5 Best Pen Testing Companies in the USA

It is an undisputed fact that cyber-attacks are on the rise, making it necessary for companies of all sizes to take precautionary measures to protect their IT infrastructure.

One such measure is conducting a pen test of your digital assets like servers, web and mobile apps and APIs to identify and fix vulnerabilities.

This means you have to find a good pen tester who will guide you through the process and provide helpful reports to enable you to improve your company's security posture.

However, the challenge here is finding a suitable pen testing service provider that has the right certification and experience and provides cost-effective services.

This article makes it easy to find the right pen testing company quickly. It lists the five top penetration testing companies in the USA.

Do you want a certified penetration testing company with the right experience to scan your company's digital assets for vulnerabilities? At Microminder, we provide a deep pen testing service like no other.

What Is Penetration Testing?

A pen test is a security assessment of your IT infrastructure conducted by a suitable pen tester who uses tools and manual exploit techniques to identify real-world vulnerabilities and provides ways to fix them.

Pen testing aims to help companies discover where they are most likely to face an attack and proactively fix those weaknesses before hackers can exploit them.

What to Look for When Choosing a Pen Testing Company

The most important things to consider when choosing a penetration testing service provider are certifications, experience and price. Let's consider them one after the other


This is the first thing companies should consider when choosing pen testers because it proves that the vendor can do the job.

Many professional pen testing certifications are available, but CREST (Council of Registered Ethical Security Testers) is one of the most well-recognised bodies. You should ensure the pen tester is certified by a recognised body.

That is not all; you still have to vet the company further because CREST has a company-level certification and individual certifications. Each tester must pass an exam to prove their skills for the individual certifications.

Ask about the tester who will do the work to confirm if they have the appropriate certifications and experience.

And since CREST has a wide range of levels for individual testers, depending on your project complexity, you should choose an individual with the right level of certification.


Aside from certification, consider experience when choosing a pen testing company. The more pen testing the testers have done, the more proficient they become at discovering a wide range of security threats.

Not all pen-testing experience is equal. Some pen tests involve specific skills in rare technologies. Ensure that the tester has relevant experience in the technologies you are working with.

Also, you may need to be flexible because you may not find a pen tester with experience in every technology. Instead of focusing on a tester with a wide range of experience, choose someone who knows how to do pen tests on the technologies your company uses.


Companies often ask how much a penetration testing company will charge for the service.

Unfortunately, it is challenging to say how much pen testing costs because it depends on the size and complexity of a company's IT infrastructure. Also, it depends on what the pen testers will be working with and how deep they need to go. That is why most pen testing companies set their prices on a range.

For example, pen testing for web apps and SaaS sites can cost between $99 and $399. This indicates that there is no fixed price for penetration testing. Always choose a pen tester that offers the service at a competitive rate. But remember to consider certifications and experience first.
