Linking and the companion file
The home page of tenable.com does not link the file in its HTML. Ora's lab found (2026-10-19) that 86 percent of llms.txt fetches by agents arrived through a link, so an unlinked file is mostly a file nobody opens. No llms-full.txt was found at the same root.
How it compares
At 8.7 KB the file is larger than 54 percent of the 2,529 plain-text llms.txt files in this edition, and its 54 links put it ahead of 63 percent of them on link count. The home page declares no generator. Size bucket: 2 to 10 KB. Tranco rank 2,622. Category: Security.
