Adding Dark Web Coverage to Your Solutions

The Rise of Darknet Data and APIs

The dark web is roughly 550 times larger than the surface web, yet remains hidden from typical search engines. This secretive data sphere is ripe with potential indicators of compromise (IOCs) and other critical security insights spanning personal information, financial activities, and emergent cyber threats. The IBM® X-Force® Threat Intelligence Index 2024, reports a 7% increase in YoY cyberattacks based on stolen credentials.

Threat intelligence platforms meet these challenges head-on by harnessing the necessary tools for deep web monitoring. However, they depend on a crucial component: vast and continuous data feeds to fuel their analytical engines. This is exactly what dark web APIs deliver, collecting and structuring tens of millions of posts into a format that enhances the accessibility and usability of the data.

When to Use An API Over No-Code UI’s

Most of the companies on this list also offer dark web monitoring platforms – which include a visual interface to immediately query data collected from across the darknet. APIs on the other hand, are necessary when your objective is to feed data into your own solutions. They allow you to customize data streams and adapt data delivery mechanisms to fit your infrastructure.

The APIs featured on this list empower teams to integrate data streams into their own proprietary systems or insights tools such as:

  • Threat intelligence: Dark web APIs facilitate the aggregation of threat intelligence from disparate, clandestine sources, enabling the proactive identification and mitigation of security breaches by integrating real-time threat data directly into cybersecurity platforms.
  • Ecommerce Intelligence: Dark web APIs can enhance fraud detection and prevent transactional fraud by monitoring for stolen financial data and compromised accounts being traded or sold online. This proactive approach not only protects the business but also secures the consumer experience against potential fraud.
  • Financial research and risk management: In the financial sector, dark web APIs are critical in scanning for and mitigating risks related to financial crime, regulatory fraud, and money laundering. By channeling data through sophisticated risk assessment models, these APIs offer quick and precise analyses, significantly enhancing the protection of your organization and clientele against financial threats.

List of APIs to Feed Dark Web Data into Your Own Tools

1. Datastreamer – Easy Integration for Intelligence Products

Datastreamer - API for Dark Web - Example Query (1)

Data feed vendors typically provide a simple method to extract data from their APIs. However, most intelligence products rely on multiple data feeds (typically more than 6). Spending ~5 weeks adding each new API feed adds significant delays in already constrained project timelines. Our comparative analysis revealed that building pipelines in-house for 6 data sources costs upwards of $216,000 in engineering efforts alone (excluding tooling costs). In contrast, plugging in pre-built pipeline infrastructure reduces these costs to just $48,422.

Why Use A Pipeline Platform Instead of Individual APIs

One API Query to Access Darknet Feeds From Different Vendors

Having a single point of access to varied data streams cuts down the engineering workload associated with managing multiple API integrations.

  • Data feeds available include other online sources like social media, news, blogs, and PDF ingestion. 

Improved Signal to Noise Ratio with Advanced NLP

Whichever darknet feed you choose will include millions of posts per month. With most of this being human-generated text, irrelevant noise is inevitable, but can be drastically reduced with natural language processing that is trained to pick up on contextual nuances to reduce missed signals.

  • Instantly deploy NLP models such as location inference, violence detection, or PII redaction.

Built-In Data Engineering Components

Processing enormous data streams cost-effectively requires data engineering components that take months for in-house teams to build out. Market leaders like Black Swan Data use our components to fill in gaps in pipeline infrastructure, keeping their engineers focused on core development for their AI intelligence product.

  • For example: Content deduplication, schema standardization, filtering based on JSON metadata criteria, visual dashboard for debugging.

More benefits of a pipeline platform:

  • Automatically standardize data from different sources (i.e. non dark-web) into a schema that you define.
  • Pre-built destination connectors push data to tools like BigQuery, Snowflake, Databricks.
  • Integrate rapidly by adding data sources to your pipelines in minutes with a drag & drop interface.

2. Dark Owl API
