Phishing Domain Checker

Catch the brand + "login" domains attackers register to phish your customers.

See all checkers

Most phishing campaigns do not bother with subtle typos. They register an obvious-looking domain that combines your brand name with a word the victim expects to see — "login", "secure", "verify", "support", "account" — often on a cheap top-level domain like .xyz, .online or .top. To a customer skimming an email, brand-login.xyz or secure-brand-support.online looks plausible enough to click. A phishing domain checker generates those combinations the way an attacker would, then tells you which ones are actually registered and live.

What it checks

Your brand name combined with phishing keywords (login, secure, verify, account, support and more)
Both prefixes and suffixes, hyphenated, joined and subdomain-style variations
Cheap and abuse-prone TLDs (.xyz, .online, .top, .icu, .club …) alongside .com/.net/.org
Which candidate domains are actually registered and resolving
Risk signals on each live domain — whether it hosts a site, can send email (MX), and uses a credential keyword

Why it matters

A domain that pairs your brand with "login" or "secure" exists for one reason: to convince your customers it is you. Once it is live — especially if it serves a page and can send email — it is ready to harvest credentials or run invoice fraud in your name. These domains are usually registered shortly before a campaign launches, so spotting a brand-new one is often your earliest warning. Continuous checking turns that registration into an alert while you still have time to file a takedown.

How BrandSentryPro does it

Add your domain as a monitor and BrandSentryPro generates the combosquatting variants of your brand, checks which are registered via DNS, and scores each live hit by the signals that mark an operational phishing site. It re-checks over time and flags any newly registered or newly live domain, so you learn about an impersonation domain early — ideally before it is used against your customers.

Frequently asked questions

What is a phishing domain?

A phishing domain is one registered to impersonate a legitimate brand and trick people into entering credentials or payment details. They commonly combine the real brand name with a word like "login" or "secure" (for example brand-login.com), often on a cheap top-level domain.

How is this different from typosquatting detection?

Typosquatting detection finds character-level misspellings of your exact domain (like gooogle.com). Phishing domain detection finds combosquatting — your brand name combined with extra keywords and TLDs (like google-login.xyz) — which is the pattern most real phishing campaigns actually use. The two are complementary.

What should I do when a phishing domain is found?

Confirm whether it is impersonating you, capture evidence, and file an abuse/takedown request with its registrar and hosting provider. If it can send email, also brief your team and customers. Catching it early — before a campaign launches — gives you the best chance of a fast takedown.
