“Find & Fix Security Weaknesses. Protect Networks, Systems & Apps from Cyber Threats”
Ethical hacking is like a security check-up for computers and networks. It's done to find and fix weaknesses before hackers can exploit them. Ethical hackers learn to test security, find vulnerabilities, and protect data. Their goal is to secure computers, networks, and sensitive information, reducing the risk of cyber attacks. By doing this, they help keep information safe and prevent hacking. Ethical hacking improves security, reduces risk, and protects data, making it an important job in today's digital world.
