What does the term 'quarantine' refer to in Mimecast?

The term 'quarantine' in Mimecast refers to a storage area for potentially dangerous emails that are held for review before they are delivered to the user's inbox or deleted. This feature serves as a protective measure, allowing administrators and users to analyze suspicious emails, which could contain malware, phishing attempts, or other security threats. By reviewing these emails, users can make informed decisions about the safety of their communications and protect their systems from potential harm.

This process is critical in email security management, as it helps to prevent harmful content from reaching users directly while still preserving the messages for further examination. Users can typically access their quarantine through the Mimecast web interface, where they can view, release, or delete emails as needed. The other options do not accurately describe the function of quarantine in Mimecast, as none encompass the essence of holding potentially harmful emails for further assessment.
