Definition
Custom Permissions is a Setup page where administrators create named permissions that can be assigned to users via Permission Sets or Profiles. Custom Permissions act as feature flags that developers and administrators can check in Apex code, validation rules, and Flows to control access to custom functionality without modifying profiles.
Real-World Example
The developer at CloudBridge Solutions creates a Custom Permission called "Can_Override_Discount." She adds a check in the Apex trigger: if the current user has this permission, they can apply discounts above 30%. The admin then assigns this permission to a "Sales Directors" Permission Set, giving only directors the ability to override the discount limit.
Why Custom Permissions Matters
Custom Permissions is a foundational element of Salesforce administration. Admins rely on it to control how users interact with the platform, ensuring that the right people have the right access while maintaining data integrity across the organization. Misconfiguring this area can lead to security gaps, data leakage, or frustrated users who cannot do their jobs.
As your Salesforce org grows and evolves, Custom Permissions becomes increasingly important for governance. It helps administrators enforce business policies without writing code, making it an essential tool for the 80% of Salesforce customization that happens declaratively through clicks, not code.
How Organizations Use Custom Permissions
- •Cyberdyne Co — Configured Custom Permissions to enforce their data governance policies across 500+ users. By setting up proper controls, they reduced unauthorized data exports by over 90% and passed their annual security audit without any findings for the first time.
- •Soylent Group — Used Custom Permissions to streamline their onboarding process for new hires. Instead of manually configuring access for each person, they built standardized configurations that could be assigned in minutes, reducing IT onboarding time from two days to under an hour.
- •Acme Corporation — Applied Custom Permissions as part of a broader org cleanup initiative. By auditing and optimizing their setup, they improved page load times, reduced user confusion caused by unnecessary fields, and made their Salesforce instance more maintainable for the admin team.
