Email Security Services FAQs
Email security services protect organisations from email-based cyber threats such as phishing, malware, ransomware, and business email compromise. They also support email continuity, data protection, and regulatory compliance.
Native email security tools provide baseline protection but often lack advanced threat detection, continuity, and data loss prevention. Many organisations use additional email security services to close these gaps and reduce risk.
Email security protects against:
- Phishing and spear phishing
- Malware and ransomware
- Business Email Compromise (BEC)
- Domain and sender impersonation
- Malicious links and attachments
- Accidental or intentional data leakage
Business Email Compromise is a targeted attack where criminals impersonate trusted individuals or domains to trick users into transferring money or sensitive information. Advanced email security uses behavioural analysis and impersonation detection to prevent BEC attacks.
