When attackers compromise the security of a website and succeed in producing a data leak, there usually appear information excerpts on sites allowing for anonymous publishing of data. By constantly monitoring such sites we manage to stay on top of email leaks as they take place, which will be helpful in mitigating the damage to our privacy that leaks of such nature may result in.
In checking your email address against our database we will cross-check it with all these sites and with those obtained from the rest of security breaches that have been fully verified.
If your email address comes up positive for any breach, this does not mean that your security has been compromised. We use an automatic process and this will always require review by a human being, for 100 % reliability. Take a look at the published information and check the real impact it has on your email.
