Detection engineering
Writing and tuning detection logic against specific attacker techniques, so an alert tells a responder something they can act on.
Defensive Security
Defensive Security
Engineering and advisory support that turns security signals into detection, response, and resilience — building the capability your team runs, rather than operating it on your behalf.
You receive practical detection logic, monitoring improvements, hardened infrastructure, and incident readiness your own team can operate.
What we offer
Areas of work.
The exact combination is agreed during scoping rather than assumed — these are the areas an engagement is built from.
Security monitoring architecture
Reviewing and designing how telemetry is collected, routed, and surfaced — the structure your monitoring runs on, designed for your team to operate.
Logging and alerting
Establishing what gets logged, retained, and escalated, so an investigation has the evidence it needs rather than gaps.
Security controls
Assessing and strengthening the preventive and detective controls already in place, and identifying where coverage is thin.
Infrastructure hardening
Reducing exposure across servers, services, and configuration, prioritised by what an attacker could actually reach.
Vulnerability management
Building a process for finding, prioritising, and tracking weaknesses over time rather than treating each one as a one-off.
Incident Response & Readiness
Preparing the plans, workflows, and decision points a team needs before an incident — advisory and readiness work, not standby response.
How we help
How an engagement runs.
Work starts with what you already have: existing telemetry, controls, and processes. We identify where detection or response would break down, then build and hand over the improvements — detection logic, logging changes, hardened configuration, or response workflows — so the capability stays with your team once the engagement ends.

Engagement output
- Practical detection logic
- Monitoring, logging and alerting improvements
- Hardened infrastructure and control recommendations
- Incident readiness guidance
The exact artifacts depend on what the engagement covers, and are confirmed during scoping.

Related evidence
What the work looks like.
Detection work is easier to judge from an example than a description. The detection engineering demonstration shows a rule mapped to a specific attack technique and what it is meant to trigger on, and the sample report shows how findings and recommendations are written up. Both are demonstrations rather than client work, and we can walk through them on a call.
Scope
What this service is, and what it is not.
Being clear about the limits matters as much as describing the work.
Engineering and advisory, not a managed service
We build and improve defensive capability. We do not operate a security operations centre, and we do not monitor client environments on an ongoing basis.
No continuous or 24/7 monitoring
Monitoring work means designing and improving how your monitoring functions. Watching your systems around the clock is not part of this service.
Incident response work is readiness work
We help you prepare — plans, workflows, logging, and decision points. We do not offer on-call breach response, incident-response retainers, or guaranteed response times.
Capability stays with your team
The output is something your own people operate. Where hands-on implementation is needed, it is scoped and authorised explicitly.
