Top Rated Penetration Testing Companies 

Why is Penetration Testing Important:
Cyber threats have increased dramatically over the last few years, and cyber criminals have easy access tools to breach organizations of any size. Smaller businesses are considered “low hanging fruit” to hackers, but as we’ve seen mid-sized and enterprise are not as equipped as they should be to handle the current threat landscape. One of the most powerful strategies a company of any size can implement is of course penetration testing.

Here is a list of the top rated penetration testing companies for you to choose the best pen-testing company for your project

According to NIST – the National Institute of Standards and Technology, Penetration testing can be invaluable, but it is labor-intensive and requires great expertise to minimize the risk to targeted systems. Systems may be damaged or otherwise rendered inoperable during the course of penetration testing, even though the organization benefits in knowing how a system could be rendered inoperable by an intruder. Although experienced penetration testers can mitigate this risk, it can never be fully eliminated. This is why choosing a Senior Level penetration testing team for your project is a crucial step.
Choosing the Best Penetration Testing Company for your project 
In this article, we review the Best and top- rated Penetration Testing firms based on a set of controls, and mainly focus on USA based controlled pen-testing service providers.  Each Pen-Testing company on the list provides world-class penetration testing as their core services. There are many Network Penetration Testing Companies and Application ‘Pentest’ Companies, however not all provide Manual Controlled Pen-testingExpanded in this article we identify in depth service offerings of the top penetration testing companies who focus on true manual hacking methods,  however we do not list the variety of vulnerability scanning companies or junior level service teams.   We have also included a list of the best penetration testing companies world-wide, however keep in mind our in depth review of the top ranked pen-testing companies are all within the United States.  If you are a USA firm seeking a trusted cybersecurity partner who provides controlled penetration testing based only in the USA, than this article will help you discover the top USA Penetration testing companies.  This article is updated monthly.

Penetration Testing – Definition

Penetration Testing or pen testing is a method of testing an organization’s data defense from a controlled ethical hacking environment.  Scope of the penetration test is defined and a penetrating testing company will attempt to hack into a company’s network to expose and exploit organization’s network weaknesses.With the rise of threats, many ‘would be cyber’ companies are jumping on the cyber security bandwagon, offering a variety of  solutions to the market place, often times ill equipped and lacking the proper experience to successfully manage the right cyber security solutions and proactive network security testing.

The penetration testing process typically identifies a target system and identifies particular goals, The testing team performs discovery of that system or systems and then attempts to achieve the penetration testing  goals. A penetration test project might be white box  penetration test (which provides credentials and network information, typically used for insider threat assessments) a black=box pen-test (provides no information other than targeted system, ie web app IP address) and a gray-box penetration test which would be a combination of both black-box and white-box Penetration testing (where some information  is shared with the penetration testing team). A penetration test is a proactive assessment that help determine if  a system is vulnerable to attack by bad actors (hackers, criminals, terrorists etc)

A Penetration test will identify the potential impact of vulnerabilities to the organization and recommends proper remediation efforts to fix the vulnerabilities to ultimate reduce risk. Without proper knowledge, many times a vulnerability test will show too many false positives leaving IT confused and in a state of perpetual worry.  A true manual penetration test shows only the verified vulnerabilities, potentially chained together for exploits with proof of concept for each

The National Cyber Security Center, states that penetration testing  is defined as “A method for gaining assurance in the security of an IT system by attempting to breach some or all of that system’s security, using the same tools and techniques as an adversary might.”

When should your organization perform a Penetration Test?

  • Perform Penetration Testing with the addition of new network infrastructure devices or applications
  • Upgrades, Modifications, Patches, Firewall Changes made to infrastructure and applications
  • When Policy, Compliance and regulation changes. its time to order a penetration test
  • New locations should be Pen-tested

Discover Gaps In Compliance

Using penetration testing as a means to identify gaps in compliance is a bit closer to auditing than true security engineering, but experienced penetration testers often breach a perimeter because someone did not get all the machines patched, or possibly because a non-compliant machine was put up “temporarily” and ended up becoming a critical resource. In today’s heavily regulated environment, many organizations are looking for better ways to continually assess their compliance posture. Most regulations have multiple components specifically related to system auditing and security.
Top Rated Penetration Testing Companies typically have the ability to scope a wide range of projects. When searching for the Best Penetration Testing Company for your project, you’ll need to clearly define your goals and expectations.  Larger Penetration Testing Firms might turn away your project if it is on the smaller scale, since their top engineers are working on larger, more time intensive projects.

Research and hiring a penetration testing company for your project.

Penetration testing is controlled security testing in which the engineer will mimic real-world attacks to identify methods for circumventing the security features of an application, system, or network. Based on the Penetration Testing company that you hire, Penetration Testing almost always involves launching real world attacks on real systems and data that use tools and techniques commonly used by attackers. Knowing that your systems will be attacked, it then becomes critical that you hiring only the best Sr. Level Penetration Testing company that fully understands your systems. In addition, it is vitally important that the team you hire is engaged, reachable (within the United States) and has a solid communication plan in place.

Most penetration tests involve looking for combinations of vulnerabilities on one or more systems that can be used to gain more access than could be achieved through a single vulnerability. This is important to understand when selecting an experienced penetration testing company.  Junior level engineers or vulnerability scanning companies (the ones that offer 1 size package fits all) typically do not know how to chain together a combination of different vulnerabilities to achieve exploitation.  Special Note: These type of reports (Vulnerability Reports disguised as Penetration tests) are usually excessive and contain many false positives and irrelevant information. Your IT team will be lost in a sea of paperwork and fluff. (For more information on the difference between vulnerability scanning vs a penetration test, please visit here.)

In addition, many manual controlled Penetration tests  will determine if  your systems are able to tolerate real world-style attack patterns.  Obviously knowing this, it becomes an even more sensitive testing engagement when the systems are legacy and potentially operate critical infrastructure. Learn more about ICS/SCADA Testing here.

Attackers are sophisticated and are always seeking new methods to exploit their victims.  Penetration testing companies need to continually be updated and researched on new methods and exploits in order to out pace the current threat environment. Check out some useful fixes (easy)  that will immediately help to secure your network here.

NIST states: “Penetration testing can be invaluable, but it is labor-intensive and requires great expertise to minimize the risk to targeted systems. Systems may be damaged or otherwise rendered inoperable during the course of penetration testing, even though the organization benefits in knowing how a system could be rendered inoperable by an intruder. Although experienced penetration testers can mitigate this risk, it can never be fully eliminated. Penetration testing should be performed only after careful consideration, notification, and planning.”

Other types of Penetration testing often include non-technical methods of attack. For example Redbot Security is one company that provides simulated breaching of physical security controls and procedures that a company may have in place.  Goals could be to connect to a network, steal equipment, capture sensitive information (possibly by installing keylogging devices), or disrupt communications. Learn More about Physical Security Penetration Testing Here.

NIST 800 Warns “that caution should be exercised when performing physical security testing—security guards should be made aware of how to verify the validity of tester activity, such as via a point of contact or documentation. Another nontechnical means of attack is the use of social engineering, such as posing as a help desk agent and calling to request a user’s passwords, or calling the help desk posing as a user and asking for a password to be reset. “

For Addition Penetration Testing Information and Penetration Testing Reference Material:

NIST SP 800-115

“Penetration testing can be useful for determining:

  • How well the system tolerates real world-style attack patterns
  • The likely level of sophistication an attacker needs to successfully compromise the system
  • Additional countermeasures that could mitigate threats against the system
  • Defenders’ ability to detect attacks and respond appropriately.

Penetration testing can be invaluable, but it is labor-intensive and requires great expertise to minimize the risk to targeted systems. Systems may be damaged or otherwise rendered inoperable during the course of penetration testing, even though the organization benefits in knowing how a system could be rendered inoperable by an intruder. Although experienced penetration testers can mitigate this risk, it can never be fully eliminated. Penetration testing should be performed only after careful consideration, notification, and planning”


Industrial control systems (ICS), including supervisory control and data acquisition (SCADA)

ICS are found in many industries such as electric, water and wastewater, transportation, oil and natural gas, chemical, pharmaceutical,  and manufacturing (e.g., automotive, aerospace, etc). Because there are many different types of ICS with varying levels of potential risk and impact, there are many different methods and techniques for securing ICS, among them is Penetration Testing.

Examples of potential consequences of an ICS incident:

*  Impact on national security—facilitate an act of terrorism.
*  Reduction or loss of production at one site or multiple sites simultaneously.
*  Injury or death of employees.
*  Injury or death of persons in the community.
*  Damage to equipment.
*  Release, diversion, or theft of hazardous materials.
*  Environmental damage.
*  Violation of regulatory requirements.
*  Product contamination.
*  Criminal or civil legal liabilities.
*  Loss of proprietary or confidential information.
*  Loss of brand image or customer confidence.

The security controls that fall within the NIST SP 800-53 Risk Assessment (RA) family provide policy and procedures to develop, distribute, and maintain a documented risk assessment policy that describes purpose, scope, roles, responsibilities, and compliance as well as policy implementation procedures. An information system and associated data is categorized based on the security objectives and a range of risk levels. A risk assessment is performed to identify risks and the magnitude of harm that could result from the unauthorized access, use, disclosure, disruption, modification, or destruction of an information system and data. Also included in these controls are mechanisms for keeping risk assessments up-to-date and performing periodic testing and vulnerability assessments.

Supplemental guidance for the RA controls can be found in the following documents:

NIST SP 800-30 provides guidance on conducting risk assessments and updates [79].
NIST SP 800-39 provides guidance on risk management at all organizational levels [20].
NIST SP 800-40 provides guidance on handling security patches [40].
NIST SP 800-115 provides guidance on network security testing [41].
NIST SP 800-60 provides guidance on determining security categories for information types [25].
NIST SP 800-100 provides guidance on information security governance and planning [27].

Application Software Security – 11 recommended implementation measures:

  1. Patching
  2. Implement a Web Application Firewall (WAF)
  3. Error checking all input
  4. Use an automated scanner to look for security weaknesses
  5. Output sanitization of error messages
  6. Segregation development and production environments
  7. Secure code analysis, manual and automated
  8. Verify vendor security processes
  9. Database configuration hardening
  10. Train developers on writing secure code
  11. Remove development artifacts from production code

While many controls are definitely of a technical nature, it is important to distinguish the way in which controls differ from coding techniques. Many things we might think of as controls, should more properly be put into coding standards or guidelines. As an example, NIST SP800-53 suggests five controls related to session management:

  • Concurrent Session Control
  • Session Lock
  • Session Termination
  • Session Audit
  • Session Authenticity

Note that three of these are included within the category of Access Controls. In most cases, NIST explicitly calls for the organization to define some of the elements of how these controls should be implemented.

What are the stages in a penetration test?2022-07-30T15:14:33+00:00

The Six Stages of Penetration Testing

  • Discovery. The first phase of penetration testing is OSINT and Discovery.
  • Testing. Testing phase is performed by qualified engineers that utilize both automated and manual exploitation testing techniques and tools
  • Assessment. Determine Risk to organization
  • Knowledge Sharing.  Provide clear results with Remediation planning
  • Remediation.  Organization remediates findings that pose a risk.
  • Retesting. Retesting of remediated vulnerabilities and final report delivery
What is Penetration Testing?2022-07-30T15:09:17+00:00

Definition: Penetration Testing simulates a hacking attack and is usually performed by qualified penetration testing engineers.  The simulated attack will test the security of networks, applications and devices. Many qualified Penetration testing engineers utilize the same tools and techniques that a malicious actor will use in the real world.  Once the Penetration Test is complete the business is able to access and remediate vulnerabilities that were found within their systems.

How often should a company perform a cybersecurity test?2022-03-08T16:37:56+00:00

Typically a company should test their network, applications and devices when the company has added new network infrastructure devices or applications. Additionally, when Upgrades or Modifications are made to infrastructure,  a Penetration Test should be performed.  New Policies, Compliance, and Regulation changes also dictate when a company should perform cybersecurity testing. NIST SP 800-53 includes recommendations for keeping risk assessments up-to-date and performing periodic cybersecurity testing.

What is the most effective cybersecurity test?2022-03-08T16:35:29+00:00

One of the most powerful cybersecurity testing strategies a company of any size can implement is called a penetration test.  Cyber threats and data breaches have increased dramatically over the last few years, and cyber criminals have advanced skills, tools and the ability to exploit critical data and systems. A penetration test, or pen-test , is a controlled exercise that simulates a malicious hacking attack on a computer system, network, application or device and is performed to help evaluate the cybersecurity controls that are in place, that defend the system, device or application.
