Check whether an IP address is associated with a VPN, proxy, Tor, or bot through Focsec’s detection API.
About Focsec
Focsec is a web-based API that checks whether an IP address is associated with a VPN, proxy, Tor network, or bot. Developers send a request with an IP address and an API key, and the service returns data about that address. The homepage states that Focsec tracks more than 300 VPN providers, more than 500,000 free and commercial proxies, and more than 100,000 malicious bots, crawlers and spammers.
The homepage lists several uses in an application: warning users about suspicious logins, preventing fraudulent or multi-account signups, checking whether e-commerce orders are legitimate, and detecting and blocking scrapers and crawlers. Focsec describes its data as near real-time rather than based on outdated blocklists. The source does not describe how detection results should be interpreted or acted on.
