Pen testing courses can help you learn vulnerability assessment, network security, and ethical hacking techniques. You can build skills in penetration testing methodologies, risk analysis, and incident response strategies. Many courses introduce tools like Metasploit, Wireshark, and Burp Suite, that support identifying and exploiting security weaknesses in systems and applications. By engaging with these tools, you can practice practical work that enhance your ability to secure networks and protect sensitive data.
