Penetration Testing vs. Red Teaming: 6 Key Differences

Cybersecurity is a high-stakes battle, and the nuances between different assessment methodologies are incredibly important for effective defense. In this regard, red teams and penetration testing stand out as two of the most important practices for identifying vulnerabilities and strengthening existing security. 

While both test methods seek to find weaknesses in a company's defenses, they are structured around different philosophies and strategies. In this article, we’ll outline the key differences between red teaming and penetration testing, and provide recommendations for using both techniques.

What is Penetration Testing?

Penetration testing, or more colloquially “pen testing” is the practice of hiring a friendly hacker to test a corporation's defenses. Basically, it consists of engaging ethical hackers in simulated attacks with the goal of exposing vulnerabilities in systems and networks. To put it in very basic terms, think of it as a kind of methodical stress test that you go through to test your security.

Penetration testing helps organizations identify security gaps in specific areas, such as applications or networks, providing a clear roadmap for remediation. By mimicking the techniques a cybercriminal would use, a penetration tester provides constructive feedback and insightful recommendations to help an organization strengthen its defenses against a potential attacker breach.

What is Red Teaming?

Red teaming is a more general adversarial approach to security. Imagine that testers are professional specialists who act as the “bad guys” and simulate the complex continuous attack that your business is experiencing. They don't just try to find the vulnerabilities, they also test how well your team (the “blue team”) can detect and respond to the threats. So, the Red Team attacks to find weaknesses, unlike the Blue Team, which defends and repels attacks.

Red teams try to infiltrate a company's system unnoticed and remain undetected for as long as possible to gain more information. They typically involve social engineering tactics and physical security testing to make it thorough. It's an in-depth approach that helps in better understanding where its real weaknesses lie, so it can improve its resilience against complex cyber threats.

Pentesting vs. Red Team: Analysis of the Main Differences

Pentesting and Red teams are two different approaches to assessing the security of your business. In this section, we’ll explore differences of both, in relation to objectives, methodologies, outcomes etc.

1. Duration Difference

Red teaming is a long-term strategy, while pentest is a more immediate assessment. In penetration testing, the exercise focuses on specific systems or applications for a few days to a few weeks. This is in contrast to red teams, which are usually conducted over several weeks and months

2. Objectives Behind

Penetration testing aims to identify technical vulnerabilities within a defined scope, usually for compliance purposes. Pentest is used to verify compliance with security requirements, identify and fix flaws before they can be exploited by attackers. In contrast, red teams attempt to simulate attacks to assess the overall effectiveness of security, including the organization's ability to detect and respond to threats. The Red Team checks the effectiveness of the human factor, physical, technical safety, and access controls.

3. Tactics Employed

Pentesting has more standardized tactics, while red teams use a much wider range of methods and tools. Penetration testing uses more formalized methodologies, such as network scanning and vulnerability assessments, to target technical vulnerabilities. The test focuses on the technical aspects of security and includes mostly automated and manual tests. 

Red teams, on the other hand, include a wider range of approaches, including human attacks (phishing, vishing) and physical security testing to simulate complex multistep attack scenarios. It necessarily uses social engineering, but pentest can also include this method if it falls within the defined scope of the project.

4. Resource Requirements

In general, a penetration test consumes fewer resources: it can be performed in a shorter period of time and by a much smaller specialized pentesters team that requires mostly technical skills. A red team requires a larger, multidisciplinary team with more diverse skills that will work over a longer period of time. This approach requires not only technical but also organizational resources. 

5. Expected Results 

While penetration testing typically concludes with a report on the results of the pentest, on the vulnerabilities found, and steps to remediate them, red teaming goes a step further to provide advanced knowledge of the system's security posture and provides a broader assessment of the effectiveness of system security and the organization's ability to respond to incidents. Thus, pentesting focuses on identifying and fixing vulnerabilities, while red teams provide more data about the overall security posture.

6. Budget Considerations

Penetration testing is usually less costly due to shorter timeframes and fewer resources involved. Red teams are very efficient, but more costly because it requires more time, human, and technical resources.

How Do I Choose Between a Penetration Test and Red Teams?

Understanding the differences between these approaches will help you make the right choice and make a more informed cybersecurity decision. As such, penetration tests and red team engagements need to be carefully considered in order for an organization to achieve the desired result.

A penetration test is ideal for any business that needs to identify specific vulnerabilities within defined systems. It is indicated for those clients who need to obtain focused assessments and clear remediation roadmaps. Whether you have specific compliance requirements or just want to make sure that a particular application or network is secure, now is the time to consider a penetration test. 

A penetration test is a method of testing security in a short time frame when time constraints are a factor. This approach is often preferred when a cost-effective and resource-efficient pen testing option is desired. Typically, it is employed to assess the security of new systems and software upgrades. We advise integrating it into your regular security activities to facilitate the swift detection of potential issues related to access flaws.

On the other hand, red teaming is better suited for companies that need in-depth reviews of general security postures. This type is for those who want to practice how well they will respond to real-world attacks, including physical security threats. If you are interested in improving your organizational security policy and your incident response capabilities, if you want to know how attackers can exploit your security, then the red team is for you.

Conclusion

Both approaches are important. If you use red teaming and penetration testing in combination, it will help to provide more comprehensive protection and is the most effective strategy for the security of organizations. 

Datami experts recommend ordering a penetration testing service to assess the technical security of specific systems, and then opting for Red Teams to evaluate the effectiveness of the organization's defense and response to complex attacks.
