The Penetration Testing Execution Standard (PTES) provides a common language and scope for security evaluations. This guide outlines the seven core phases of a penetration test and explains the reporting expectations required to deliver actionable value to your organization.
Whether you are a business procuring a security test or a service provider executing one, understanding this lifecycle ensures high-quality, standardized results.

A successful penetration test is much more than just running automated tools. It is a structured process that combines technical security expertise with a deep understanding of your business.
- 1
Pre-engagement Interactions
Define the initial communication, reasoning, and scope behind the penetration test. This ensures both the testers and the organization are aligned on goals and rules of engagement.
- 2
Intelligence Gathering
Testers work behind the scenes to gather open-source intelligence (OSINT) and get a better understanding of the target organization's footprint.
- 3
Threat Modeling
Identify and categorize potential threats based on the intelligence gathered. This helps prioritize which assets and attack vectors require the most attention.
- 4
Vulnerability Analysis
Actively research and discover flaws in the systems, applications, or networks that could be leveraged by an attacker.
- 5
Exploitation
Apply technical security expertise to actively exploit the discovered vulnerabilities, proving the real-world risk they pose to the organization.
- 6
Post Exploitation
Determine the value of the compromised systems and maintain access. This phase combines technical success with business understanding to show the true impact of a breach.
- 7
Reporting
Capture the entire process in a comprehensive document that makes sense to the customer and provides actionable remediation steps.
Adjusting Intensity Levels
No two penetration tests are exactly alike. While the standard defines a baseline, testing can range from a mundane web application assessment to a full-scale red team engagement. Future iterations of the standard include "levels" of intensity, enabling you to define how much sophistication you expect an adversary to exhibit.
Reporting Requirements
Providing a standard for the test without defining how the report is delivered would be useless. The reporting phase is designed to translate highly technical findings into business risk.
Every standardized penetration test must include two integrated reporting components:
| Report Type | Target Audience | Purpose |
|---|---|---|
| Executive Reporting | Business leaders, C-Suite, Management | Summarizes the overall risk, business impact, and high-level strategic recommendations without getting bogged down in technical jargon. |
| Technical Reporting | IT staff, Developers, Security Engineers | Details the exact vulnerabilities found, the steps taken to exploit them, and granular, actionable remediation guidance. |
A high-quality penetration test report should never just be an exported list from an automated vulnerability scanner. It must capture the context of the entire lifecycle, from threat modeling to post-exploitation.
Frequently Asked Questions
Who is the intended audience for this standard?
There are two main communities: businesses that require the service, and service providers. For businesses, the goal is to enable you to demand a specific baseline of work. For service providers, it provides a baseline for the activities needed from scoping through reporting.
Does the standard cover all possible pentest scenarios?
While it cannot possibly cover every edge case, the standard defines a baseline for the minimum requirements of a basic pentest. It also provides several "levels" on top of the baseline for organizations with higher security needs.
Why was this standard created?
The lack of standardization was hurting the industry. Businesses were receiving low-quality work, and practitioners lacked guidance on what was needed to provide a quality service. PTES was created by industry practitioners to solve this problem.
