Get immediate protection against the phishing kits your email security misses, and stop data loss to shadow SaaS and AI apps.

Traditional security solutions lack the ability to protect your employees where they spend most of their time—the browser. This gap allows AiTM phishing attacks and shadow IT applications to evade detection.
Phishing kits now include adversary-in-the-middle (AiTM) capabilities as standard features. Without in-browser protection, attackers can easily bypass your email security.
Stop Common Phishing Kits:
Existing security tools fail to detect every SaaS app your employees are using—even the ones that may access critical data. Without in-browser visibility, your IT and security teams are left in the dark.
Manage Shadow SaaS Applications:
New GenAI apps do a lot of good—but without in-browser visibility or control over who is using these apps, AI may be making your business more risky, not more productive.
Control Unauthorized Use of GenAI:
Get started with detect mode to catch common phishing kits plus build a complete inventory of the SaaS and GenAI apps your employees are using
Obsidian Security’s mid-market solution is specifically built to prevent identity threats and data loss that occur in the browser, where traditional security tools often lack visibility. It detects and blocks advanced spear phishing attacks, manages shadow SaaS applications, and enforces GenAI policies to control and protect your organizational data. The platform also provides instant value with affordable, flexible pricing and fast deployment.
Obsidian uses advanced visual and content analysis within the browser to identify and block adversary-in-the-middle (AiTM) phishing pages, including zero-day spear phishing attacks. It protects users even when threats are delivered to their personal email accounts, surpassing the coverage of standard email security solutions.
Shadow SaaS refers to software-as-a-service applications used by employees without IT’s approval or awareness, potentially exposing sensitive data. Obsidian builds a comprehensive inventory of all SaaS applications accessed in your environment, enabling you to stop data loss from unapproved apps and block access to unsanctioned SaaS.
Obsidian uncovers all GenAI tools and apps in your environment by providing full visibility at the browser layer. The solution allows you to revoke access to unapproved GenAI applications, ensuring sensitive data isn't leaked to risky or unauthorized AI tools.
Obsidian’s solution is deployed as a browser extension compatible with Chromium (enterprise browsers), Chrome, Firefox, and Edge. Deployment is fast, often completed within minutes, and the platform offers automated protection with minimal need for ongoing configuration or maintenance, simplifying management for IT teams.
All analysis and threat detection occur locally within each user's browser, ensuring both privacy and fast performance. No sensitive data is sent externally for analysis, and users experience immediate threat protection without performance degradation.
Obsidian provides affordable and flexible pricing options. There is a free Detect plan for up to 1,000 users that includes app inventory and automated phishing detection. Larger organizations and those seeking active prevention (Warn + Block) can contact Obsidian for tailored solutions that include automated threat blocking and SaaS/GenAI access revocation.
Obsidian works in conjunction with your existing security toolset by providing browser-level visibility and protection that traditional solutions may miss. It requires no complex integration as it operates independently through browser extensions, filling critical gaps in phishing prevention and shadow IT management.
