Security Operations

End-to-end Security Operations Centre design and uplift across people, process, and technology.

Two intervals decide how much an incident costs: how long until you detect it, and how long until you contain it. Both are products of detection engineering and rehearsed decision rights, which is why a SOC is an operating model rather than a tool purchase.

A Security Operations Centre is not a product you install. Organisations buy the SIEM, hire two analysts, and discover a year later that they have an expensive log archive and an alert queue nobody trusts. The technology is rarely what failed. What failed was the absence of an operating model: who is on shift, what they are expected to do with a given alert, when it escalates, and who decides to pull a system offline at two in the morning.

Detection engineering is the part that produces the value, and it is a continuous discipline rather than a deployment task. That means a use-case backlog driven by the threats that actually apply to your sector, coverage mapped against MITRE ATT&CK so you can state plainly what you would catch and what you would miss, and alert quality measured rather than assumed. A rule that fires forty times a day and is dismissed forty times a day is worse than no rule, because it trains people to dismiss.

On top of that sits automation, including AI-augmented triage and enrichment to cut the analyst toil that causes burnout and turnover. And underneath all of it, metrics that mean something to a board: not events processed, which measures nothing anyone cares about, but coverage, dwell time, and how quickly a real incident moves from signal to contained.

You might need this if

  • The SIEM is deployed and nobody quite trusts what comes out of it
  • You cannot state which attack techniques you would detect and which you would miss
  • Detection content has not meaningfully changed since the vendor configured it
  • Escalation out of hours depends on one person answering their phone
  • Analysts are leaving, and exit conversations mention the alert queue

Who it's for

Organisations standing up a SOC for the first time, or maturing an existing detection-and-response capability under regulatory or board pressure.

How the engagement runs

  1. 01

    Target operating model

    Roles, shift patterns, escalation paths, and decision rights, including who is authorised to take disruptive action and on what basis. Most SOC problems are process problems wearing a technology costume.

  2. 02

    Detection coverage and engineering

    A use-case backlog built from your real threat profile, coverage mapped to MITRE ATT&CK, and tuning driven by measured alert quality rather than by whoever complains loudest.

  3. 03

    Automation and triage uplift

    Enrichment and triage automation, including AI-assisted workflows where they genuinely help, so analysts spend their attention on judgement rather than on assembling context.

  4. 04

    Measurement and handover

    Metrics that report upward honestly, a tested incident-response path out of the SOC, and the team coached to run and extend the capability themselves.

What's delivered

  • Target operating model for the SOC, with roles, shift patterns, and escalation paths
  • Detection engineering: use-case backlog, SIEM tuning, and alert quality measurement
  • AI-augmented triage to cut analyst toil and shorten mean time to respond
  • Threat-intelligence integration and a tested incident-response playbook
  • Metrics that report to the board, not just the console

Common questions

Should we build in-house or use a managed provider?
It depends on what you need to keep. Managed providers are good at coverage and poor at context, so the usual answer for a regulated or complex environment is a hybrid: outsource the monitoring hours, keep the detection engineering and the incident decision-making in-house. I will give you a straight recommendation for your situation rather than a preference.
Do we need round-the-clock coverage?
Fewer organisations need it than buy it. The honest test is what you would actually do at three in the morning: if nobody is empowered to act until business hours anyway, you are paying for observation rather than response. Fix the decision rights first, then decide on the hours.
Which SIEM should we buy?
Usually the one you can staff and maintain, not the one that demonstrates best. I am not a reseller and take no vendor commissions, so this is a design question rather than a procurement recommendation.
What does a good SOC actually look like?
It can state its detection coverage and its gaps without hedging, its alerts are trusted enough to be acted on, its people are not silently drowning, and an incident moves from signal to containment through a path that has been rehearsed rather than improvised.
