The short version

  • Only Tailscale has a free tier, so it costs nothing to try first.
  • Each has a real cost: Tailscale requires active configuration and management; cannot be deployed passively like consumer VPNs; ThousandEyes cisco does not publish a current definitive rate card, so any price a buyer finds online is likely outdated and should be confirmed directly with sales before budgeting
  • Prices and features above were last checked on 1 September 2026.

ThousandEyes

  • A network operations team at a large enterprise needing to diagnose whether a performance problem sits inside their network, with an ISP, or at the destinationnot Tailscale
  • An organisation already standardised on Cisco networking wanting internet path monitoring that integrates with existing Cisco toolingnot Tailscale
  • A company needing endpoint agent testing from real employee devices to reproduce user-reported performance issuesnot Tailscale
  • An SRE team wanting aggregated internet outage and BGP visibility across a wide customer base rather than building that dataset themselvesnot Tailscale

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

ThousandEyes

  • Cisco does not publish a current definitive rate card, so any price a buyer finds online is likely outdated and should be confirmed directly with sales before budgeting
  • A 12-month minimum contract removes the option to trial the platform under real production load on a shorter commitment
  • Unit-based consumption billing across different test types is not always intuitive to forecast, and usage can grow unpredictably as more tests and agents are added
  • Since the Cisco acquisition, purchasing now runs through Cisco's broader enterprise sales and licensing process, which can be slower and less transparent than dealing with a smaller standalone vendor
  • Deep Cisco ecosystem integration is a real advantage only for organisations already standardised on Cisco; it offers less differentiated value for a non-Cisco shop
  • Endpoint agent pricing tiers (Essentials versus Advantage) gate meaningfully different capability, and choosing the wrong tier at signup can mean a contract renegotiation to get needed features

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
ThousandEyes: Is ThousandEyes still sold as a standalone product after the Cisco acquisition?

Yes, it remains a distinct, purchasable product line rather than being merged into another Cisco offering.

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
ThousandEyes: Is there a published, current price list?

No, Cisco does not publish a definitive current rate card; historical unit prices exist online but should not be treated as confirmed 2026 pricing.

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.

Source
ThousandEyes: What is the minimum contract length?

12 months.
