Rapid7 InsightIDR
- +Among the fastest SIEM deployments in this table
- +Good out-of-the-box detection content requiring little tuning
- +Integrates cleanly with Rapid7 vulnerability management
- −SaaS only, with no self-hosted option
- −Less customisable than platforms built around a query language
Best for SMB and mid-market teams wanting quick time to value without deep expertise
Watch out Per-asset pricing plus SaaS delivery limits both flexibility and residency control
Splunk Enterprise Security
- +Self-hostable — Splunk Enterprise runs on your own infrastructure
- +Splunkbase app ecosystem is far larger than any competitor listed here
- +Search language is exceptionally powerful for investigation and hunting
- −Ingest-based licensing is the single most common driver of SIEM cost escalation
- −Requires significant expertise and headcount to operate well at scale
Best for Large enterprises with the budget and staff to exploit the platform fully
Watch out Model three-year cost against realistic data growth, not today's volume
