Open Source Enterprise Browser Security
Citadel is a browser security solution that helps small IT and security teams secure their organization by enforcing IT policy (password, MFA, shadow IT) and detecting data loss, phishing and malware.
Integrate Citadel with a SIEM for situational awareness across your organization—all without compromising user privacy.
Password quality, MFA requirements, device compliance, web filtering, and session duration limits—all managed from one agent.
Malware downloads, blacklisted sites, encryption issues, dangerous browser extensions, and security violations detected in real-time.
Track application usage and identify shadow IT or unused licenses without invasive monitoring of personal browsing.
Only tracks authenticated applications, hashes URLs for forensics, and keeps data local. Designed for GDPR compliance.
Works with any SIEM/XDR that ingests syslog. Pre-integrated with Wazuh. No central server required.
Supports Chrome, Firefox, Edge, Brave, Opera, Arc, Atlas (OpenAI) and Comet (Perplexity). Works on macOS and Windows endpoints.
Citadel includes comprehensive device posture checks that verify your endpoints meet security standards. These controls ensure disk encryption is enabled, systems are updated, firewalls are active, and sensitive data is properly protected.
Users receive clear, actionable guidance when issues are detected—no IT jargon, just step-by-step instructions to fix problems. View all security controls →
