Abnormal Security vs Proofpoint

Abnormal Security represents a fundamentally different approach to email security compared to Proofpoint. While Proofpoint operates as a full secure email gateway that inspects content, URLs, and attachments, Abnormal uses behavioral AI to detect anomalies in communication patterns. Abnormal excels at catching socially-engineered attacks that contain no malicious payloads, while Proofpoint provides broader protection across the full spectrum of email threats. Many organizations deploy Abnormal as a supplementary layer behind Proofpoint to catch what the gateway misses.

The Bottom Line

Choose Abnormal Security if BEC and social engineering are your top concerns and you want the best AI-powered behavioral detection, especially as a layer on top of an existing gateway. Choose Proofpoint if you need a comprehensive email security platform that covers the full threat spectrum plus DLP, archiving, and compliance in a single solution.

Choose Abnormal Security if:

  • You need a comprehensive email security platform covering threats, DLP, and compliance
  • You require email archiving and regulatory compliance capabilities
  • You face a broad range of email threats including malware and ransomware
  • You want a single platform rather than layering multiple email security tools
  • You need security awareness training integrated with your email protection

Choose Proofpoint if:

  • Business email compromise and social engineering are your primary email threat concerns
  • You want to supplement your existing email gateway with AI-based behavioral detection
  • You need vendor and supply chain fraud detection capabilities
  • You prefer API-based deployment without MX record changes
  • Your current gateway misses socially-engineered attacks with no malicious payload
