Key Takeaways
- A purple team exercise only works if red and blue teams operate in the same room, watching the same alerts, in real time.
- Scope your first engagement around 5 to 8 techniques mapped to threats your industry actually faces, not a generic top 10 list.
- MITRE ATT&CK is the shared language that lets you score what you caught, what you missed, and why.
- The exercise itself is the easy part. The value shows up when findings turn into SIEM rules, EDR policies, and updated playbooks.
- Purple teaming pays off when it is a recurring habit, not an annual fire drill.
Half of successful attacks never trigger an alert on the endpoint, according to N-able’s 2026 State of the SOC Report. That is not a tooling problem you can buy your way out of. It is a validation problem, and purple teaming is the fastest way to find out where your blind spots actually are before an attacker does.
How to scope a first purple team engagement
Most purple team programs die in the planning stage because someone tries to test everything at once. Start smaller than feels comfortable, and lock down scope, participants, rules of engagement, and success criteria before day one. A SIEM alert that nobody read does not count as a detection, so agree on what “detected” means up front.
How to prioritize which attack techniques to emulate
Pick 5 to 8 techniques tied to a threat actor your industry actually deals with. Credential access, defense evasion, and persistence techniques cover a large share of real intrusions and give you a baseline worth building on. Relevance beats coverage in a first exercise.
How do purple teams choose threat actor profiles
Pull from recent threat intelligence, incident reports in your sector, or your own past incidents rather than a generic checklist. A fintech company and a healthcare provider are not defending against the same playbook, so the profile should reflect the threats you actually face, not a list borrowed from someone else’s industry.
How to convert threat intelligence into emulation plans
This is mostly a translation exercise. Take the TTPs from a threat report, map each one to a MITRE ATT&CK technique ID, and write a one line test for each. By the time you are done, every line item in the report has a corresponding action your red side can run.
How to run a purple team exercise step by step
Once scoping is done, the exercise itself follows a simple rhythm:
- Brief the room. Confirm scope, timing, and what “stop” looks like. Everyone should know the plan before the first command runs.
- Execute one technique at a time. The offensive side runs a single technique, whether that is a scheduled task for persistence or a credential dump. No stacking multiple techniques before checking results.
- Watch the blue side in real time. Did an alert fire? Did an analyst notice? How long did it take from execution to detection? Write the number down, even if it is embarrassing.
- Pause and compare notes. This is the actual purple part. Red walks through what they did, blue explains what they saw or did not see, and you name the gap out loud before moving to the next technique.
- Repeat for each technique on the list, then debrief as a group.
How to map purple team exercises to MITRE ATT&CK
After each technique, mark the corresponding ATT&CK technique as detected, partially detected, or missed. Over a few exercises, that scorecard becomes a heat map of your actual coverage, which is a far more honest picture than a compliance checklist.
How to combine tabletop and live purple exercises
If your team is newer to this, walk through a scenario verbally first so everyone understands the attack chain, then run the live version. It slows the first session down but prevents confusion about what is actually being tested versus discussed.
How to close the loop between offense and defense
An exercise that ends with a slide deck nobody opens again was a waste of everyone’s time. The loop only closes when findings turn into changes, not when the session ends.
How to feed pentest results into soc playbooks
If an analyst did not know how to respond to a technique, that is a playbook gap, not a training gap. Update the runbook the same week, while the exercise is still fresh in everyone’s memory.
How to validate incident response playbooks with simulations
Did the escalation path work? Did the right people get paged? A purple team exercise is one of the few chances to test IR process without an actual incident on the clock.
How to document purple team exercise results
A short gap register works better than a long report: technique, what happened, what is missing, who owns the fix, and by when. The teams that get the most out of purple teaming treat this register as the actual deliverable, not the exercise itself.
How to align purple teaming with detection engineering sprints
Do not let gap findings sit in a backlog separate from the team that writes detection logic. Feed them directly into the same sprint cycle so SIEM tuning happens on a schedule, not whenever someone remembers.
How to build a continuous detection validation program
A single purple team exercise gives you a snapshot. A continuous program gives you a trend line, and that is what actually shows whether your SOC is improving. Track the same metrics every cycle: detection rate, mean time to detect, and how many previously missed techniques you closed since the last round.
How to schedule recurring attack simulations
Even a monthly half day session covering 8 to 12 techniques beats one big annual engagement. Smaller, more frequent tests catch detection regressions when someone tweaks a SIEM rule or rolls out a new log source.
How to run purple teaming with a lean security team
You do not need a dedicated red team function to start. A single person who understands offensive tooling can run atomic tests against your environment while the rest of the SOC watches and responds. Keep the scope tight and it stays manageable.
Where Secure.com’s SOC Teammate fits in
Most of the friction in purple teaming is not the exercise itself. It is everything around it: pulling telemetry from five different tools to confirm what fired, manually mapping each technique to ATT&CK, and writing up a gap register by hand after everyone has already moved on to the next fire.
Secure.com’s SOC Operations Teammate integrates with your existing SIEM and EDR stack, so when a purple team technique runs, it correlates the resulting alerts, maps them to MITRE ATT&CK tactics and techniques, and surfaces exactly what was detected, missed, or partially caught. Instead of an analyst manually correlating logs from multiple consoles after the fact, the detection scoring happens in real time as the exercise runs, and the findings are delivered directly into Slack, Teams, Jira, or ServiceNow—where your team already works. That turns a purple team exercise from a manual, occasional event into something a lean team can run monthly—without burning 20+ hours per week on manual correlation and reporting.

Conclusion
Purple teaming works because it turns an assumption about your defenses into a fact, one technique at a time. The exercise itself does not need to be complicated. Scope it tight, run it step by step, and treat the gap register that comes out the other side as the real deliverable. Do that on a repeatable schedule, and you stop guessing whether your SOC would catch a real attack and start knowing.
