The pros and cons of free OSINT tools

While free OSINT tools are powerful, it’s important to recognize their limitations.

Pros:

• Easy to use with no barrier to entry (free!). This means individuals or small teams can use them just as effectively as large corporations with security budgets.
• Most are open source.
• Virtually endless amounts of tools are consistently being created and improved thanks to community involvement.

Cons:

• Many of these free tools have limited capabilities when compared to their paid versions. API limits, data source restrictions, and cap on usage per day are common.
• Some tools have large amounts of data but may feel clunky to navigate. For beginners getting started with OSINT, this can be frustrating.
• OSINT tools can’t see information that isn’t already available online. Private profiles, paywalled sites, and information hidden behind login portals won’t be found by these tools.

Free OSINT tools allow you to gather as much data as you want from open sources for use in cybersecurity, threat intelligence, journalism, personal research, and more. They might not be as robust or come with as much support as some of the paid products, but they’re still quite useful.

Social media (SOCMINT) is one of the largest OSINT resources. We use social media for everything from identity attribution to behavioral analysis and mapping networks. These tools search and correlate information between the most popular social media platforms (Facebook, X, Instagram, Telegram, Reddit, etc.). Here are some tools that offer great social media coverage:

• ShadowDragon® Horizon® – Great depth of social media coverage. Identity linking and network mapping included.
• theHarvester – Primarily for emails and domains, but useful for pivoting into social account discovery.
• SpiderFoot – Automatically discover social profiles associated with identifiers.
• Recon-ng – Modular framework with some social media plugins.
• Censys – Helps connect technical infrastructure to online identities.
• Shodan – Useful for linking devices or services to individuals or organizations.

The reason these tools are effective for investigating social media is because it’s one of the most fragmented sources of data. You’re able to pivot off of one identifier (email, username, phone, etc.) and discover a network of associated accounts. This ability is what defines SOCMINT-capable tools from just OSINT tools.

Open-source intelligence (OSINT) tools are defined as computer software applications or OSINT platforms, and even OSINT techniques, that can be leveraged for advanced intelligence gathering purposes. Simply put, they’re used to collect publicly available information that can be used for intelligence.

Intelligence professionals utilize a wide variety of specialized tools from each of the different categories when gathering intelligence. These categories include:

• Social media analysis
• Metadata and file forensics
• Domain and IP intelligence
• Geolocation and image verification
• Dark web monitoring

By “advanced intelligence gathering,” we’re referring to the use of OSINT tools to gain deeper insights, connect the dots, and surface actionable intelligence.

When considering what OSINT tool to use for advanced intelligence gathering, you want to look for more than just software that scrapes publicly available data.

You want an OSINT tool that can go deep, scale as you require, and transform massive amounts of raw data into actionable intelligence.

Whether it’s real-time monitoring, advanced analytics, integration, collaboration or compliance, your OSINT tool should be a unified, secure and flexible platform for every step of the intelligence lifecycle.

At a high level, the most important features to consider when selecting the right OSINT tool are:

We’ll go over these features and capabilities in more detail below.

1. Comprehensive coverage

The ideal OSINT platforms will cast the widest net when it comes to covering different sources of data. This includes both physical and digital media, social media platforms, public databases, etc.

2. Data integration and centralization

OSINT platforms should allow you to integrate data from multiple sources and have it centralized in one place.

3. Automation and scalability

Look for a tool that can automate as much of the process as possible and is scalable.

4. Advanced analytics

Machine learning, pattern recognition, and other advanced analytics features are useful for finding additional meaning in your collected data.

5. Actionable insights

A quality OSINT tool should be able to provide insights you can actually use. Simply having data is useless if you aren’t able to turn it into actionable information.

6. Professional-grade

Your tool of choice should be something that’s dependable, supported, and made to get the job done right.

7. Real-time monitoring

A real-time monitoring tool will provide you with the latest information, allowing you to make decisions quickly and get ahead of emerging situations.

8. Visualization and reporting

Translate your collected data into easy-to-read charts, graphs and dashboards with built-in reporting features. Communicate your discoveries more clearly.

9. Cross-platform integration

Integration with other platforms, systems and databases allows your OSINT tool to play nicely with technology from other ecosystems.

10. Multi-language support

If you’re an investigator looking into leads that span the globe, multi-language support will be essential to your investigations. Beyond simply having your tools available in your native language, OSINT tools with multi-language support lift the language barriers around threat intelligence gathering. This allows you to analyze and understand information contained in foreign language sources natively within your tool instead of relying on a separate translator.

11. Anonymity and security

It goes without saying that you want to stay as anonymous and secure as possible when gathering intelligence. The tools you use should have features that prevent your identity and data from being tracked.

12. Customization and flexibility

Different investigators have different workflows, and you want a tool that you can customize to meet your specific needs. Customization and flexibility will allow you to use the tool across different tasks, industries, and types of intelligence without having to overhaul how you normally operate.

13. Collaboration and sharing

Collaboration and sharing tools allow users to work together and share information with colleagues or teams. Look for tools that offer collaboration and sharing features so multiple analysts can work together or share intelligence with different departments.

14. Cost and support

Consider your budget and the level of customer service when selecting OSINT tools. Users should also look into what kind of support is offered in case something goes wrong.

15. Security and compliance

Security and compliance ensure that the tools used for OSINT are secure and follow any applicable laws or regulations, as well as ethical guidelines.

Some OSINT platforms are built as an OSINT search engine. With an OSINT search engine, you can search through indexed data sets and archived snapshots of the internet, going through large volumes of data at lightning-fast speeds.

Other platforms function more as an OSINT people finder. An OSINT people search helps you find people online and connect the dots between their various online identities. The best OSINT people search platforms will pull usernames, social media profiles, email addresses, etc.

ShadowDragon® Horizon® acts as both an OSINT people finder and an OSINT search engine, allowing investigators to search and correlate information for many pieces of data from hundreds of sources, all from a single tool.

A well-rounded open source intelligence workflow requires OSINT tools that complement each other across different investigative phases.
