How this list is built
Live scans look for current evidence that a company holds an account with the service, rather than a tag on the company's website or a service named in a job ad. That is why anVendor finds SaaS used behind a login. It never touches private, password-protected or access-restricted systems, and uses no browser extension, SDK or tracking script.
Where a vendor's service offers no public sign, we report nothing rather than guess — so a company missing from this page means no evidence found, not not a customer. A company we stop finding drops out of the list rather than sitting on it forever.
