Purple Team Assessment

We start by agreeing which adversaries matter to you. A payments company faces different techniques than a hospital or a logistics firm, so we build the emulation plan around the groups and TTPs realistic for your sector, drawn from MITRE ATT&CK and current threat intelligence. Together we set the objectives, the rules of engagement, and the metrics we will measure against.

We execute techniques in a controlled sequence: initial access, execution, persistence, privilege escalation, credential access, lateral movement, and exfiltration. After each one we pause with your defenders and check the evidence. Did the EDR alert? Did the log reach the SIEM? Did a rule fire, or did the activity pass unseen? Every technique is recorded as detected, partially detected, or missed, with the exact telemetry that should have caught it.

Where a technique was missed, we do not just note it. We work with your team to build or tune the detection against your real telemetry, using the log sources you already have, then rerun the technique to confirm the rule fires without drowning analysts in false positives. This is where a purple team security assessment pays for itself: you leave with detections that work, not a wish list.

Throughout, we measure how quickly the team detects and responds, and where handoffs stall. The report captures the before-and-after coverage, the new detections, the response timings, and a prioritised plan for the gaps that remain. We walk your leadership and your analysts through it live, so the people who run your defence day to day own the outcome rather than reading about it second-hand.

Detections cannot fire on data the SIEM never received. We routinely find endpoints without EDR, PowerShell or command-line logging switched off, cloud audit logs disabled, and network segments with no visibility at all. Fixing the pipeline often matters more than writing another rule.

Detection content that was never validated against a live attack tends to fail quietly: a rule scoped too narrowly, a field mapping that broke after a log-format change, or an alert routed to a queue nobody watches. Running the actual technique is the only honest test of whether the rule works.

Sometimes the alert fires and nothing happens, because it is one of a thousand a day. We measure how noise, unclear runbooks and manual handoffs stretch your response time, and we help tune signal-to-noise so the alerts that matter get acted on.

Initial access often gets caught while the far more damaging steps, such as credential dumping, Kerberos abuse and lateral movement, go unseen. We map exactly where along the kill chain an attacker becomes invisible to you, which is the coverage most worth closing.

A red team is covert and goal-driven: get to the crown jewels without being caught, and report how. It is the right choice when you want to test whether you can be breached and how your team reacts to a genuine, unannounced intrusion. A purple team is open and collaborative, optimised for improving detection breadth quickly rather than proving a single attack path.

If you have invested in a SOC, an EDR and a SIEM and want to know what they actually catch, purple team gives you far more coverage improvement per euro than a covert red team. Many clients run a purple team first to raise their baseline, then a red team later to test the improved defence under realistic conditions. We are happy to advise which fits your maturity, and there is no upsell in that advice; the honest answer sometimes is that you are not ready for a red team yet.

Typical scenarios include phishing and initial-access payloads, living-off-the-land execution through PowerShell and scripting hosts, credential theft such as LSASS access and Kerberoasting, token abuse, lateral movement over SMB and remote services, defence evasion, and staged data exfiltration. Each is drawn from real intrusion tradecraft and mapped to its ATT&CK technique so nothing is abstract.

We work with EDR platforms such as Microsoft Defender, CrowdStrike and SentinelOne, SIEMs including Microsoft Sentinel, Splunk and Elastic, plus identity logs from Active Directory and Entra ID and cloud audit trails from AWS, Azure and GCP. The point is to prove and improve detection in your environment, on your licences, with rules your team will maintain after we leave.

For financial entities, DORA introduces threat-led penetration testing (TLPT) aligned with the TIBER-EU framework, which expects intelligence-driven emulation of real adversaries and evidence of detection and response capability. Our emulation plans and coverage reporting map directly to that expectation.

The results feed ISO 27001 continual-improvement and incident-management controls, support NIS2 obligations on detection and response for essential and important entities, and give you a MITRE ATT&CK coverage baseline you can track over time. Reports are written under NDA and structured for both your board and your auditors.
