CREST Penetration Testing
A penetration test or pentest is a simulated cyberattack on your networks, systems, or applications. It is carried out by a Cyber Security professional and aims to identify any vulnerabilities before malicious actors can exploit them.
The duration of a penetration test can vary significantly, depending on factors such as the type, scope, and depth of testing required.
Certified by CREST and Offensive Security, our qualified testers employ real-world hacking techniques to uncover profound insights.

Factors Affecting the Duration of a Penetration Test
Below are factors impacting the length of a penetration test include:
- 1. Scope of the test
The size and complexity of the system being tested are significant factors on penetration test duration. A single server or small application will take a few days to assess. An entire network with multiple interconnected systems may take a week or more. When a test is focused on a specific area, such as a web application, the process will be faster than on examining an entire infrastructure.
- 2. Type of test
External tests focus on public-facing systems, such as email servers or websites. These typically take less time because of their smaller scope. Internal tests assessing security within an organisation’s network will typically cover more ground and require testers to navigate the company’s systems from an insider perspective.
- 3. Depth of testing
A basic vulnerability assessment can often be completed relatively quickly. A full-scale penetration test will typically exploit vulnerabilities to see how far an attacker could progress. This requires more time and resources and will typically take longer.
- 4. Team size and skill level
A larger team of highly experienced testers will usually complete a test faster than a smaller team. Experienced testers tend to be more efficient at identifying vulnerabilities and exploiting vulnerabilities. This can reduce the time it takes to conduct the testing process.
Typical Phases of a Penetration Test and How Long They Take
Penetration testing has a number of stages:
- 1. Initial discussions and scope testing
Before testing begins, objectives will be discussed and the scope defined. This includes the systems to be tested and the depth of testing. This phase will usually take one or two days but may be extended.
- 2. System exploration
Testers will then begin exploring the systems to understand the environment. This phase may last from a few hours to several days depending on the complexity of the systems.
- 3. Vulnerability discovery
Automated tools will be used to scan for vulnerabilities. Manual techniques will then be applied to verify the results. The phase can take several days or even weeks, depending on the complexity and scope of the test.
- 4. Exploitation
Testers attempt to exploit identified vulnerabilities to determine the potential damage that could be caused by a successful attack. The duration of this phase will depend on the extent and type of vulnerabilities identified.
- 5. Reporting and remediation advice
A detailed report is compiled after testing. This will outline any vulnerabilities, the impact they could have, and any recommendations to remediate these vulnerabilities.
How Long Does Each Type of Penetration Test Take?
The different types of penetration testing work to different timescales:
- 1. Web-based systems and applications
Penetration tests for web applications typically take 1–2 weeks. However, this can vary based on the app’s size, complexity, and the number of functionalities that require testing. Larger or more intricate applications may need extended testing periods to ensure thorough coverage.
- 2. Internal and external networks
The duration of internal network penetration testing can vary widely and is influenced by factors such as network complexity, security requirements, compliance needs, and data sensitivity. Smaller, less complex networks typically require less time, while larger or more intricate environments may demand a more extensive testing period. External testing is generally quicker than internal testing, though risk levels and regulatory factors can affect timelines for both. For a realistic timeframe, a preliminary assessment is often needed to determine the scope and specific requirements.
- 3. Wireless networks
The duration of wireless penetration tests varies widely and depends on factors such as network size, encryption type, access controls, and wireless coverage area. Smaller networks with basic encryption may require only a few days, while larger, more complex networks or those using advanced encryption and access controls may need closer to a week or more for thorough testing. An initial assessment is typically recommended to gauge the specific scope and time requirements.
- 4. Physical security
The timeframe for social engineering and simulated real-world attacks to assess physical security varies widely, depending on factors such as the organisation’s size, the complexity of security measures, the number of locations, and the sophistication of the scenarios involved. Some tests may be completed in a few days, while more complex engagements could require a week or longer. An initial scoping is generally advised to determine the appropriate level of testing and expected timeframe.
