Penetration Testing Top Rated 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.
Choosing the right Penetration Testing Company
In this article, we review Penetration Testing companies and mainly focus on USA based controlled pen-testing service providers.  Each company on the list provides penetration testing as one of their core services. Expanded in this article we identify in depth service offerings of the top penetration testing companies . Although we have included a list of the best penetration testing companies world-wide, our in depth review of the top ranked pen-testing companies are within the USA.  If you are a USA firm seeking a trusted cybersecurity partner who provides controlled penetration testing based in the USA, than this article will help you discover the top USA Penetration testing companies.

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

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.

Different Types of Penetration Tests

  • External or Internal Network Penetration Testing
  • Web Application Penetration Testing
  • Mobile Application Penetration Testing
  • ICS/ SCADA Penetration Testing
  • IoT and Internet-Aware Device Testing
  • Social Engineering/ Client Awareness  Penetration Testing

Penetration Tests

Many Penetration tests performed by the Top Penetration Testing Companies will include common hacking techniques and may or may not include the use of automated Penetration Testing tools along with manual Penetration Testing.
  • Generic vulnerability tests: Attempt to determine the presence of known vulnerabilities and to exploit them. This includes vulnerabilities related to legitimately provided services such as HTTP, FTP, SMTP mail exchangers and gateways, DNS, IMAP/POP, file and print sharing services, etc.
  • Network characteristics and topology tests: Attempt to determine the presence and exploit vulnerabilities relate to network topology, network components configuration and design principles and protocol specific characteristics. These includes tests that consider spoofing techniques, protocol specific tests such as usage of IP options, fragmentation, exploit of trust relationships, protocol encapsulation, routing tricks, design and implementation flaws in several network protocols and related services, etc.
  • Miss-configuration tests: Attempt to identify and exploit typical miss-configuration problems.
  • VLAN Isolation: Verify that the different functional network segments are physically or logically isolated. For example, that the servers and workstations are isolated on the target network.

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].

OWASP Top 10 Most Critical Web Application Security Risks

The OWASP Top 10 is a powerful awareness document for web application security. It represents a broad consensus about the most critical security risks to web applications. Project members include a variety of security experts from around the world who have shared their expertise to produce this list.

We urge all companies to adopt this awareness document within their organization and start the process of ensuring that their web applications minimize these risks. Adopting the OWASP Top 10 is perhaps the most effective first step towards changing the software development culture within your organization into one that produces secure code.

Open Source Security Testing Methodology Manual (OSSTMM)

OSSTMM is a methodology to test the operational security of physical locations, workflow, human security testing, physical security testing, wireless security testing, telecommunication security testing, data networks security testing and compliance. OSSTMM can be supporting reference of IOS 27001 instead of a hands-on penetration testing guide.

OSSTMM includes the following key sections:

    • Operational Security Metrics
    • Trust Analysis
    • Work Flow.
    • Human Security Testing
    • Physical Security Testing
    • Wireless Security Testing
    • Telecommunications Security Testing

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.

Finding the right trustworthy penetration testing firm is not a hard task if you do your homework. There are many pen-testing companies based in the USA that provide controlled penetration testing. To identify the best penetration testing firm for your project you should consider experience, credentials, scoping documentation and customer service quality. Once you have identified the best penetration testing firm for your project, the report delivered is just as important of the quality of the test. Penetration Testing Reporting should include remediation recommendations and vulnerabilities should be classified as Critical, High, Moderate, Low and Informational. Here are some additional things to consider when reviewing Penetration Testing Companies:

Important Penetration Testing Checklist when searching for the Best Penetration Testing Company for your Project:

  • Are the engineers assigned to your project Senior Level or Junior Level
  • What is the time-box for the testing period?
  • Is your budget in place
  • What are your goals of the test? (e.g. escalation of privileges, proof of defacement, proof of critical system access
  • Compliance requirements
  • Report Audience ( Executive level reporting, technical reporting, Customer facing redacted Pen-test report)
  • Specialty Penetration testing (ICS/SCADA, IoT)
  • Retesting requirements ( are retests built into service/ statement of work)

Redbot Security Featured Penetration Testing Services: Internal Penetration Testing

Internal Penetration Testing is a proactive step your company can take to ensure the security of your internal networks. Redbot Security will perform the following steps:

  • Reconnaissance and Enumeration focuses on trying to identify targets for the assessment using passive means. For the internal assessment, we will use sniffing tools to identify unencrypted services such as FTP and Telnet as well as passwords or other sensitive data/credentials being passed in clear-text.
    • Tools Include: Discover, domainCat, domainhunter, Egress-Assess, EyeWitness, httpscreenshot, InSpy, knock, linkScrape, MailSniper, ruler, SimplyEmail, Metasploit Framework modules, Kali Linux and custom scripts.
  • Network Surveying and Services Identification is the process of using methods such as port scanning, service and OS fingerprinting, and vulnerability scanning. This will help Redbot Security identify open ports, protocols and services throughout the environment and enumerate the attack surface. During this phase Redbot Security will fingerprint and catalog versioning information on all protocols and services available as well as any present vulnerabilities.
    • Tools Include: Nexpose, Nmap, Wireshark, Unicornscan, Xprobe2, Hping3, ike-scan, Scapy, Kali Linux and custom scripts.
  • Network Penetration Testing will use the data gathered in previous phases to develop an attack plan. The attack plan will consist of version and signature-based vulnerabilities, manually identified and chained attacks, as well as other attacks identified by the testers. Furthermore, the attack plan and execution can be tailored to account for organization-specific threat agents. The attack plan is then executed focusing on gaining access to systems and data. Once initial access is gained the goal shifts to escalate privileges to make the attack more pervasive and gain access to sensitive assets and information.
    • Tools Include: Nmap, Metasploit, CrackMapExec, PowerSploit, Empire, BurpSuitePro, Veil, sslScrape, SIET, BloodHound, Sharphound, SIET, unicorn, dnsenum, Burpsuite Pro, enum4linux, impacket, Responder, Wireshark, Unicornscan, Inguma, Kali Linux and custom scripts.
  • Password Cracking is typically conducted in conjunction with the network penetration testing phase. Services with authenticated logins are tested against a dynamic username and password list tailored to the organization based on information gathered in previous phases and industry password security trends. The goal of this aspect of the assessment is to obtain access to services and devices that are not available through configuration error and/or vulnerability exploitation.
    • Tools Include: Metasploit, Hydra, Medusa, Hashcat, John the Ripper, SSHater, rcrack, WyD, Kali Linux and custom scripts.
  • Root Cause Analysis and Reporting for compiling the results of the penetration testing and building comprehensive findings for all issues found. Redbot Security will provide analysis and reporting of each identified risk with documented attack chains and proofs-of-concept (PoCs).
