Email Security

Email security vendors are rapidly bolstering social engineering detection capabilities in response to the escalating pace of phishing and business email compromise (BEC) attacks. Buyers must consider complementary or supplemental email security solutions to align with best practices for combating modern email threats.

Market Definition

Gartner defines an email security solution as a product that secures email infrastructure. Its primary purpose is to protect against malicious messages (phishing, social engineering, malware) or unsolicited messages (spam, marketing). Other functions include email data protection; domain-based message authentication, reporting and conformance (DMARC); investigation; and remediation through a dedicated console. Email security solutions may also support nonemail collaboration tools, such as those for document management and instant messaging.

Email security tools protect an organization’s email from spam, phishing, malware attacks, account takeover and data loss. They may provide capabilities for data loss prevention, encryption, domain authentication and security education, as well as advanced protections against business email compromise. Email security platforms give cybersecurity teams visibility into email-related security incidents, support investigation and automated remediation, and enable management of both inbound and outbound email delivery. Email security solutions often integrate with other network, identity and endpoint security controls, and may also support collaboration tools and email relay capabilities.
