The Penetration Testing Execution Standard (PTES) provides both businesses and security service providers with a common language and scope for performing security evaluations. By establishing a clear baseline, PTES ensures that you know exactly what to expect during a penetration testing lifecycle, resulting in higher-quality and more consistent security assessments.
Before PTES, a lack of standardization often led to inconsistent testing and low-quality results. Today, PTES serves as a comprehensive guide for navigating the penetration testing process from initial scoping through final deliverables.
The PTES Lifecycle Flow
While penetration tests can vary widely depending on an organization's specific needs, the PTES framework standardizes the core lifecycle.

- 1
Determine Scope and Baseline
Define what type of testing is required and establish the minimum baseline of activities. PTES provides different "levels" of testing to accommodate organizations with higher security needs or specific industry requirements.
- 2
Execute the Penetration Test
Service providers perform the security evaluation. Because both parties have agreed on the PTES baseline, practitioners have clear guidance on the activities required to provide a quality service.
- 3
Deliver Standardized Reporting
A test is only as valuable as its results. The final phase involves delivering an integrated report that addresses the needs of all stakeholders.
Reporting is built-in: PTES mandates that reporting is not an afterthought. The standard explicitly requires both executive reporting (for business leaders) and technical reporting (for engineers and developers) as an integrated part of the lifecycle.
Who is PTES for?
The standard was designed to bridge the gap between those who need security services and those who provide them.
| Audience | Primary Goal |
|---|---|
| Businesses | Enables organizations to demand a specific, high-quality baseline of work when commissioning a penetration test, ensuring they receive genuine value. |
| Service Providers | Provides clear guidance on required activities, scoping, and deliverables to ensure a consistent, professional, and thorough service. |
PTES does not attempt to cover every possible edge-case scenario. Instead, it defines a rock-solid minimum baseline, with scalable levels built on top for complex environments.
Frequently Asked Questions
Who created the PTES standard?
The standard was initiated in early 2009 following industry discussions about the varying quality of penetration tests. It is maintained by a diverse group of information security practitioners, including CEOs, security analysts, and engineers from financial institutions, service providers, and security vendors.
Is the PTES group closed to new members?
Not at all. While the initiative started with a core group of about six people (growing to 20 at the first in-person meeting), the community actively welcomes new insights, down-to-earth opinions, and contributions from industry professionals.
Is this a formal standard?
Yes. The goal is to provide an actual, formal standard that businesses can rely on to understand exactly what type of testing they require and what baseline of quality they should expect.
