Run a breach check to see whether a domain or service has been involved in known data breaches. Review breach incidents, exposed data types, and affected account counts.
A data breach check queries known breach databases and incident reporting platforms to determine whether a domain or service has been involved in publicly reported data breaches. Data breaches occur when unauthorized parties gain access to systems containing personal information, credentials, financial data, or other sensitive records. These incidents are often publicly disclosed, reported to regulators, or added to breach notification databases like Have I Been Pwned, breach monitoring services, and security research platforms. Our breach checker aggregates data from multiple breach databases to provide a comprehensive view of a domain's exposure history, including the number of incidents, dates, exposed data types, and affected account counts.
Knowing that a service you use has been breached allows you to take immediate protective action: change passwords, enable multi-factor authentication, monitor for suspicious activity, and check whether your personal data was exposed. For organizations, breach history affects vendor risk assessments and compliance obligations.
Reusing passwords across services, not changing passwords after a breach notification, not enabling multi-factor authentication, not monitoring for new breach disclosures, and assuming old breaches don't matter because you changed passwords once.
Type the domain or service to check for known breaches.
We query multiple breach databases and incident reporting platforms.
We compile breach incidents, dates, and exposed data types.
We present breach history with affected account counts and recommendations.
Queries multiple breach databases and incident reporting platforms including Have I Been Pwned, breach monitoring services, and security research platforms. Searches for the domain in known breach disclosures and public incident reports.
For each detected breach, reports the breach name, discovery date, occurrence date, description, exposed data types (passwords, emails, credit cards, etc.), and the number of affected accounts or records.
Aggregates total exposure counts across all detected breaches for the domain. Shows the cumulative number of accounts, records, or users that may have been affected by breaches associated with the domain.
Identifies which types of data were exposed in each breach incident. Common data types include passwords, email addresses, names, phone numbers, physical addresses, credit card numbers, and security questions.
Provides specific recommendations based on detected breaches. This includes changing passwords, enabling multi-factor authentication, monitoring for identity theft, using password managers, and checking for credential stuffing attacks.
Presents breach incidents in chronological order to show the domain's exposure history over time. Helps identify whether the domain has recurring security issues or a single historical incident.
Automate breach checks for your entire domain portfolio, get alerted when new breach incidents are reported, monitor vendor security posture, and integrate breach intelligence into your security workflows.
