Penetration testing is a process that many organizations go through to test their security. It’s important for you to understand what penetration testing is, how it works, and when your organization should have one done. In this article, we’ll cover the basics of what penetration testing is, who needs them, how they work, and where you can find the top 5 penetration testing providers in the US.

What is Penetration Testing?

This is the process of attempting to penetrate a computer system or network to find security weaknesses and loopholes. These tests can be done manually by testers who are skilled in penetration techniques, or they can be automated with tools that scan systems for known vulnerabilities.

Types of Penetration Testing

There are three main types of penetration tests:

Black Box Tests

In a black-box test, the tester faces the target environment like a real hacker as they would have no prior knowledge of the system or network being tested. This type of testing requires more time as the tester first needs to gather information on the systems.

White Box Tests

A white box test is conducted with complete knowledge of the system being tested. Testers have access to everything including source code, passwords, and network diagrams. This type of test is often used to find vulnerabilities that may exist within the organization’s internal systems.

Gray Box Tests

Gray box testing combines both strategies of black and white box testing. Testers only have some knowledge of the system. This type of test is often used to find vulnerabilities that may exist between an organization’s internal systems and its external systems.

How do Penetration Tests Work?

The process of conducting a penetration testing can vary depending on the type of test being performed and the organization’s specific needs. However, there are typically three phases: reconnaissance, exploitation, and reporting.


In the reconnaissance phase, testers gather information about the target system including IP addresses, ports, services running on those ports, user accounts, and passwords. This can be done manually or with the help of automated scanning tools.


In the exploitation phase, testers attempt to exploit the vulnerabilities that were discovered in the reconnaissance phase. Manual and automated penetration testing can be done and we suggest doing both.


In the reporting phase, testers compile all of their findings into a report and provide recommendations for how to fix the vulnerabilities that were found.

Benefits of Penetration Testing

There are many benefits of penetration testing including:

  • identifying security weaknesses before an attacker does
  • verifying the effectiveness of security controls
  • training employees on how to defend against attacks
  • identifying potential areas of risk
  • determining compliance with regulations

Who Needs Penetration Testing?

Any organisation that has a computer system or network should consider performing a penetration test. However, some organisations are required by law to perform pen tests. These organisations include:

  • financial institutions
  • healthcare organisations
  • government agencies
  • companies that handle credit card data

When should your organization perform a penetration test?

Ideally, you should perform penetration tests regularly and certainly before you are attacked. However, even if you have already been attacked, it’s not too late to perform a pen test. A general rule is to perform pentests once every year.
