SIEM strategy and use cases
What the platform must detect for your business, the log sources that reveal it, and the response each detection triggers.
Capability 07
SIEM and SOC
Modernise detection, response and security operations. We design and build the SIEM, engineer the detections, automate the response and enable your team to run it. We do not operate a monitoring service, and we say so.

- Threat hunting is what alerts can't do
The challenge
Drowning in alerts is not a detection strategy.
Most estates have a SIEM. Few get decisions out of it: thousands of daily alerts, logs in silos, events without context and analysts sifting by hand while the clock runs. The platform was deployed with default rules for a non-default estate, and nobody defined what it must detect.
A SIEM earns its keep by deciding: which event matters, how much, and what happens next. Making it decide is engineering work, and it is the work we do.
What we deliver
Offerings.
Take one offering on its own, or combine them into a programme with a named lead and agreed exit criteria.
SIEM build and migration
Platform selection where needed, log source onboarding, normalisation, retention and cost control on the platform you own.
Detection engineering
Correlation rules, behavioural baselines and tuning until alerts are believable, with coverage mapped to attacker techniques.
SOAR playbooks
Containment, suspicious-login investigation, phishing response and enrichment automated, so analysts spend their time on judgement.
SOC process design and enablement
Roles, runbooks, drills and metrics for your own team, whether in-house or with a provider you choose.
Detection validation
The technique is run, the SIEM is checked, the gap is closed: purple teaming as a routine, not an event.
Approach
How an engagement runs.
A named practice lead from scoping to close, with deliverables agreed before work starts.
Define
Objectives, use cases and the sources that serve them.
Build and tune
Log sources onboarded, rules customised, thresholds refined.
Automate
Playbooks for the repetitive; integration across endpoint, cloud and network tools.
Validate and improve
Drills, threat intelligence refreshed, rules tuned from real incidents.
Outcomes
What changes for you.
Measured outcomes from real engagements will be published here once clients consent.
Believable alerts
Noise measured and cut, so the alerts that fire are the ones that matter.
Faster response
Detection to containment shortened by automation your analysts trust.
Coverage you can show
Detections mapped to techniques and validated, with the gaps on a plan.

Frequently asked.
Do you run a SOC for clients?
No. Rhinexa does not operate a 24-hour monitoring service. We build and tune the platform, engineer the detections and enable your team, or the provider you choose, to run it.
Which SIEM platforms do you work with?
The one you own or the one we select with you. We have no obligation to any vendor and we say when a platform is the wrong fit.
Where does Rhinexa Sentinel fit?
It adds network detections and a tamper-evident record that host logs cannot provide, forwarded into the SIEM and ticketing tools you already run.
How long does a SIEM uplift take?
It depends on the log sources and the state of the platform. Typical engagements run from a few weeks for a focused uplift to several months for a full platform build, delivered use case by use case so value arrives early.
