About Obsidian Security
Obsidian Security provides security for third-party applications and AI agents. Its platform gives visibility, governance and runtime controls over identities, integrations and agents across business apps. It collects signals from apps, browsers and threat data to find misconfigurations and risky activity. The company sells to large enterprises, including Fortune 1000 and Global 2000 firms. It also offers an AI assistant for security teams and a trust centre for compliance documents. The platform aims to protect data that users and AI agents access in third-party apps.
