How can I be sure that my redactions are truly permanent in Acrobat?

After you apply redactions, save the document. Close the document and reopen it. Try to select the redacted area or search for the hidden words. If you cannot select or find the words, the redaction worked. Also, run the 'Sanitize' tool to remove any hidden data.

What kind of 'hidden data' does Acrobat's Sanitize tool remove, and why is it important after redacting?

The Sanitize tool removes metadata (like author, creation date), hidden layers, comments, attachments, and old versions of the document. It's important because even after redacting visible content, this hidden data might still contain sensitive information. Sanitizing ensures that no sensitive details are left in the file, making the document truly secure before sharing.

Always use the specific redaction tool for security.

For many items like Social Security Numbers (SSNs) or account numbers, use the pattern-based auto-redaction feature. This tool can find and redact all matching patterns automatically. After it runs, have another person check a few random pages to make sure it worked correctly.
