What is Email Security?

Email security refers to the collective measures used to protect email accounts and communication from unauthorized access, loss, compromise, and various threats. These threats include spam, phishing, malware, business email compromise (BEC), and data breaches. Common security measures include spam filtering, anti-malware scanning, encryption, authentication protocols (like SPF, DKIM, and DMARC), and employee training on recognizing and avoiding phishing attempts. Email security solutions can be deployed as software, hardware appliances, cloud services, or a combination thereof, and are critical for protecting sensitive information, maintaining regulatory compliance, and preserving an organization's reputation.
