Red teaming is a proactive and holistic approach to assessing an organization’s cyber defenses. With this strategy, ethical hackers think like malicious attackers to simulate real-world attacks against an organization. Their goal is to expose and mitigate any vulnerabilities before actual attackers can exploit them. 

While red teaming is an effective tactic, it requires time and resources, and it’s crucial for any organization investing in red teaming assessments to measure the results of each test. 

Not only does this ensure the organization maximizes its resources, but it also quantifies the value of consistent red teaming. 

In fact, measuring success is just as important as running the test itself. In this guide, we’ll explore the key ways to evaluate a red teaming assessment, ensuring your business gets actionable insights instead of just another report collecting dust.

Why Should Businesses Measure Red Teaming Results?

Most red teaming exercises reveal gaps that need to be addressed. While that alone is valuable, organizations must also ensure that their red team assessments deliver actionable improvements. 

Businesses should measure the effectiveness of red teaming to:

• Validate improvements: Red teaming identifies vulnerabilities, but without measurement, there’s no way to track whether your team has effectively mitigated them. Monitoring improvements in security metrics tells you whether defenses have actually improved over time. 
• Understand response effectiveness: Tracking red teaming results measures how well your security team detects and neutralizes threats during an attack. Key performance indicators (KPIs) like time to detect (TTD), time to respond (TTR), and time to remediate (TTRM) provide helpful insights into operational readiness.
• Measure employee awareness: While red teaming assessments measure the effectiveness of the red team itself, they also look at employees’ understanding of malicious threats. Social engineering tests, in particular, reveal how well employees follow security protocols. 
• Quantify business impact: Nothing shows stakeholders the value of red teaming as much as quantified impacts. Security risks can lead to data breaches, reputational damage, and regulatory fines. Measuring red teaming outcomes in dollar signs helps businesses understand the potential cost savings of preventing real-world attacks.

3 Tips for Measuring the Effectiveness of a Red Teaming Assessment

So, how do you know if a red teaming assessment is valuable? Follow these best practices to accurately measure the impact of red teaming on your organization. 

Set Actionable Goals

While many red teams use similar exploits to test organizational defenses, every business is different. You can’t understand the value of a red teaming assessment without a goal to measure it against. 

Establish specific goals for the red teaming assessment, such as testing cybersecurity defenses, physical security, or employee awareness. That will make it easier to review results after the test and better understand if the assessment delivered value. 

Track The Right Metrics

The easiest way to understand the effectiveness of red teaming is to monitor changes in security metrics like: 

• Time to detection: This metric tracks how long the defensive team takes to detect a simulated attack. Reductions in detection time mean you have a more effective team. 
• Time to respond: Evaluate how quickly your team contains and neutralizes threats after they detect them. If there are delays in response times, that indicates you need to improve incident response. 
• Exploitation success rate: Test how employees react to phishing emails, social engineering, and unauthorized access attempts. Effective red teaming should help reduce the success rate of these attacks. 

Quantify The Impact

Business economic impact is one of the most effective ways to measure the effectiveness of red teaming. Assess how the simulated attack affected business continuity, company finances, and system downtime in terms of dollars. 

Understanding and sharing these costs will also help stakeholders support future investments in security. 

Measuring Red Teaming Success in Generative AI Security

As generative AI systems become increasingly integrated into business operations, their security vulnerabilities present unique challenges. Red teaming assessments are critical for identifying and mitigating these vulnerabilities, but measuring their effectiveness requires a tailored approach. 

Define Generative AI-Specific Objectives

Generative AI systems, such as large language models (LLMs) or AI-driven content creation tools, have distinct attack surfaces posing unique risks such as prompt injection, data poisoning, and model extraction, among others. To measure the effectiveness of a red teaming assessment, organizations must first establish clear, generative AI-specific goals. These might include: 

• Testing the resilience of AI models against adversarial inputs. 
• Evaluating the effectiveness of safeguards against misuse (e.g., generating harmful content). 
• Assessing the security of the data pipelines feeding into the AI system. 
  

Setting relevant objectives helps to ensure that red teaming exercises are aligned with the unique risks posed by generative AI. 

Track Generative AI-Specific Metrics

Traditional security metrics like TTD and TTR remain relevant, but additional metrics are needed to address generative AI-specific threats. 

The table below shows some of the key metrics to track. These metrics provide a clearer picture of how well the generative AI system is protected against emerging threats.

Quantify the Business Impact of Generative AI Vulnerabilities

Generative AI systems often play a critical role in business operations, from customer service to content creation. A successful red teaming assessment should quantify the potential business impact of vulnerabilities specific to these systems,  such as:

• Reputational damage: Estimate the cost of a generative AI system producing harmful or biased content that goes viral. 
• Operational downtime: Calculate the financial impact of a compromised AI system disrupting business operations. 
• Regulatory fines: Assess potential penalties for failing to comply with regulations such as data privacy laws or ethical AI use.  
  

Translating vulnerabilities into financial terms can help organizations justify investments in generative AI security. 

Evaluate Employee and System Preparedness

Generative AI systems often require human oversight to function effectively. Red teaming assessments should evaluate both the technical and human elements of AI security. Some key questions to answer include: 

• How well do employees recognize and respond to attempts to misuse or exploit generative AI systems? 
• How effective are monitoring tools in detecting anomalous behavior or outputs from the AI system? 
• How fast and efficient is the response team in addressing AI-specific threats, such as prompt injection attacks? 

Continuously Iterate and Improve

Generative AI is a rapidly growing field, and so are its associated threats. Measuring the effectiveness of a red teaming assessment should not be a one-time activity.

Instead, leverage red teaming tools such as continuous automated red teaming (CART) to conduct regular red teaming assessments and stay ahead of new attack vectors. 

Use the insights gained from each assessment to refine AI security policies and procedures, and continuously update training programs to ensure employees are aware of the latest threats. 

Real Security Never Sleeps

Red teaming is a smart addition to any cyber security strategy, but organizations still need to understand its value. Tracking performance and key metrics will help your company assess its defense capabilities and overall preparedness against threats. 

A successful red teaming assessment goes beyond identifying weaknesses—it provides a clear roadmap for mitigation, enhances collaboration between security teams, and aligns security strategies with industry standards and business objectives.

Frequently Asked Questions

Can red teaming expose weaknesses that a regular security audit might miss?

Absolutely. Unlike standard security audits that check for basic best practices, red teams think like an attacker. They find creative, unexpected ways to exploit people, processes, and technology. 

How do you measure success if the red team ‘fails’ to breach security?

If the red team doesn’t succeed in breaking in, that’s great news, but it doesn’t tell the whole story. Success isn’t just about finding gaps; it’s also about testing response times, employee reactions, and overall preparedness. 

Even if the team doesn’t find major vulnerabilities, businesses should still analyze how well their teams reacted to the simulation.

What’s the biggest mistake companies make after a red teaming assessment?

Security isn’t a one-time fix—it’s an ongoing process. One of the biggest mistakes is treating the results as a checklist instead of a strategy. Red team assessments become expensive, unhelpful exercises if companies fail to prioritize, address, and monitor threats.
