Mimecast Cloud Archiving, Search & Discover |
| Who's affected | Administrators and all Mimecast Archiving customers with access to Search & Discover |
Overview
Mimecast is pleased to announce Redaction for Search & Discover. This is a new capability within Search & Discover that lets reviewers permanently obscure sensitive or non-relevant information from search results before that data is exported and shared outside the organization. Users with the appropriate permission can define a list of keywords and phrases (Find & Redact), or highlight the content in the message body they want redacted, and have every exact match across their search redacted at the point of export.
What's changing
With this new feature, customers can do the following:
Define: Within a Search & Discover search, a user with the Redact permission opens the Find & Redact modal and provides a list of keywords and phrases, or highlights terms directly in the content view using Redaction mode.
Match: Terms are matched using exact match, case-insensitive, no stemming — "car" matches "car" but not "cars". Matching applies to the message body.
Export: Redactions are applied at the point of export. Every redacted occurrence is removed from the data.
Redaction is non-destructive: redactions are applied only at the time of export. The underlying archived content is never modified, preserving the integrity and evidential value of the archive while producing a safe-to-share output. Every redaction action is captured in the audit log.
Recommended actions
If this is a feature of interest, please add the redaction permission to the relevant user's role in Aware to grant the capability.
