Penetration testing and Red teaming are two popular security testing techniques used to evaluate the security posture and defenses of a network. While they might sound similar, they serve distinct purposes in assessing and fortifying a company's security posture.
In this blog, we'll explore the nuances of each, their methodologies, differences from other security assessments, and ultimately, which approach might be the best fit for your business.
Understanding Penetration Testing
Penetration testing, often referred to as "pen testing," is a systematic approach to evaluating an organization's network, applications, or systems for vulnerabilities that malicious actors could exploit.
NIST defines it as 'A test methodology in which assessors, using all available documentation (e.g., system design, source code, manuals) and working under specific constraints, attempt to circumvent the security features of an information system.'
Penetration testers simulate real-world attack scenarios to exploit vulnerabilities in a network, application, or system to see how much access an attacker could potentially gain. They do this by probing the target system using a combination of automated and manual exploitation methods.
The primary objective of penetration testing is to identify potential weak points before attackers can exploit them. In addition to finding vulnerabilities and helping prevent attackers from exploiting them, pen testing can also be used to test your defenses and see how effective they are in real-world scenarios. When you have a better understanding of your security posture, you can take steps to improve it. Statistics show that 74% of organizations perform penetration tests for vulnerability management program support, 73% for measuring security posture, and 70% for compliance.
In comparison to a vulnerability scan, penetration tests provide a much more thorough assessment of your environment. It approaches your IT infrastructure from every possible angle, covering all the bases and looking for weaknesses in your systems and processes.
In essence, pen testing is a form of ethical hacking that simulates real-world attacks on your infrastructure to gaps in your security. It may not have other objectives such as demonstrating security controls and compliance with industry standards and usually doesn't take too long to complete. Let's look at red teaming next.
Understanding Red Team Exercises
Red Teaming goes beyond the scope of traditional penetration testing. It is a comprehensive assessment of an organization's overall security posture, including people, processes, and technology. Red Teaming aims to mimic the sophisticated tactics employed by advanced cyber adversaries, offering a holistic view of an organization's ability to detect and respond to targeted attacks.
Red Team assessments involve long-term engagements, during which the team continuously challenges the organization's security controls and response capabilities. They combine various attack vectors and use social engineering to infiltrate the company's infrastructure.
The primary objective of a Red Team exercise is to simulate a real-world attack to determine how strong an organization's defenses are against cyber attacks. It assesses the overall security readiness of an organization against threats that are specifically designed to circumvent the security controls in place.
Red Team Testing Methodology
Red Team Testing follows a structured process to assess an organization's security posture comprehensively. Your Red Team could be an in-house team or a third party hired as a consultant.
The methodology typically includes the following stages:
- Planning and Goal Setting: The Red Team collaborates with the organization to define objectives, scope, and rules of engagement.
- Reconnaissance: Gathering information about the target to identify potential vulnerabilities and weak points.
- Red Team Scenarios: Creating custom attacks tailored to the organization's environment and security infrastructure.
- Execution: Executing the planned attacks, which may include phishing emails, social engineering tactics, or exploiting software vulnerabilities.
- Exploitation: Gaining unauthorized access to systems and escalating privileges to assess the extent of potential damage.
- Post-Exploitation: Assessing the ability to maintain access without detection, exploring lateral movement within the network.
- Reporting: Providing a detailed report of findings, including recommendations for improving security measures.
Red team exercises are usually carried out over long periods of time compared to penetration tests and are more focused in scope and depth. The process may involve people and processes outside of the IT team as well since it is focused on how the organization as a whole responds to security incidents. A recent study showed that businesses that carried out red team testing exercises saved an average of $204k on the cost of a breach, making it a useful investment in the long term.
Red Team vs. Blue Team
In cybersecurity, the terms "Red Team" and "Blue Team" represent opposing forces: attackers and defenders, respectively.
Red Team: The Red Team is responsible for simulating cyber adversaries, attempting to breach the organization's defenses and exploit vulnerabilities. Their aim is to find weak points in the security measures.
Blue Team: The Blue Team, on the other hand, comprises the organization's defenders. They are responsible for detecting and responding to security incidents, safeguarding the system against attacks.
When you engage both red and blue teams in a co-operative manner, you can find weaknesses in your security measures and also find out how you can improve your security strategy and controls to prevent future attacks.

| Aspect | Red Teaming | Pen Testing |
|---|---|---|
| Aspect | Testing detection, response, and recovery capabilities | Identification of vulnerabilities and potential exploitation methodsand |
| Scope | Broad and holistic assessment of security posture including people, processes, and technology | Focused on specific vulnerabilities in network, systems, and applications |
| Duration | Long-term engagement (Weeks to months) | Short-term assessment (days to weeks) |
What's Right For My Business?
The decision between Penetration Testing and Red Teaming depends mainly on the maturity of your cybersecurity strategy and your organization's security posture. If your organization is relatively new to cybersecurity and/or lacks an active cybersecurity strategy, start with a vulnerability assessment. Red team exercises are usually meant for organizations that have a proper defense strategy in place and want to test its effectiveness using a more rigorous approach.
- Choose Penetration Testing If:
- You want a focused assessment of specific vulnerabilities.
- You have budget or time constraints for a more extensive test.
- You're just getting started with building your defense against threats.
- Choose Red Teaming If:
- You want a comprehensive evaluation of your entire security posture. You require a long-term engagement to test your detection and response capabilities.
- You want to understand your organization's resilience against advanced and persistent threats.
