Obsidian Security vs Abnormal Security Comparison

This document is a technical report comparing the identity threat prevention capabilities of Obsidian Security and Abnormal Security. It outlines the challenges posed by identity-based attacks, particularly spear phishing, and discusses how Abnormal Security employs behavioral AI technology to detect anomalies in email communications. However, it notes that Abnormal's API-based approach is less effective against adversary-in-the-middle (AiTM) phishing kits, which have become increasingly popular due to their ability to bypass traditional defenses. The report details how Obsidian Security addresses these challenges with an in-browser solution that stops AiTM phishing attacks by inspecting web content in real-time. It emphasizes the importance of hardening defenses at the browser level to prevent credential theft. The document concludes by suggesting that combining Obsidian Security with existing email security tools can enhance protection against sophisticated identity-targeted attacks.
