Obsidian Security's browser extension is a browser-native security tool designed to protect employees from identity threats and data loss occurring within the browser environment. The product addresses security gaps left by traditional tools such as email security gateways and SaaS visibility solutions. It focuses on three primary problem areas: 1. AiTM (Adversary-in-the-Middle) Phishing Detection: Identifies and blocks phishing attacks that bypass email defenses, including modern phishing kits with built-in AiTM capabilities, directly within the browser session. 2. Shadow IT / Shadow SaaS Discovery: Detects unsanctioned applications being accessed by employees through the browser, providing visibility into apps that are otherwise invisible to IT teams but may access sensitive corporate data. 3. Browser-Based Data Loss Prevention: Monitors and prevents data loss occurring through browser activity, covering the channel where employees spend the majority of their working time. The solution is marketed toward mid-market organizations and is used by customers including Snowflake, T-Mobile, Databricks, Pure Storage, Seagate, and S&P Global.
