Measures protecting email systems and users from threats like phishing, malware, and data loss.
Email security encompasses technologies and practices protecting email systems from threats and preventing email-based attacks. This includes spam filtering, malware detection, phishing protection, encryption, data loss prevention, and authentication protocols (SPF, DKIM, DMARC). Email remains the primary attack vector—most breaches begin with malicious emails. Layered email security combining multiple technologies provides the best protection.
Why It Matters
The DSC Perspective:
Email is how most attacks arrive. Effective email security is essential for any organisation. Layer multiple protections—gateway filtering, authentication, user awareness—for comprehensive protection.
