What Is Typosquatting Protection?

Typosquatting is registering a domain that looks like a company’s own domain, such as acrne.com for acme.com, to phish its staff or customers. Typosquatting protection flags those lookalike domains and gets the malicious ones taken down.

What Our Typosquatting Monitoring Watches

Our typosquatting monitoring flags four kinds of lookalike domain:

  • Homoglyph domains: domains that swap in look-alike characters, such as acrne.com, where “rn” reads as “m”.
  • Typo variants: the domain a slip of the keyboard produces, such as acmme.net.
  • Other TLDs: your name on a different top-level domain (the ending), such as acme.click.
  • Brand-name domains: your brand inside a longer domain, such as acme-login.net.
Table of the four lookalike domain types for acme.com: a homoglyph (acrne.com), a typo variant (acmme.net), another TLD (acme.click) and a brand-name domain (acme-login.net).

Monitoring acme.com catches fake versions of that domain, such as acrne.com and acme.click. To also catch domains that put a word next to your name, such as acme-login.net, add acme as a brand seed. A brand seed is a keyword of at least four characters that isn’t an everyday word. You can add a brand seed for your company name and another for each product name. Each seed counts as one monitored asset, the same as a domain.

We check newly registered domains against your monitored domains and brand seeds. We also check Certificate Transparency logs, the public list of every HTTPS certificate issued. A phishing site needs a certificate to run on HTTPS, so its domain shows up in those logs before the phishing page goes live.

How Breachsense Handles Each Typosquatting Threat

Credential Theft

A fake login page collects the passwords your staff or customers type into it. Our compromised credential monitoring sends an alert when a password typed into a phishing page matches your domains.

Phishing Campaigns

A lookalike domain gives an attacker a convincing sender address and link. We send an alert when the domain is registered, so your team can block it in email and DNS filters.

Malware Distribution

Software from a fake download page can be an infostealer instead of the app your employee wanted. When a stealer log contains credentials for your domains, we send an alert. The alert also includes the leaked credentials, malware family and infection date when the log records them.
Taking down a phishing site doesn’t tell you who already submitted their credentials to it. The takedown can also come too late. In our August 2026 phishing report, 50 of the 173 phishing kits that collected five or more passwords went quiet within a day. Each Breachsense alert shows whose password was stolen and from which phishing page, so you know which accounts to secure.
Example Breachsense /phish record in JSON: a masked username and password, the phishing page URL (kit_url) and the date we found the credential (fnd).

Who Uses Lookalike Domain Monitoring?

Every team below gets the same lookalike domain alert. Security teams block the domain. Brand, fraud and IP teams get it taken down.

  • BRAND PROTECTION

    Brand protection teams

    Spot lookalike domains when attackers register them. Breachsense takes down the malicious ones.

    What they use:
    lookalike domain alertsIP and hosting detailsdomain takedowns
  • SECURITY

    Security teams investigating phishing

    We send an alert when attackers register lookalike domains of your brand, so you can block them before users click. Query our API for any of your users' leaked credentials.

    What they use:
    lookalike domain alertsinfostealer log searchSIEM webhooks
  • FRAUD / IP

    Fraud and IP teams

    Catch lookalike domains when they're registered, before they host fake checkout pages or counterfeit storefronts. Breachsense handles the takedown.

    What they use:
    lookalike domain alertsIP and hosting detailsdomain takedowns
  • MSSP / MSP

    MSSPs and MSPs

    Add every client's domains and brand seeds to one Breachsense account. We send each client's lookalike domain alerts to that client's own webhook or inbox. Our dark web monitoring for MSPs covers leaked credentials under the same account.

How Breachsense Detects and Takes Down Typosquatting Domains

Add Your Domains

Add your domains and brand seeds through the Breachsense API, one call per asset. You can set a webhook or email address for each asset, so we send each brand’s or client’s alerts to the right team.

We Scan for Lookalike Domains

We check new domain registrations and Certificate Transparency logs continuously. Each alert shows which of your domains or brand seeds the new domain matched, so you know which brand the new domain targets.

Get Alerts

We send an alert for each lookalike domain by JSON webhook or HTML email. The webhook includes the domain and the date we found it. When the domain has an IP address or a CNAME (the host name the domain points to), the webhook includes those too. Point the webhook at your SIEM (security information and event management), SOAR or ticketing system to review the domain or block it with a SOAR playbook.

Take Down Impersonating Domains

When a lookalike domain hosts a phishing page impersonating you, tell us. We collect the evidence and handle the domain takedown. We price the number of takedowns you need each year into your quote.

Example Breachsense webhook alert in JSON for one lookalike domain: the monitored asset, the asm endpoint, the lookalike domain, its IP address, the date found and the type pphish (a potential phishing domain).

Frequently Asked Questions

Yes. When a typosquatting domain hosts a phishing page impersonating your brand, tell us. We collect the evidence and handle the domain takedown, so your team can focus on your core business. We also handle takedowns of clear-web sites that publish your leaked data.
We find a new lookalike domain when it’s registered, or when it gets its first HTTPS certificate. Both happen before an attacker can send a phishing email that links to the domain. An early alert gives your team time to block the domain in email and DNS filters before anyone clicks. How soon we send the alert after we find the domain depends on your package.
A typosquatting checker gives you a one-off list of possible lookalike domains each time you run it. A checker can also show which of those domains are registered. The list misses any lookalike domain registered after you run the checker. Typosquatting monitoring checks new registrations continuously. We send an alert when a new registration matches your domain or brand seed.
Yes. Breachsense sends an alert when a password typed into a phishing page matches your domains. Our phishing data comes directly from the phishing kit infrastructure we access. Our dark web monitoring also sends an alert when a stealer log contains credentials for your domains. Both kinds of alert cover the domains and email addresses you monitor. Each alert includes the plaintext password, so your team can check whether the employee still uses that password.
No. For brand impersonation, Breachsense monitors lookalike domains, not social media profiles. If fake social profiles are your main concern, add a brand protection service that monitors social platforms. Use Breachsense for the lookalike domains that phishing pages run on. If a fake profile links to a lookalike domain, we’ve already sent an alert for that domain when it was registered.
Breachsense doesn’t publish prices. On a demo call, we learn your requirements, then put together a package that covers only what you need. Each domain or brand seed counts as one asset. Our pricing page explains what sets the price. Trials are available after the demo.
