The most recent check was on October 17, 2026. 1 of the 1 line have been checked so far, from 1 public source.

Each tool is linked to a public page that names Reactor: a vendor's customer page, a published case study, a press release or a job post. We save most pages with a dated capture and check them again on each run. A tool leaves the list only after three checks in a row that no longer find Reactor, and at least 14 days after it was last seen. A tool with a published case study or quote is never removed automatically.
