Field-level security (FLS)
Dataverse's mechanism for restricting access to specific columns within a row — through field security profiles assigned to users and teams.
Field-level security (FLS) in Dataverse restricts access to specific columns within a row, beyond row-level security from security roles. A column is marked Secured; users see it only if they belong to a field security profile that grants Read / Update / Create access. Common uses: HR data (Salary, Performance Rating), sensitive financial data (Credit Score, Internal Risk Assessment), PII (SSN, Date of Birth), internal-only notes. The platform enforces FLS at form rendering, API responses, reports, and views — secured fields are stripped from responses to unauthorised users. Mobile offline caches also respect FLS — sensitive data isn't cached on devices users without access. Use FLS selectively for genuinely sensitive columns; don't apply universally.
