Leave the legacy SIEM.
Keep every log.
Vijilan migrates enterprises, MSPs and MSSPs from Splunk, QRadar, LogRhythm and every other legacy platform to CrowdStrike Falcon Next-Gen SIEM — dual-write pipelines, parallel-run validation and a 24/7 SOC watching both sides until parity is proven.
Why teams are migrating their SIEM.
Ingestion pricing punishes visibility
Per-GB and workload pricing force teams to filter out logs to control spend — which is how blind spots happen. Index-free economics remove the trade-off between budget and coverage.
Legacy platforms are in flux
Splunk under Cisco, QRadar sold to Palo Alto Networks and shifting roadmaps at LogRhythm-Exabeam all mean the same thing: renewal risk you don't control. Migrating on your schedule beats migrating on theirs.
Index architecture slows at scale
Index-based search degrades exactly when you need it most — during an incident. Falcon Next-Gen SIEM is index-free: 150× faster search while processing petabyte-scale daily volumes.
Consolidation onto one console
SIEM, native XDR, identity protection and Falcon Fusion SOAR in one platform ends the swivel-chair between point products — and Charlotte AI triages across all of it.
Platform-specific migration guides.
Every source platform fails differently, so every program starts from a platform-specific playbook: what breaks, what maps cleanly, and what to renegotiate before your renewal date.
Another platform?
Anything that emits syslog, API or agent telemetry routes through the same dual-write pipeline.

The same zero-visibility-loss sequence behind every platform program. Rollback at every stage.
- 01
Discovery & Audit
Complete inventory of source data sources, saved searches, dashboards, alerts, compliance reports and custom apps. Map dependencies and identify optimization opportunities.
- 02
Architecture Design
Design target Falcon Next-Gen SIEM topology with a Falcon Onum or Cribl pipeline. Define parallel-run infrastructure, data routing and retention policies. Size for current and projected data volumes.
- 03
Pipeline Deployment
Deploy Cribl or Falcon Onum for dual-write. Data flows to both the old SIEM and Falcon Next-Gen SIEM simultaneously. No source reconfiguration required for most data types.
- 04
Detection Migration
Convert detection rules, correlation searches and scheduled reports to Falcon Next-Gen SIEM equivalents. Improve signal-to-noise ratio during conversion. Validate against historical incident data.
- 05
Parallel Run & Validation
Both SIEMs active and monitored 24/7 by the Vijilan SOC. Compare alerts, dashboard outputs and compliance reports side-by-side. Tune until output parity is confirmed.
- 06
Phased Cutover
Source-by-source cutover with rollback capability at every stage. High-priority sources first, then expand. The legacy SIEM remains accessible throughout for historical queries.
- 07
Optimization & Managed Ops
Tune detections, build new Falcon Next-Gen SIEM dashboards, enable Charlotte AI investigation workflows and transition to Vijilan 24/7 managed SOC operations.
Migrate clients under your brand.
The whole program is white-label: your logo on the assessment, the reports and the parallel-run reviews. Move a client off their aging SIEM once, then keep them on NextDefend™ with our 24/7 SOC behind your service desk.
How white-label delivery worksData-sovereign, compliance-first.
Enterprise migrations run through Professional Services with regional data-residency options across the US, UK, Australia, South Africa and the Gulf — retention mapping, framework alignment and audit evidence included.
Vijilan for enterpriseCommon questions.
How long does a SIEM migration take?+
A typical mid-market migration runs about 12 weeks end to end: discovery and audit, architecture design, pipeline deployment, detection migration, a parallel-run validation window, phased cutover and post-cutover optimization. Larger enterprise estates run longer, but the phases are the same and every phase has a rollback point.
Will we lose visibility during the cutover?+
No. The program is built around dual-write: a Cribl or Falcon Onum pipeline streams every source to both your current SIEM and Falcon Next-Gen SIEM at the same time. Both platforms stay live and monitored 24/7 until output parity is confirmed, and cutover happens source by source with rollback at every stage.
What happens to our historical log data?+
You choose per retention requirement: keep the legacy SIEM accessible read-only for historical queries through the retention window, backfill priority datasets into Falcon Next-Gen SIEM through the pipeline, or archive to low-cost object storage. Compliance retention is mapped during discovery so nothing is orphaned.
Do our detection rules and dashboards carry over?+
Yes — they are converted, not copied. Correlation searches, detection rules, scheduled reports and dashboards are rebuilt as Falcon Next-Gen SIEM equivalents and validated against historical incident data. Most teams end up with better signal-to-noise than before, because the conversion pass retires stale and duplicate rules.
Which SIEM platforms do you migrate from?+
We maintain dedicated migration programs for Splunk, IBM QRadar, LogRhythm and Exabeam, ArcSight, Elastic SIEM, Rapid7 InsightIDR and Sumo Logic. Anything that emits syslog, API or agent telemetry can be routed through the same pipeline, so other platforms are handled case by case.
Who runs the SIEM after the migration?+
That's your call. NextDefend™ comes in three independent offerings — Deploy (we build it, you run it), Sustain (you run it, we keep it healthy) and Operate (our 24/7 SOC runs detection and response end to end). MSPs and MSSPs can white-label the entire service.
How is a migration priced?+
Every migration starts with a free, fixed-scope migration assessment: we audit the environment, map data sources and detection rules, and deliver a migration plan, typically within 5 business days. Commercial terms are shared through the assessment and the partner portal rather than published as list prices.
"As our business grew, we wanted to modernize our SIEM foundation and extend SOC coverage without changing who we are as a security organization. Our goal was to evolve thoughtfully, not reactively."
