IP reputation analysis API allows businesses to detect potentially malicious IP addresses known for spam or fraudulent activities like phishing, hacking and other cybercrime. They can reduce fake sign-ups on websites, protect web forms and gain valuable insights such as if an IP address is used as proxy or if it has been blocked by a variety of blacklist services.

An IP’s reputation score can be damaged by bad behaviors such as erratic email volume, high bounce rates or repeated spam complaints. Additionally, a poorly performing network can cause ISPs to block emails, or trigger penalties from ad networks. A strong reputation requires consistent monitoring, best practices and the right tools.

IP Reputation Analysis API: Score and Monitor Risk in Real-Time

Using a reputation API allows you to check an IP’s status on multiple blacklists, identify if it is a known proxy or VPN, and determine the location of the IP in real-time. It also provides a risk score, ranging from 0-100 based on multiple factors including whether the IP is blacklisted or not.

The Prowl IP Reputation API service runs behind the scenes to collect, process and redistribute reputation intelligence for vast numbers of IP addresses. The reputation data is gathered from trusted sources, including multiple global sensor networks, and analyzed for specific signals that are tracked and ranked by experienced researchers. The data is then shared with a hub which in turn distributes the intelligence to individual sensors. This enables sensors to act upon the threat intelligence in their own security systems in a secure and automated manner.
