Cybersecurity can feel like a complex maze, which is why security leaders must understand the difference between red teaming vs penetration testing. But it doesn’t have to be that way. As a cybersecurity leader, staying ahead of threats is within your reach. Numerous areas of preemptive testing can benefit your team.
Two common methods to assess your security are red teaming vs penetration testing. Both are valuable, but they serve different purposes. Here's a look into what red teaming vs penetration testing entails and how to determine which one best meets your needs.
What is red teaming?
Red teaming is like bringing in a group of highly skilled hackers to test your security, but with permission and under controlled conditions. This approach dates to military strategy in the Cold War when the U.S. Armed Forces used "red teams" to simulate enemy attacks and test their defenses. Today, red teaming involves simulating real-world threats to understand how well your security can respond.
Red teamers act like sophisticated adversaries, using a combination of technical and social engineering tactics to infiltrate your defenses. They can employ stealth, deception, and persistence to achieve their goals, which may range from stealing sensitive data to disrupting critical systems. This holistic approach provides a thorough test of your true security posture, offering insights into your resilience and ability to detect and respond to attacks.
Red teaming engagements can last several weeks and involve comprehensive attack simulations. The goal is to mimic realistic cyberthreats to challenge your people, processes, and technology by emulating the tactics, techniques, and procedures (TTPs) employed by malicious actors. This type of assessment can uncover systemic weaknesses that traditional security tests may overlook.
What is penetration testing?
Penetration testing, or pen testing, has a narrower focus. Think of it as a targeted probe into specific parts of your security infrastructure. Unlike red teaming, which replicates entire attack scenarios, pen testing aims to identify and exploit particular vulnerabilities in a defined scope, such as your IT infrastructure, applications, or network security controls.
Penetration testers use various tools and techniques to find and exploit vulnerabilities. They might conduct vulnerability scans, perform network sniffing, or develop exploits to test the security of specific components. Pen tests are generally shorter engagements, typically lasting one to two weeks. The results include detailed reports highlighting the vulnerabilities found and recommending steps for remediation.
Penetration testing is often required for compliance with industry regulations like HIPAA, PCI DSS, or GDPR. It's also a useful way to address specific security concerns, especially for smaller organizations, or those with limited security resources. While pen testing doesn't simulate full-scale attacks like red teaming, it provides valuable insights into specific vulnerabilities and how to fix them.
What is a red team assessment?
A red team assessment is an immersive cybersecurity exercise designed to evaluate your security posture by simulating cyberattacks. Unlike traditional penetration tests, red team assessments take a comprehensive approach, testing your organization against sophisticated adversaries.
During a red team assessment, experienced cybersecurity professionals, the red teamers, assume the role of malicious actors, employing a wide range of TTPs to infiltrate your defenses and achieve predetermined objectives. The red team engineers work to challenge normal testing procedures and find unexpected vulnerabilities in policies, procedures, systems, and people. These objectives may include gaining unauthorized access to sensitive systems or data, escalating privileges, or disrupting critical operations.
Here are various aspects of red team assessments.
Holistic attack simulation
Red team assessments mimic actual cyberthreats, encompassing a diverse array of attack vectors and scenarios. From social engineering and phishing attacks to advanced persistent threats (APTs) and insider threats, red teamers employ a multi-faceted approach to emulate the tactics used by actual adversaries.
Objective-Driven approach
Red team assessments are conducted with specific objectives in mind, tailored to your unique security challenges and priorities. By defining clear objectives at the outset of the assessment, you can focus on evaluating critical aspects of your security defenses and incident response capabilities.
Stealth and deception
Red teamers leverage stealth, deception, and evasion techniques to bypass security controls and remain undetected within the target environment. Red team assessments provide valuable insights into your ability to detect and respond to advanced threats by mimicking tactics commonly used among sophisticated attackers.
Comprehensive reporting and recommendations
Following the assessment, red teamers provide detailed reports outlining their findings, including successful attack paths, vulnerabilities exploited, and areas for improvement. These reports often include actionable recommendations for enhancing security controls, mitigating risks, and strengthening overall resilience.

Identifying red teaming vs. penetration testing
While both red teaming and penetration testing are essential components of a comprehensive cybersecurity strategy, they differ in several key ways, including:
- Scope and objectives: Red teaming has a broader scope, simulating a full-scale attack across your organization, while penetration testing targets specific vulnerabilities within a defined scope. Red team assessments are goal-oriented, focusing on testing your overall security posture, while pen testing aims to identify and remediate specific weaknesses.
- Methodology: Red teamers use numerous techniques, including social engineering, physical penetration, and APTs, to mimic attacks. They operate covertly, using stealth and deception to avoid detection. Pen testers rely on automated tools and scripted processes to find and exploit vulnerabilities within the scope of their assessment.
- Engagement length: Red team engagements typically run for four to six weeks, providing a thorough examination of your security defenses. Pen tests are shorter, usually one to two weeks, and focus on identifying specific vulnerabilities.
- Reporting and recommendations: Red team assessments offer in-depth reports detailing the entire attack lifecycle, along with recommendations for improving your security posture. Pen tests provide more targeted reports with specific vulnerabilities and suggestions for fixing them.
When to use red teaming vs. penetration testing
Choosing between red teaming and penetration testing depends on your organization's unique needs, security maturity, and risk tolerance. Considerations to help you decide include:
-
Red teaming: This approach is ideal for complex environments with diverse systems and high-risk industries like finance, healthcare, or government. If you're looking for a comprehensive test of your security posture and want to evaluate your resilience against sophisticated threats, red teaming is the best choice. It's also suitable for mature security infrastructures that require a thorough examination to uncover systemic weaknesses.
- Penetration testing: This option is best for more targeted assessments or when compliance requirements must be met. Penetration testing is also appropriate for smaller organizations or those with limited resources. It's an effective way to identify specific vulnerabilities and validate security controls without the broader scope of red teaming.
Vulnerability scanning vs. red teaming
It's essential to distinguish between vulnerability scanning and red teaming. Vulnerability scanning involves automated tools that scan for known security flaws, misconfigurations, and weaknesses in your network, systems, or applications. It provides a snapshot of potential risks and helps prioritize remediation efforts.
In contrast, red teaming goes beyond vulnerability scanning by simulating attack scenarios. It incorporates a mix of technical and social engineering tactics to assess your security posture. While vulnerability scanning is a valuable baseline for identifying security flaws, red teaming offers a more in-depth approach uncovering systemic weaknesses and test your defenses against sophisticated threats.
Combining red teaming and penetration testing
In many cases, the best approach to cybersecurity is a combination of red teaming and penetration testing. Pen testing helps identify and address specific vulnerabilities, while red teaming provides a comprehensive assessment of your overall security resilience.
Consider starting with penetration testing to identify immediate vulnerabilities and compliance requirements. Then, follow up with red teaming to simulate threats and test your security posture. This approach allows you to build a robust security strategy that can adapt to evolving cyberthreats.
Keep testing to build your defense
Red teaming and penetration testing are both critical tools in your cybersecurity arsenal. Each serves a unique purpose, and choosing the right one depends on your goals and risk profile. By understanding the differences and knowing when to use each method, you can create a security strategy that keeps your organization safe in a shifting threat landscape.
