A Comprehensive Guide to Geolocation APIs for Cybersecurity Professionals

Geolocation has long been linked to business. In fact, the ability to know the physical location of a person or network entity based on the information behind its IP address is a key feature that organizations have been leveraging for some time now. Is that really so? You have probably come across a few by-products of this technology whether you noticed it or not in your daily life — e.g., location-aware apps, targeted advertisements, and customized e-commerce content. However, IP geolocation is not only about online sales and advertising. Cybersecurity is another sector that can strongly benefit from its capabilities, notably to keep track of cybercriminals’ activities and their whereabouts for better threat detection and prevention. This article takes an in-depth look at the best IP geolocation APIs out there with screenshots for cybersecurity professionals and provides an overview of what these products have to offer. But before getting to that, let’s first review why geolocation is so relevant for running adequate cybersecurity operations nowadays and the important criteria you need to select the right product. Table of contents: The relevance of IP geolocation for cybersecurity Criteria for choosing an IP geolocation API Understanding the product landscape Provider 1: geoipify.whoisxmlapi.com Provider 2: geo.ipify.org Provider 3: IPInfo.io Provider 4: DB-IP.com Provider 5: IP2Location.com Provider 6: IPData.co Provider 7: IPGeolocation.io Provider 8: Ipapi.com Provider 9: IPStack.com Provider 10: ClearIP.io Provider 11: IPWhois.io Concluding thoughts The Relevance of IP Geolocation for Cybersecurity Why would you want to get started with an IP geolocation API? It’s no secret that the current digital landscape is harsh with restless malicious entities and cyberattacks that continually hit businesses, systems, and users. From the hacking of corporate networks and stealing and selling of sensitive information on black markets to data breaches that affect not only the online but also the physical wellbeing of people, attacks continue to grow in scope and put everyone’s activities online at risk. With the objective of preventing and stopping these harmful acts, several types of cybersecurity professionals — including threat hunters, incident response specialists, penetration testing experts, and cybersecurity analysts — find geolocation handy. So how can the technology give an edge more specifically? By performing a lookup on a certain IP address, geolocation data can supply experts with crucial indicators to verify dubious entities on the Internet as the information disclosed about a person or organization behind a device includes the city, country, state, time zone, coordinates, and more. Use cases of IP geolocation in cybersecurity There are many applications for IP geolocation in cybersecurity today. For instance, geodata can be used in dealing with intruders who have found a way to enter a company’s network. One method of accomplishing this is by cross-examining current geolocation details of suspicious remote users and visitors to unveil irregularities in profile information. If a mismatch has been confirmed and a trespasser is discovered, restrictions can then be implemented to stop further access to sensitive data or applications. Figuring out the entry point of a cyberattack is something that has always been a challenge in the industry as it is. The good news is that since IP geolocation APIs take into account the coordinates of users, they can be employed to trace back where a threat is coming from and identify its source of action. From there, specialists can decide to apply threat intelligence techniques to map out other entities connected to the target and highlight possibly malicious associates. Knowing the origins of an act of cybercrime is also important because it gives solid proof to perform further analysis. Once these threats have been verified, professionals can carry out counterattacks to impede and stop them from causing more harm. Additionally, they can use the data from IP geolocation to cross-link verified intrusions with traffic information that can be verified. Another way that this technology can be employed is in combating online fraud and identity theft which cause staggering financial losses each year and affect millions of individuals worldwide. Indeed, stolen credit card information is among the most common consequences whenever data breaches occur. IP geolocation can help here as it allows cybersecurity experts to compare suspect IP addresses with past billing details of legitimate customers. Any discrepancy that is revealed at this stage — especially when orders are made from questionable locations — can then be flagged for a more in-depth review. IP geolocation can also be leveraged to stay protected from spam or suspicious mail. To check whether a message is sent by the real person or not, cybersecurity personnel can perform geo IP searches to gather and analyze all sorts of location-based data on users. This feature enables the geo-blocking of certain IP addresses coming from places that are considered to be high risk. This reduces the probability of dangerous emails reaching the organization, and thus minimizes vulnerabilities. Criteria for Choosing an IP Geolocation API “One size fits all” does not exist with this product category. Instead, cybersecurity professionals need to select an IP geolocation API in a wise way as not all the products on the market are equal. There are several aspects which you need to consider among which the ones below: 1. Coverage First things first, it’s crucial to know what coverage a solution offers to its clients — that is the number of IP addresses under scrutiny and monitored for a given region, country, etc. and the accuracy level. That matters for cybersecurity applications which rely on precision and timeliness for counteracting cybercriminals from different places. Therefore, it’s important to account for the fact that some IP geolocation providers specialize in supplying accurate information for locations in the US while others might do so in Europe or other regions. 2. Compatibility Most organizations typically plan to integrate an IP geolocation API with their new or existing security systems. This means that specialists need to consider which programming languages are supported, whether the databases are available in different formats, and if standardized responses can be enabled — allowing for streamlined operations and saving precious time while dealing with cybersecurity threats. 3. Reliability Cybersecurity experts should also know how trustworthy an API might be before committing time and money into it. Some factors to consider in terms of reliability can include response time, how often the software experiences unavailability, and if customer service teams can provide prompt support. Constant and easy access to all services is another crucial aspect to bear in mind as cybersecurity specialists are expected to respond immediately to threat events. 4. Documentation Lastly, the documentation offered by a provider is another key criterion. These files provide assistance in getting started, teach how to use features, explain how to address issues, and contain other tips and tricks. This material can be presented as user guides, instruction manuals, or FAQs. Understanding the Product Landscape As mentioned earlier, not all IP geolocation APIs are from the same breed. Some might focus on providing data variety, whereas others have fewer but more accurate output fields. What’s more, some solutions offer functionality that cybersecurity specialists will find useful while other products may be more suited to other professions and use cases. For instance, certain cybersecurity tasks don’t necessitate getting details on a target address like a suspect’s ZIP code but require accurate latitude and longitude information. Another example is when experts may not be interested in the timezone of the target but might want to learn about the organization and the ISP behind the IP address to run an investigation. Aside from that, some providers offer complementary services such as access to a WHOIS database download service or threat intelligence analysis, which, when combined with IP geolocation data, can help strengthen and streamline cybersecurity operations. With a better understanding of the current product landscape, here is a non-exhaustive list of the major IP geolocation providers for you to check out. Provider 1: ip-geolocation.whoisxmlapi.com/api Coverage WhoisXML API gathers its data from numerous entities which it has legal agreements established with. Among their sources are major ISPs who are already familiar with the IPs they own and allocate and can provide more precise data on corresponding networks and devices if necessary. This process often translates to more comprehensive results and higher IP geolocation accuracy compared with that offered by other platforms and services. The company claims to cover 99.05% of the IP space today, which includes both IPv4 and IPv6 addresses. Its output includes country, region, city, postal code, latitude and longitude, postal code, timezone, an array of domains associated with an IP, as well as the data on the Autonomous System for IPv4. In terms of recently-added functionality, the API’s Autonomous System Number (ASN) type feature lets users determine the kind of network an IP address belongs to. In other words, this is a unique identifier, which allows an autonomous system to exchange routing data with other systems. Results that can show up here include digital subscriber line (DSL), content, educational, enterprise, and more. Other new features such as GeoName ID tagging, meanwhile, assigns a location identifier for any given IP address. The tags are based on the GeoNames database, a repository of geographical data from all countries. This database also has more than 11 million place names available. When performing a lookup, the API automatically queries the GeoNames database for an IP’s unique geographical identifier. The API also has a built-in associated domains parameter, which allows users to see all of the domains connected to a specific IP address. It does this by identifying all of the known websites that it detects and provides this in a list. This list can be particularly handy in recognizing other domains that are being operated by a particular individual or organization. With regards to its records, Whois XML API keeps all of these stored in a regularly updated database. More than 8 million IP blocks and locations are available with the service. Additionally, the site provides bulk lookups and download facilities which can be quite helpful, for instance, when a large number of suspicious addresses needs to be reviewed simultaneously at once rather than manually one by one.
