Dark Web Monitoring for Businesses
Millions of professional credentials are circulating on the dark web. Some may belong to your organization.
The dark web is a hidden part of the internet where stolen data is traded and sold among cybercriminals. You’ll find there:
- corporate databases
- remote access credentials
- compromised Microsoft 365 accounts
- information that can be used to launch targeted attacks
A single compromised piece of information can be enough to trigger a cyberattack. The problem is that this data is often exploited before the affected organization even knows it has been exposed.
Your business may already be exposed without knowing it
Data breaches happen every day — whether through attacks, vendor breaches, or poor security practices. The information that ends up on the dark web can include:
- Professional email addresses belonging to your employees
- Passwords linked to those addresses
- Access to your Microsoft 365 environment
- Administrator accounts with elevated privileges
- Customer data or internal documents
- Strategic information about your organization
This information doesn't trigger any alerts in your systems. It circulates on forums and marketplaces you don't have access to. And it's often exploited quickly.
What we monitor for your organization
Rhesus’s dark web monitoring service continuously detects whether information linked to your domain is circulating on the dark web. We monitor:
- Professional accounts and email addresses associated with your domain
- Compromised passwords and credentials
- Exposed Microsoft 365 access
- Internal documents and data appearing in data leaks
- Mentions of your domain or organization
When an exposure is detected, you are alerted quickly so you can act on the affected accounts and passwords before they are exploited.
What happens when an exposure is detected
Unlike automated consumer tools that send an alert email with no follow-up, Rhesus offers a managed service. When an exposure is detected, here’s what happens:
- You receive an alert with the details of the exposure: which account, what type of data, which source
- Our team contacts you to assess the real risk and level of urgency
- Corrective actions are identified: password change, access revocation, MFA activation, activity log review
- If needed, our team can intervene directly to secure the compromised accounts
The difference between a tool and a managed service is what happens after the alert. A tool tells you there’s a problem. A managed service helps you fix it.
Why this matters for SMBs
Cyberattacks often start with already-compromised information. A single exposed password can be enough to access your emails, your shared files, or your internal systems.
SMBs are particularly vulnerable because:
- They often reuse the same passwords across multiple platforms
- Multi-factor authentication isn’t always enabled everywhere
- They don’t know their data is circulating on the dark web
- They don’t have the resources to monitor this themselves
With continuous monitoring, you detect leaks as they appear, reduce the risk of compromise, and take action before an incident occurs.
Warning signs: when to activate monitoring
Certain situations should prompt you to activate dark web monitoring immediately:
- You’ve already been the target of a phishing attempt or an intrusion
- Employees use their professional email to register for external services
- You have no visibility into data leaks that may involve your domain
- You use Microsoft 365 without active access monitoring
- A vendor or partner recently experienced a security breach
You can’t prevent every leak. But you can detect them quickly and act before they turn into an incident.

Frequently Asked Questions: Dark Web Monitoring
How do I know if my data is already on the dark web?
That’s precisely what monitoring is for. Rhesus continuously analyzes the dark web to detect whether information linked to your domain is circulating there. Without active monitoring, it’s practically impossible to know on your own.
What does Rhesus do when compromised credentials are detected?
You receive a detailed alert and our team guides you through securing the affected accounts: password changes, access revocation, MFA activation. If the situation is urgent, we can intervene directly. Call us at 1 844 758-2220.
Does dark web monitoring replace antivirus software?
No. They are two complementary protections. Antivirus protects your devices against malware. Dark web monitoring detects whether your credentials or data have been exposed outside your network.
How often is the dark web monitored?
Monitoring is continuous. The dark web is analyzed on an ongoing basis to detect new exposures linked to your domain.
What types of data circulate on the dark web?
Email addresses, passwords, access to cloud environments like Microsoft 365, customer databases, internal documents, and sometimes remote access to corporate networks.
How do credentials end up on the dark web?
Several scenarios: a security breach at an online service where an employee registered with their professional email, a successful phishing attack, malware that steals saved passwords, or a poorly protected database that was exfiltrated.
