Cyber threats are continually changing. So, traditional security testing is no longer enough for organisations. As attackers continually refine their techniques, security teams need to respond quickly to increase their defenses. Thus, this has led many companies to use purple teaming both to help encourage everyone to collaborate on an offensive/defensive team and to introduce the purple teaming best practices to ensure overall security effectiveness.
In addition, it takes more than rudimentary testing to be successful with purple teaming. Teams must be well planned, well communicated, and have realistic objectives for effective outcomes. That’s why today’s organizations need to understand purple teaming best practices.

Why Purple Teaming Best Practices Matter
A lot of money is spent on security solutions by organizations. But tools are a step that can be taken, but they will not prevent modern cyber threats. Attacks are always looking for system, process, and employee vulnerabilities. So, any organisation should have realistic testing to reveal vulnerabilities before attackers can take advantage of them.
These are some of the great advantages of getting a video editor:
- Faster threat detection
- Better team collaboration
- Improved response capabilities
- The visibility of the system is improved
- A more realistic security test is achieved
Furthermore, organizations get insight into the actual attack behavior of attackers. This information assists teams in proactively strengthening their defense.
According to the Verizon Data Breach Investigations Report (DBIR 2024), around 68% of breaches involve the human element, such as phishing or social engineering.
Encourage Open Communication Between Teams
Communication skills have been one of the most important purple teaming best practices in today’s cybersecurity landscape. However, many organisations continue to have a hard separation of red and blue teams as is! This separation poses superfluous impediments. Defenders are therefore losing out on crucial information to help them better detect and defend.
Experienced purple teams say it’s time to encourage:
- Real-time collaboration
- Shared reporting
- Open discussions
- Immediate feedback
- Joint problem-solving
Plus, frequent communication enables teams to discover weaknesses far more quickly. Defenders can tweak monitoring strategies on the spot, and attackers can describe how they got past the defenses. Thus, security enhancement projects that involve collaboration will exhibit more accelerated enhancement progress as both parties study and learn from one another during the engagement.
Use Realistic Attack Simulations
Numerous inexperienced teams like to play it safe with unrealistic attacking situations. Security testing should, however, represent the real threats that the organisation is facing. Hence, this is one of the most practical purple teaming best practices, as realistic simulations give solid insights for the defense. Furthermore, many companies emphasize the testing of phishing attacks and credential theft, insider threats, ransomware scenarios, cloud misconfigurations, or privilege escalation techniques.
Moreover, teams have to make use of the threat intelligence available to them to create effective attack plans. In addition, this enables businesses to train on actual incidents rather than hypothetical scenarios. Therefore, seasoned security experts are aware that practical exercises provide greater security benefits than elaborate displays. Finally, having applied the best practices in purple teaming to realistic simulations, detection and response are significantly enhanced.
Real Life Example:
The Colonial Pipeline ransomware attack (2021) disrupted fuel supply across the U.S. after attackers used compromised credentials to gain network access.
Continuously Improve Detection Capabilities
The detection engineering is an important piece of the security puzzle in an effective response. Hence, alerts, monitoring rules, and visibility strategies should be continually evolved throughout the purple team. So, alerts, monitoring rules, and visibility strategies should be continuously updated throughout the purple team.
It is an important component of purple teaming best practices, as attackers are often updating their techniques.
Security teams should:
- Review missed alerts
- Analyze detection failures
- Improve SIEM rules
- Validate endpoint visibility
- Reduce false positives
Also, there should be tests to see if monitoring tools are able to accurately detect attacker action. Organizations need to address the gaps in systems right away if there are no indications of malicious activity. Thus, the teams are able to evolve their approach to threats over time, as they strive for continuous improvement.
Document Every Finding Carefully
Properly documented exercises can be the key to long-term value for purple team exercises. Unfortunately, some organizations take no more than to report once the engagement is over.
In addition, experts know that reporting can be a way to help future enhancements. As a result, documentation is still one of the most valuable purple teaming best practices of which organizations should avail themselves of.
Reports should include:
- Attack techniques used
- Detection performance
- Response timelines
- Security gaps identified
- Recommended fixes
- Lessons learned
Furthermore, technical and management teams should be able to easily read reports created by organizations. Good communication is essential to the effective support of future security improvements by leadership. Thus, it is also important to have good documentation so organisations can see progress at subsequent exercises.
Invest in Continuous Skill Development
Cybersecurity evolves rapidly. So, it is important for the organization to continuously train both teams to ensure that they have a robust security operation. Another key aspect of purple team best practices is continuous education; while the tools are important, experienced analysts are more beneficial.
Ways to invest:
- Hands-on labs
- Simulation exercises
- Threat hunting practice
- Incident response drills
- Technical workshops
- Industry certifications
In addition, there are regularly advanced teams who consult and review new attack methods and defensive technologies. Thus, such a practice helps organizations stay ahead of the curve when it comes to threats. So, a lot of technical skills make a big difference in all facets of purple teaming.

Built Long-Term Security Improvement Plans
Many organizations often treat purple teaming as a one-off exercise. However, effective security programs require continuous assessment and improvement. Thus, this is one of the least-used purple teaming best practices, as consistency over time builds resilience.
Organizations should: Following each engagement:
- Fix identified weaknesses
- Retest corrected systems
- Update security policies
- Improve response playbooks
- Schedule future exercises
Also, leadership needs to be engaged in monitoring security progress continually, rather than on specific achievements. Thus, continuous improvement is often a key hallmark of organizations more likely to be able to build up their defenses against new cyber threats.
Conclusion
By working together, combining different perspectives, and leveraging realistic testing and continuous improvement, purple teaming can help organizations make significant strides in enhancing their cybersecurity. Thus, once teams follow the best practices of purple teaming, they can be more effective in detecting threats, enhancing response measures, and minimizing security vulnerabilities.
Furthermore, a learning team can produce greater results than one that is competitive. There are ample opportunities to strengthen and improve security operations over time with the use of appropriate planning, communication, and purple teaming best practices.
