Welcome to the seventh installment of my Certification Series! After building a solid foundation in both technical IT and defensive security, it was time to explore the “other side” of the coin. That led me to the CompTIA PenTest+.

Overview of the CompTIA PenTest+ (PT0-003)

The PenTest+ has been updated to the PT0-003 version to keep pace with the evolving threat landscape. While the PT0-002 version focused on traditional on-premises vulnerabilities, the PT0-003 version expands significantly into specialized areas like cloud-native environments and JSON/Web API security.

The exam covers five modernized domains:

  1. Planning and Scoping (14%): Understanding the legal, organizational, and ethical complexities of a modern penetration test, including cloud-specific scoping.
  2. Information Gathering and Vulnerability Scanning (22%): Using automated tools and OSINT techniques to identify entry points, with a new focus on identifying vulnerabilities in serverless functions and APIs.
  3. Attacks and Exploits (30%): Performing a wide range of attacks across network, wireless, application, and cloud infrastructure. The PT0-003 version includes more complex scenarios involving containerized environments (Docker/K8s) and web application vulnerabilities like SSRF and IDOR.
  4. Reporting and Communication (18%): Effectively documenting findings and recommending remediation strategies that bridge the gap between technical and business stakeholders.
  5. Tools and Code Analysis (16%): Analyzing scripts and leveraging a broader variety of penetration testing tools. This domain now expects you to understand code snippets in Python, Ruby, PowerShell, and Bash.

Why Get the PenTest+ in 2026?

The PenTest+ remains the most well-rounded offensive certification for those wanting a structured methodology beyond just “running tools.”

  • Modern Offense: It bridges the gap between traditional network hacking and modern cloud/app-sec exploitation.
  • Methodology-First: Unlike some “capture the flag” (CTF) certifications, PenTest+ emphasizes the entire engagement lifecycle—from initial scoping to the final executive report.
  • Cross-Domain Mastery: It requires you to be equally comfortable at the Linux CLI, the Windows PowerShell prompt, and within a cloud management console.

Updated Study Materials

The PT0-003 version requires a more diverse lab environment than previous versions.

  1. Jason Dion’s PT0-003 Course (Udemy): Still the most comprehensive video course for the PenTest+ objectives, especially his new modules on cloud and API security.
  2. TryHackMe (Penetration Tester Path): THM remains the best place to practice the hands-on skills required for the PT0-003. Their labs on cloud security and web application vulnerabilities are essential.
  3. CompTIA PenTest+ Study Guide (Exam PT0-003): An excellent resource for understanding the “logic” of the new objectives and diving deep into the different scripting languages covered.
  4. Hack The Box (Academy - Web & Cloud Modules): I used HTB to practice the more advanced web application attacks (like SSRF and IDOR) that are now more prominent in the PT0-003 exam.

My Study Strategy

The PT0-003 version is all about diversity in your skillset.

  • Scripting Multi-lingualism: You don’t need to be a developer, but you must be able to read a script in Python, Ruby, Bash, or PowerShell and identify what it’s doing. Use resources like Exercism to get comfortable with the syntax of these languages.
  • Web API Focus: Spend time learning how to use tools like Burp Suite and Postman to interact with APIs. Understand how to identify common vulnerabilities in JSON-based communication.
  • Cloud Reconnaissance: Learn how to identify misconfigured S3 buckets, overly permissive IAM roles, and insecure cloud storage solutions.
  • Practice Reporting: Don’t just practice the hack; practice the report. Learn how to describe a technical vulnerability in a way that an executive can understand the business risk.

Exam Day and Difficulty

The PT0-003 is a challenging exam that requires both technical depth and a high-level understanding of the penetration testing lifecycle. The Performance-Based Questions (PBQs) often involve analyzing complex tool outputs and identifying the correct exploitation path in a multi-site topology.

Difficulty Rating: 8.5/10. The inclusion of cloud-native and API-specific attacks, along with a broader range of scripting languages, makes the PT0-003 a significant step up in complexity from the PT0-002 version.

Passing the PenTest+ (PT0-003) was a major milestone. It gave me a comprehensive perspective on offensive security and a solid foundation for more advanced, hands-on red teaming certifications.
