Many organizations use an HR integration to pull in accurate employee start/end date data, however if you dont currently have an HRIS in place or use one that's currently supported within Vanta, your Identity Provider will be used as the source of truth for Start and End dates. In some cases, this date may not be accurate.
Adjusting the Start Date:
Due to limitations on how accounts are created in Identity Providers like Google or Okta, the employee's start date in Vanta will align with the date that the account was created in the IDP. So this aligns with what their real life start date is, you have the ability to manually adjust this from the people page in Vanta.
If the date that is reflecting in Vanta is not the accurate start date for this employee, you can navigate to the employee on the people page, click on their name, then select "edit details" on the employee card that appears on the right-hand side of the page:
This change will immediately take effect for that employee. When the time comes for offboarding, Vanta will continue to look to the Identity Provider for the end date.
