Kanary vs Mozilla Monitor (2026): which should you pick?

Pick Kanary if

• Fits if you're a public figure, executive or creator facing doxxing or harassment
• Works for families paying $125 a year for each added member on Core

Look elsewhere if

• Pricey if you just want fewer spam calls and junk mail, as Core is $250 a year and Advanced $500
• Skip it if you want to try it first: no free plan or trial, and the 30-day money-back guarantee covers the first month only
• Not for you if you live outside the US or UK, as it's built for US addresses and helps others case by case
• Watch out: weekly scans, unlimited custom removals and address confidentiality are Advanced options that may cost extra
• Tight if you won't answer identity checks: Kanary says hands-off members average 60 to 80% removals, against 90 to 95%

Pick Mozilla Monitor if

• Fits if you only want to know whether your email turned up in a breach
• Works for a family checking up to 5 addresses

Look elsewhere if

• Skip it if you want your details removed from people-search sites, as it doesn't do that
• Not for you if you want it to fix breaches, because the steps are yours to carry out
• Watch out: it monitors email addresses only, not phone numbers
• Watch out: Mozilla's help pages blocked our fetch, so we couldn't confirm whether a paid plan still exists

Kanary

• Built for US residents or people with a US address; Kanary says it has recently added UK users and helps others case by case.
• No free plan or trial; the 30-day money-back guarantee covers the first month only.
• Weekly and daily scans, unlimited custom removals and address confidentiality enrollment are Advanced options that may cost extra.
• Kanary says removal rates average 60 to 80% for hands-off members and 90 to 95% for those who answer identity checks.

Mozilla Monitor

• It checks breaches and does not remove personal information from people-search sites or data brokers; the pages we read mention no such service.
• It cannot resolve breaches for you: the steps, such as changing passwords, are yours to carry out.
• Monitoring is by email address; the pages we read do not list phone numbers or other identifiers.
• Mozilla's help pages blocked our fetch, so we could not confirm whether any paid Monitor plan still exists.

Kanary

Threat model per person

Kanary weighs each exposure by how likely it is to lead to doxxing, impersonation or phishing and works on those first, not only the easy opt-outs. It says it has covered more than 68,000 sites.

Search engines, brokers, social and AI

Core covers search engines and data brokers. Advanced adds social networks such as LinkedIn, X and YouTube, and AI chatbots, with full-site monitoring.

Google cleanup

After a source page is cleaned, Kanary asks Google to drop the link, handles Google's doxxing and harassment removals for sites that will not cooperate, and updates your Google settings to block new results.

Approve before removal

Unfamiliar results get a quick approve or deny check from you in the app, and known business-safe sites are skipped, which suits people who need a public profile.

Scans and reports

Core scans and sends removal requests monthly and emails a report once a month; Advanced scans weekly and reports twice a month, with live stats on the dashboard.

Escalations on Advanced

Advanced can enroll you in a state address confidentiality program, escalate stubborn sites to an attorney general and research active incidents. Some of these may cost extra.

Mozilla Monitor

Breach scan

Searches known data breaches using just an email address.

Guided resolution steps

Because fixing a breach usually means manual steps such as changing passwords or placing a fraud alert, it gives instructions instead of fixing exposures itself.

Alerts for new breaches

Checks each newly detected breach against your address and emails you if you are in it.

Five email addresses

All subscribers can monitor 5 email addresses at no cost.

Breach database

A public list of reported breaches since 2007, showing the date each was added and which data types it exposed.
