Approach
Our Approach to Security & Prevention
Billions of private access data have already been stolen by hacking attacks and the number is increasing almost every day. Cybercrime is one of the biggest dangers.
Millions of private passwords regularly fall into the wrong hands. Since many users use their favorite password in many online services, hacking can have serious consequences. If the stolen password also gives you access to your bank account or other financial tools such as paypal. In these cases, hackers usually empty accounts within a very short time!
Specialists at the Federal Bureau of Criminal Investigations agree: If you are the victim of a hack, every second counts!
The problem: Many users do not even know that
one of their accounts has been hacked. A big risk, because in most cases, people whose passwords and access data have been stolen can prevent the worst by reacting quickly.
But how do you know if your account has been hacked? - HackCheck finds out for you!
HackCheck takes your email addresses and constantly checks if they belong to a hacking attack. In this case, the system tells you which online service has been compromised in which way - and recommends that you immediately change the password.
The system runs a new test several times per day and alerts you to new successful hacking attacks against your accounts. In this way, you can change the matching passwords immediately
before your own accounts are plundered.
