Best OSINT Tools in 2024: Categories and Reviews

April 15, 2024 · 12 min read

The internet is a goldmine of accessible information, but finding and combining data from various sources can be a daunting task.

That's precisely what OSINT (Open Source Intelligence) tools can do for you. These software solutions are game-changers for businesses, cybersecurity professionals, and investigators who need to mine data at scale.

In this article, we'll introduce you to the seven best OSINT tools, each excelling in its particular niche:

Read on!

What Are OSINT Tools?

OSINT tools help gather publicly available information and scale, as well as harvest and mine data in a way that enables future analysis. They’re indispensable for large organizations with massive data and cybersecurity demands, where manual research and analysis wouldn’t guarantee swift and competitive results.

Types of OSINT Tools

OSINT is a broad term, and so is the OSINT software market. We can divide OSINT tools into the following categories based on their purpose:

Discovery tools

Discovery tools help find new information about the entities of our interest. These may include search engines (yes, in the right hands, Google Search is an OSINT tool, too) or dedicated lookup tools and APIs (e.g., to find phone numbers, addresses, businesses, domains, security threats… the sky’s the limit, as long as the information is publicly available anywhere online).

Scraping tools

Web scraping tools help extract data from the web in a scalable, programmatic, and customizable way (you don’t always need all the information from the given source). With these tools, you’ll gather all the necessary information while avoiding common scraping hurdles, such as bans and blocks.

Aggregation and analysis tools

These tools mine the extracted data to allow for further analysis and processing. Reporting and analytics are often an added functionality of full-scale OSINT solutions, such as Maltego or Babel Street.

OSINT Methods

There are two ways of approaching the intelligence-gathering process when working with OSINT tools:


The passive approach involves the standard search for information using publically available search engines. While this process is the most straightforward and unlikely to provoke detection or blocks, it’s also fairly ineffective. Searches must be performed manually, and it’s hard to drill down on specific subjects of investigation.


This method involves obtaining specific data from a specific target to uncover the most information possible within legal bounds. However, even digging through information readily available through servers and APIs may still be perceived as a security breach attempt and cause a risk of detection and blocking. That’s why it’s crucial to remain anonymous while scraping, e.g., with proxies.

You can also combine the two approaches: use the internet to search for data, with some help from research or scraping software.
