The Difference Between Pentesting and Red Teaming

The terms penetration testing and red teaming are frequently mentioned in the world of cybersecurity. Though, they’re not always clearly differentiated. While both play their own important roles in strengthening an organization’s security posture, they employ distinct methodologies and objectives. In fact, sometimes they’re used together.

This article looks into the differences between penetration testing and red teaming. By understanding these differences, organizations can better tailor their cybersecurity strategies to protect against the outside threats.

The Difference Between Pentesting and Red Teaming

Understanding Penetration Testing

Penetration testing, commonly referred to as “pentesting”, is a cybersecurity technique focused on identifying and exploiting vulnerabilities. These vulnerabilities lie within an organization’s systems and networks. 

Essentially, pentesting simulates an attacker’s attempt to penetrate the digital infrastructure, but with the intent to uncover and address security weaknesses rather than to harm. This is a bit like putting yourself in the shoes of a bad actor, to really analyse, in a practical way, your own weaknesses.

Penetration testers use a variety of tools and techniques to scan for vulnerabilities, such as outdated software or flawed security protocols. 

They then attempt to exploit these vulnerabilities, mimicking the actions of potential attackers. This process is not about discovering unknown vulnerabilities, but rather focuses on identifying and exploiting known issues that haven’t been patched or mitigated​.

Of course, pentesting isn’t always easy to do yourself because it’s easy to be blind-sided or unequipped. Therefore, outsourcing is the common option.

Exploring Red Teaming

Red teaming transcends the boundaries of traditional penetration testing by incorporating a more comprehensive and scenario-driven approach. It involves simulating real-world cyberattacks to test not just the technical defences, but also the human and procedural elements of an organization’s security. It’s essentially a step up from pentesting.

Red team exercises are designed to mirror the tactics and techniques of advanced adversaries. They involve a series of coordinated attacks against a variety of targets within the organization, including physical security, employee awareness and system vulnerabilities. It’s all-in on the role playing front.

The primary goal of red teaming is to evaluate the effectiveness of the entire security posture of an organization, often involving the exploitation of interconnected vulnerabilities across different systems and departments. By leaving no stone unturned, a red teaming exercise can paint a bigger and better picture of an organization’s defence.

All in all, it’s a way to assess how well the security operations center (SOC), or the ‘blue team’, can detect, respond to, and mitigate sophisticated and multi-faceted threats​.

Key Differences Between Penetration Testing and Red Teaming

While both penetration testing and red teaming aim to enhance cybersecurity, they differ in a few different aspects:

Goals and Objectives

Penetration testing is designed to find as many vulnerabilities as possible within a system and assess their risk. Red teaming, on the other hand, seeks to emulate a real-world attacker by finding and exploiting a single vulnerability to understand its potential impact on the entire system​. In this sense, red teaming is more practical, while pentesting is more theoretical.

Scope and Depth

Penetration testing typically has a narrower scope, focusing on specific systems or applications. Red teaming, conversely, adopts a broader approach, evaluating the organization’s overall security resilience, including human and procedural elements.

Methodologies and Techniques

Penetration testing employs systematic vulnerability scanning and exploitation. Red teaming uses advanced, real-world simulation techniques that may include social engineering and physical security tests​. Again, it’s even more practical and empirical.

Duration and Stealth

Penetration tests are generally shorter and less concerned with stealth. Red team operations aim for a higher level of discretion, often mimicking an Advanced Persistent Threat (APT) to remain undetected for longer periods​.


Because red teaming is even more extensive and hands-on, it is generally more expensive than a pentest project. The price may or may not be much different depending on the company, along with the scope and duration of the service. Pentesting is more likely to be done in-house, though both are commonly outsourced.

Practical Applications and When to Use Each

The choice between penetration testing and red teaming depends on the specific needs and maturity of an organization’s security posture, along with their time and budget:

  • Penetration Testing: Ideal for organizations seeking to identify and patch known vulnerabilities in their systems. It’s particularly useful for routine security assessments, compliance checks. Or, after implementing new systems.
  • Red Teaming: More suited for organizations with a mature security posture looking to test their readiness against sophisticated and multi-layered threats. It’s beneficial for assessing the effectiveness of security protocols and employee awareness.


Penetration testing and red teaming are complementary approaches to cybersecurity, each with its unique strengths and applications. While they are inherently different, they can be used together in some circumstances.

Deciding which approach to employ should be based on the organization’s specific security goals and resources. As cybersecurity threats continue to evolve, incorporating both methods into a robust security strategy can offer a more complete defense against potential breaches.
