The short version

  • Each has a real cost: Tailscale requires active configuration and management; cannot be deployed passively like consumer VPNs; Splunk no prices are published on any plan; every model requires contacting sales for an estimate

Where each one falls short

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

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

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

Answered from the vendors’ own pages

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
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
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.
