The Challenge

Why the SEG Era Is Ending

MX Rerouting Is a Months-Long Deployment

Standing up a SEG takes weeks of MX changes, policy tuning, and mail-flow testing — every change risks delivery outages.

Signature Engines Can't See Zero-Payload BEC

A SEG's core competency is scanning attachments and URLs — modern BEC ships neither.

Policy Tuning Is a Permanent SOC Cost

Rule maintenance, allow-list management, and false positive triage consume analyst hours every week.

Layered SEG + API Solutions Double the Cost

Running both a SEG and a post-delivery API tool means paying twice for overlapping coverage.

Native Security Alone Leaves Visibility Gaps

M365 and Google Workspace alone don't cover BEC, vendor compromise, or cross-account behavioral correlation.

The Solution

How Abnormal Replaces Your SEG

  1. Replaces the entire SEG with one behavioral engine — spam, malware, phishing, BEC, vendor fraud, and account takeover handled without signature lists to maintain.
  2. Layers on top of native Microsoft or Google security via API in minutes — no MX changes, no mail rerouting, no maintenance windows.
  3. Runs alongside your existing SEG so you can compare real detection data before decommissioning with confidence.

Core Capabilities

Built for Modern Email Attacks

Full Threat Coverage in One Platform
