Shield Platform Encryption is an add-on feature for Salesforce that allows you to encrypt your data at rest, rather than just during transmission over a network. [Shield Platform Encryption](https://help.salesforce.com/s/articleView?id=xcloud.security_pe_overview.htm&type=5&language=en_US) allows you to protect data in some standard fields, certain types of custom fields, files and attachments that are stored on the platform, and search indexes. [Standard encryption](https://help.salesforce.com/s/articleView?id=platform.fields_about_encrypted_fields.htm&type=5&language=en_US) is included with your Salesforce licenses. Shield Platform Encryption requires an additional fee. The encryption type for standard encryption is 128-bit Advanced Encryption Standard, while Shield is 256-bit. Standard encryption provides an encrypted text field type, while Shield Platform Encryption can be applied to many different types of fields, files, attachments, and search indexes. ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-sfdo-program_management_module-264-0-0-production-enus/443b48d5-82c1-45d8-a7f7-2c07521b8b28/images/icon_note.png) Note Shield Platform Encryption isn't for everyone.
