What is data breach monitoring?
Data breach monitoring is the process of continuously scanning the deep and dark web, as well as other sources, such as Telegram channels. It helps detect various types of exposed data, such as credentials, emails, credit card numbers, social security numbers, and other personally identifiable information (PII). A data breach check helps the company contain threats in a timely manner and prevent further damage.
How does data breach monitoring work?
Here’s how data breach monitoring works:
Data collection
Data is collected from various sources, such as the deep and dark web, Telegram channels, ransomware blogs, and threat actor communities.

Data enrichment
Relevant context, such as the breach source, date, and impacted data points, is added to enrich the collected data.
Monitoring and alerting
Continuous monitoring alerts the company when employee or consumer data is exposed.

Analysis and remediation
Leaked data is analysed to identify affected employees and consumers, and respond appropriately.
Detect data breaches before cybercriminals harm your business
A single leaked password can lead to serious issues for a company. You can face serious cyber incidents, exposed consumer data, and significant financial losses due to reputational damage and regulatory fines. But you can prevent the damage with NordStellar’s data breach monitoring.

What information can be exposed in a data breach?
A data leak can expose various types of sensitive information:
Personal Identifiable Information (PII)
Full name, home address, phone number, date of birth, Social Security number, and government-issued IDs.
Financial information
Credit card details, bank account numbers, transaction history, and billing addresses.

FAQ
A data breach is any security incident in which an unauthorized party gains access to private, sensitive, or confidential information. Types of data breaches include credential leaks, financial data theft, and personal information exposure.
A data breach is a very serious security issue often leading to legal penalties, loss of consumer trust, and financial damage. Without a data leak monitoring system, assessing the true scope of the damage can be difficult.
Data breaches can happen for many reasons. For example, weak credentials can be easily guessed or given away during a phishing attack. A phishing attack can also expose sensitive data. Some other reasons include malware, unpatched software vulnerabilities, human error and third-party vendor vulnerabilities, and misconfigured security settings.
Recovering from any cyber incident, such as a data breach, depends on its severity. According to IBM, it often takes around 204 days to identify a data breach and an additional 73 days to contain it. In cases where credentials were stolen, the timeline often extends further.
If your company experiences a data breach, acting fast and containing the breach must be your priority. This means isolating affected systems, disabling compromised accounts, and restricting unauthorized access. Then, you’ll need to assess the situation and take steps to prevent it in the future:
- Assess the damage.
- Notify relevant stakeholders.
- Investigate and document the breach.
- Strengthen security measures.
- Report to authorities.
- Use data leak monitoring to continuously check for data breaches.
