Barracuda Essentials for email is a cloud-based spam & email threat filter that prevents web-borne email threats. Barracuda Essentials is presented as an ‘all-in-one’ solution, including email threat prevention, data leakage protection (DLP), and email archiving. Barracuda Essentials and Mimecast are similar, but Barracuda Essentials stands out in several areas, including lower performance in URL and spear phishing & Business Email Compromise (BEC). Mimecast has no account takeover protection.
