Least-privilege permissions

• Restrict system access: Run the connector with minimal user permissions—never as administrator or root. Treat it like a limited employee account that can only access specific folders and services.
• Separate credentials: Never reuse production passwords, API keys, or login tokens. Create isolated test accounts with expiring access that are deleted after each inspection session.
• Limit browser scope: If using the Chrome debugging feature, whitelist only specific websites or internal domains that need inspection—block access to financial systems, customer databases, or internal admin panels by default.
• Disable anti-detection by default: Keep Patchright and CloakBrowser disabled unless explicitly needed; only enable them for legitimate testing with documented approval from your legal/compliance team.

Network isolation

• Air-gap testing environments: Run the connector only on isolated test networks that cannot reach production systems, customer data, or the public internet without explicit routing rules.
• Firewall blocking: Use network firewalls to prevent the connector from initiating outbound connections to external services; allow only connections to your approved testing infrastructure.
• Monitor data exfiltration: Disable USB drives, cloud sync, and file sharing on machines running this tool to prevent captured credentials or session data from leaving the network.

Monitoring

• Audit all inspection activity: Log every website, API call, and data capture the connector performs; review logs weekly for unexpected targets (production systems, competitor sites, financial platforms).
• Alert on credential patterns: Set up automated alerts if the connector captures authentication tokens, API keys, passwords, or session cookies; escalate immediately to security team.
• Track tool usage: Record who launched the connector, when, what they inspected, and for how long; tie this to business tickets or project codes for accountability.

Red flags to watch for

• Targeting production systems: Anyone attempting to point the connector at live customer databases, payment systems, or employee platforms without explicit security review approval.
• Reverse-engineering third-party services: Using the tool to inspect or bypass security on external companies' websites or APIs you don't own—this may violate laws like the Computer Fraud and Abuse Act.
• Persistence or automation: Scripts that run the connector repeatedly or automatically against systems without human oversight or documented business justification.
• Disabled monitoring or logs: Users disabling audit logs, clearing browser history, or requesting "stealth mode"—legitimate testing should always leave an audit trail.
