As a credit reference agency we belive rich trusted data is important to make the right decisions and can also be used to detect anomalies and increase sales by delivering better prospecting tools. We continously monitor domains belonging to a business, their subdomains, issued certificates, DNS records and actual content on the pages including usage of payment methods and other services.

​
Domains

We have a distributed large network of crawlers that monitors both zone files for selected domains and certificate transparency entries. Certificate transparency logs contains issued certificates and allows us to detect some of the used subdomains and other important metrics.

​
Certificate Logs

Certificate transparency logs contains the entries for issued certificate which reveals information about subdomains. It can also reveal which companies are using services which can be used for anomaly analysis and prospecting.

DNS records

We monitor DNS records and their changes daily and make it simple to consume anomalies in modifications such as try to hide the destination IP-address by proxying calls.

​
HTML content

In compairsion to traditional web crawling technology that visits web pages periodically and crawls content and links we use a distributed network of headless browsers to simulate real users and allows crawling HTML generated by front-end frameworks such as React, Vue, Svelte, Angular and many more. We also automatically detect front-end APIs and tech stack. Last we also detect usage of Stripe tokens and other payment gateways.

It’s similar to Wayback Machine which is an archive of homepages found on the internet but our method is tailored for anomaly analysis.

​
Social media

We continously search for social media accounts and pages linked to companies such as Facebook, LinkedIn, X, Instagram and many more. We look for example at number of posts, last date of post, reviews which is bundled into anomaly metrics for businesses.

​
Payment gateways

HTML pages leaves tracks of usage of payment gateways which is used to determine how they are used across multiple pages.
