Fetched 2026-09-09: no Cisco/Splunk branding, markets as an independent product, "Trusted by enterprises, loved by developers."
- Deployment
-
Enterprise tier lists "Deploy: Hosted, VPC, or on-prem" -- self-hosted/private-cloud options exist at that tier, but the product is offered and metered as SaaS at Free/Pro; deployment left at ["saas"] rather than guessed further, matching the free/pro-tier evidence actually read.
