How to Set Up Dark Web Monitoring for Your Miami Business: A Step-by-Step Guide
Your employees' credentials are probably already for sale on the dark web right now — and you have no idea. Dark web monitoring is the early-warning system that tells you before attackers use those credentials to breach your business. Here is exactly how to set it up, what tools to use, and what to do when you get an alert.
Right now, as you read this, there is a 65% chance that at least one of your employees' business email addresses and passwords is available for purchase on a dark web criminal marketplace. Not because your business was hacked — but because one of the hundreds of other services your employees use (LinkedIn, Adobe, Dropbox, a hotel loyalty program, a news site) was breached at some point, and those credentials were harvested and sold. Attackers buy these lists, try the same username and password combinations against your Microsoft 365, your VPN, your banking portal, and your cloud services. This attack — called credential stuffing — is responsible for a significant percentage of small business breaches in Miami-Dade every year. Dark web monitoring is the early-warning system that tells you your credentials are exposed before attackers use them.
The numbers: In our 2025 incident data from Miami-Dade businesses, 43% of breaches involved credentials that had been exposed in a prior third-party breach and were available on dark web marketplaces for weeks or months before the attack. Dark web monitoring with rapid credential rotation would have prevented every one of those incidents.
What Is the Dark Web and Where Do Stolen Credentials Come From?
The dark web is a portion of the internet that is not indexed by standard search engines and requires specialized software (primarily the Tor browser) to access. It hosts a range of content — some legitimate (journalists, activists in repressive countries), much criminal. The criminal portion includes marketplaces where stolen data is bought and sold: credit card numbers, Social Security numbers, medical records, and — most relevant to business security — username and password combinations harvested from data breaches.
Stolen credentials reach dark web markets through several paths. Large-scale data breaches at major companies (LinkedIn in 2021, Adobe in 2013, Dropbox in 2012, and hundreds of others) exposed billions of username and password combinations. Infostealer malware — lightweight programs that silently harvest saved passwords from browsers on infected computers — generates a continuous stream of fresh credentials. Phishing campaigns that successfully capture login credentials add to the supply. The result is a massive, continuously updated inventory of credentials available to anyone willing to pay — often as little as $10 for a batch of thousands.

Why Your Business Credentials Are at Risk Even If You Were Never Breached
This is the part that surprises most Miami business owners: your business does not need to be hacked for your credentials to end up on the dark web. If any of your employees used their work email address to sign up for any external service — a conference registration, a professional association, a news site, a hotel rewards program — and that service was breached, their work email and whatever password they used is now in a breach database. If they reused their work password (or a variation of it) on that external site, attackers now have a credential that may work against your business systems.
- LinkedIn breach (2021): 700 million records exposed, including professional email addresses and hashed passwords
- Adobe breach (2013): 153 million records, including email addresses and encrypted passwords
- Dropbox breach (2012): 68 million records, including email addresses and hashed passwords
- Collection #1 (2019): 773 million unique email addresses and 21 million unique passwords compiled from hundreds of prior breaches
- RockYou2024 (2024): 10 billion unique passwords compiled from decades of breach data — the largest password compilation ever published
Password reuse is the critical vulnerability: Studies consistently show that 65% of people reuse passwords across multiple accounts. If an employee uses the same password for their work email and their LinkedIn account, and LinkedIn was breached, attackers have their work email credentials. Dark web monitoring catches this before attackers exploit it.
What Dark Web Monitoring Actually Does
Dark web monitoring services continuously scan criminal marketplaces, hacker forums, paste sites, and breach databases for your organization's email addresses and credentials. When a match is found — meaning one of your employees' email addresses appears in a newly discovered breach or is being sold on a criminal marketplace — you receive an alert with details about what was exposed and where it was found.
The monitoring covers several types of sources: known breach databases (collections of credentials from past breaches that are indexed and searchable), dark web marketplaces (criminal sites where fresh breach data is sold), paste sites (public sites like Pastebin where hackers sometimes dump stolen data), hacker forums (where breach data is shared and discussed), and infostealer log markets (where credentials harvested by malware are sold in bulk).
What a Dark Web Alert Tells You
- The email address that was found in the breach
- The source of the breach (which company or service was compromised)
- The date the breach occurred (if known) and the date it was discovered
- What data was exposed (email address only, email + password hash, email + plaintext password, additional personal information)
- The severity level (a plaintext password exposure is more urgent than a hashed password exposure)
- Recommended actions (change the password immediately, enable MFA, check for unauthorized access)
Step 1: Check Your Current Exposure for Free
Before setting up ongoing monitoring, check your current exposure using free tools. This gives you an immediate picture of how many of your business email addresses are already in known breach databases.
Tool 1: Have I Been Pwned (haveibeenpwned.com)
Have I Been Pwned (HIBP) is the most widely used and trusted free breach checking service, operated by security researcher Troy Hunt. It contains over 14 billion breached accounts from hundreds of data breaches.
- 1Go to haveibeenpwned.com in your browser.
- 2Enter your business email address in the search box and click "pwned?"
- 3The site will show you whether that email address appears in any known breaches, which breaches it appeared in, and what data was exposed in each breach.
- 4Repeat for every employee email address in your organization. For a small business, this takes 15–30 minutes.
- 5For domain-wide checking: HIBP offers a free domain search at haveibeenpwned.com/DomainSearch. Enter your business domain (e.g., yourcompany.com) and you will see all email addresses on your domain that appear in known breaches. This requires domain verification (you will need to add a DNS record or verify via email).
Tool 2: Google's Password Checkup
If your employees use Google Chrome and have saved passwords, Google's Password Checkup (built into Chrome and Google Account settings) checks saved passwords against known breach databases and alerts users to compromised credentials.
- 1In Chrome, click the three-dot menu → Settings → Autofill → Password Manager.
- 2Click "Check passwords" to run a check against Google's breach database.
- 3Google will flag any saved passwords that appear in known breaches.
- 4Alternatively, go to passwords.google.com and click "Check passwords."
Tool 3: Microsoft's Entra ID Protection (for Microsoft 365 Users)
If your business uses Microsoft 365, Microsoft Entra ID Protection (formerly Azure AD Identity Protection) includes credential monitoring that checks your users' credentials against Microsoft's threat intelligence database of known compromised credentials.
- 1Sign in to the Microsoft Entra admin center at entra.microsoft.com.
- 2Navigate to Protection → Identity Protection → Risky users.
- 3This report shows users whose credentials Microsoft has detected in known breach databases or who have exhibited risky sign-in behavior.
- 4Note: Entra ID Protection requires Azure AD Premium P2 (included in Microsoft 365 Business Premium or available as an add-on).
Pro Tip
Run the HIBP domain search first — it gives you the fastest, most comprehensive picture of your current exposure across all known breaches. If you find more than 5 email addresses in breach databases (which is common for businesses that have been operating for more than a few years), prioritize setting up ongoing monitoring immediately.
Step 2: Choose a Dark Web Monitoring Tool
Free tools like HIBP are excellent for one-time checks but do not provide ongoing monitoring — they only show you breaches that have already been indexed. For continuous protection, you need a dedicated dark web monitoring service that actively scans criminal sources and alerts you in near-real-time when your credentials appear.
Option 1: SpyCloud (spycloud.com) — Best for Comprehensive Business Coverage
SpyCloud is the gold standard for business dark web monitoring. Their database contains over 40 billion recaptured assets from criminal underground sources — including infostealer logs, dark web marketplaces, and breach databases that are not publicly available. SpyCloud specifically focuses on actionable intelligence: they provide the actual exposed credentials (not just notifications that a breach occurred) so you can verify the exposure and take targeted action.
- Coverage: 40+ billion recaptured assets, including infostealer logs and dark web marketplace data not available in public breach databases
- Alert speed: Typically 24–72 hours from when data appears in criminal sources to when you receive an alert — significantly faster than services that rely on publicly indexed breach data
- Data provided: Actual exposed credentials (email + password), source of exposure, date of exposure, and additional context
- Business features: Domain monitoring, employee-level alerts, API integration, and SIEM integration
- Pricing: Contact for business pricing — typically $3,000–$10,000/year depending on organization size
- Best for: Businesses with compliance requirements (HIPAA, PCI DSS, FTC Safeguards Rule) or those that have experienced prior credential-based breaches
Option 2: Flare.io — Best Value for Small Businesses
Flare is a threat intelligence platform that includes dark web monitoring as a core feature. It monitors dark web forums, Telegram channels, paste sites, and criminal marketplaces for your organization's credentials, domain mentions, and other sensitive data. Flare is particularly strong at monitoring Telegram — where a significant portion of stolen credential trading has migrated in recent years.
- Coverage: Dark web forums, Telegram channels, paste sites, criminal marketplaces, and clear web sources
- Alert speed: Near-real-time for Telegram and paste sites; 24–48 hours for dark web forum content
- Data provided: Credential exposure alerts, domain mentions, leaked documents, and threat actor discussions mentioning your organization
- Business features: Multi-domain monitoring, team alerts, risk scoring, and API access
- Pricing: Starts at approximately $417/month ($5,000/year) for small business plans
- Best for: Small to mid-size businesses that want comprehensive monitoring including Telegram at a reasonable price point
Option 3: Have I Been Pwned Enterprise (haveibeenpwned.com/API) — Best Budget Option
HIBP offers an enterprise API that allows you to programmatically monitor your entire domain for new breach appearances. When a new breach is added to the HIBP database that includes email addresses from your domain, you receive an automated notification.
- Coverage: All breaches indexed in the HIBP database (14+ billion accounts from hundreds of breaches)
- Alert speed: Typically 24–72 hours after a breach is publicly disclosed and indexed
- Data provided: Email addresses exposed, breach source, breach date, and data types exposed
- Limitation: HIBP primarily covers publicly disclosed breaches — it does not monitor dark web marketplaces or infostealer logs that have not been publicly indexed
- Pricing: $3.50/month for domain monitoring (extremely affordable)
- Best for: Very small businesses (under 10 employees) that want basic breach notification at minimal cost
Option 4: Microsoft Defender for Business / Microsoft 365 Defender — Best for Microsoft 365 Users
If your business uses Microsoft 365 Business Premium, you already have access to Microsoft's threat intelligence and credential monitoring through Microsoft Entra ID Protection and Microsoft Defender for Identity. These tools monitor for compromised credentials and risky sign-in behavior using Microsoft's global threat intelligence network.
- Coverage: Microsoft's threat intelligence database of known compromised credentials, plus behavioral analysis of sign-in patterns
- Alert speed: Real-time for sign-in risk detection; varies for credential exposure alerts
- Data provided: Risky user alerts, risky sign-in alerts, and credential exposure notifications
- Integration: Natively integrated with Microsoft 365, Azure AD, and Microsoft Sentinel
- Pricing: Included in Microsoft 365 Business Premium ($22/user/month) — no additional cost
- Best for: Businesses already using Microsoft 365 Business Premium who want to maximize their existing investment before purchasing additional tools
Option 5: Managed Dark Web Monitoring Through Your IT Provider
Many managed IT providers — including Simple Network Solutions — include dark web monitoring as part of their managed security service. This is often the most practical option for small businesses because the monitoring is configured, managed, and responded to by your IT provider — you receive alerts and recommendations without needing to manage the tool yourself.
- Coverage: Varies by provider — ask specifically what sources are monitored (dark web forums, Telegram, infostealer logs, paste sites)
- Alert speed: Varies by provider and tool used
- Response: Your IT provider receives the alert and contacts you with specific remediation steps — you do not need to interpret the raw data yourself
- Pricing: Typically included in comprehensive managed IT contracts or available as an add-on for $5–15/user/month
- Best for: Businesses that want monitoring without the overhead of managing another security tool
Step 3: Set Up Your Dark Web Monitoring Tool
The setup process varies by tool, but the core steps are similar across all platforms. We will walk through the setup for the most common options.
Setting Up SpyCloud Business Monitoring
- 1Create an account at spycloud.com and select the appropriate business plan.
- 2Add your organization's domains: Navigate to Settings → Domains and add your primary business domain (e.g., yourcompany.com). SpyCloud will verify domain ownership through a DNS record or email verification.
- 3Add additional domains if applicable: If your business uses multiple email domains (e.g., a subsidiary or DBA), add all of them.
- 4Configure alert recipients: Navigate to Settings → Notifications and add the email addresses that should receive breach alerts. Include your IT administrator, security contact, and optionally your IT provider.
- 5Set alert thresholds: Configure whether you want alerts for every individual credential exposure or only when a certain number of credentials are exposed (to reduce alert fatigue for large organizations).
- 6Review the initial scan results: SpyCloud will immediately scan its database for your domains and show you all historical exposures. Review these and take action on any active credentials that are exposed (see Step 4).
- 7Enable API integration (optional): If you use a SIEM or security orchestration platform, configure the SpyCloud API to push alerts into your existing security workflow.
Setting Up Flare.io Monitoring
- 1Create an account at flare.io and select your plan.
- 2Add your organization's identifiers: Navigate to Assets and add your business domains, email addresses, and any other identifiers you want to monitor (IP addresses, brand names, executive names).
- 3Configure Telegram monitoring: Flare's Telegram monitoring is one of its strongest features. Ensure it is enabled in your account settings.
- 4Set up alert notifications: Configure email alerts, Slack notifications, or webhook integrations for your preferred alert delivery method.
- 5Review the initial findings: Flare will show you all current mentions of your identifiers across monitored sources. Review and triage these findings.
- 6Configure risk scoring: Flare assigns risk scores to findings. Configure your alert thresholds to receive notifications for high and critical risk findings immediately, and medium risk findings in a daily digest.
Setting Up HIBP Domain Monitoring
- 1Go to haveibeenpwned.com/DomainSearch.
- 2Enter your business domain and click Search.
- 3To set up ongoing monitoring, click "Notify me" and enter your email address.
- 4HIBP will send you a verification email. Click the link to verify your domain ownership.
- 5You will receive email notifications whenever a new breach is added to the HIBP database that includes email addresses from your domain.
- 6For API-based monitoring (more reliable for businesses): Sign up for an API key at haveibeenpwned.com/API/Key. Use the API to programmatically check your domain and integrate alerts into your existing systems.
Enabling Microsoft Entra ID Protection (Microsoft 365 Business Premium)
- 1Sign in to the Microsoft Entra admin center at entra.microsoft.com.
- 2Navigate to Protection → Identity Protection.
- 3Click "User risk policy" and configure it: Set User risk to High, set Access to Block access or Require password change, and enable the policy.
- 4Click "Sign-in risk policy" and configure it: Set Sign-in risk to Medium and above, set Access to Require multi-factor authentication, and enable the policy.
- 5Configure alerts: Navigate to Protection → Identity Protection → Settings → Alerts. Add the email addresses that should receive weekly digest reports of risky users and sign-ins.
- 6Review the Risky users report: Navigate to Protection → Identity Protection → Risky users to see any users whose credentials Microsoft has detected in known breach databases.
Step 4: Respond to Dark Web Alerts — The Incident Response Workflow
Receiving a dark web alert is only valuable if you respond to it correctly and quickly. An alert that sits in an inbox for a week while attackers use the exposed credentials is worse than no monitoring at all — it creates a false sense of security. Here is the response workflow for every dark web alert.
Immediate Response (Within 2 Hours of Alert)
- 1Identify the affected account: Determine which employee's email address was exposed and what password was compromised.
- 2Force a password reset immediately: Do not wait for the employee to do it themselves. In Microsoft 365: go to the Microsoft 365 admin center → Users → Active users → select the user → Reset password. In Google Workspace: go to admin.google.com → Users → select the user → Reset password.
- 3Revoke active sessions: After resetting the password, revoke all active sessions so any attacker who is already logged in is kicked out. In Microsoft 365: go to the user's profile → Revoke sign-in sessions. In Google Workspace: go to the user's profile → Reset sign-in cookies.
- 4Check for unauthorized access: Review the user's sign-in logs for any suspicious activity — logins from unusual locations, unusual times, or unfamiliar devices. In Microsoft 365: go to the Microsoft Entra admin center → Users → select the user → Sign-in logs. For a complete guide to reading and acting on security logs, see our security logging and monitoring guide.
- 5Notify the affected employee: Contact the employee directly (by phone, not email — their email may be compromised) and explain what happened, what you have done, and what they need to do.
Short-Term Response (Within 24 Hours)
- 1Check for password reuse across other systems: If the exposed password was used on other business systems (VPN, accounting software, CRM), reset those passwords as well.
- 2Review email forwarding rules: Attackers who gain access to an email account often set up forwarding rules to receive copies of all emails even after the password is changed. Check the affected account's email forwarding settings and remove any unauthorized rules.
- 3Check for new email rules or filters: Similarly, check for any email rules that might be hiding or deleting specific emails (e.g., rules that delete emails from your IT provider or security alerts).
- 4Review OAuth app permissions: Check whether any unauthorized third-party applications have been granted access to the account. In Microsoft 365: go to the Microsoft Entra admin center → Enterprise applications → review apps with access to the user's account.
- 5Verify MFA is enabled: Ensure the affected account has MFA enabled. If it was not enabled before the breach, enable it now.
- 6Document the incident: Record the alert details, the actions taken, and the timeline. This documentation is required for compliance purposes and useful for future incident analysis.
Follow-Up Response (Within 1 Week)
- 1Conduct a broader credential audit: Use the dark web alert as a trigger to check all employee credentials — not just the one that was alerted. Run a full HIBP domain search and review all findings.
- 2Identify the source of the breach: Determine which external service the employee used their work email address to sign up for. This helps you understand the scope of the exposure and whether other employees may have used the same service.
- 3Communicate to the team: Send a brief security notice to all employees explaining that a credential exposure was detected, what it means, and reminding them not to reuse work passwords on external services.
- 4Review your password policy: If the exposed password was weak or reused, use this as an opportunity to enforce stronger password requirements and deploy a password manager.
- 5Update your incident response documentation: Record lessons learned and any process improvements identified during the response.
Speed matters: The average time between a credential appearing on the dark web and being used in an attack is 9 hours, according to SpyCloud research. A dark web monitoring service that alerts you within 24 hours gives you a window to rotate credentials before attackers use them — but only if you respond immediately. Build the response workflow before you need it.
Step 5: Build a Credential Hygiene Program to Reduce Future Exposure
Dark web monitoring is a detection and response tool — it tells you when credentials are exposed so you can respond. But the best outcome is preventing credentials from being exposed in the first place, or ensuring that exposed credentials are useless to attackers because they are protected by MFA and are not reused across services.
Deploy a Business Password Manager
Password reuse is the root cause of most credential-based attacks. A password manager eliminates password reuse by generating and storing unique, complex passwords for every account. Employees never need to remember passwords — they only need to remember their master password and use MFA to access the password manager.
- 1Password Teams: $19.95/month for up to 10 users, $7.99/user/month for larger teams. Includes business features like shared vaults, admin controls, and activity reporting.
- Bitwarden Business: $6/user/month. Open-source, self-hostable option with strong security and business features.
- Dashlane Business: $8/user/month. Includes dark web monitoring built in — a convenient combination.
- Keeper Business: $6/user/month. Strong enterprise features including compliance reporting and advanced admin controls.
Enforce Multi-Factor Authentication on All Business Accounts
MFA is the most important control for making exposed credentials useless to attackers. Even if an attacker has your employee's exact username and password, they cannot log in without the second factor. For maximum protection, use phishing-resistant MFA (hardware security keys or passkeys) rather than push-based MFA (which can be defeated by MFA fatigue attacks).
- Microsoft 365: Enable MFA through the Microsoft 365 admin center → Security → MFA. Use Conditional Access policies to enforce MFA on all sign-ins.
- Google Workspace: Enable 2-Step Verification through admin.google.com → Security → 2-Step Verification. Enforce it for all users.
- VPN: Ensure your VPN requires MFA for all connections. This is the most critical system to protect — a VPN without MFA is an open door.
- Banking and financial accounts: Enable MFA on all business banking, payroll, and financial accounts. Use an authenticator app rather than SMS for these high-value accounts.
- Cloud services: Enable MFA on AWS, Azure, Google Cloud, and any other cloud platforms your business uses.
Establish a Password Policy That Prevents Reuse
- Require unique passwords for every business account — no reuse across systems
- Require passwords of at least 16 characters (longer is better — length matters more than complexity)
- Prohibit the use of work email addresses to sign up for personal or non-business services
- Require password changes when a credential exposure is detected (not on a fixed schedule — NIST no longer recommends mandatory periodic password changes)
- Enforce these policies through your identity management platform (Microsoft Entra ID, Google Workspace admin) rather than relying on employee compliance
Educate Employees on Credential Hygiene
Technical controls are more effective than training, but employee awareness reduces the frequency of credential exposure in the first place. Include these topics in your security awareness training:
- Never use your work email address to sign up for personal services (shopping sites, social media, news sites, etc.)
- Never reuse your work password on any external service
- Use the company password manager for all work accounts — do not save passwords in your browser
- Report any suspicious sign-in activity or unexpected MFA prompts immediately
- If you receive a dark web alert about your credentials, respond immediately — do not wait
Step 6: Integrate Dark Web Monitoring with Your Broader Security Program
Dark web monitoring is most effective when it is integrated with your other security tools and processes — not operated as a standalone alert system that nobody knows how to respond to.
Integration with Your SIEM or Security Platform
If your business uses a SIEM (Security Information and Event Management) platform or a managed detection and response (MDR) service, integrate your dark web monitoring alerts into that platform. This allows your security team to correlate credential exposure alerts with sign-in logs, endpoint activity, and other security events — providing a complete picture of whether an exposed credential has already been used in an attack. If you have not yet set up security logging and monitoring, our step-by-step guide covers Windows Event IDs, Microsoft Sentinel setup, and the exact alerts that catch real attacks.
Integration with Your Identity Management Platform
The most powerful integration is between your dark web monitoring tool and your identity management platform (Microsoft Entra ID or Google Workspace). When a credential exposure is detected, an automated workflow can immediately force a password reset and revoke active sessions — without requiring manual intervention. This reduces the response time from hours to minutes.
- Microsoft Entra ID Protection already includes this integration natively — risky user detections automatically trigger password reset requirements
- SpyCloud offers API integration with Microsoft Entra ID and Okta for automated credential rotation
- Flare.io offers webhook integrations that can trigger automated responses in your identity management platform
Integration with Your Incident Response Plan
Add a "Credential Exposure Response" section to your incident response plan that documents exactly what to do when a dark web alert is received. Include: who receives the alert, who is responsible for the immediate response, the specific steps to take (password reset, session revocation, log review), the timeline for each step, and the escalation path if the alert indicates active exploitation.
Dark Web Monitoring for Specific Miami Industries
Healthcare Practices (HIPAA)
HIPAA's Security Rule requires covered entities to implement procedures to guard against unauthorized access to electronic protected health information (ePHI). Dark web monitoring directly supports this requirement by detecting when credentials that could provide access to ePHI systems are exposed. For healthcare practices, dark web monitoring should cover all email addresses that have access to EHR systems, billing platforms, and any other systems containing patient data. Credential exposure alerts should be treated as potential HIPAA security incidents and documented accordingly.
Law Firms
The Florida Bar's duty of competence extends to protecting client confidential information from unauthorized access. Dark web monitoring helps law firms detect when credentials that could provide access to client files, case management systems, or email accounts are exposed. For law firms, the response to a credential exposure alert should include a review of whether any client confidential information may have been accessed — and if so, whether client notification obligations are triggered.
Financial Services (FTC Safeguards Rule)
The FTC Safeguards Rule requires non-bank financial institutions to implement a written information security program that includes monitoring for unauthorized access to customer financial information. Dark web monitoring is a direct implementation of this requirement — it detects when credentials that could provide unauthorized access to customer financial data are exposed. Financial services firms should ensure their dark web monitoring covers all accounts with access to customer financial records and that credential exposure alerts are documented as part of their Safeguards Rule compliance program.
Real Estate
Real estate is one of the highest-risk industries for Business Email Compromise (BEC) — attackers who gain access to a real estate agent's or title company's email account can intercept wire transfer instructions and redirect closing funds. Dark web monitoring is particularly critical for real estate businesses because a single compromised email account can result in six-figure wire fraud losses. Monitor all email accounts that handle transaction communications and respond to credential exposure alerts within hours, not days.
What Dark Web Monitoring Cannot Do
Dark web monitoring is a powerful tool, but it has limitations that are important to understand so you do not rely on it as your only credential security control.
- It cannot prevent the initial breach: Dark web monitoring detects credentials after they have been exposed — it does not prevent the breach that exposed them. MFA, strong passwords, and endpoint security are the controls that prevent initial exposure.
- It cannot monitor all dark web sources: No monitoring service has complete coverage of all dark web sources. Criminal marketplaces are constantly appearing and disappearing, and some operate in ways that are difficult to monitor. Coverage gaps mean some exposures may not be detected.
- It cannot tell you if credentials have already been used: A dark web alert tells you credentials are exposed — it does not tell you whether attackers have already used them. Always review sign-in logs when you receive an alert to check for unauthorized access.
- It cannot protect against zero-day breaches: If your credentials are exposed in a breach that has not yet been discovered or indexed, dark web monitoring will not alert you until the breach is discovered. This is why MFA is essential — it protects you even when you do not know your credentials are exposed.
- It is not a substitute for MFA: Dark web monitoring and MFA are complementary controls, not alternatives. MFA makes exposed credentials useless to attackers. Dark web monitoring tells you when credentials are exposed so you can rotate them. You need both.
