SIEM Services

Get more from your SIEM — from first migration through to a tuned, fully engineered detection platform.

CyberTI® engineers build and run SIEM platforms every day. Whether you are moving off a legacy SIEM or hardening an existing deployment, we bring the detection content, architecture and operational discipline to make it work.

Most SIEM problems are not platform problems. They are coverage problems wearing a platform's badge: rules that were never mapped to a technique, log sources that stopped arriving without anyone noticing, an alert queue nobody trusts enough to work, and a retention window shorter than the time it takes to discover an intrusion. Changing product does not fix any of that on its own.

So both services here are built around evidence rather than migration mechanics. A migration runs through a coverage gate: old and new are mapped to MITRE ATT&CK® and compared, and the outgoing platform stays the system of record until the new mapping matches or exceeds it. Nothing is switched off on a promise.

Ongoing engineering is the same discipline applied continuously — 350+ CyberTI-authored detections on top of a 1,300+ rule ATT&CK-mapped baseline, reviewed weekly, plus the cluster sizing, retention and cost tuning that decides whether a platform stays affordable once real traffic hits it.

Both are delivered by Australian-based engineers who operate these platforms themselves rather than handing you a report and leaving.

SIEM SIEM Security Information and Event Management Centralised collection and correlation of security-relevant events from across an estate, so activity spanning several systems is recognised as a single story. Full glossary →

DaC DaC Detection as Code Managing detection rules the way software is managed: version-controlled, peer-reviewed and tested before they reach production, so a rule change is traceable to who made it and why. Full glossary →

Parallel run Parallel run Parallel run Running the outgoing and incoming SIEM side by side through a migration, so detection coverage is proven on the new platform before the old one is switched off. Full glossary →

Normalisation Normalisation Field normalisation Mapping fields from many different log sources onto one common schema, so a single detection rule works across all of them instead of being rewritten per source. Full glossary →

A platform is only as good as what it notices

Detection content built, tuned and maintained against a threat landscape that does not hold still for your review cycle.

Nothing is switched off until coverage is proven

Five phases with a hard gate in the middle. The gate is the point.

SIEM Services in detail

Each of these is a service in its own right. Follow any of them for the full picture.

Two services, one practice. Most engagements start with the first and continue into the second.
