Check whether your email address has appeared in any publicly-disclosed data breach, paste site, or credential dump. Powered by aggregated breach intelligence (XposedOrNot). Free, instant, no signup.
The scanner sends your email to the XposedOrNot API, which queries an aggregated database of publicly-disclosed breaches. If your email appears in any indexed breach, the scanner returns the list of breaches and details about each one. The same backend powers our Email Breach Checker — same data source, different framing for different search intent.
Honest scope: what we actually check. Despite the "dark web" branding, this scanner does not crawl Tor sites, hidden marketplaces, or pays-for-access cybercrime forums. It checks the corpus of publicly-disclosed breaches that breach aggregators have indexed — LinkedIn 2012, Adobe 2013, MyFitnessPal 2018, Capital One 2019, and the hundreds of others that have been publicly disclosed and ended up in aggregated databases. That corpus overlaps heavily with what attackers actually use for credential stuffing, so the practical security signal is the same. But the term "dark web monitoring" is essentially an industry-standard marketing label for breach-database monitoring; actual dark-web crawling is what enterprise threat-intelligence vendors do (Recorded Future, Flashpoint, DigitalShadows).
What gets returned. For each breach your email appears in, the scanner shows the breach name, the year it occurred, what types of data were exposed (passwords, names, addresses, phone numbers, etc.), and the breach description. Multiple breaches usually mean your email has been "out there" for years — common for any email older than a few years given the volume of breaches across the 2010s and 2020s.
Privacy of the lookup itself. Your email is sent to the XposedOrNot API over HTTPS. XposedOrNot states they do not log queries; the disclaimer below the scanner repeats this. SecurityElites does not store your email — the input never touches our servers, the request goes browser-direct to the third-party API. For paranoid use, consider running breach checks via downloaded breach corpus locally (HaveIBeenPwned offers a downloadable hash database) instead of any third-party scanner.
What this scanner does NOT do. It does not check passwords (use the Password Breach Checker for that — it uses HIBP\'s k-anonymity protocol so the actual password never leaves your browser). It does not provide ongoing alerts when new breaches appear (that requires a paid monitoring service or your own scripted re-checks). It does not check whether your email is being actively traded on cybercrime forums right now (that requires actual dark-web monitoring at the enterprise-vendor level). It is a one-shot exposure check against the publicly-disclosed corpus, not a continuous monitoring service.
Run the scan against each of your active email addresses every quarter. New breaches get indexed continuously, so a clean scan three months ago may show new entries today. The action when something new appears is always the same — change the affected service\'s password and any reused passwords. Quarterly cadence catches new exposures while they are still actionable.
Send the scanner link to family members or friends who do not work in security. Seeing concrete breach exposure for their own email is more motivating than abstract advice about password security. Particularly valuable for older relatives — they often have decade-old emails that appear in dozens of breaches, which makes the password-manager and MFA case immediately concrete rather than theoretical.
For non-security teams getting their first onboarding (engineering hires, marketing hires, finance hires), running this scan against their work email puts the credential-stuffing threat in personal terms. "Here are the breaches your email is in; here\'s why we mandate MFA + password manager + no password reuse" is a much more compelling onboarding moment than reading the security policy alone.
Major breach hits the news (LastPass, Okta, Twilio, MOVEit, etc.). Run the scanner against your email — does the new breach show up yet, and what other breaches has your email appeared in? Both signals are useful. The new breach tells you whether the affected service\'s data is in the publicly-leaked corpus; existing entries remind you which other passwords need attention if you reused.
For vendor risk assessment, check whether the vendor\'s primary contact emails appear in breaches. Most do (everyone\'s email appears in breaches eventually) but a vendor whose security team\'s emails appear in 30+ breaches and who clearly hasn\'t bothered changing their personal passwords is signalling something about operational maturity. This is a soft signal, not a hard disqualifier — but it correlates with other security-hygiene gaps.
Clean scan today does not mean you have not been compromised; it means your email does not appear in this specific aggregated breach corpus. New breaches are added continuously, breach data sometimes gets traded privately before being publicly aggregated, and the corpus is not exhaustive. Use clean scans as good news, not as proof of security.
This scanner queries publicly-disclosed breach databases, not actual dark-web sites. Real dark-web monitoring (Recorded Future, Flashpoint, etc.) crawls Tor markets and pays-for-access forums where data sometimes appears before public disclosure. For most personal use, breach-database monitoring is the right tool; for high-risk individuals (executives, public figures, journalists), enterprise dark-web monitoring is genuinely different and worth the cost.
The most common mistake after running a breach scan is doing nothing. The breach is in the past — the data is already out. The risk going forward is credential reuse, where attackers try the leaked password on other services. Change the password on the breached service AND any other service where you reused that password. Without that step, the scan was just curiosity, not security.
Most people have multiple email addresses across personal, work, and side accounts. Each needs separate breach checks. The personal Gmail you have used since 2008 might be in 40 breaches; the work email created last year might be in zero — but the work email is also less likely to be the target of credential stuffing. Check all your active email addresses, not just the one that most concerns you.
The share buttons share the count of breaches found, not which specific breaches. Posting "I have 47 breaches!" is fine. Posting "I have 47 breaches including LinkedIn 2012, Adobe 2013, Capital One 2019, and the LastPass dump" is unnecessarily helpful to attackers — it tells them which credential dumps to try against your other accounts. Keep specifics private.
This is a one-shot scan. New breaches happen continuously, and your email may appear in tomorrow\'s aggregator update. For ongoing awareness, either re-check quarterly manually, sign up for HaveIBeenPwned\'s free email-notification service, or use a paid monitoring service if automated alerts justify the cost. A check today is not protection against a breach disclosed next month.
