Purple teaming

Your tooling is only as good as what it actually catches. Purple teaming works alongside your SOC to simulate real attacker behaviour. It measures exactly where your defences stop, and why.

You can invest in every tool on the market and still miss the attack that matters.

Purple teaming is a collaborative security exercise in which the Swarm simulates real attacker behaviour alongside your security operations team. Unlike a red team engagement where the SOC is unaware, both sides work in the open. The goal is not to catch your defenders out. It is to find and fix exactly where detection fails.

Most organisations invest heavily in security tooling and assume that investment translates into visibility. It often does not. Gaps in configuration, coverage, and alert quality can allow real attacker behaviour to pass unnoticed or leave analysts without the clarity to respond.

Tooling is not the same as visibility.

Most detection gaps are not caused by missing technology. They are caused by technology that was never configured to detect the behaviour an attacker would actually use.

A lone figure walking through a long illuminated corridor, a motion sensor above them glowing green, the alert never coming.

Every technique gets a verdict.

Every technique the Swarm executes is mapped to MITRE ATT&CK and assessed against a defined detection outcome. Progress is measurable, not assumed.

The gap closes during the engagement.

Purple teaming does not produce a report you action later. Detection rules are tuned and validated in real time, during the exercise itself.

Your detection capability is what we test.

Real attackers do not announce themselves. They operate quietly, map what they can reach, and move when they are confident nothing is watching. Purple teaming measures whether your SOC would know.

Atomic purple team

Individual attacker techniques executed in isolation to confirm what your tooling logs, what alerts fire, and where your detection fundamentals need work. The right starting point for any organisation building out SOC detection capability or validating coverage after changes to security controls.

APT scenario-based

Realistic multi-stage attack chains modelled on adversary behaviour relevant to your sector and risk profile. Tests whether your detection coverage holds up against a full sequence, not just individual techniques.

Objective-based

Defined attacker objectives are tested against critical systems under realistic conditions. This measures whether your SOC can detect, investigate, and disrupt a targeted attack as it progresses, rather than simply recognise the individual techniques involved.

Red team follow-up

Replay techniques from a previous red team engagement that were not detected or were only partially detected, using realistic red team timing and execution. The exercise validates whether remediation has improved detection coverage and identifies where further tuning or configuration changes are required, with findings reviewed collaboratively with your SOC at the end of the engagement.

Detection engineering support

Depending on the collaboration model chosen, the Swarm works directly with your SOC to review, refine, and validate detection rules during the engagement. The output is working detection logic, not just recommendations to action later.

Post-engagement tuning review

After every engagement, findings are mapped to specific MITRE ATT&CK techniques with tuning recommendations for your SIEM and EDR. Your SOC receives the context needed to action improvements and measure detection coverage over time.

We know that real attack surfaces don’t come in neat categories. If yours doesn’t fit above, tell us what you’re working with.

What a Purple Teaming Finding Looks Like

Finding

The Swarm executed a credential access technique mapped to MITRE ATT&CK T1003 against an agreed endpoint. The technique completed without triggering an alert. Telemetry confirmed the event was logged by the EDR but the detection rule had never been tuned to recognise the specific behavioural pattern used.

Impact

A real attacker using the same technique would have obtained credential material without triggering an alert. The SOC had no visibility of the activity despite the telemetry being present. The detection gap had existed undetected across the full lifetime of the tooling deployment.

Remediation

Tune the EDR detection rule to recognise the specific behavioural pattern observed during the engagement. Validate the updated rule by replaying the technique post-remediation. Conduct a full audit of detection rules against the MITRE ATT&CK techniques most relevant to your sector and threat profile.

Frequently asked questions

What is purple teaming?

Purple teaming is a collaborative security exercise in which the Swarm simulates real attacker behaviour while working openly alongside your security operations team. Unlike a red team engagement where the SOC is unaware, both sides work together. The goal is not to catch your defenders out but to find and fix exactly where detection fails.

How is purple teaming different from a red team engagement?

In a red team engagement the SOC and incident response team are not aware of the activity. The red team attempts to achieve objectives without being detected, simulating a real adversary. Purple teaming is the opposite. Both teams work openly and collaboratively. The goal is not to test whether the SOC can catch an attack in progress but to identify exactly where detection gaps exist and fix them during the exercise.

How is this different from a Breach and Attack Simulation tool?

BAS tools automate technique execution and score detection results. They are fast, repeatable, and useful for validating known detection rules at volume. Purple teaming with CovertSwarm is different. A specialist team executes techniques with the judgement, creativity, and adversarial thinking that automated tools cannot replicate. The output is not a score. It is specific, actionable detection engineering guidance validated by human operators who can adapt to what they find in your environment.

What are the different types of purple team engagement?

We offer four confirmed engagement types. Atomic exercises test individual techniques in isolation and are the right starting point for organisations building out SOC detection. APT scenario-based exercises test realistic multi-stage attack chains. Objective-based exercises measure whether your SOC can identify and disrupt an attack in progress. Red team follow-up exercises replay techniques from a previous red team engagement to validate whether remediation worked.

What do we receive at the end?

Every technique executed is assessed against a defined detection outcome. You receive a technique-by-technique findings report mapping detection gaps to specific MITRE ATT&CK techniques, SIEM and EDR tuning recommendations with the rule logic to implement them, and SOC process improvement guidance prioritised by impact. Findings are delivered in real time through the CovertSwarm Portal throughout the engagement.

How often should we run purple team exercises?

The right cadence depends on your threat exposure, SOC maturity, and how frequently your environment changes. After a major tooling change, a cloud migration, or a red team engagement, a targeted exercise produces the most immediate value. Organisations with mature SOC programmes benefit from running exercises on a quarterly basis to measure improvement over time.

Does CovertSwarm work with our existing SOC team and tooling?

Yes. Purple teaming is designed to work with your existing environment, not replace it. We work directly with your SOC analysts using your SIEM, EDR, and detection tooling. The outcome is detection rules and process improvements that work in your specific environment, not generic guidance based on a standard configuration.
