What to Consider When Choosing a Web Categorization API Vendor

A fundamental requirement of website categorization is accurately classifying websites into relevant categories. But that can be challenging, as the task typically requires targeted web expertise and a multitude of system resources. Therefore, to improve their web categorizing capabilities, large companies and solution providers often need the help of a reliable third-party API.

In this post, we listed the essential considerations when evaluating potential website categorization API providers.

Getting JSON Lines from an API Call into a CSV File via UNIX Command Line

WhoisXML API offers, via API calls, a lot of information on domains or IP addresses that is very useful for a number of applications, including cybersecurity investigations, domain appraisal or system administration. Imagine that one is given a long list of domain names, and one is interested in each domain's details, e.g., WHOIS or website categories, etc. In each API call, a single domain name is sent, and its data is returned in JSON format. (Some of the APIs of WhoisXML API offer bulk lookups, too, but we will not deal with this possibility here.) To get an overview of the data, analysts often prefer to have everything in a single csv file; one line for each domain. This can be opened by popular office spreadsheets like Excel or LibreOffice Calc, or sent to other kinds of processing. 

Top 5 Use Cases of WhoisXML API’s New Website Categorization API

Top 5 Use Cases of WhoisXML API’s New Website Categorization API

WhoisXML API’s website categorization products have been helping organizations determine the authenticity and reliability of sites by scanning the meta tags and content of more than 152 million websites. The machine learning (ML)-driven process allows organizations to detect suspicious domains, align their site categories with their marketing messages, and target the right leads, to name a few.

Today, the tools have been made more massive by adopting the classifications used by the Internet Advertising Bureau (IAB). IAB’s content classification taxonomy has become a standard in the industry, along with other solutions that aim to promote brand safety, ad fraud prevention, and consumer privacy.

Besides the number of categories, Website Categorization Lookup and Website Categorization API also have improved functionalities that provide users with much-needed accuracy and confidence.

Website Categorization Explained - Complete Guide For Your Business

Great attention has been directed lately towards website categorization; a cybersecurity practice which has been around for a while, but it wasn’t until recent times that it started to be increasingly used in marketing and business.

Website categorization is, in essence, the act of putting websites related by their content and function into similar categories. With that in mind, sites like Amazon and Ebay are grouped as Ecommerce sites; CNN, BBC and the likes are classified as news sites; Twitter and Facebook are tagged as social media sites, while Reddit and Quora are Forums (Message Boards) and so on.

However, what some people might not realize is that website categorization is a totally different ball game from Search Engine Optimization and Alexa rankings. Each is different and should be approached in that light - and not be confused.

How to Check & Improve the Reputation of Your Domain

It has never been easier to build a website and online business. You can create a site from scratch and start promoting and selling your product in a matter of hours. Amazing as this is, such convenience also has a dark side. Cyber-criminals can do that just as easily. They can infect your website with malware or mimic its appearance to lure your unsuspecting customers. Running a website became a technically challenging matter: web server software, content management systems and other digital tools all have their vulnerabilities. There are malicious requests impinging at every website in every minute looking for the possibility of taking control over it. One successful attack could destroy your business completely.

Now, the good news. It is possible to measure and improve the reputation of your domain.

All it takes is some knowledge, solid API tools like Domain Reputation and Website Categorization, and a little bit of patience. So, let’s begin!

Using Website Contacts and Categorization Tools for More Effective Digital Rights Management

Digital rights management (DRM) is a systematic approach to copyright protection for all kinds of digital media. It prevents unauthorized redistribution of digital media and stops consumers from copying the content they purchase.

DRM products were developed in response to a rapid rise in online piracy of commercially marketed materials aided by the widespread use of peer-to-peer (P2P) file exchange applications, more widely known as torrent clients.

DRM is typically implemented by embedding code in materials to prevent users from copying them. At times, it limits the amount of time when content can be accessed or the number of devices the media can be consumed on. Despite its widespread use, however, online piracy still runs rampant.

So, what can digital media producers do to protect their intellectual property from online pirates? Would limiting access to their distribution platforms help? How do they make sure that they’re not keeping legitimate consumers out along with the digital pirates? These are just some of the questions that this post answers.

How DNS Filtering and Website Categorization Lists Can Empower In-House Cybersecurity Teams

The IT security climate these days is pretty unpredictable. A study by the University of Maryland states that a security incident occurs every 39 seconds. Companies around the world are, in fact, increasingly suffering from Web-based attacks, not to mention the fact that the average cost of a data breach has skyrocketed.

The good news is that there is a wide range of measures that in-house cybersecurity professionals can employ against threats. One effective solution is Domain Name System (DNS) filtering.

Depending on how it is implemented, DNS filtering can provide advanced network setting controls to enhance online safety. It can protect organizations from threats like botnet, phishing, and other malware-instigated attacks. The great thing about it is that a website categorization database can supplement it. Such a database is thus an excellent resource for managed security service providers (MSSPs) and the like.
