Purple Team Exercise · Portsmouth
Purple Team Exercise in Portsmouth
Purple team exercises for Portsmouth organisations, where the value comes from the defenders being in the room. Attack techniques are run deliberately and openly while the security team watches what their tooling shows — so each one either produces a detection or reveals precisely where the visibility gap is.
Why this comes up
The problem
The security team has detection rules and no evidence about which techniques they actually catch.
What you get
What we deliver
- Techniques selected against threats relevant to your organisation rather than a generic list
- Each one executed with the defending team observing their own tooling
- Detection outcome recorded per technique — caught, logged only, or invisible
- Rules written or tuned during the exercise where gaps are found
- Improvements verified by repeating the technique rather than assumed
- Results documented so coverage can be tracked over successive exercises

Purple Team Exercise in Portsmouth — common questions
- Why must the defenders participate?
- Because the learning happens in the moment. Watching a technique run and seeing exactly what appears — or does not — in their own tooling teaches the team more than any report, and it lets them write and test a rule while the activity is reproducible.
- How are techniques chosen?
- From what is realistically relevant. Running an exhaustive catalogue produces volume rather than insight, whereas selecting techniques associated with threats to your sector and your technology gives results you can act on within the day.
- What are the three outcomes?
- Detected, logged but not alerted, or entirely invisible. The middle category is the most valuable finding — the evidence exists and nothing draws attention to it, which is a tuning problem rather than a tooling one and usually fixable immediately.
- How does this compare with a red team?
- It is collaborative rather than adversarial and produces improvements directly. A red team measures your response under realistic conditions; a purple team builds the detection capability that response depends on — so the second frequently belongs before the first.
- Do you work with businesses across Hampshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Portsmouth and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Portsmouth businesses do you usually work with?
- Port, ferry and defence logistics systems, plus visitor operations for the waterfront attractions. Beyond that we work across Marine & Defence, Ports & Ferries, Higher Education, Retail and Tourism.
- Do you cover the areas around Portsmouth?
- Yes — we work throughout South East, including Southampton, Chichester, Brighton. Portsmouth is an urban area of roughly 240,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
