Red Teaming vs. Purple Teaming: Which One Does Your Organization Really Need?

In the ongoing battle against cyber threats, most organizations agree on one thing: testing your defenses isn’t optional anymore. But how you test them matters. That’s where the conversation around Red Teaming and Purple Teaming begins.

At Resilience, we’ve worked with clients across Saudi Arabia who ask the same question:
“Should we start with Red Teaming, or do we need Purple Teaming?”

To answer this question, let’s break it down, because the difference isn’t just about color. It’s about purpose, collaboration, and outcomes.

Red Teaming?

Red Teaming is an attack simulation where an external team (the “Red Team”) plays the role of a real-world adversary. The goal is to test how well your people, processes, and technology can detect and respond to advanced threats, without any prior warning.

Example Scenario: In one FEER aligned engagement with a financial institution, our Red Team exploited a vulnerable SharePoint server (T1190) to gain initial access, moved laterally using RDP (T1021.001), dumped credentials from LSASS (T1003.001), and exfiltrated data over HTTPS (T1041) all without triggering any alerts.
Goal: Realism. Surprise. Executive-level insight into readiness.

Purple Teaming?

Purple Teaming isn’t a test, it’s a collaborative exercise.
In a Purple Team engagement, the Red and Blue Teams work together to simulate attacks and immediately assess how well defenses hold up. It’s more of a hands-on, educational process.

Example Scenario: During a Purple Team workshop with a national utility provider, the Red Team simulated credential access (T1555.003 – AWS credentials), while the Blue Team tuned and tested cloud monitoring tools to detect access anomalies. Within hours, detection time dropped from 22 minutes to under 2 minutes.
Goal: Shared learning. Detection tuning. Faster improvement cycles.

Key Differences at a glance

When to use each approach?

Use Red Teaming when:

– You want to simulate a stealthy APT attack.
– You’ve already covered the basics and need realism.
– You’re preparing for regulatory exercises like SAMA’s FEER.

Use Purple Teaming when:

– You’re building or maturing your detection program.
– You want to validate and improve coverage in MITRE ATT&CK.
– Your Blue Team is ready to learn, test, and evolve.

Purple Teaming in Saudi Arabia: Growing Need

As frameworks and methodologies like SAMA’s FEER, NCA ECC, and MITRE ATT&CK become standards in Saudi Arabia, more organizations are turning to Purple Teaming to operationalize detection and threat hunting.

It helps teams:

– Tune SIEM and EDR rules against real-world TTPs
– Practice incident response in a safe environment
– Align their SOC operations with regulatory frameworks

In regulated sectors, it’s becoming a must-have—not a nice-to-have.

How Resilience Delivers Both

At Resilience, we offer:

– Red Teaming engagements aligned SAMA’s FEER and the MITRE ATT&CK
– Purple Teaming programs that empower SOC teams to build detection muscle
– Real-world attack simulations tailored to local threats in the GCC
– Continuous improvement and actionable reporting for CISOs and boards

We don’t just test. We teach, tune, and build resilience that lasts.
