Features: Mimecast Advanced Email Security offers robust features such as sandboxing, email archiving, and preventing access to malicious sites, all complemented by efficient filtering.

Room for Improvement: Mimecast could improve its admin console and simplify handling malicious emails, addressing costly data extraction fees and improving its reporting process. Microsoft EOP faces criticism for its high costs and suggests the purchase of additional licenses for advanced features. Users also report configuration challenges and the need for better automated threat detection.
