Fastly in Brazil, in numbers
6,524 companies in the LatSouth Brazil Technographics file run Fastly on their public homepage: 1.7% of the 379,761 companies whose verified website shows at least one identifiable technology. The largest share is in São Paulo, and the leading sector is information and communication. By company size: Micro (ME) 3,136, Larger (DEMAIS) 2,117, Small (EPP) 1,255, null 16.
How it is detected: Fastly was seen through an HTTP response header. The scan reads the homepage once, without running JavaScript, so tools that only load inside a tag manager, at checkout or after a click are not counted: treat the number as a floor, not a census.
Each company row in the file carries the CNPJ, legal and trade name, CNAE in English, size, state and city, the verified website and the registry contacts sold in the other Brazil files, plus every technology id, its category, the evidence type and the scan dates.
Seen together with Fastly most often: Google Cloud (Load Balancer / CDN / Firebase) (52.0%), Wix (46.4%), Google Cloud (43.3%), WhatsApp click-to-chat (32.7%), Google Tag Manager (12.9%), GitHub Pages (11.7%), Wix Stores (9.8%), Google Analytics 4 (gtag) (8.5%).

Questions
How does LatSouth know a company uses Fastly?
Its own homepage shows Fastly through an HTTP response header. The fingerprint table is versioned and tested per signature; only the technology id and the evidence type are kept.
Does the file include contacts?
Yes, the company-level contacts sold in the other Brazil files: the registered phone with an accountant flag, the registered e-mail only when it is a role mailbox on the company's own domain, and the verified website. No personal data.
How fresh is it?
The homepages were scanned on 2026-11-03; the company columns come from the Receita Federal release 2026-10-10. A refresh is available on request.
Company data only. Counts are of companies (head-office CNPJ), never of people. LatSouthBot reads each verified homepage once, after its robots.txt, without logging in, filling forms or running JavaScript, and keeps only the technology ids and how they were seen, never the page text. A site that disallows LatSouthBot is not scanned; to opt out, add it to robots.txt or write to hello@latsouth.com. About LatSouthBot · Compliance.
