What is data breach monitoring?
Data breach monitoring is the ongoing process of tracking external sources for leaked company-related data, including publicly disclosed data breaches, credential lists, and malware infection logs. This process helps security teams identify risks earlier and respond before the leaked data leads to account compromises, ransomware activity, or broader security incidents.
OVERVIEW
What data can be exposed in a data breach?
Login credentials
Usernames, passwords, password hashes, authentication tokens, security questions, and active session cookies.
Financial information
Payment card details, bank account numbers, transaction records, and billing information.
Personal Identifiable Information (PII)
Full names, home addresses, phone numbers, dates of birth, Social Security numbers, and government-issued ID details.
Employee data
Payroll records, tax-related information, internal communications, and other workforce-related data.
Corporate data
Client records, internal documents, intellectual property, business plans, and other sensitive company information.
Consumer data
Email addresses, usernames, passwords, and other account-related details tied to customers.
IN ACTION
How Data Breach Monitoring works
Data Breach Monitoring works by continuously scanning dark and deep web sources for an organization’s defined assets, such as emails and domains. When a match is found, the platform generates an alert and records the event to enable a swift response.
Intelligence collection
The solution gathers data from breach dumps, credential lists, infostealer logs, and other external sources in which compromised records appear.
Data enrichment
Each finding comes with supporting context, such as the source, timestamp, type of exposure, and affected data points.
Monitoring and alerting
New matches are continuously tracked, and your team is alerted when employee or consumer data is exposed.
Analysis and remediation
Exposed records are reviewed to identify who or what was affected, helping your team prioritize response and take corrective action faster.
BUILT FOR SECURITY TEAMS
Reduce exposure with proactive Data Breach Monitoring
Identify any leaked data tied to your business, and respond before exposed records lead to larger security incidents.
Protect employee accounts and consumer data
Compromised credentials can lead to fraud, account takeovers, and follow-on attacks. With NordLayer Intelligence by NordStellar, your team can detect exposed employee and consumer records across breach datasets, combolists, and malware logs, so you can investigate quickly and reduce risk sooner.
Lower the risk of ransomware
Leaked credentials and infected devices are often the initial access vectors behind most ransomware attacks. NordLayer Intelligence helps your team identify compromised systems and exposed access data early on, giving you a chance to contain threats before they disrupt operations.
Protect your executive team
Executives and other high-profile employees are common targets of phishing, impersonation, and account compromise. Monitor exposed credentials and leaked personal data tied to key personnel, and give your team earlier visibility into risks that may require immediate action.
Respond faster to infostealer-related exposure
Infostealer malware can extract passwords, session cookies, autofill data, and other sensitive information from infected devices. NordLayer Intelligence by NordStellar helps security teams detect these exposures, identify affected users, and take action before the stolen data is reused in later-stage attacks.
