White Hat Hacker: What you need to know

Youve probably heard of hackers before. A distinction is made between different types of hackers. One type is the white hat hacker.

  • White hat hackers use their skills to find possible security flaws in the system. When these gaps are uncovered, a company can better protect itself from malicious attacks through system improvements.
  • Consequently, white hat hackers are deliberately used by companies to test their own operating and information systems by hacking them.
  • The hackers use methods that "evil" hackers would also use. For example, they send employees links that could lead to a malware infection.
  • For companies, white hat hackers are a significant asset. They ensure that there are fewer security gaps and downtimes in the systems and that they can be continuously developed and adapted to the standards.
  • Online companies in particular benefit from the work of white hat hackers. To keep customers safe, companies are developing high-quality malware protection, spyware removal tools, and a firewall to protect software. This must be as safe as possible.
