PhishTank is a community-driven anti-phishing platform operated by Cisco Talos Intelligence Group. Originally created by the OpenDNS team, the platform allows users to submit suspected phishing emails and websites for community review and verification. The platform operates on an open model, meaning that the phishing data collected and verified by the community is made publicly accessible. A core feature of PhishTank is its free API, which enables developers and organizations to integrate phishing detection capabilities directly into their own applications and services using community-sourced data. PhishTank's model relies on crowdsourced intelligence: community members submit phishing URLs and emails, which are then reviewed and validated by other users, creating a collaboratively maintained database of confirmed phishing sites. This data can be used by security researchers, developers, and organizations to identify and block phishing threats. The platform is now maintained under Cisco Talos Intelligence Group, Cisco's threat intelligence organization, which provides additional institutional backing to the community data and infrastructure. PhishTank primarily serves developers, security researchers, and organizations looking to enrich their security tools and workflows with verified phishing threat data.
