An attacker who gets in is seen before they reach the crown jewels. Not because coverage was ticked off, but because the detection has been tested.
Key challenges
You have a SIEM, a SOC or an MDR contract and still no coherent picture that holds. A dashboard is not detection that catches what matters.
14
median dwell time, days
The time between entry and discovery is falling, but an attacker still has days to move across your estate. And roughly half of intrusions are still surfaced from outside the organisation, not by your own detection.

60%
of alerts are never investigated
Alerts pile up, capacity is finite and the majority are never investigated. A sizeable share are false alarms: detection on poorly configured sources has analysts chasing noise rather than threat. That is a process problem, not a tooling problem.

30%
of attacker techniques demonstrably covered
Most SOCs lean on a platform’s default rules and assume the detection works. But coverage that has never been tested against what an attacker actually does will not fire at the moment it has to. The question is not whether you have a SIEM, but which techniques you demonstrably catch.

Regulators and leadership do not ask how many alerts come in or whether round-the-clock coverage is ticked off. They ask whether the organisation would see it when it goes wrong, and whether the monitoring spend is aligned to the risk. That is the difference between a green light and tested detection.
The difference
Not whether you monitor, but whether the detection fires on the techniques that matter to you, and whether it holds once an attacker is inside.
Detection is bought as a product: a SIEM switched on, an MDR contract signed, round-the-clock ticked off. Success is measured in connected sources and processed alerts.
We first decide what you must reliably see and which techniques matter. The model, the sources and the roles follow from that, not the other way round.
Detection content comes from the tool’s defaults, not from what attackers in your sector actually do. Where you are blind stays invisible.
We map your real coverage against the techniques of the actors relevant to you, via MITRE ATT&CK. The gaps become visible before an attacker finds them.
The detection counts as working because the rule exists. Whether an alert actually fires against a real attacker technique is never put to the test.
We test the detection with attack simulation and purple-teaming: does it fire, and at the right moment. Only then do you know the coverage is more than an assumption.
The contract suggests the detection is handled. But when an incident hits, you face the board, not the provider, and a grip on the execution is missing.
You can outsource the work, not the accountability. We place the roles and the response so you keep control, independent of your MSSP.
How it works
On the left, what feeds detection; in the middle, the order that decides and tests; on the right, what you keep. Your existing SIEM, SOC and MDR contract stay in place.
The distinction
The usual advice buys detection as a product: switch on a platform, sign a contract, tick off coverage. So we test first whether the detection fires at all against real attacker techniques before we count it as working. Not an assumption that the rule fires, but evidence that it does.
That works because the bottleneck rarely sits in the tool, but in which use cases are built, which sources are connected and who acts on the alert. The quality of a SOC comes from people and process, not from the amount of tooling.
Your existing SIEM, SOC and MDR contract stay in place. We do not build a new layer on top, we make the detection you already have demonstrably work. A tool or service is a means, not an end.
The detection is yours, not the provider’s who runs it. Co-managed, in-house or MDR is a choice that fits your maturity and what you can sustain. We advise the model that works, regardless of which platform sits beneath it.
The market delivers a report saying monitor your estate and leaves the execution with you, or the outsourced Tier 1 who drops off the moment it gets hard. The same senior who decides what must be detected builds the detection and tests it.
Sector experience
We delivered the leading SIEM and SOAR platforms in these sectors. Where asked, we advised on selection and setup.
From practice
A global industrial multinational missed attacks while the SIEM bill climbed. We built a cost-efficient multi-SIEM architecture that sees more, carried by the same team.
