SharePoint sharing link security

Hi @Titus Tolbert (Sr. Dev Operation, Hoka corp)

Thank you for posting your question in the Microsoft Q&A forum. 

From your description, my suggestion is creating separated links for internal and external users.

For external, you can use this method Web.CreateAnonymousLinkWithExpiration method 

For internal, you can use either

Web.ShareObject Method (Microsoft.SharePoint.Client) | Microsoft Learn or

Web.CreateOrganizationSharingLink Method (Microsoft.SharePoint.Client) | Microsoft Learn

You can read at CSOM SPT for more details how to use it:

[MS-CSOMSPT]: CreateOrganizationSharingLink | Microsoft Learn

[MS-CSOMSPT]: ShareObject | Microsoft Learn

[MS-CSOMSPT]: CreateAnonymousLinkWithExpiration | Microsoft Learn

I hope this information helps.
