Frequently Asked Questions
Is isMalicious better than IPQualityScore?
They have different focuses. IPQualityScore excels at fraud detection — identifying proxies, VPNs, bots, and disposable emails for account fraud prevention. isMalicious is built for cybersecurity threat intelligence — covering malicious IPs, phishing domains, ransomware infrastructure, CVEs, and dark web exposure. Security teams typically need isMalicious; fraud/anti-abuse teams may prefer IPQS.
Can isMalicious detect VPNs and proxies like IPQualityScore?
isMalicious provides ASN-level context (datacenter vs. residential) and includes VPN and hosting provider signals as part of IP context. For deep proxy/VPN fingerprinting specifically tied to fraud prevention, IPQualityScore provides more granular signals.
Which is better for a SOC team?
isMalicious. SOC teams need threat intelligence covering malware, phishing, ransomware, CVEs, and C2 infrastructure — all of which isMalicious covers. IPQualityScore is optimized for product/fraud teams preventing account abuse rather than security operations teams defending infrastructure.
