Mimecast

Mimecast Email Security is a cloud-based email security platform that protects organizations against advanced email threats including phishing, business email compromise, malware, and spam. It provides multiple layers of detection including URL protection, attachment sandboxing, impersonation protection, and internal email monitoring. 

For security response actions, Mimecast enables blocking and unblocking of email addresses and domains at the email gateway, preventing malicious senders from reaching user inboxes. These capabilities are essential for containing email-borne threats, stopping active phishing campaigns, and blocking communication with compromised or malicious email addresses during security incidents.
