What is a data breach scanner?

A data breach scanner is a tool or software designed to detect potential security vulnerabilities and data breaches within a computer network or system. These scanners continuously monitor various aspects of an organization's network, such as databases, servers, applications, and endpoints, to identify any unauthorized access, suspicious activities, or data leaks.

Protect Your Data with Scanning Solutions

Our data breach scanner employs advanced techniques to continuously monitor your network infrastructure, databases, and applications. With regular vulnerability assessments and behavioral analysis, we detect potential security breaches and vulnerabilities before they escalate. Our scanner also conducts thorough data discovery, ensuring sensitive information such as personally identifiable information (PII) and financial data is adequately protected. Real-time alerts and detailed reports empower you to respond promptly and mitigate the impact of security incidents.

Monitor Multiple Mails

Not only does our data breach scanner monitor emails within our mailing system or associated with our domain, but you can also include multiple emails from your own domain or Gmail.

Not only Data Comprises

Our scanners employ comprehensive techniques to proactively detect data that may be compromised, whether it's being sold online, shared on the dark web, or has surfaced in a breach.

Frequently asked questions

What is a "breach" and where has the data come from?

A "breach" is an incident where data is inadvertently exposed in a vulnerable system, usually due to insufficient access controls or security weaknesses in the software. HIBP aggregates breaches and enables people to assess where their personal data has been exposed.

Are user passwords stored in this site?

When email addresses from a data breach are loaded into the site, no corresponding passwords are loaded with them. Separately to the address search feature, Password service allows you to check if an individual password has previously been seen in a data breach. No password is stored next to any personally identifiable data (such as an email address) and every password is SHA-1 hashed.

What about breaches where passwords aren't leaked?

Occasionally, a breach will be added to the system which doesn't include credentials for an online service. This may occur when data about individuals is leaked and it may not include a username and password. However this data still has a privacy impact; it is data that those impacted would not reasonably expect to be publicly released and as such they have a vested interest in having the ability to be notified of this.

How is a breach verified as legitimate?

There are often "breaches" announced by attackers which in turn are exposed as hoaxes. There is a balance between making data searchable early and performing sufficient due diligence to establish the legitimacy of the breach. The following activities are usually performed in order to validate breach legitimacy:

  1. Has the impacted service publicly acknowledged the breach?
  2. Does the data in the breach turn up in a Google search (i.e. it's just copied from another source)?
  3. Is the structure of the data consistent with what you'd expect to see in a breach?
  4. Have the attackers provided sufficient evidence to demonstrate the attack vector?
  5. Do the attackers have a track record of either reliably releasing breaches or falsifying them?
