Why Businesses Switch to OpenEFA

AI That Catches What Others Miss

Our proprietary machine learning engine uses NLP, intent classification, behavioral analysis, and sender reputation scoring to detect sophisticated threats that rule-based filters can't see.

  • Business Email Compromise (BEC) detection
  • NLP-powered phishing and spoofing analysis
  • First-contact and new sender alerts
  • URL and attachment risk scoring

Privacy-First Architecture

Most email security vendors send your messages to third-party cloud AI platforms for analysis. OpenEFA is different.

  • AI runs entirely within our controlled infrastructure
  • Your email data never leaves to train external models
  • No data shared with big tech AI projects
  • Enterprise-grade protection, zero data exposure

Works With Any Email System

Cloud or on-premise, OpenEFA integrates with your existing mail infrastructure in minutes.

  • Microsoft 365 / Exchange Online
  • Google Workspace
  • Zoho Mail, Rackspace, FastMail
  • Exchange, Zimbra, Postfix, and more

Full Transparency, No Black Box

Every filtered email includes a detailed explanation of why it was blocked or delivered.

  • AI score and rule breakdown for every message
  • Intent analysis and risk details
  • Web-based quarantine management portal
  • Per-domain scoring and custom rules
