CISOs Face Critical Decisions on Costs and Benefits of Dark Web Monitoring

Dark web monitoring has emerged as a crucial tool for enterprise cybersecurity teams, providing them with early warnings of potential attacks and alerts regarding exposed corporate data and credentials. This proactive approach allows organizations to anticipate incoming threats and identify vulnerable systems and users, enabling them to implement defense strategies before incidents occur.

For instance, a company that discovers through dark web monitoring that an infostealer has been installed on an employee’s computer can take immediate action. The security team might deploy various defensive measures, such as setting up a honeypot to trap the hacker or reimaging the compromised computer to tighten security configurations. Conversely, if the organization remains unaware until stolen credentials are used to access core systems and extract sensitive data, their options become severely limited, and the damage may already be irreversible.

However, dark web monitoring is not universally beneficial for all organizations. Chief Information Security Officers (CISOs) must carefully evaluate the costs and risks associated with this practice. While some large and high-profile organizations may find significant value in dark web monitoring, others may determine that their resources could be better allocated elsewhere.

Limitations, Costs, and Risks of Dark Web Monitoring

Despite the potential advantages, dark web monitoring has notable limitations. One primary constraint is that it can only reveal information that threat actors choose to post. If a malicious hacker intends to breach an organization’s networks or applications without publicizing their plans, dark web monitoring will not provide any insights.

Another significant challenge, particularly for organizations conducting their own dark web monitoring, is the sheer volume of places to search. New sites continually emerge, many of which do not advertise their existence, complicating the monitoring process.

In-House Dark Web Monitoring vs. Third-Party Services

Organizations opting for in-house dark web monitoring face a choice: either invest substantial time and resources into the initiative or risk inadequate monitoring. This approach often necessitates the acquisition of specialized tools such as Maltego or Spiderfoot, along with the development of staff expertise in open-source tools like TorBot or OnionScan.

In-house monitoring also requires programming automated scans and alerts, as well as integrating threat intelligence with other cybersecurity platforms, including security information and event management (SIEM) systems and endpoint detection and response (EDR) solutions.

Alternatively, engaging a third-party threat intelligence service for dark web monitoring can alleviate the burden on in-house cybersecurity teams. However, this option comes with its own costs and necessitates careful selection of a managed service provider to ensure flexibility and responsiveness to customer needs.

Utilizing a third-party service also mitigates the risks associated with gathering firsthand threat intelligence in potentially illegal environments. In-house teams may inadvertently expose themselves to malicious threats, whereas third-party services can provide a buffer against such risks.

Is Dark Web Monitoring Worth It?

For smaller organizations, the costs and risks associated with dark web monitoring often outweigh the benefits. As organizations grow in size and prominence, the value of such monitoring increases. For many companies, leveraging a third-party service is more practical, conserving cybersecurity personnel’s time and reducing the risk of drawing unwanted attention while monitoring for threats.

Organizations considering in-house dark web monitoring typically possess certain characteristics:

• Well-trained cybersecurity teams capable of dedicating significant time and effort to the initiative.
• A high profile that minimizes the risk of becoming greater targets by actively seeking out threats.

What to Monitor on the Dark Web

For security teams that determine dark web monitoring is worthwhile, there are several key areas to focus on:

• Compromised Credentials: Credentials on the dark web can originate from various sources, including spyware, phishing attacks, or even physical theft. Some credentials may be part of large data breaches, while others could be isolated incidents. It is important to note that some credentials found on the dark web may be speculative rather than verified.

• Zero-Day Vulnerabilities: Malicious hackers may post or sell exploitable vulnerabilities in software packages, providing insights into potential threats.

• Company-Specific Vulnerabilities: A hacker who breaches an organization can gather extensive information about its defenses and weaknesses, which may then be sold to other attackers.

• Previews of Stolen Information: Attackers often post samples of stolen data to auction it off or pressure organizations into paying ransoms.

• Insider Threats: Certain dark web forums cater to disgruntled employees looking to sell access or information related to their organizations.

• Phishing Kits: Cybercriminals can easily acquire ready-to-use kits to create fraudulent websites that mimic legitimate company portals.

• Phishing Sites: Dark web monitoring can help identify fraudulent sites that closely resemble legitimate organizations, posing a risk to unsuspecting users.

Where to Look on the Dark Web

The dark web consists of various sites that serve different purposes, from forums discussing attack methodologies to marketplaces for stolen data and credentials. Some sites, like exploit.in and BreachForums, are relatively easy to find and monitor, although the latter was shut down by law enforcement in 2025. However, such sites often reappear after being taken offline.

Many dark web sites are hidden behind TOR networks, making them difficult to access. Additionally, secure messaging platforms like Telegram are increasingly becoming popular venues for cybercriminals, with thousands of channels dedicated to selling stolen information.
