Complete guide: How to choose the best penetration testing company

Following a systematic approach and asking the right questions, you can identify the ideal partner to safeguard your organization against cyber threats.

This comprehensive guide equips you with step-by-step instructions and valuable questions to consider, ensuring you select the best pentesting partner for your organization’s unique needs.

Not sure what type of security testing service you need?

Step 1: Define your needs

Begin by clearly outlining your goals and objectives for the penetration testing engagement. Determine what you aim to achieve, whether identifying vulnerabilities in specific systems, complying with regulatory requirements, or enhancing overall security posture.

Valuable questions to consider:

  • What systems need testing? (Web applications, mobile apps, network infrastructure, cloud environments, etc.)
  • What is your desired scope? (Black-box, white-box, gray-box testing)
  • Do you have industry compliance requirements? (PCI DSS, HIPAA, etc.)
  • What is your budget?

Step 2: Assess expertise and experience

Evaluate the expertise and experience of potential pentest companies. Look for firms with a proven track record of success, extensive experience in your industry, and certifications such as Certified Ethical Hacker (CEH), Offensive Security Certified Professional (OSCP), or Certified Information Systems Security Professional (CISSP).

Valuable questions to consider:

  • How long has the company been in the penetration testing industry?
  • Can they provide references or case studies from similar projects?
  • What certifications and qualifications do their pentesters hold?

Step 3: Review methodologies and tools

Understand the methodologies and tools employed by each company during penetration testing. Ensure they utilize industry-standard frameworks such as NIST SP 800-115 or OSSTMM and employ manual and automated testing techniques for comprehensive coverage.

Valuable questions to consider:

  • What methodologies and frameworks do they follow during pentesting?
  • Do they utilize a combination of automated and manual testing techniques?
  • Are their tools and techniques up-to-date with the latest industry standards?

Step 4: Evaluate reporting and communication

Assess the clarity and comprehensiveness of the reports provided by each pentest company. Look for detailed findings, prioritized recommendations, and actionable insights to enable your team to remediate vulnerabilities effectively. Additionally, consider their communication style and responsiveness throughout the engagement.

Valuable questions to consider:

  • What does their typical penetration testing report include?
  • How do they prioritize and categorize identified vulnerabilities?
  • How do they communicate findings and recommendations to stakeholders?

Step 5: Consider cost and value

While cost is an important factor, prioritize value over price when selecting a pentest company. Consider the breadth and depth of services offered, the quality of deliverables, and the long-term benefits of partnering with a reputable firm that prioritizes your organization’s security.

Valuable questions to consider:

  • What is the pricing structure for their penetration testing services?
  • Do they offer additional services or support beyond the initial engagement?
  • How does their pricing compare to other reputable pentest companies in the market?

Frequently Asked Questions

What is the penetration testing cost?

The cost of penetration testing can vary widely depending on factors such as the scope of the test, the complexity of the systems being tested, and the expertise of the pentesting company. On average, a penetration test can range from a few thousand dollars to tens of thousands.

What is the usual process for pentest?

The usual process for a penetration test typically involves the following steps:

  • Planning and scoping: Defining the test’s objectives, scope, and targets.
  • Information gathering: Collecting relevant information about the target systems and infrastructure.
  • Vulnerability analysis: Identifying and assessing vulnerabilities in the target systems.
  • Exploitation: Attempting to exploit identified vulnerabilities to gain unauthorized access or perform other malicious activities.
  • Reporting: Documenting findings, including vulnerabilities discovered, potential impact, and recommended remediation steps.
  • Remediation: Assisting the client in addressing and fixing identified vulnerabilities to improve their security posture.
What are the types of pentests?

There are three main types of penetration tests, each with a different approach:

  • Black Box Testing: Simulates an external attacker without prior knowledge of your systems.
  • White Box Testing: The pentest team fully knows your systems and internal controls.
  • Gray Box Testing: A hybrid approach where testers have some knowledge of the systems.
What is the difference between a vulnerability scan and penetration testing?

A vulnerability scan is an automated process that identifies known vulnerabilities in systems or applications by scanning them for common security issues. Penetration testing involves simulating real-world attacks to identify and exploit vulnerabilities in a controlled environment. While vulnerability scanning provides a broad overview of potential security risks, penetration testing offers a more comprehensive assessment by attempting to exploit identified vulnerabilities and assess their impact.

Can penetration testing disrupt business operations?

If conducted properly, penetration testing should not disrupt business operations in most cases. However, disruption is possible, especially if critical systems are targeted or testing is performed during peak business hours. To minimize the risk of disruption, penetration tests are often scheduled during off-peak hours, and appropriate precautions are taken to ensure that testing activities do not impact production systems or services. Additionally, communication and coordination between the pentesting team and the organization’s IT staff can help mitigate any potential disruptions.
