Anura Definitions - Rule Sets

To make accurate judgements on website visitor quality, Anura has a series of rules that power the decision-making process. Each of Anura's seven rule sets are comprised of multiple rules that work together to ensure accuracy.

Data Integrity

Anura analyzes data that we have collected about the visitor to provide responses regarding their quality. During the process, data is collected and data integrity is insured. The purpose is to provide accurate and consistent data over the life-cycle of the session. This information must remain fully in-tact without any alteration of data. If Anura detects any data inconsistencies, it will trigger one or more of the rules within this rule set.

User Environment

Anura analyzes and identifies abnormalities within the visitor's device. With that information, Anura additionally checks against known identifiers of bot/malicious activities.

Data Center

A data center is a facility that houses remote storage of data, web servers, and servers, all which aid in powering the internet. While data centers are paramount in most networks' critical systems, and are vital to daily operations, they do not typically generate website visitors. Anura routinely checks and verifies using in-house proprietary methods to ensure the visitor is not coming from a data center.

Traffic Origin

The flow of visitors across the internet generates data which tells us where the visitor has been prior to visiting your website. With the information gathered, Anura reviews prior origin data to determine if it has come from a known fraudulent site, or if it gives indications of questionable origination.

IP Integrity

An IP address is like a physical address - multiple people may use the same address. Sometimes IP addresses can be compromised and used to do offensive work across the internet. Using Anura's own proprietary IP offender list, Anura then validates the visitor's IP address for integrity.


Internet spoofing is pretending to be someone or something you're not. Anura has a series of rules designed to validate whether a visitor is genuine or spoofed.

Web Crawler

Web crawlers are internet bots that scour the web with the purpose of indexing the contents of websites. Legitimate websites, such as search engines, use web crawlers to provide the most up-to-date information available on the web. Using both public and private lists, Anura checks to make sure the visitor is not a known web crawler such as Googlebot.
