The Penetration Testing Execution Standard (PTES) provides a common language and scope for performing security evaluations. Adopting this methodology ensures your penetration tests deliver consistent, high-quality, and actionable results, regardless of who performs them.
Whether you are hiring a security firm or conducting assessments internally, PTES establishes a reliable baseline for what a penetration test should actually entail.
PTES was created in 2009 by a group of information security practitioners from financial institutions, service providers, and security vendors to combat the lack of standardization and low-quality work in the penetration testing industry.
Who benefits from PTES?
The standard is designed to serve two main audiences, bridging the communication gap between them:
| Audience | Primary Benefit | How to use it |
|---|---|---|
| Businesses | Quality Assurance | Use the standard to demand a specific baseline of work and clearly define expectations when hiring a service provider. |
| Service Providers | Clear Guidelines | Use the standard to understand exactly what activities are needed from initial scoping all the way through to final deliverables. |
The PTES Workflow
Adopting PTES means moving away from ad-hoc testing and embracing a structured lifecycle. Here is a high-level look at how a PTES-aligned engagement flows:

To start using the PTES methodology in your security assessments, follow these core phases:
- 1
Define the baseline and scope
Determine the minimum requirements for your basic penetration test. PTES defines a strict baseline that every test must meet, ensuring no critical steps are skipped.
- 2
Determine required security levels
Assess the target organization's industry and risk profile. While PTES provides a universal baseline, it also defines several "levels" on top of it. These levels outline the more comprehensive activities required for organizations with higher security needs.
- 3
Execute the assessment
Conduct the penetration test according to the agreed-upon baseline and advanced levels. This ensures practitioners have clear guidance on the quality and depth of service expected.
- 4
Standardize your reporting
A standard test is useless without a standard report. PTES requires you to generate two distinct types of reports: an Executive Report focused on business impact, and a Technical Report detailing the specific vulnerabilities, reproduction steps, and remediation guidance.
Always ensure your reporting structure is agreed upon during the scoping phase. Both the business and the service provider should know exactly what the final deliverables will look like before testing begins.
Frequently Asked Questions
Does the standard include all possible pentest scenarios?
While it is impossible to cover every edge case, PTES defines a comprehensive baseline for the minimum requirements of a basic pentest. It also includes several advanced levels tailored to different industries and higher security needs.
Is this a closed group or can I contribute?
PTES is an open community effort! It started with about 6 people and quickly grew. The creators welcome insight and down-to-earth opinions from the community.
Is this a formal standard?
Yes. The goal is to provide an actual, formal standard so businesses have a reliable baseline when purchasing a pentest, and practitioners have clear guidance to provide quality service.
