Find out what scammers already know about you — without us holding your email.
The most thorough free breach-check tool on the public internet is Mozilla Monitor. They license the same breach data the paid tools sell and offer it free to consumers as part of Mozilla's mission. We surface it here instead of building our own because you deserve the best answer available — and the best answer isn't always ours.
Mozilla Monitor is not a Density6 product. Mozilla is an independent nonprofit. AEGIS has no commercial relationship with them, no affiliate code, no data-sharing arrangement, and no commission on signups.
A breach check tells you the bill has come due. AEGIS hands you a clean line.
AEGIS Personal issues you a dedicated number that lookup tools can't find.
Migrates your highest-risk accounts to the new line in a 15-minute call.
Replace-and-rotate within 24 hours (never later than 72) if the new line is ever compromised.
Both kinds of tools have their place. Run the free check first. If the answer is clean, great. If the answer is "your number is everywhere," come back.
The Free Gate tier is free, permanently, and you do not need a credit card to start. The Free Gate is $0 forever. No credit card is required.. Paying for a higher tier buys more volume and more leverage — it never unlocks a capability we were holding back.
