Penetration testing - a.k.a. “pentesting” - involves simulating attacks on networks and computer systems to identify vulnerabilities which can then be shored up by the cybersecurity team. Pen testing is a vital component of an organization’s information security strategy.

Pen testing certifications are professional credentials earned by IT security specialists who demonstrate a level of proficiency in this field. The leading pen-tester certificates are offered by various types of institutions, including cybersecurity industry associations, globally recognized certifying bodies, and technical training providers.

In this post, we will identify the best penetration testing certifications by experience level and specialization. For each certificate, we’ll highlight the key skills it covers, prerequisites, costs, benefits, training options, and more.

Benefits of Pen Testing Certifications

As cyber attacks continue to escalate in frequency and sophistication, organizations must ensure that their systems and data are secure. Pen-testing certifications validate an info-sec professional’s ability to protect these assets from attackers, providing certified pros with better career opportunities. From the company's perspective, employing certified penetration testers drives compliance, confidence in their employees' skills, and a competitive edge.

Advantages of pen testing certifications for individuals:

  • Validation of Current Skills: Certifications assure companies that you have a thorough understanding of the latest penetration testing tools, techniques, and methodologies.
  • Career Advancement: Certification is often a job requirement in this field. Certified pen testers are more likely to receive higher-paying jobs and promotions than their non-certified counterparts.
  • Credibility and Dedication: Certified pen testers gain credibility in the eyes of employers. Pursuing and earning a pentesting cert shows you’ve put in the time and effort to be on the cutting edge of this fast-moving space.

Organizational benefits of employing certified pen testers:

  • Compliance: Many public and private industries have compliance requirements that mandate the use of certified pros for penetration testing. For example, the Payment Card Industry Data Security Standard (PCI DSS) requires companies that handle credit card data to use certified pen testers.
  • Competitive Advantage: Companies that employ certified penetration testers demonstrate to clients and stakeholders that they take cybersecurity seriously and are committed to protecting their assets. This edge drives increased business opportunities and higher profits.

Offensive Security Experienced Penetration Tester (OSEP)

Best certification for expert pen testers.

Respected by hiring managers and technicians alike, Offensive Security (OS) is arguably the market leader in pen-testing training and certification. OS earned another spot in our top-five with their Offensive Security Experienced Penetration Tester (OSEP) credential, a rigorous expert-level pen testing certification. OSEP certification builds on the OSCP cert above, teaching learners how to perform high-level penetration tests against mature organizations with established security mechanisms. OSEP candidates must pass a grueling 48-hour, proctored exam inside a simulated corporate network to become certified.
