IPQualityScore alternative: isIPsafe compared
IPQualityScore (IPQS) is built mainly for fraud prevention, across IP addresses, email, phone numbers, URLs and devices. isipsafe focuses on one thing: addresses reported for attacks. Which you need depends on whether you are stopping fraud or protecting servers.
