| Privacy | Active public advisory program, but multiple critical CVEs disclosed 2025-2026, including unauthenticated RCE . patch fast.⁸ | No confirmed platform breach in reviewed sources; agent components carry published CVEs and a 2016 incident is documented. |
| Support quality | No support-quality evidence in reviewed sources | No support evidence in reviewed sources |
| Public sentiment | Reviews praise Splunk's power and ecosystem but repeatedly flag cost, complexity, and a steep learning curve; some teams are switching away.¹ | Users praise the unified visibility and integration depth, but cost is the loudest complaint across Reddit and review sites.11 |
| Biggest gotcha | Ingest-volume pricing: logging more data multiplies cost; budget surprises are common without active cost controls.⁶ | Multi-dimensional billing: hosts, logs, APM, synthetics each metered separately15 |
