Organizations test their level of security in various ways. Two approaches that sometimes get confused are penetration testing and red teaming. Both involve simulating attacks to find weaknesses, but they do it in different ways and with different goals. Here’s how each works and where each is most suitable.
Penetration testing
In penetration testing, the goal is to see where hackers might sneak in and fix any weak spots before they become a problem. Pentesters focus on specific areas such as networks, applications, or devices, using tools and techniques that mimic attacks. Cycognito has summed it up neatly: pentesting is a simulated attack on a system, network, or application to identify vulnerabilities.
Certain tools make the process easier and can automate reporting and project management. For example, Cyver’s pentest reporting tool makes it easy for organizations to see any vulnerabilities clearly, turning technical details into steps that security teams can act on.
Businesses must conduct regular security tests, including pentesting, to comply with regulations like GDPR and HIPAA. This has led to pentesting becoming a huge industry, which was predicted to exceed $7.1 billion by 2032 .
Red teaming
Red teaming looks at security through a wider lens. Instead of checking individual systems, it tests how well the entire organization can handle an attack. The term “red team” was formalized during the Cold War when military and intelligence agencies’ units acted as enemies in war games. Red teams work over more extended periods, sometimes weeks or months, to get a realistic view of security in action.
Key differences in scope and objectives
The main difference comes down to focus. Penetration testing is usually narrow and time-limited, concentrating on certain systems or applications. Red teaming is broader, assessing the organization’s entire defenses. Penetration testing reports show exactly what is vulnerable and how to fix it; red team reports show how well teams respond to threats and where processes might need improvement.
In short, pentesting is about finding weak spots; red teaming is about testing your ability to respond to them.
Methods used in penetration testing
Pentesters start by gathering information; they then scan for weaknesses, exploit vulnerabilities, and report their findings. They might target outdated software, misconfigurations, or weak passwords, using a mix of automated tools and manual techniques to cover all angles.
Methods used in red teaming
Red teams often send convincing phishing emails, try to sneak into physical spaces, or use malware to see what they can access. Despite security teams knowing about the dangers for decades, phishing attacks are still a major concern. Harvard University, for example, recently reported that personal information of students, doctors, and faculty members was exposed.
Red teaming is sometimes referred to as ethical hacking, because the team members actually exploit vulnerabilities in their testing, rather than merely provide a theoretical report. The methods used are extensive, and involve physical testing where teams try to stroll past controls without security noticing, and intercepting communication where they hack internal emails, texts, and phone calls.
When to use penetration testing versus red teaming
Penetration testing is useful for identifying and fixing specific vulnerabilities, whether for regulatory compliance or routine system checks. Red teaming is more about testing overall resilience against complicated attacks. Organizations benefit from using both: pentests for technical hardening and red teaming for testing response readiness.
Pentest results can guide red team exercises, and red team findings can point to areas needing deeper testing. Using both pentesters and red teams helps organizations stay ahead of threats, improve their processes, and build confidence in their defenses. The goal is to create an up-to-date, security-aware culture that can handle whatever comes next.
