Migrate to
Falcon Next-Gen SIEM.
Vijilan's managed migration program moves you from ArcSight to CrowdStrike Falcon Next-Gen SIEM with zero visibility loss. Escape ingestion-based pricing. Deploy 150× faster search. Keep 24/7 SOC coverage throughout.
ArcSight
Four owners · ~426 users · declining ecosystem
CrowdStrike Falcon Next-Gen SIEM
Index-free · 150× faster · Native XDR · Charlotte AI
ArcSight has changed ownership four times and is now part of OpenText. The product is in maintenance mode. Customers are evaluating modernization paths.
Four ownership transitions
HP → HPE → Micro Focus → OpenText. Each transition delayed the roadmap. Customers absorbed the cost. Time to choose a platform with a clear future.
Declining ecosystem
Public Gartner data shows ArcSight at the bottom of analyst rankings and customer counts in steep decline. Skilled ArcSight talent is increasingly rare and expensive.
Ingestion pricing punishes visibility
Per-GB pricing forces teams to filter logs to control costs, creating dangerous blind spots.
Index architecture doesn't scale
ArcSight's index-based architecture slows at scale. Falcon Next-Gen SIEM's index-free design delivers 150x faster search while processing 1PB+ daily.
No native EDR/XDR
ArcSight requires third-party EDR feeds. Falcon Next-Gen SIEM ships with Falcon Insight XDR integrated.
Compliance reporting is brittle
Reports built against ArcSight's legacy data model frequently break across upgrades. Falcon Next-Gen SIEM ships compliance pack templates maintained by CrowdStrike.

| Search Speed | Slows at scale (index-based) | 150x faster (index-free) |
| Storage Costs | Expensive hot/warm/cold tiers | 50% lower via Falcon Onum |
| Native XDR | None | Falcon XDR fully integrated |
| AI Investigation | Basic / none | Charlotte AI: automated triage |
| EDR Integration | Third-party required | Native Falcon Insight XDR |
| Identity Protection | Add-on purchase | Falcon Identity Protection native |

A 7-step ArcSight migration.
Zero visibility loss. Parallel-run validation. 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.
Common questions.
Why migrate from ArcSight now?+
ArcSight is in maintenance mode under OpenText. Ecosystem skills are rare and expensive. Customers who want a modern platform with clear forward investment are evaluating alternatives.
How long does an ArcSight migration take?+
Typical migrations run 10-20 weeks with parallel-run validation. ArcSight environments tend to have deep customization that takes longer to map.
Can our ArcSight rules and dashboards be converted?+
Yes. The Discovery & Audit phase inventories your detection content and dashboards and we convert them. Charlotte AI assists during the transition.
Will we lose visibility during the migration?+
No. Parallel-run keeps both SIEMs hot. The Vijilan SOC monitors both until cutover.
How much can we save by switching?+
Customers typically see 40-60% lower TCO through index-free pricing, native EDR/XDR consolidation and reduced data filtering. ArcSight migrations also reduce specialized-talent costs.
Do we need to wait for our ArcSight contract to expire?+
No. Many customers begin migration during the renewal window to avoid overlap fees by cutover date.
