Salesforce Shield is the strongest match because it is an integrated security, compliance, monitoring, encryption, and auditing suite rather than a single-purpose platform feature. Salesforce identifies Shield capabilities including Event Monitoring, Field Audit Trail, and Shield Platform Encryption , with current Shield offerings also including Data Detect.

Event Monitoring provides granular visibility into user activity and data access, allowing agencies to identify who accessed data and how it was used. Field Audit Trail extends historical field-change retention and supports regulatory, governance, auditing, and forensic requirements. Shield Platform Encryption protects sensitive data at rest while preserving substantial Salesforce application functionality. Salesforce explicitly positions Shield as supporting regulatory compliance and governance requirements.

Setup Audit Trail is useful for tracking administrative configuration changes but does not provide the broader data-access monitoring and encryption capabilities required by the scenario. Classic Encryption is much narrower. Standard Field History Tracking provides basic historical changes but lacks Shield's extended retention and comprehensive auditing functionality.

Salesforce Shield does not itself constitute ISO 27001 certification; rather, it provides technical controls and audit evidence that can support an organization's compliance program.
