It is important to sanitize contract copies to ensure privacy and compliance. Documents can contain hidden data like author names, creation dates, or even deleted text in the background. Sanitizing removes this invisible layer, preventing accidental disclosure of sensitive information and maintaining confidentiality.

No, if you only redact visible text, your contract is not fully secure. Redaction handles what you can see, but documents often have an invisible layer of data. This hidden data, like comments or document properties, can still be accessed. For full security, you must also use 'Sanitize Hidden Data' to remove this invisible information after redacting.
