Brandefense Phishing Monitoring is a service that continuously monitors the internet for phishing domains that imitate a brand, with the goal of detecting and initiating takedowns of fraudulent sites. The service monitors across all top-level domains (TLDs) using a combination of advanced heuristics and machine learning to identify domains that impersonate a target brand. When phishing domains are detected, Brandefense works to coordinate their takedown through collaboration with relevant companies and registrars. Beyond simple domain detection, the monitoring scope includes changes to domain attributes such as WHOIS information, MX and A record changes, IP reputation, and SSL certificate updates. These signals are correlated with domain activity to generate broader intelligence on phishing threats. The service aims to protect two areas: customer security (preventing personal information from being submitted to fraudulent sites) and brand reputation (reducing the impact of impersonation campaigns).
