Choosing the Right Penetration Test for Your Company

A Practical Guide

With data breaches filling the headlines on a daily basis, businesses in every industry are rushing to proactively assess their vulnerabilities and fortify their defenses.

Penetration testing, often referred to as pen testing, is a vital component of any robust cybersecurity strategy and is often the initial phase in establishing a comprehensive security program. It involves simulating cyberattacks on a company's systems and networks to uncover vulnerabilities and weaknesses before malicious actors can exploit them.

However, not all penetration tests are created equal. There are various types of pen tests, each tailored to address specific security concerns. In this blog post, we'll explore the different kinds of penetration tests and guide you on how to choose the best one for your company's unique needs.

Black Box Testing

Black box testing, also known as external testing, simulates a scenario where the tester has no prior knowledge of the company's infrastructure. This type of test evaluates the company's external-facing systems and applications, such as websites, without any inside information. It's an excellent choice for assessing how well your external defenses hold up against potential attackers.

When to choose: Opt for black box testing if you want to evaluate your external security posture and how your systems appear to potential adversaries from the outside.

White Box Testing

White box testing, or internal testing, is the opposite of black box testing. Testers have full access to internal information about your company's systems, networks, and applications. This type of pen test provides a more comprehensive assessment of vulnerabilities, as testers can take an in-depth look at the inner workings of your infrastructure.

When to choose: Consider white box testing when you want to evaluate the security of your internal systems and applications, identify architectural vulnerabilities, and assess the security of your source code.

Grey Box Testing

Grey box testing strikes a balance between black and white box testing. Testers have partial knowledge of your infrastructure, which may mimic the level of access an insider or a trusted user might have. This approach can uncover vulnerabilities that might be exploited by someone with limited access.

When to choose: Grey box testing is suitable for companies that want a realistic assessment of their security posture, combining elements of both external and internal perspectives.

Web Application Testing

Web application penetration testing focuses specifically on the security of web-based applications and websites. It examines vulnerabilities such as SQL injection, cross-site scripting (XSS), and authentication flaws that could be exploited by attackers targeting your web assets.

When to choose: If your company relies heavily on web applications or e-commerce platforms, web application testing is crucial to protect sensitive customer data and maintain the integrity of your online presence.

Network Penetration Testing

Network penetration testing assesses the security of your internal and external networks. It identifies vulnerabilities in network devices, configurations, and communication protocols that could be exploited by cybercriminals.

When to choose: Network penetration testing is essential for companies that need to safeguard their network infrastructure, including firewalls, routers, and switches, to prevent unauthorized access.

Social Engineering Testing

Social engineering tests the human element of your security. Testers use psychological manipulation to trick employees into revealing sensitive information or taking actions that could compromise security. This type of test is essential for understanding how well your staff can resist social engineering attacks like phishing.

When to choose: Incorporate social engineering testing to educate and train your employees on recognizing and thwarting social engineering attempts.

Choosing the Right Penetration Test

Now that you're familiar with the different types of penetration tests, here are some steps to help you choose the right one for your company:

1. Identify Your Objectives: Determine what you want to achieve with the penetration test. Are you looking to evaluate your external defenses, assess your internal systems, or test your employees' resilience to social engineering attacks?

2. Understand Your Assets: Know your critical assets and the technologies that support them. This information will help you select the most appropriate test type.

3. Assess Your Risk Tolerance: Consider your company's risk tolerance and regulatory compliance requirements when choosing a test. High-risk industries, like finance and healthcare, may require more comprehensive testing.

4. Budget Considerations: Your budget will also influence your choice. Different types of tests have varying costs, so select one that aligns with your financial resources.

5. Seek Professional Assistance: Engage with experienced penetration testing experts or consult with a cybersecurity service provider to help you make an informed decision. Book a complimentary security review with a Silent Breach expert to review your current state and develop a customized security roadmap.


By simulating a real-world attack, penetration testing is an invaluable tool for enhancing your company's cybersecurity posture. By understanding the various types of penetration tests and their respective strengths, you can choose the one that best suits your organization's needs. Remember, cybersecurity is a complex and dynamic process, and regular penetration testing is just one component in an overall security strategy to stay ahead of evolving threats and vulnerabilities.
