Obsidian Security has introduced a cutting-edge browser extension designed to help businesses safely navigate SaaS and AI applications online. The extension actively identifies and manages shadow SaaS and AI tools, blocks sophisticated spear-phishing attacks targeting access tokens, and delivers real-time protection directly in users’ browsers. Lightweight, fast, and privacy-first, the solution already protects over a million devices across 200 large and mid-sized enterprise clients. By leveraging Obsidian’s extensive network insights and threat research, the extension continuously adapts to block emerging threats as they appear.

This launch holds particular significance for mid-sized enterprises, which often operate with limited security resources. Obsidian’s browser extension requires minimal deployment effort and provides robust Shadow SaaS/AI visibility and threat prevention without complex management or heavy configuration. As a result, teams can eliminate web risks and reduce unnecessary costs associated with unauthorized SaaS usage.

The extension automatically detects and tracks both known and previously unknown apps across popular workforce browsers, including Chrome, Firefox, and enterprise platforms like Island. Security teams gain immediate insights into unfederated authentication and potential SaaS data exposure caused by supply chain breaches. Consequently, businesses can adopt emerging technologies safely, monitor app usage against IT-approved lists, and block access to high-risk AI and SaaS applications before they compromise operations.

The threat landscape has evolved, with phishing kits now posing a major risk to SaaS. Attackers increasingly use AI to craft fake login pages that replicate legitimate platforms down to the last pixel, tricking users into exposing access tokens. These tokens can then be exploited to access enterprise SaaS applications. Known as Adversary-in-the-Middle (AitM) attacks, these methods bypass multi-factor authentication and even two layers of email protection in 90% of enterprise scenarios. Obsidian Security’s browser extension stops SaaS token theft in real time by identifying and blocking actions on fraudulent login pages. Through AI-driven visual and content analysis, it detects and neutralizes threats while continuously learning from incident response to prevent future attacks.

“Obsidian recognizes that SaaS Security is a journey, and the primary needs of mid-market enterprises differ from large enterprises. With Obsidian, growing enterprises can start with a prevention-focused solution delivered as a light-weight browser extension. When ready, they will expand to cover additional use cases spanning SaaS Security Posture Management, and Identity Threat Detection and Response, all without needing a new vendor,” said Obsidian CEO, Hasan Imam.

By combining proactive detection, AI-driven protection, and easy deployment, Obsidian Security’s browser extension empowers organizations to embrace innovation while keeping SaaS and AI environments safe and cost-effective.
