Web Socket Traffic Monitor & Exporter
Summary: PortSwigger lists WebSocket Traffic Monitor & Exporter, a Burp Suite extension by Erinna Anthony at version 1.0.0 and last updated 09 September 2025, for real-time monitoring, capturing and exporting of WebSocket traffic across all Burp tools. It adds tool source tracking, numbered connection organization and CSV export, and lets users right-click WebSocket messages in other Burp tools to send them to a "WebSocket Messages" tab under "Historical Messages" for centralized analysis and export.
Key Takeaway: WebSocket traffic is where session data and commands move after the initial HTTP handshake, and this extension exists to make that traffic capturable and exportable to CSV - so the question for a security leader is whether the same visibility exists in production, not just inside a tester's Burp instance.
