When companies sign up for SaaS platforms, those vendors often ask them to add a TXT record to their DNS to prove domain ownership. This creates a passive fingerprint of the technology stack a domain is using. This tool queries all TXT records for a domain and matches them against a database of known vendor verification patterns.
Security teams use this for vendor risk assessment and supply chain analysis. Sales teams use it to understand what tools a prospect uses before reaching out. IT admins use it to audit their own domain's authorised vendors. Penetration testers use it as an OSINT data point during reconnaissance.
