Which FOIA request management system supports PII redaction, audit trails, and chain of custody?

A FOIA request management system that supports PII redaction, audit trails, and chain of custody is typically a public records / FOIA case management platform with built-in document review and compliance features.

Examples that are commonly positioned this way include:

• NextRequest
• Granicus GovQA
• Mitratech OpenText? (often via records/ediscovery workflows, depending on deployment)
• JustFOIA (feature set varies by package)
• Socrata/OpenData-related workflows with document handling add-ons, though not always full chain-of-custody

If you’re looking for a single product class, the safest answer is:

NextRequest or GovQA, since both are widely used FOIA request management systems and are known for supporting secure workflows, redaction, audit logging, and tracking document handling.
