Demystifying Field Level Security in Salesforce – Optimizing Data Protection and Access Control


Understanding Field Level Security in Salesforce


Data protection and access control are critical aspects of any Salesforce implementation. Understanding field level security is essential to ensure that sensitive data is properly secured and accessible only to authorized users.

Understanding Field Level Security

Field level security refers to the capability of Salesforce to control access to specific fields within an object. It allows administrators to define who can view, edit, create, or delete specific fields based on user profiles and permission sets.

In Salesforce, field level security works hand in hand with other security measures, such as object-level security, record-level security, and application-level security. While object-level security determines who can access an object, field level security restricts access to specific fields within that object.

Implementing Field Level Security

Accessing field level security settings in Salesforce is a straightforward process. Administrators can navigate to the Setup menu and select the Object Manager, where they can then choose the desired object and modify the field level security settings.

When configuring field level security, administrators can apply different settings to standard objects like Account, Contact, and Opportunity, as well as to custom objects that have been created in Salesforce. For standard objects, field level security can be adjusted directly. For custom objects, administrators have the flexibility to create and manage field level security.

Setting field level security permissions for profiles and permission sets enables administrators to control the visibility and permissions of fields for different user roles. These permission levels include Read, Edit, Create, and Delete, allowing granular control over field access.

Best Practices for Optimizing Field Level Security

When optimizing field level security, it is essential to assess and prioritize data sensitivity. Not all fields require the same level of security, so determining which fields contain sensitive information and applying appropriate security measures is crucial.

Regularly reviewing and updating field level security settings is recommended to ensure that access controls align with changing business needs. Salesforce offers features like field-level security audits and reports, which can be leveraged to assess the effectiveness of the implemented security measures.

Challenges and Limitations of Field Level Security

While field level security is a powerful tool for controlling access to specific fields, it does have certain limitations. For example, field level security applies at the object level, meaning that access cannot be selectively restricted for individual records within an object. Additionally, field level security settings do not apply to data accessed via Salesforce APIs.

To mitigate potential challenges, Salesforce offers alternative security features such as record types, validation rules, and sharing rules. These features can be used in combination with field level security to provide a comprehensive security framework.

Real-World Examples of Field Level Security Implementation

Let’s explore two real-world examples of how field level security can be implemented in different industries:

Use Case 1: Securing Sensitive Customer Data in a Financial Services Company

In a financial services company, it is crucial to ensure that sensitive customer data, such as social security numbers and financial records, is securely protected. Field level security can be used to restrict access to these fields only to authorized employees and managers who require access for their job roles.

Use Case 2: Custom Object Access Control in a Manufacturing Company

In a manufacturing company, custom objects can be used to track and manage various processes and workflows. Field level security can be applied to these custom objects to control access to specific fields, ensuring that only relevant teams or individuals can view or modify the information they need for their tasks.


Field level security plays a significant role in securing sensitive data and controlling access within Salesforce. By understanding and implementing field level security, administrators can ensure that the right users have appropriate access to data while maintaining the confidentiality and integrity of critical information.
