The short version

  • Only Tailscale has a free tier, so it costs nothing to try first.
  • Each has a real cost: Splunk no prices are published on any plan; every model requires contacting sales for an estimate; Tailscale requires active configuration and management; cannot be deployed passively like consumer VPNs
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Splunk

  • No prices are published on any plan; every model requires contacting sales for an estimate
  • Three separate pricing models, workload, ingest and entity, so the same deployment costs different amounts depending on which was signed
  • Ingest pricing bills on data volume, so cost tracks how much you log rather than how much value you get from it
  • Security, observability and platform are priced separately

Tailscale

  • Requires active configuration and management; cannot be deployed passively like consumer VPNs
  • Device posture policies and JIT access tiers are locked behind Premium subscription (£18/month), raising per-user costs for enterprises
  • Limited support for legacy protocols and non-modern operating systems (Windows 7, older Android versions)
  • Centralised control plane operated by Tailscale (hosted in US); no self-hosted control plane option for air-gapped or sovereign deployments
  • Cannot replace full VPN functionality for accessing legacy IP-based services; only applicable to modern infrastructure

Answered from the vendors’ own pages

Splunk: What is Splunk's pricing model?

Splunk offers activity-based, ingest, or workload pricing options depending on the product. Splunk Observability Cloud and AppDynamics use per-host or per-vCPU monthly pricing billed annually. Splunk Cloud Platform and Splunk Enterprise require custom quotes from sales.

Source
Tailscale: Is Tailscale free?

Tailscale Personal tier is free forever for up to 6 users. Standard (£8/month per user) adds team features, Premium (£18/month per user) adds security controls, and Enterprise tiers are custom priced.

Source
Splunk: How much does Splunk Enterprise cost?

Splunk Enterprise pricing requires contact with sales. The vendor offers data-ingest or workload pricing options, supports unlimited users, and can scale to petabytes of data, but specific rates are not published online.

Source
Tailscale: Does Tailscale route all traffic through a central gateway?

No. Tailscale creates direct encrypted connections between devices using WireGuard. It only proxies traffic when direct peer connections are not possible (some restrictive NAT scenarios). This reduces latency and eliminates VPN gateway bottlenecks.

Source
Splunk: What are the differences between Splunk's pricing options?

Splunk offers multiple pricing models: ingest-based pricing charges according to data volume brought into the system; workload-based pricing charges based on computing resources consumed by workloads. Both models apply to Splunk Enterprise and Splunk Cloud Platform. Standard support is included with product purchases; premium support is available as an add-on.

Source
Tailscale: Can I host Tailscale on-premises?

No. Tailscale provides a hosted control plane only. For fully self-hosted mesh networking, consider WireGuard with manual key management or Netmaker. Tailscale Enterprise can provide custom deployments for specific requirements.
