Cisco's threat intelligence team. Has previously returned HTTP 403 on the routine UA (last seen 2026-05-06; recovered 2026-05-07 and confirmed working 2026-05-08). If WebFetch returns 403 again, route through `python3 tools/fetch_source.py url https://blog.talosintelligence.com/` rather than retrying. RSS at /rss/ also works.
