What is IP reputation?
IP reputation is enrichment on the network address of an event—geolocation, hosting vs residential, VPN/proxy likelihood, and whether the IP was previously tied to abuse.
What it is good for
Naiza enriches events with IP geolocation and VPN/proxy detection. Combine network context with device and customer history to review credential-stuffing bursts and unusual access patterns.
Combine network and device signals
Corporate VPNs and mobile carrier NAT share one address across many real customers. Naiza pairs IP reputation with device fingerprint and customer history instead of blocking whole countries or every VPN user.
How Naiza applies it
Naiza carries IP context into rules and scoring and supports lists for confirmed abusive IPs. Connect IP, device, and customer identifiers so investigators can review the event together.
Frequently asked questions
Answers about screening, risk signals, and Naiza integration.
What is an IP reputation API?
It returns risk attributes for an IP so your fraud rules can treat datacenter, proxy, or previously abusive addresses differently from typical residential traffic.
Should we block all VPN IPs?
No. REVIEW or step-up is safer. Many legitimate users travel on VPNs. Block listed IPs with a confirmed abuse history.
Is IP enough to stop ATO?
No. Attackers rotate IPs. Device fingerprints and login velocity still matter. Read device intelligence vs IP-only.
