reduce overhead, scale to meet demand, and provide beautifully simple interactions with their customers.
Moving business into the Cloud brings not only the benefits described above, but can include ambiguity regarding which party is in charge of which control. Not to worry, in order to keep this simple, below you’ll find our Shared Responsibility Model. This framework clarifies which party is responsible for which controls related to the security and privacy of your data. Whether you’re a conscientious admin, corporate security, compliance, or privacy official, or anyone else tasked with setting up appropriate controls for the use of Zendesk Services in your environment, this standard should clearly draw the lines you need to be aware of.
To encapsulate it in one sentence, “Zendesk is tasked with the security of the Service itself, while you are tasked with the security within your particular instances of the Service”.

I. Access Controls and Hygiene
Controlling access to sensitive systems and the data within them is core to security principles.
- The Subscriber is responsible for all access controls to their instances of the service including:
- Provisioning, modification, ongoing hygiene, maintaining privilege accuracy, and de-provisioning of all users including end users and agents (be they on-premise, remote, or third party workforce)
- Choosing and configuring the method of authentication into the service from supported offerings (may include passwords, MFA, SSO, etc)
- Configuring and monitoring aspects of session handling such as logouts, logged in devices, etc.

- Considering other non-product related access controls such as which device types you permit agents to use when accessing your instances, as well as any applicable physical, logical, or policy controls for your users or permitted devices
- Zendesk is responsible for all access controls to the systems underpinning the service including:
- Maintaining policies and procedures for safely provisioning, modification, ongoing hygiene, maintaining privilege accuracy, and de-provisioning of all users (including on-premise, remote, and third party workforce)

- Performing periodic checks on the above
Leveraging third parties can greatly improve efficiency, but also introduces security considerations.

III. Data, Privacy, Compliance, and Regulatory Considerations
Accounting for the data in use, its proper treatment, any relevant regulatory frameworks, and the importance of third party assurances is a must.
- The Subscriber is responsible for proper treatment of the data they take in and use, including:

- Providing Zendesk with alternate TLS certificates where host mapping to a non-Zendesk parent domain is desired for the encryption of traffic to and from Zendesk UI’s or API’s
- Understanding where data may not be encrypted in transit and treating such channels or protocols accordingly (primarily email, SMS, or third party integrations made at subscriber’s sole discretion which do not support encryption)
- Ensuring the data types involved in subscriber’s instance do not violate the terms and conditions of Zendesk’s Master Subscription Agreement (please refer to Zendesk MSA)
- Ensuring the level of uptime and disaster recovery subscriber chooses is in accordance with any policies or regulations subscribers are beholden to

- Encrypting data in transit to or from our UI’s or API’s over public networks
- Encrypting all Service Data at rest
- Providing subscribers with information on data collected by in-product cookies as well as default use of the services
- Accurately describing how we use Service Data, including Personal Data, in anonymized and non-anonymized manners to provide our Services or otherwise.

V. Security Incidents
Despite best efforts, things can sometimes go wrong. How you recognise, respond, and recover from a security incident is key to successful mitigation and keeping customer trust. This section lays out the roles and responsibilities of each party during security incidents.
- The Subscriber is responsible for any security incident or breach within their particular instances, which was not caused by, or made via vulnerabilities or incidents within the service itself, including
- Investigating and remediating any any suspected or actual breach within their particular instance caused by (i) insufficient access control or hygiene, (ii) insufficient monitoring of user activities, (iii) failure to perform due diligence on communications or untrusted content derived via interactions with users, or (iv) any incident or breach brought on via integration with any third party, where such integration was made at the subscriber’s sole discretion.
- Making any required notifications to government or law enforcement agencies, or end users related to breaches caused by Subscriber actions, integrated third parties, or related to Service Data Breach notifications received from Zendesk regarding Subscriber’s instance
