When discussing cybersecurity, “darknet monitoring” often conjures images of shadowy marketplaces filled with illicit goods. However, understanding what darknet monitoring truly entails reveals that it is, surprisingly, not predominantly about the darknet itself. Clarifying this confusion requires dissecting the differences among terms like darknet, dark web, and deep web.

Darknet vs. Dark Web vs. Deep Web

• Deep Web: This refers to all web pages not indexed by standard search engines, such as private databases, members-only forums, paywalled sites, and messaging platforms. It is entirely legal and comprises most of the internet.
• Dark Web: Part of the deep web accessible only through specific software like Tor. Although often associated with illicit activities, it also hosts legitimate privacy-focused communications.
• Darknet: Specifically encrypted online networks requiring special software (e.g., Tor, I2P). The darknet is a subset of the dark web, often synonymous in common usage but more accurately referring to the network itself.

Why Organizations Choose Dark Web Monitoring

Organizations engage in “dark web monitoring” primarily to identify exposed sensitive data and credentials that could lead to breaches. This includes sensitive information exposed through various means such as public code repositories (e.g., GitHub leaks), unsecured cloud storage containers (like AWS S3 buckets), URL shorteners inadvertently linking sensitive files, or accidentally indexed internal documentation. Monitoring these exposures is crucial to prevent exploitation of leaked information before malicious actors utilize it in attacks.

However, despite popular perceptions, most sensitive cybersecurity-related data isn’t primarily traded on the darknet.

Where Cybersecurity-Related Data Actually Appears?

Surprisingly, over 90% of cybersecurity-related leaked data surfaces on the deep web rather than traditional darknet marketplaces. While darknet marketplaces mainly trade drugs, weapons, fake documents, or hacking tools, stolen data predominantly circulates in:

• Web forums: Specialized platforms dedicated to particular data types—forums specifically for stolen credit cards, stealer logs, leaked credentials, or compromised databases.
• Telegram channels: Increasingly popular among cybercriminals due to their anonymity, ease of use, and difficulty of monitoring.

Each forum typically specializes in specific data categories, making targeted monitoring essential to detect relevant leaks effectively.

Common Confusion in Dark Web Monitoring

Monitoring practices under the umbrella of “darknet monitoring” often include distinct activities unrelated directly to the darknet itself:

• Attack Surface Monitoring: Using tools like Shodan or Zoomeye, organizations scan publicly available internet-connected assets. While critical, this doesn’t involve darknet activity, instead assessing vulnerabilities exposed openly online.
• Domain Typosquatting Monitoring: Identifies fake websites mimicking legitimate domains to prevent phishing attacks. Although frequently bundled with darknet monitoring solutions, it differs fundamentally as it aims at preventive action rather than reactive identification of leaked data.
• Classical Threat Intelligence:
  • Monitoring ransomware websites: Checking data leak sites maintained by ransomware operators to promptly identify data breaches.
  • Monitoring threat intelligence news: Tracking global security reports and advisories.
  • Subscribing to Indicators of Compromise (IoC): Leveraging known malicious IP addresses, hashes, or domains to proactively protect networks.
• Credential Monitoring: Specifically involves the collection and analysis of leaked credentials, stealer logs, and other sensitive data exposed on forums or messaging channels. This area directly targets compromised user information to prevent unauthorized access. Most data, particularly related to credentials, is actually found on the surface web or within Telegram channels rather than on traditional darknet platforms.
• Social Media Monitoring: Detecting spoofed profiles, attack preparations communicated through social media platforms, or sensitive data exposure caused by employees inadvertently sharing confidential information online.

 

So What Should a Darknet Monitoring Solution Then Really Include?

As more companies face regulatory pressure to demonstrate proactive cyber risk management, the term “darknet monitoring” is thrown around with increasing frequency — and increasing vagueness. Compliance officers may mandate it, CISOs may request quotes, and vendors may bundle it with unrelated services. But what exactly should be included in such a solution? And what’s the difference between bare-minimum compliance and a strategic, intelligence-driven approach?

Let’s unpack this.

The Compliance Use Case: What “Darknet Monitoring” Actually Implies

When a compliance department mandates darknet monitoring, the goal is usually to:

• Identify early indicators of data breaches

• Detect exposure of credentials or sensitive information

• Prove due diligence against regulatory expectations (e.g., GDPR, DORA, NIS2)

In that context, a vendor claiming “dark web intelligence” should not be conflating unrelated surface web services like Shodan scans or SSL monitoring with actual darknet surveillance.

Compliance Standards and Dark Web Monitoring

To meet a compliance-driven darknet monitoring requirement (the minimal viable version), a company should purchase a solution that includes:

1. Credential Leak Detection

• Monitors forums, Telegram channels, and paste sites

• Alerts when company emails, passwords, or tokens are exposed

• Must include both clear/deep and dark web sources

2. Ransomware Leak Site Monitoring

• Tracks victim postings on ransomware group blogs (Tor)

• Alerts if your organization appears on any extortion page

3. Forum/Market Surveillance (Read-only)

• Scrapes known underground forums (e.g. BreachForums, Exploit)

• Keyword matching for company name, domains, employees

4. Compliance Reporting

• PDF or dashboard-based evidence showing:

  • What was monitored

  • When it was scanned

  • What was found

• Timestamped results for audits

Optional but recommended:

• Telegram monitoring (arguably more important than Tor)

The “Rolls Royce” Model: Strategic Threat Intelligence

An optimal darknet monitoring solution goes far beyond checkbox compliance. It becomes an integral part of a broader Threat Exposure Management and Brand Protection strategy.

These are not strictly darknet-related, but in a unified threat intelligence platform, they make sense. The key is that the vendor should be transparent about what is dark web vs. surface web.

Final Recommendation

If you’re buying darknet monitoring because “compliance requires it,” don’t get sold a kitchen sink.

Ask for:

• A source list (Tor, Telegram, forums, etc.)

• Example alerts from real past leaks

• Distinction between surface/deep/dark sources

• Proof of monitoring — not just marketing slides

And if you’re ready to go beyond compliance into proactive risk detection, then look for a solution that:

• • Automates stealer log parsing

  • Detects patterns of targeting against your sector

  • Gives you early warning of threat actors circling your environment
