Email Security Services FAQs

Email Security is the practice of protecting email, associated systems, and data from unauthorized use or cyberattack.
Email security threats come in many forms, including malware delivery, ransomware and phishing attempts. The biggest email security threat, however, is the one that actually makes it to your inbox, hence the need for inline protection.
An SEG is a product or solution that detects malicious emails or content and rejects or quarantines them.
API-based email security is superior to an SEG for several reasons, including:
  • Internal awareness: An API-based solution like Avanan scans internal traffic and learns from internal data; an SEG only gatekeeps incoming emails.
  • Multilayer protection: An API-based solution provides additional layers of security, working alongside default security. The same default security functions (of Microsoft and Google, for example) must be disabled to use an SEG.
  • Full-suite security: An API-based solution secures the full communications suite, including connected applications, into which an SEG has no visibility.
