Built on a foundation of trust.

At Workday, trust is woven into the fabric of everything we do. To keep your data safe and private, we deploy industry-leading safeguards and continuously monitor our system so you can rest easy knowing your most sensitive data is protected 24/7 in the cloud.


We employ rigorous security measures at the organizational, architectural, and operational level to ensure that your data, applications, and infrastructure remain safe.

And because security is a collective effort, we also provide you with tools to configure data access within our applications.


At Workday, security begins on day one. All employees receive security, privacy, and compliance training the moment they start. Though the extent of involvement may vary by role, security is everybody’s responsibility at Workday.

This commitment to security extends to our executives. The Workday Security Council, a cross-functional group of executives spanning the enterprise, shapes our security programs, drives executive alignment across our organization, and ensures that security awareness and initiatives permeate throughout our organization.


Processing Relationship

At Workday, our customers serve as the data controller while Workday is the data processor. This means that you have full control of the data entered into services, as well as all setup and configurations. Because you control your data—and we only process it— you won’t have to rely on us to perform day-to-day tasks such as:

  • Assigning security authorization and manipulating roles.
  • Creating new reports and worklets.
  • Configuring business process flows, alerts, rules, and more.
  • Creating new integrations with Workday utilities or incumbent tooling.
  • Changing or creating new organizational structures.
  • Monitoring all business transactions.
  • Looking at all historical data and configuration changes.
Data Encryption

Workday encrypts every attribute of customer data before it’s persisted in a database. This is a fundamental design characteristic of the Workday technology. Because Workday is an in-memory, object-oriented application instead of a disk-based RDBMS, we can achieve the highest level of encryption. We use the Advanced Encryption Standard (AES) algorithm with a key size of 256 bits and a unique encryption key for each customer.

Transport Layer Security (TLS) protects user access via the internet, helping to secure network traffic from passive eavesdropping, active tampering, or message forgery. File-based integrations can be encrypted via PGP or a public/private key pair generated by Workday, using a customer-generated certificate. WS-Security is also supported for web services integrations to the Workday API.

Logical Security

Workday security access is role-based, supporting LDAP Delegated Authentication, SAML for single sign-on, and x509 certificate authentication for both user and web services integrations.

Delegated Authentication: Workday supports delegated authentication via your on-premise LDAP server, such as Microsoft Active Directory. This allows your security team to disable a user account centrally from the LDAP server without logging in to Workday. Workday can also automatically update the LDAP server with new active user accounts for new hires, or deactivate accounts for employee separations and employees on leave of absence.

Single Sign-On Support: SAML allows for a seamless, single-sign-on experience between the customer’s internal web portal and Workday. Customers log in to their company’s internal web portal using their enterprise user name and password and are then presented with a link to Workday, which automatically gives customers access without having to log in again. Workday also supports OpenID Connect.


Physical Security

Workday applications are hosted in state-of-the-art data centers designed to protect mission-critical computer systems with fully redundant subsystems and compartmentalized security zones. Our data centers adhere to the strictest physical security measures including, but not limited to, the following:

  • Multiple layers of authentication for server area access.
  • Two-factor biometric authentication for critical areas.
  • Camera surveillance systems at key internal and external entry points.
  • 24/7 monitoring by security personnel.

All physical access to the data centers is highly restricted and stringently regulated.

Network Security

Workday has established detailed operating policies, procedures, and processes designed to help manage the overall quality and integrity of the Workday environment. We’ve also implemented proactive security procedures, such as perimeter defense and network intrusion prevention systems (IPSs).

Network IPSs monitor critical network segments for atypical network patterns in the customer environment as well as traffic between tiers and service. We also maintain a global Security Operations Center 24/7/365.

Application Security

Workday has implemented an enterprise Secure Software Development Life Cycle (SDLC) to help ensure the continued security of Workday applications.

This program includes an in-depth security risk assessment and review of Workday features. In addition, both static and dynamic source code analyses are performed to help integrate enterprise security into the development lifecycle. The development process is further enhanced by application security training for developers and penetration testing of the application.

Vulnerability Assessments

Workday contracts with third-party expert firms to conduct independent internal and external network, system, and application vulnerability assessments.

Network: External vulnerability assessments scan all internet-facing assets, including firewalls, routers, and web servers for potential weaknesses that could allow unauthorized access to the network. In addition, an authenticated internal vulnerability network and system assessment is performed to identify potential weaknesses and inconsistencies with general system security policies.

Application: We contract with a leading third-party security firm to perform an application-level security vulnerability assessment of our web and mobile application prior to each major release. The firm performs testing procedures to identify standard and advanced web application security vulnerabilities, including, but not limited to, the following:

  • Security weaknesses associated with Flash, Flex, AJAX, and ActionScript.
  • Cross-site request forgery (CSRF).
  • Improper input handling (such as cross-site scripting, SQL injection, XML injection, and cross-site flashing).
  • XML and SOAP attacks.
  • Weak-session management.
  • Data validation flaws and data model constraint inconsistencies.
  • Insufficient authentication or authorization.
  • HTTP response splitting.
  • Misuse of SSL/TLS.
  • Use of unsafe HTTP methods.
  • Misuse of cryptography.
