Penetration testing is a lot like hacking. Both involve scanning devices, software and wireless networks for tiny security vulnerabilities. The only difference is the underlying intentions: penetration testers work for tech companies, reporting any cybersecurity issues so they can get patched. Hackers intend to hack, and penetration testers intend to help. 

The line between the two is porous though. A multitude of hackers have parlayed major hacks into job offers. What better way to prove you’ll be a strong penetration tester than to actually penetrate a high-profile, allegedly “secure” system?

Top Penetration Testing Certifications

  • GIAC Certified Penetration Tester (GPEN)
  • GIAC Web Application Penetration Tester (GWAPT)
  • GIAC Exploit Researcher and Advanced Penetration Tester (GXPN)
  • EC-Council Certified Ethical Hacker (CEH)
  • EC-Council Licensed Penetration Tester — Master (LPT)
  • CompTIA PenTest+
  • Offensive Security Certified Professional (OSCP)

Well — there actually might be a better way. A history of hacking shows talent but seeds trust issues. A penetration testing certification offers another path — a way to show practical ability, but in a simulated environment that doesn’t embarrass prospective employers. Below, we’ve rounded up the 12 top penetration testing certification options.
