When it comes to cybersecurity threats, few risks are as quietly dangerous as leaked credentials—and few places are as effective at distributing them as the dark web.
Many threat actors use the dark web to share attack methods and trade compromised data, including personally identifiable information and intellectual property.
Unlike the common internet most people interact with, the dark web is a hidden layer of the internet where stolen data is bought, sold, and shared in real time. From employee logins and administrator credentials to entire domain email dumps, these underground marketplaces thrive on corporate information—and your organization might already be listed without your knowledge.
So, what is dark web monitoring? At its core, it’s the practice of scanning dark web forums, data dumps, and breach repositories to detect when your business’s sensitive data has been exposed. It helps organizations detect when their company's data or organization's information, such as bank accounts or sensitive intellectual property, appears on the dark web. By setting up monitoring systems, IT teams can receive alerts when emails, passwords, or other identifiers appear in known breaches—sometimes even before the leak is publicly disclosed.
Why do you need dark web alerts? Because compromised credentials are often the first step in a broader attack. Phishing attacks and data breaches often begin with compromised data found on the dark web, and monitoring helps identify potential threats before they escalate. Phishing, account takeovers, ransomware campaigns—they all begin with stolen access. The earlier you detect a breach, the better your chances of stopping damage before it spreads.
TL;DR
- Dark web monitoring helps detect compromised company emails and credentials before damage is done.
- You’ll need the right tools, alert setup, and integration with your security workflows.
- Prey’s Breach Monitoring provides early alerts, actionable severity scores, and works without device agents.
- Start protecting your organization from silent breaches today.
Step 1 – Identify what needs monitoring
The first step in setting up effective dark web monitoring is knowing what to track. This might sound obvious, but many organizations focus too narrowly—monitoring only a few executive emails while overlooking other high-risk entry points.
At minimum, you should monitor your business email domain and all individual employee addresses tied to sensitive systems. Company emails are often the easiest way for attackers to gain access to internal platforms, especially if credentials are reused or not protected with multi-factor authentication.
Start with C-suite executives and IT administrators, as these accounts typically have elevated access privileges. These are prime targets for attackers looking to escalate quickly once inside a network. But don’t stop there. Sales reps, HR teams, and even interns may use tools that hold valuable data—or could be leveraged in phishing campaigns.
You should also consider third-party contractors, former employees, or inactive accounts still tied to your systems. These often fall through the cracks but can remain vulnerable if not properly decommissioned.
When deciding what to monitor, include not just email addresses but also sensitive data such as bank accounts, personally identifiable information, and intellectual property. Monitoring these types of data helps protect your organization from unauthorized transactions, data theft, and exposure of proprietary assets.
A helpful approach is to run a full domain scan to catch any associated email addresses—even those you may have missed manually. This ensures broader visibility and early detection of breaches before they spread, and helps detect compromised data beyond just email addresses.
Prey allows you to monitor either full domains or specific emails—making it flexible for companies of any size, whether you’re securing a small remote team or an entire enterprise network.
Step 2 – Choose the right dark web monitoring tool
Once you know what needs to be monitored, the next step is choosing the right dark web monitoring tool to get the job done effectively. For organizations seeking to protect their data, a dark web monitor or dark web monitoring service is essential, as it helps detect data breaches, monitor illicit activity, and provide early threat alerts. While there are plenty of dark web monitoring tools available, not all of them are built with businesses in mind—and even fewer integrate smoothly into enterprise security workflows.
So what makes the best dark web monitoring software stand out? Here’s what to look for:
- Continuous scanning: Real threats don’t wait for weekly checks. Your tool should scan breach databases and dark web forums in near real-time, flagging exposures as soon as they appear. Dark web monitoring work involves using automated tools and sometimes a dark web search engine to continuously scan for sensitive or leaked information.
- Alert system with severity scoring: Not all leaks are equal. The best tools provide prioritized alerts that help security teams focus on the most critical exposures—like plaintext passwords or credentials tied to admin accounts—so you can act fast.
- Exportable data for audits or SIEM integration: Your security team needs to be able to dig into the data, share it across systems, and feed it into existing incident response workflows. Integration with security platforms is important for a seamless workflow.
- Transparent, trustworthy sources: Whether it’s public breaches, underground marketplaces, or hacker forums, you need visibility into where the data came from—and how recent it is.
Manual search vs. automated monitoring
Manual searches or free scan tools might help in isolated cases, but they’re not designed for enterprise use. They miss emerging threats, can’t scale across departments, and leave you reacting too late. Instead of having to manually search each dark web site for relevant keywords, analysts can use a dark web search engine to streamline the process and improve efficiency.
It’s also important to note that endpoint security tools aren’t enough. While they protect devices, they don’t monitor for identity leaks—meaning your credentials could be for sale on the dark web even if your systems are fully patched and secure.
Prey’s Breach Monitoring checks all the boxes. It offers continuous scanning, severity-based alerts, raw data exports, and full domain coverage—all in a lightweight, easy-to-deploy platform designed for growing organizations.
Step 3 – Set up alerts and severity scoring
Once your monitoring tool is in place, the next critical step is configuring dark web alerts to ensure your team can respond quickly and efficiently when threats are detected. Prioritized alerts help teams respond quickly to the most significant potential threats, ensuring that security resources are focused where they are needed most. Without a well-defined alert system, even the best monitoring tool won’t deliver the value your organization needs.
Alerts should be triggered when data appears on the dark web, so your team is immediately notified of any compromised credentials or sensitive information.
How to configure alerts
Start by setting severity levels that reflect the type of credential leak or data exposure identified. For example:
- Critical: Plaintext passwords, admin credentials, or multiple employee exposures in a single breach
- High: Hashed passwords, credentials associated with elevated access
- Low: Old or inactive accounts, duplicates, or breaches with partial data only
You should also define the frequency of alerts. Real-time or daily alerts may be necessary for large organizations, while weekly summaries may be sufficient for smaller teams with lower risk profiles.
Who gets notified
Not every alert should go to everyone. Establish an internal notification structure so the right people get the right information:
- IT and SysAdmin teams: Day-to-day monitoring and remediation
- CISOs or Security Leads: Oversight and escalation of high-severity breaches
- SOC teams or Managed Security Providers: Triage and incident response execution
This prevents alert fatigue and ensures faster reactions to the exposures that matter most.
How to interpret severity
Not all credential leaks carry the same level of risk. For instance:
- A plaintext password tied to a domain admin account = immediate threat
- A hashed password from a 5-year-old breach = lower priority, but still needs review
- A reused password flagged in multiple breaches = time for a policy update
Understanding these differences helps prioritize your response and allocate security resources effectively.
Escalation and response workflows
Once alerts are triggered, your organization should have a clear process to follow. This might include:
- Verifying exposure
- Notifying impacted users
- Forcing password resets
- Implementing or re-enforcing MFA
- Logging incidents for compliance or audit trails
Prey delivers weekly reports with clear severity scoring and flags Critical alerts, giving your team early warnings and actionable insights—before those leaked credentials become entry points for attackers.
Step 4 – Integrate monitoring with your security stack
Detecting credential leaks is only part of the job—what happens next is what truly protects your organization. Integrating dark web monitoring with your security platforms is essential for a comprehensive overall security strategy, ensuring that your organization proactively addresses threats from all angles. That’s why it’s essential to integrate dark web monitoring with your existing security infrastructure, especially tools like SIEMs (Security Information and Event Management systems) and SOC workflows. Monitoring both the internet and dark web provides a more complete view of threats, enabling your team to respond quickly and effectively.
Centralize your alerts for faster response
Too often, breach notifications live in silos—buried in inboxes or stuck in vendor dashboards. To make dark web monitoring part of your broader incident response, it needs to be integrated into the systems your security team already uses.
When dark web alerts feed directly into your SIEM platform, they become part of your centralized log and detection environment. This enables:
- Correlation with other threat signals (e.g., unusual login attempts from the same account)
- Faster escalation and triage
- Unified visibility across tools and teams
Example integration methods
Most modern monitoring tools provide multiple ways to sync alerts with your stack. Look for options like:
- Exportable CSVs for manual upload or internal audit logging
- APIs for custom integrations into SOC dashboards
- Auto-tagging and metadata to flag breach context in your response platform
- Webhook or email-based forwarding to specific distribution lists or ticketing systems
Even simple exports can make a difference when added to your SIEM’s intake pipeline.
From exposure to resolution: what the workflow looks like
A strong integration ensures you’re not just receiving alerts—you’re acting on them. Here’s a typical remediation flow:
By mapping out this process, you ensure no exposure falls through the cracks—and your team knows exactly what to do when an alert comes in.
Prey makes this easy with raw data exports, structured reports, and compatibility with a wide range of security tools. Whether you’re working with a lean IT team or a full-scale SOC, Prey’s breach monitoring complements your stack without adding complexity.
Step 5 – Act on the findings and improve over time
Once you’ve detected a potential exposure, especially if compromised data is identified, it’s critical to act swiftly and strategically. Knowing what to do if employee data is on the dark web can mean the difference between containing a breach and letting it escalate into a full-blown incident.
Best practices for responding to dark web exposure
- Rotate passwords immediately
Any exposed account—especially those with privileged access—should have its password reset without delay. Don’t wait for signs of misuse. - Enforce multi-factor authentication (MFA)
If MFA isn’t already enabled across your organization, now’s the time. Even leaked passwords lose value when they’re backed up by a second authentication factor. - Communicate securely with affected users
Notify employees whose credentials have been compromised, but avoid standard email channels for sensitive communications. Use secure internal messaging or access-controlled notifications when possible. - Review and audit account activity
For any impacted credentials, inspect recent login activity, changes in permissions, or access to sensitive data. Look for signs of lateral movement or unusual behavior. - Deactivate or re-evaluate unused accounts
If a compromised account is no longer active or necessary, shut it down entirely to eliminate risk.
Measure what matters: key metrics to track
To continuously improve your response to credential exposures, start tracking:
- Time to detect: How long did it take to spot the leak?
- Time to respond: How quickly was action taken after the alert?
- Number of exposed accounts per quarter: Are incidents increasing or decreasing over time?
- Repeat exposures: Are the same credentials showing up in multiple breaches? That may signal policy issues.
These KPIs help build accountability, justify investments in monitoring tools, and highlight areas of improvement.
Make review a routine
Set aside time for quarterly security reviews focused specifically on breach monitoring. Review previous alerts, assess the effectiveness of responses, and update your internal playbooks based on what you’ve learned.
Prey makes this process easier by delivering structured reports that can be stored, analyzed, and referenced during audits or internal reviews—helping you improve your response over time.
Additional tips to ensure an efficient dark web monitoring strategy
Monitor dark web forums
Dark web forums are online platforms where threat actors gather to discuss, trade, and sell compromised credentials, sensitive data, and other illicit goods and services. These forums are a major source of dark web threats, as they enable malicious users to gain access to organizations’ systems and data. Login credentials, security question answers, and other sensitive information are frequently exchanged on these sites, often leading to fraud, data theft, and business disruption.
For organizations, the risk is clear: compromised credentials found on dark web forums can be used to commit fraud, steal sensitive information, or launch further attacks. This makes it essential to use dark web monitoring tools that can scan these forums for exposed data related to your organization. By identifying compromised credentials and other sensitive data early, organizations can take proactive steps to secure accounts, notify affected users, and prevent further damage.
Monitoring dark web forums is a key part of any comprehensive web monitoring strategy, helping organizations stay alert to the latest threats and protect their most valuable assets from falling into the wrong hands.
Incorporate actionable intelligence via dark web data monitoring
Dark web data is a valuable resource for organizations looking to strengthen their cybersecurity defenses. By collecting and analyzing information from the dark web, security teams can gain deep insights into the tactics and targets of threat actors. This intelligence enables organizations to identify emerging threats, prioritize alerts, and implement proactive security measures to defend against dark web threats.
Dark web monitoring tools and services are designed to gather and contextualize dark web data, transforming raw information into actionable intelligence. This process helps organizations detect data leaks, protect sensitive company information, and prevent malicious actors from exploiting exposed data. By leveraging these insights, organizations can improve their overall security posture, respond more effectively to incidents, and reduce the risk of data breaches and other cyber threats.
Incorporating dark web monitoring into your security strategy ensures that your organization is not only aware of current threats, but also prepared to address new risks as they emerge. This proactive approach is essential for maintaining data privacy and safeguarding your organization’s most critical assets.
