What does the term 'threat containment' refer to in Mimecast?

The term 'threat containment' in Mimecast refers to actions taken to isolate and neutralize detected threats in the email environment. This is a critical aspect of email security, as it focuses on preventing identified threats from causing harm to the organization's systems and data. Threat containment involves deploying various strategies to handle malicious emails, such as quarantining potentially harmful messages, blocking phishing attempts, or removing malware before it can affect users. By effectively containing threats, Mimecast helps protect organizations from potential breaches and data loss, ensuring that their email communication remains secure.

The other choices relate to different functionalities and features of email security but do not encompass the concept of threat containment. Enhancing email delivery speeds, types of encryption for securing email, and securely archiving old emails are important components of email management and security strategies but do not specifically address the proactive measures taken to address threats once they have been detected.
