Data breach monitoring for your domains and employees
Watch your company domains and email addresses, get alerted when new exposed data matches them, and see exactly which accounts are affected.
Create a free account to start investigating.
Investigate the exposed records, with the data to act.
File lines, not a count of unique accounts.
UpdatedPlaintext passwords, with their account context
Inspect the exposed password alongside the account and, for stealer logs, its service URL. When the source includes plaintext, that detail helps your team scope password resets and investigate exposed access.
Compare plans for plaintext access and included unlock points.
Stealer logs
Connect a captured login to its service URL, username and password to understand which access is exposed.
url:user:passCombolists
Find email/password and username/password pairs, including records without a service URL.
email:passuser:passRaw leak files
Search the text of leaked files, database dumps and unstructured records beyond normalized credential fields.
Dark web forums
Search indexed forum posts for mentions of your organization and examine the discussion's source context.
Get notified via Email, Slack, Discord, Telegram or Webhook when new exposed credentials match your monitored domains or email addresses.
A breach notice tells you that something leaked, not what.
Most breach alerts name an incident and stop there. To respond, your team needs the record: which account, on which service, with which data. Data breach monitoring in LeakRadar starts from your domain and takes you to the matching records, so the alert is the beginning of the investigation.
An alert is useful when it leads to the affected account.
From a breach alert to the affected accounts
- 01
Monitor your domains and addresses
Sign in and add the company domains and email addresses you are authorized to monitor.
- 02
Receive the alert
Get notified via Email, Slack, Discord, Telegram or Webhook when new exposed credentials match your monitored domains or email addresses.
- 03
Review what was exposed
Open the matching records, check the account and the service, then export the findings or share the domain report with your team.
Data breach monitoring, in practice
What is data breach monitoring?
It is the ongoing check of leaked and stolen data for information tied to your organization: company domains, employee email addresses, customer accounts. It turns a one-time breach check into a routine.
Breach check or breach monitoring?
A breach check answers a question once: does this address or domain appear today? Monitoring keeps asking and alerts you when the answer changes. Teams usually start with a check on their domain, then monitor it.
Why monitor a domain and not only email addresses?
A domain search covers every address of the organization, including accounts nobody thought to list, and separates employees, third parties and customers. Address monitoring fits a short list of sensitive accounts.
What to do after a data breach alert?
Confirm that the accounts are in your scope, reset the affected credentials, revoke relevant sessions and review access logs. Keep a record of what was found and when, for your incident process.
What you can work with
Access that fits your work
Start with a free account, then choose the plan that fits your datasets, monitoring, exports and team.
Compare plansSeveral kinds of sources
Stealer logs, combolists, raw leak files and dark web forum posts, according to your plan.
Record-level context
Each match shows the account and, for stealer logs, the service URL. Credentials stay masked until you unlock them.
A report to share
Use the domain PDF report or available exports to bring findings into your team's review.
Before you get started
Does data breach monitoring cover the dark web?
LeakRadar searches dark web forum posts as a separate dataset, according to your plan. Monitoring alerts are about new exposed credentials that match your domains or email addresses.
How do alerts arrive?
By Email, Slack, Discord, Telegram or webhook. The channels and the number of monitored assets depend on your plan.
Can we monitor several company domains?
Yes, within your plan's monitoring capacity. Configure the domains in your member account and choose the relevant alert channels.
Is there a free data breach monitoring option?
The free account can monitor its signup email in Stealer Logs, with notifications sent to that address. Additional assets, datasets and notification channels depend on a paid plan.
Does a result mean our servers were breached?
No. A credential associated with your domain may come from a compromised device or another service. Examine its context before drawing conclusions.
Can I export what was found?
Yes. Large exports run as background jobs in CSV, TXT or JSON, and a domain report is available as a PDF. Available exports depend on your plan.
