Penetration Testing vs. Red Teaming—What’s the Difference?

Author: Matt Hulse

Penetration Testing and Red Teaming are two critical aspects of cybersecurity testing. Although they might seem similar, they serve different purposes and therefore require unique approaches. This article dives into these distinctions, providing insights to help you incorporate both strategies into your organization’s cybersecurity testing program.


The need for cybersecurity testing services like Penetration Tests and Red Teaming is on the rise. Initially valued at $1.62 billion in 2021, the global Penetration Testing market is expected to grow at a CAGR of 13.9% over the next seven years, eventually reaching $4.84 billion by 2030. There are multiple factors driving this trend, including an uptick in ransomware attacks; the ever-shifting regulatory landscape; and the rising popularity of IoT, smartphone adoption, and cloud-based services.


What Are Penetration Testing and Red Teaming?

Penetration Testing, or “Pen Testing,” involves simulated cyber attacks on a computer system to identify vulnerabilities that real attackers might exploit.There are two main types of Penetration Tests:
1. Manual Penetration Testing: Security experts with specialized experience in Penetration Testing actively explore your systems, software, and hardware to detect vulnerabilities, and then exploit those vulnerabilities to demonstrate the risk.
2. Automated Penetration Testing: Using a toolset of largely automated scanning and exploitation frameworks, these software tools scan your environment for common vulnerabilities, such as missing or frequently used passwords. Automated Penetration Testing is a good strategy to incorporate into CI/CD environments to rapidly and automatically test software as part of the deployment lifecycle.

Penetration Testing vs. Red Teaming

By contrast, Red Teaming takes a broader perspective. While Penetration Testing focuses on breaking into specific systems, Red Teaming simulates a full-spectrum attack on your organization. It’s a realistic stress test that considers the human factor, organizational behaviors, physical security, and more. Red Teamers look at potential business impact rather than merely breaching the system.

4 Key Differences Between Penetration Testing and Red Teaming

Objective: Penetration Testing aims to find and exploit vulnerabilities within specific systems, whereas Red Teaming assesses overall security, including human elements and business impact.
Scope: Penetration Testing usually has a defined scope, focusing on technical vulnerabilities. Red Teaming, on the other hand, evaluates broader aspects of the organization, sometimes using non-technical means.
Methodology: Pen Testing can be manual or automated and typically follows a set pattern. Red Teaming is more flexible, often employing unconventional methods to simulate real-world threats.
Outcome: The success of a Pen Test is measured by the vulnerabilities uncovered and exploited. Red Teaming measures success by the broader understanding of organizational risk and potential business impact.
