Security Operations

A SIEM full of unactioned alerts isn't security monitoring. It's noise with a subscription fee. Security operations is the engineering work that turns log volume into signal a team can actually act on.

Delivered from our base in Utrecht, available to organisations across the Netherlands.

The problem

Most SIEM deployments follow the same pattern: connect the data sources, enable the vendor's default detection content, and declare monitoring in place. The result is alert volume disconnected from real risk: analysts either drowning in low-value alerts or, worse, tuning everything down until genuine threats stop triggering anything at all.

Business impact

Detection gaps don't announce themselves. An environment that looks monitored on paper but isn't actually generating meaningful alerts provides false confidence: the kind that means a real intrusion runs for weeks before anyone notices, rather than hours.

Built for signal over noise, mapped to how attackers actually operate.

SIEM platforms

Engineering and tuning for Microsoft Sentinel, Splunk, Elastic and QRadar, whichever platform you've already invested in.

Microsoft Sentinel

Analytics rules, workbooks and automation built for Sentinel specifically, for organisations standardised on the Microsoft security stack.

Detection engineering & detection-as-code

Detection content version-controlled and tested like software, not a pile of ad-hoc rules nobody remembers writing.

MITRE ATT&CK alignment

Coverage mapped against a recognised framework, so gaps are visible rather than assumed away.

Threat hunting

Proactively looking for the activity your existing alerts wouldn't catch.

Log engineering

Making sure the right logs are actually collected, parsed, and retained before you need them, not discovered missing during an investigation.

SOAR & incident triage

Automating the repetitive first steps of triage so analysts spend time on the judgement calls.

The detection lifecycle we build and operate against, from raw telemetry through to the lessons that feed back into better detection:

How this engagement runs

01

Assess

Understand the current state, real risk, and what's actually driving the need for this work.

02

Architect

Design the controls and approach that fit your environment, not a generic template.

03

Implement

Deploy and integrate the work: configuration, code, or process, whichever the engagement calls for.

04

Validate

Test that it actually holds up, rather than assuming it does because it's been deployed.

05

Improve

Feed findings back in as your environment and the threat landscape change.

Who this is for

  • Organisations with a SIEM in place but low confidence in what it would actually catch
  • Teams drowning in alert volume with no clear prioritisation
  • Companies standardised on Microsoft Sentinel who haven't moved past default analytics rules
  • Businesses that need demonstrable detection coverage for compliance or customer assurance

What you get

  • A log source and coverage gap analysis
  • Tuned, version-controlled detection content mapped to MITRE ATT&CK
  • SOAR automation reducing manual triage time
  • A threat-hunting process for the gaps automated detection wouldn't catch

Frequently asked questions

We have a SIEM but feel like we're not getting value from it. Is that normal?

Very common. A SIEM that's connected to data sources but never given tuned detection content generates either too much noise to act on or too little signal to matter. The tooling is rarely the problem; the engineering behind it usually is.

Do you provide 24/7 monitoring, or just the engineering behind it?

Our focus is the engineering: detection content, tuning, log pipelines, and the automation that makes monitoring effective. Ongoing monitoring coverage and SLAs are scoped per engagement; ask us directly about what's realistic for your organisation.

What's MITRE ATT&CK, and why does coverage against it matter?

It's an industry-standard catalogue of real attacker tactics and techniques. Mapping your detection coverage against it shows you concretely what you'd catch and what you wouldn't, rather than assuming your SIEM covers everything because it's connected to your logs.
