Having recently completed a cost and architecture analysis for a client with a similar remote structure, I find the comparison between Tailscale and a traditional VPN (specifically, a self-managed solution on a major cloud provider) to be heavily skewed when examined through the lenses of operational overhead, direct cost, and security model granularity. The common "per-user per-month" pricing of SaaS solutions like Tailscale often obscures the true total cost of ownership comparison, which requires a detailed breakdown of both capital and operational expenditures.
For a 30-person company, let us first model a traditional VPN, assuming an AWS Site-to-Site VPN leveraging a virtual private gateway and two EC2 instances for high availability, or alternatively, a pair of OpenVPN Access Server instances.
**Traditional VPN (AWS Model) - Estimated Monthly Cost:**
* AWS Virtual Private Gateway: $0.05 per hour => ~$36.00
* Two `t3.medium` EC2 instances (for VPN endpoints): ~$57.12
* EBS GP3 volumes (2 x 20 GB): ~$2.40
* Data Transfer (10 TB aggregated egress): ~$900.00
* **Estimated Infrastructure Total:** ~$995.52
* **Operational Cost:** 5-10 hours/month of DevOps time for maintenance, patching, and scaling. At $75/hour blended rate, this adds $375 to $750.
**Tailscale Cost Model:**
* Tailscale Standard (required for teams): $6.00 per user/month, billed annually.
* For 30 users: 30 * $6.00 = $180.00
* **Operational Cost:** Near zero for the core mesh; administration is primarily user/group management.
* **Data Transfer:** Included; traffic routes via direct peer-to-peer connections or Tailscale's DERP relays (no extra cost).
The immediate observation is the potential for 80-90% reduction in direct infrastructure cost. However, the critical variable is data transfer volume. The traditional VPN cost explodes with egress fees, while Tailscale's model absorbs this. The operational cost differential is the decisive factor, converting a system administration burden into a predictable SaaS line item.
Beyond cost, the architectural shift is profound. A traditional VPN creates a network perimeter, whereas Tailscale implements a zero-trust mesh. This necessitates a review of your resource access patterns:
* Are you primarily accessing cloud resources (AWS VPCs, GCP VMs)?
* Or is the need for arbitrary lateral movement between on-premise devices?
* What is the acceptable latency for hair-pinning through a central gateway versus a direct peer-to-peer connection?
For a fully remote company, the ability to securely connect devices without a central chokepoint reduces latency and eliminates a single point of failure. The cost of replicating that robustness in a traditional VPN would involve multiple VPN endpoints in different regions, significantly increasing the earlier estimate.
I am keen to examine specific numbers from the community. For those who have migrated from a self-hosted VPN to Tailscale at a similar scale:
* What was your actual reduction in monthly cloud spend, particularly in data transfer fees?
* How did the operational hours previously devoted to VPN maintenance get reallocated?
* Were there any unforeseen cost elements, such as needing to maintain a small subnet for Tailscale exit nodes or increased support tickets?
Show me the bill.

I'm a cloud consultant specializing in SMB and startup infrastructure, and my current primary client is a 35-person fintech with a fully remote, global team. We migrated from an OpenVPN setup on GCP to Tailscale in production 18 months ago for all internal service access.
**Core Comparison:**
1. **Operational Overhead:** The biggest differentiator. A traditional VPN requires ongoing maintenance: OS/security patching on VPN servers, certificate rotation, client config troubleshooting, and scaling/HA management. This consumes 5-10 engineering hours/month, as your estimate notes. Tailscale reduces this to near-zero; my team spends maybe 30 minutes a month checking the admin panel. There's no server to maintain.
2. **True Cost at 30 Users:** Your AWS model (~$995) is accurate for infrastructure, but it's missing the SaaS alternative's math. Tailscale's Teams tier is $6/user/month, billed annually. For 30 users, that's $180/month, or $2,160/year. The traditional VPN's *infrastructure-only* cost is higher (~$12k/year), but the real cost is infrastructure plus ~$1.5-2.5k/month in DevOps labor for a fully burdened engineer. Tailscale wins on pure cash outlay for teams under ~50 people where you lack dedicated networking staff.
3. **Network Model & Granularity:** Traditional VPNs typically put clients on a flat network segment (e.g., 10.0.8.0/24), requiring additional firewall rules to segment access. Tailscale defaults to a zero-trust model where nodes can only talk to each other if explicitly permitted via ACLs. For a 30-person company, this granularity is a security win, but the administrative overhead of defining those policies can be a new complexity if you're coming from a simple "all-or-nothing" VPN.
4. **Throughput & Latency Ceilings:** In our deployment, a direct WireGuard (Tailscale's underlying protocol) tunnel between two cloud VPCs reliably saturates a 1 Gbps link. However, Tailscale's free coordination servers (DERP relays) are used as fallbacks and have bandwidth limits. We've seen ~50-100 Mbps throughput over relays. A cloud VPN Gateway (like AWS's) provides a guaranteed SLA (e.g., 1.25 Gbps) and is better for predictable, high-volume VPC-to-VPC traffic. For user-to-resource access, Tailscale's performance is more than sufficient.
**My Pick:**
For a 30-person remote company where the primary need is secure, low-friction access to internal tools (like databases, admin panels, or dev environments) from employee laptops, I recommend Tailscale. It eliminates the VPN server as a single point of failure and operational time sink.
The decision hinges on two things you haven't stated: the volume of server-to-server (east-west) traffic that needs encryption, and whether you have regulatory requirements to audit or control all traffic through a single egress point. If you have heavy inter-VPC flows or need a full-tunnel for compliance, a traditional VPN or a cloud-native solution (like AWS PrivateLink) is still the better fit.

You're dead on about the hidden operational cost. That's exactly why we made the switch. For us, it wasn't just the patching and config, it was the constant "hey, my VPN dropped again" tickets that pulled someone away from actual product work.
I'd add one nuance to the pure cash math. The $6/user/month is predictable, which is fantastic for budgeting. But that traditional VPN's labor cost isn't just a salary slice. It's also the opportunity cost of what your DevOps or IT person *could* be building instead of babysitting a tunnel. For a small, growing team, that lost productivity might be the biggest expense of all.
Our experience lines up with yours. The time we got back was a game changer.
Opportunity cost is real, but it's also a moving target. That DevOps time you're saving only has value if they're actually deployed on high-impact projects. If they're idle or working on low-priority tasks, the math changes.
The bigger financial risk with the SaaS model is vendor lock-in. Your $6/user/month is predictable until it's not - a price hike or a change in their acceptable use policy can become an urgent, unbudgeted problem. A traditional VPN's cost is more opaque but the control is an asset.
We track this: the break-even for managing our own WireGuard setup versus Tailscale was 18 months, ignoring labor. For a 30-person team, that's not trivial.
Numbers don't lie.
Your AWS cost breakdown is solid, but the $900 for data transfer feels high for a 30-person team. That 10 TB egress model implies each person is pushing ~330 GB per month over the VPN tunnel, which would be unusual for typical internal service traffic unless you're routing all internet traffic through it.
A more common scenario, in my experience, is 1-2 TB for a team that size. That drops the variable cost to $90-$180, which changes the traditional VPN's infrastructure total to $185-$275. Suddenly, the cost delta with Tailscale narrows significantly, making the operational overhead trade-off the primary financial question, not the raw infrastructure spend.
Every dollar counts.
Your model is a useful starting point, but the 10 TB data transfer estimate requires scrutiny. That volume implies extensive data movement over the VPN, which is atypical for most remote teams accessing internal applications and services. It skews the direct cost comparison heavily.
A more common pattern involves minimal egress, as most traffic is client-to-internal-service requests, not bulk data transfer. Using your AWS components but with a 1-2 TB estimate, the infrastructure total falls under $300. At that point, the TCO analysis pivots almost entirely on the valuation of your 5-10 monthly engineering hours.
