SIEM Migration
A streamlined pathway off your legacy SIEM or XDR platform — without losing detection coverage on the way.
As your organisation's needs evolve, your current SIEM or XDR platform may no longer be the right fit — too expensive to feed, too slow to search, or too rigid to detect what you actually care about. CyberTI® offers a comprehensive, streamlined pathway off it, while maintaining compliance and operational continuity throughout.

Why migrate
Enhanced data analysis
Faster threat detection across far larger data volumes.
Cost efficiency
Most legacy SIEM licensing scales with ingest volume. Tiered storage changes that trade-off, and what you actually save depends on your data volume and retention policy — we model it during the assessment phase, before you commit.
Automated rule translation
Existing detection rules are matched to equivalents by meaning rather than by text, and where no equivalent exists the query itself is translated. Automated paths exist for the most widely deployed platforms; the rest we map ourselves.
Open, exportable data
Your data stays in open, exportable formats, and the core search and visualisation layer is available under an open source licence. Some detection content sits under a commercial licence — we tell you which before you commit.
Integrated observability
Security and operational data in one system instead of two parallel stacks.
Integrated UEBA
User and entity behaviour analytics for insider threat detection, with 0–100 entity risk scoring and a built-in Privileged Users watchlist.
Coverage you can evidence
Detection coverage mapped to MITRE ATT&CK® before and after cutover, so you can demonstrate that nothing was lost in the move.
Integrated EDR
Endpoint detection and response built into the same platform.
Full public cloud integration
Native ingest from the cloud platforms you already run.
Cloud security posture management
CSPM included rather than bought separately.
Cloud workload vulnerability scanning
Snapshot-based scanning of AWS EC2 Linux workloads, alongside CSPM coverage across AWS, Azure and GCP.
Licensing, stated up front: nine of the capabilities above sit at the top subscription tier on a self-managed deployment — malware and ransomware prevention, the prebuilt detection rule library, machine learning anomaly detection, entity analytics, Cloud and Kubernetes Security Posture Management, and endpoint query management among them. We size that subscription with you during the assessment phase, so the licence cost is visible in your business case rather than discovered afterwards.
How the migration runs
Five phases, with validation gates between them.
Why CyberTI® for the migration
Coverage on arrival, not eventually
A migration is only finished when the new platform detects at least as much as the old one did. Until then the old one is still the system of record.
Frequently asked questions
Before you commit
The major enterprise SIEM platforms have supported automated migration paths today, and anything outside that set we migrate through our own mapping process. Tell us what you are running and we will tell you which of the two applies before you commit to anything.
The platform you are leaving matters far less than the quality of your existing detection content — a well-maintained rule set migrates cleanly from almost anywhere, and a neglected one needs rebuilding regardless of where it started.
No. Automated translation does two things: it matches your existing rules to equivalents on the new platform by meaning rather than by text — so a rule still maps across even when the wording is completely different — and where no equivalent exists, it translates the query itself.
Coverage of that automation varies by source platform. The most widely deployed SIEMs have mature translation paths; less common ones are mapped by our engineers instead. We confirm which applies to you during the assessment.
Translation is not the whole job — every translated rule still needs validation against real data before it is trusted, and that validation is where our engineering time goes. But it removes the mechanical rewriting that used to make migrations a multi-month exercise.
Usually, but the honest answer is that it depends on your data volume and retention policy, and we model it before you commit.
We deliberately do not quote a headline percentage. The figures published in this market come from vendor-commissioned studies, and none of them were measured in your environment.
The structural reason savings are common is that most legacy SIEM licensing scales with ingest volume, which pushes teams into not collecting data they should be collecting. Tiered storage changes that trade-off. We model your actual numbers during the assessment phase, and if the case does not stack up we will say so.
Partly, and the distinction is worth understanding before you sign anything.
The core search and visualisation layer is available under an OSI-approved open source licence, and your data sits in open, exportable formats — so the thing that is hardest to move, your data, stays movable.
The prebuilt detection content is a different matter and sits under a commercial licence. That is normal across this market, but it is the part worth reading before you sign, and we will point you at it rather than let you discover it later.
The top tier, for the security capabilities most organisations are buying the platform to get.
On self-managed deployments, malware and ransomware prevention, the prebuilt detection rule library, machine learning anomaly detection, entity analytics (risk scoring, entity graph, watchlists), Cloud and Kubernetes Security Posture Management, and endpoint query management all sit at that tier rather than a lower one.
We size this during the assessment phase, so the licence cost is visible in your business case rather than discovered afterwards.
During and after
By running both platforms at once and proving coverage on the new one before switching off the old one.
Concretely: rules are mapped and translated, then validated against live data on the new platform while your existing SIEM is still the system of record. Coverage on both sides is mapped to MITRE ATT&CK® so the comparison is a documented technique list rather than a judgement call. Only when the new mapping matches or exceeds the old one does the old platform get decommissioned.
That parallel-run period is the part of the schedule worth protecting. Compressing it is how migrations quietly lose coverage.
Migrations typically take a few weeks to complete, depending on the complexity of your environment, the number of data sources and the volume of historical data being moved.
Automated rule translation is the main reason that is weeks rather than months — the mechanical rewriting that used to dominate the schedule is now largely automated, leaving validation as the work that takes real time.
Downtime is minimised through careful planning, and cutover work is scheduled during off-peak hours.
We run the new platform in parallel with the old one through the transition, so detection coverage does not lapse while the switch happens.
Comprehensive validation and secure transfer methods are used throughout, with integrity checks at each stage so any discrepancy is caught during migration rather than discovered later.
Yes. Dashboards, detection rules, retention policies and ingest pipelines are all shaped around how your team actually works rather than around a reference deployment.
Pricing is based on system complexity, data volume and the scope of services required. We scope the work after the initial assessment so the number reflects your environment rather than an average.
