What Is A Purple Team In Cybersecurity Operations?

You’ve probably heard people talking about red teams and blue teams. But have you heard about the purple team in cybersecurity operations? It’s actually the bridge that connects the two, and honestly, Cyber threats are evolving faster, so organizations need more than siloed teams working in isolation. They need collaboration, communication, and continuous improvement. That’s exactly what a purple team delivers.

In this blog, we’ll walk you through everything you need to know about purple teams. What they are, how they work, why they matter in 2026, and how you can build one that actually makes a difference.

What Exactly Is a Purple Team in Cybersecurity Operations?

Red teams act as attackers as they simulate threats to find weaknesses in your systems. Blue teams act as defenders as they monitor, detect, and respond to those threats. So, where does the purple team fit in?

A purple team is a collaborative function that combines the offensive skills of the red team with the defensive knowledge of the blue team. Rather than working separately and sharing results at the end of an exercise, purple teams work together. They share insights, test defenses immediately, and loop findings back into the security program without delay.

Furthermore, purple teaming is not just a one-time event. It’s an ongoing process that continuously improves your detection and response capabilities. As a result, organizations build stronger, smarter defenses over time.

How Does a Purple Team Actually Work?

Now that you understand the concept, let’s talk about the process. Purple teams are designed with a fairly structured, yet adaptable workflow. A typical workflow appears like this:

Step 1: Establish the objective

The team chooses the specific threat scenario they’d like to simulate. This might be a ransomware attack, an insider threat, or a supply chain compromise. These scenarios are derived from intelligence and organization-specific risk posture.

Step 2: Run the attack

Members of the red team execute the attack scenario, while the blue team detects it and actively monitors its progression. However, unlike a traditional red team exercise, both sides communicate throughout the process. The red team shares tactics, techniques, and procedures (TTPs) as they go. So the blue team can test whether their current tools and processes catch them.

Step 3: Analyze Detection Gaps

After each attack simulation, the team analyzes what the blue team caught and, more importantly, what they missed. After the attack is completed, the blue team, with insights from the red team, can identify any gaps in detection. They can then report on their findings and provide actionable suggestions to plug those detection gaps. 

Step 4: Update the defenses and retest

After the analysis is complete, the blue team can update its detection rules, playbooks, and alert thresholds to take into account the gap identified. The red team then repeats the same attack scenario and verifies if the measures in Step 3 actually worked. This cycle continues in perpetuity.

Step 5: Document and improve

At the end of each cycle, the purple team compiles a report which ties findings back to appropriate framework(s), such as MITRE ATT&CK.

Key Benefits of Running a Purple Team Program

So why should your organization invest in a purple team? The benefits are substantial and very tangible.

1. Improved Detection Capabilities: Because red and blue teams work side by side, the blue team understands attacker behavior. As a result, they write better detection rules and respond to alerts faster.
2. Stronger Communication Culture: Purple teaming breaks down the wall between offensive and defensive security. Therefore, your security teams develop a shared language and mutual respect that strengthens overall operations.
3. Continuous Security Validation: Unlike annual penetration tests, purple team exercises run continuously. This means you validate your defenses against the latest threats on an ongoing basis.
4. Alignment With Threat Intelligence: Purple teams actively incorporate current threat intelligence into their simulations. Consequently, you’re always testing against the threats that matter most to your industry right now.
5. Better Use of Security Tools: Many organizations invest heavily in SIEM platforms, EDR solutions, and threat intelligence feeds. But never fully validate whether these tools detect real attacks. Purple teams fix that gap directly.

Purple Team Tools You Should Know in 2026

The toolset for the purple team in cybersecurity operations has expanded significantly. Here are some of the most widely used platforms in 2026:

• MITRE ATT&CK Navigator: For mapping and tracking TTPs during exercises
• Atomic Red Team: A library of small, focused attack simulations aligned to ATT&CK
• Caldera: An automated adversary emulation platform developed by MITRE
• Vectr: A collaborative purple team management platform for tracking exercises and metrics
• Splunk or Microsoft Sentinel: As the detection layer, where blue teams validate their alert coverage

Common Mistakes to Avoid

Even experienced teams make mistakes when building purple team programs. Here are the biggest ones to watch out for:

1. Considering Purple Teaming As An Occasional Thing: This approach will not yield results, as purple teaming only works when done continuously.
2. Lack of Documentation: Without proper documentation, you cannot accumulate the required institutional knowledge.
3. Failing To Account For The Human Factor: Simply focusing on technology is insufficient; analyst training is also necessary.
4. Lack of Relevance: It’s much more beneficial to conduct an exercise focused on specific threats to your company than a generic one.

Conclusion

The purple team in cybersecurity operations is no longer a nice-to-have. It’s a must-have for any organization that’s serious about defending against modern threats in 2026. You dramatically improve your detection capabilities and close security gaps faster with this. So, whether you’re a CISO or a security analyst, now is the perfect time to start your purple team journey. 

Frequently Asked Questions

Is a purple team the same as a security team?

No. A purple team is not a separate security department. It is a way for red teams and blue teams to work together, share findings,s and improve defenses.

Do small businesses need purple team exercises?

Yes, especially if they handle sensitive data. Even simple purple team activities can help uncover security gaps and improve incident response before a real attack happens.
