Data Centre Physical security
Zendesk hosts Service Data primarily in AWS data centres that have been certified as ISO 27001, PCI DSS Service Provider Level 1, and/or SOC 2 compliant. Learn more about Compliance at AWS.
AWS infrastructure services include backup power, HVAC systems and fire suppression equipment to help protect servers and your data. Learn more about Data Centre Controls at AWS.
AWS on-site security includes a number of features such as security guards, fencing, security video feeds, intrusion detection technology and other security measures. Learn more about AWS physical security.
Data Hosting Location
Zendesk leverages AWS data centres in the United States, Europe and Asia Pacific. Learn more about Data Hosting Locations for your Zendesk Service Data.
Customers can choose to locate their Service Data in the USA-only or EEA-only.* Learn more about our regional data hosting options and Service Data type restrictions.
*Only available with Data Centre Location Add-on
Dedicated Security Team
Our globally distributed Security Team is on call 24/7 to respond to security alerts and events.
Our network is protected through the use of key AWS security services, integration with our Cloudflare edge protection networks, regular audits, and network intelligence technologies, which monitor and/or block known malicious traffic and network attacks.
Our network security architecture consists of multiple security zones. More sensitive systems, like database servers, are protected in our most trusted zones. Other systems are housed in zones commensurate with their sensitivity, depending on function, information classification and risk. Depending on the zone, additional security monitoring and access controls will apply. DMZs are utilised within the Internet, and internally between the different zones of trust.
Network Vulnerability Scanning
Network security scanning gives us deep insight for quick identification of out-of-compliance or potentially vulnerable systems.
Third-Party Penetration Tests
In addition to our extensive internal scanning and testing programme, each year Zendesk employs third-party security experts to perform a broad penetration test across the Zendesk Production and Corporate Networks.
Security Incident Event Management
Our Security Incident Event Management (SIEM) system gathers extensive logs from important network devices and host systems. The SIEM alerts on triggers that notify the Security team based on correlated events for investigation and response.
Intrusion Detection and Prevention
Service ingress and egress points are instrumented and monitored to detect anomalous behaviour. These systems are configured to generate alerts when incidents and values exceed predetermined thresholds, and use regularly updated signatures based on new threats. This includes 24/7 system monitoring.
Threat Intelligence Program
Zendesk participates in several threat intelligence sharing programmes. We monitor threats posted to these threat intelligence networks and take action based on risk.
Zendesk has designed a multi-layer approach to DDoS mitigation. A core technology partnership with Cloudflare provides network edge defences, while the use of AWS scaling and protection tools provide deeper protection along with our use of AWS DDoS-specific services.
Access to the Zendesk Production Network is restricted by an explicit need-to-know basis, utilises least privilege, is frequently audited and monitored, and is controlled by our Operations Team. Employees accessing the Zendesk Production Network are required to use multiple factors of authentication.
Security Incident Response
In case of a system alert, events are escalated to our 24/7 teams providing Operations, Network Engineering and Security coverage. Employees are trained on security incident response processes, including communication channels and escalation paths.
Encryption in Transit
All communications with Zendesk UI and APIs are encrypted via industry standard HTTPS/TLS (TLS 1.2 or higher) over public networks. This ensures that all traffic between you and Zendesk is secure during transit. For email, our product also leverages opportunistic TLS by default. Transport Layer Security (TLS) encrypts and delivers email securely, mitigating eavesdropping between mail servers where peer services support this protocol. Exceptions for encryption may include any use of in-product SMS functionality. Other third-party app, integration or service subscribers may choose to leverage at their own discretion.
Encryption at Rest
Service Data is encrypted at rest in AWS using AES-256 key encryption.
Availability & Continuity
Zendesk maintains a publicly available system-status webpage, which includes system availability details, scheduled maintenance, service incident history and relevant security events.
Zendesk employs service clustering and network redundancies to eliminate single points of failure. Our strict backup regime and/or our Enhanced Disaster Recovery service offering allow us to deliver a high level of service availability, as Service Data is replicated across availability zones.
Enhanced Disaster Recovery
Our Enhanced Disaster Recovery package adds contractual objectives for Recovery Time Objective (RTO) and Recovery Point Objective (RPO). These are supported through our capability to prioritise operations of Enhanced Disaster Recovery customers during any declared disaster event.
*Only available with the purchase of the Enhanced Disaster Recovery Add-on.
Secure Development (SDLC)
Secure Code Training
At least annually, engineers participate in secure code training covering OWASP Top 10 security risks, common attack vectors and Zendesk security controls.
Framework Security Controls
Zendesk leverages modern and secure open-source frameworks with security controls to limit exposure to OWASP Top 10 security risks. These inherent controls reduce our exposure to SQL Injection (SQLi), Cross Site Scripting (XSS), and Cross Site Request Forgery (CSRF), among others.
Our Quality Assurance (QA) department reviews and tests our code base. Dedicated application security engineers on staff identify, test, and triage security vulnerabilities in code.
Testing and staging environments are logically separated from the Production environment. No Service Data is used in our development or test environments.
Dynamic Vulnerability Scanning
We employ third-party security tooling to continuously and dynamically scan our core applications against the OWASP Top 10 security risks. We maintain a dedicated in-house product security team to test and work with engineering teams to remediate any discovered issues.
Static Code Analysis
The source code repositories for both our platform and mobile applications are scanned for security issues via our integrated static analysis tooling.
Third-party Penetration Testing
In addition to our extensive internal scanning and testing programme, Zendesk employs third-party security experts to perform detailed penetration tests on different applications within our family of products.
Customers can enable native Zendesk authentication, social media Single sign-on (SSO) (Facebook, Twitter, Google) and/or Enterprise SSO (SAML, JWT) for end-user and/or agent authentication. Learn more about user access.
Configurable Password Policy
Zendesk native authentication for products available through the Admin Centre provides the following levels of password security: low, medium and high, as well as set custom password rules for agents and admins. Zendesk also allows for different password security levels to apply to end users vs agents and admins. Only admins can change the password security level. Learn more about configurable password policies.
2-factor authentication (2FA)
Service Credential Storage
Zendesk follows secure credential storage best practices by never storing passwords in human readable format, and only as the result of a secure, salted, one-way hash.
Additional Product Security Features
Role-based Access Controls
Access to data within Zendesk applications is governed by role-based access control (RBAC), and can be configured to define granular access privileges. Zendesk has various permission levels for users (owner, admin, agent, end user etc.).
Learn more about user roles:
- Support Default Roles
- Support Customised Roles *Enterprise only

You can configure your instance so users are required to sign in to view ticket attachments. Learn more about Private Attachments.
Email Signing (DKIM/DMARC)
Zendesk offers DKIM (Domain Keys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting & Conformance) for signing outbound emails from Zendesk when you have to set up an external email domain on your Zendesk. Using an email service that supports these features allows you to stop email spoofing. Learn more about digitally signing your email.
Zendesk tracks the devices used to sign in to each user account. When someone signs in to an account from a new device, it is added to the device list in that user's profile. That user can get an email notification when a new device is added, and should follow up if the activity seems suspicious. Suspicious sessions can be terminated from the agent UI. Learn more about device tracking.
Redacting Sensitive Data
Manual redaction provides the ability to redact, or remove sensitive data in Support ticket comments, and securely delete attachments so that you can protect confidential information. The data is redacted from tickets via the UI or API to prevent sensitive information being stored in Zendesk. Learn more about redaction via the UI or API.
Automatic redaction provides the ability to automatically redact strings of numbers that match a valid credit card primary account number (CC PAN), which match a Luhn check in both Support and Chat. Learn more about automatic redaction in Support and Chat.
Zendesk Support offers a configurable PCI-compliant credit card field which redacts all but the last four digits. Learn more about PCI Compliance at Zendesk.
Spam Filter for Help Centre
Zendesk’s spam filtering service can be used to prevent end-user spam posts from being published in your Help Centre. Learn more about filtering spam in Help Centre.
Human Resources Security
Zendesk has developed a comprehensive set of security policies covering a range of topics. These policies are shared with and made available to all employees and contractors with access to Zendesk information assets.
All employees attend a Security Awareness Training, which is given at hiring and annually thereafter. All engineers receive annual Secure Code Training. The Security team provides additional security awareness updates via email, blog posts, and in presentations during internal events.
Zendesk performs background checks on all new employees in accordance with local laws. These checks are also required to be completed for contractors. The background check includes Criminal, Education and Employment verification. Cleaning crews are included.
All new hires are required to sign Non-Disclosure and Confidentiality agreements.
