WireGuard vs Tailscale for Small Business: When to Self-Host and When to Pay

Transparency note: This article is based on my own professional deployments and currently contains no paid or affiliate links. If that changes, this notice and the affiliate disclosure will say so.

Two years ago I had to connect hospital servers across several sites after two national telecom providers failed to deliver a working MPLS link. Not “delivered late.” Failed. The link either never came up or fell over under load, and patients’ records still had to move between facilities every day.

I ended up building the whole thing on plain WireGuard. It has been running since. So when people ask me whether they should use raw WireGuard or pay for Tailscale, I’m not answering from a comparison table. I’ve lived with one of these in production, and I’ve deployed the other for clients who had no business managing VPN configs themselves.

The short version: WireGuard is the engine, Tailscale is the car built around that engine. Whether you should buy the car or build your own depends on exactly one question, and it isn’t a technical one. It’s this: who fixes it at 2 a.m. when a site drops?

What WireGuard actually is

WireGuard is a VPN protocol baked into the Linux kernel. Around 4,000 lines of code, compared to hundreds of thousands in OpenVPN or IPsec. Less code means fewer bugs, faster handshakes, and throughput that makes older VPNs look silly. On the hospital links I regularly see WireGuard saturate the underlying connection; the VPN is never the bottleneck.

But WireGuard by itself gives you nothing except the tunnel. No user management. No key distribution. No NAT traversal magic. You generate keys by hand, exchange public keys between peers, assign IPs from your own addressing plan, and write config files on every node. Add a tenth site and you’re editing ten configs.

For my hospital deployment that was fine. The topology is stable, sites don’t come and go, and I wanted full control over routing because medical data crossing borders has compliance implications. I know exactly which packet takes which path, because I wrote every line that decides it.

What Tailscale adds on top

Tailscale takes the WireGuard protocol and wraps it in a coordination layer. You install the client, log in with a Google or Microsoft account, and every device you’ve authorized can see every other device. Behind CGNAT? It punches through. Both peers behind NAT? Its DERP relays handle it. New laptop joins the team? Install, log in, done. No config files, no key ceremony.

That NAT traversal point deserves a pause. I’ve deployed Starlink in dozens of rural communities, and Starlink puts users behind carrier-grade NAT, which breaks traditional inbound VPN setups completely. Raw WireGuard through CGNAT requires a publicly reachable node to act as a hub. Tailscale handles the same situation with zero configuration. If your sites are on Starlink or mobile LTE connections, that alone can decide the question.

Pricing changed in April 2026 and got simpler: the free Personal plan now covers up to 6 users with unlimited devices, which is genuinely generous. Business plans are seat-based: Standard at $8 per user per month and Premium at $18 per user per month, the latter adding SSO, advanced access controls, and audit features.

Where raw WireGuard wins

Cost at scale. WireGuard is free forever, for any number of nodes. A business connecting 40 people pays Tailscale per seat monthly, every month. My hospital setup costs exactly the price of one small VPS acting as the hub: a basic KVM machine in the $5-per-month range from Hostinger’s VPS line is plenty for a WireGuard hub serving multiple sites.

No third-party dependency. Tailscale’s coordination servers sit in the login path. If Tailscale the company has an outage, new connections can fail (existing tunnels usually survive). For a hospital, “usually” wasn’t a word I could put in a proposal.

Compliance and data sovereignty. With plain WireGuard, no external company knows your network topology. Some regulated industries require exactly that.

It teaches you networking. Setting up WireGuard manually forces you to understand routing, NAT, and firewalling. If you’re an IT professional, that knowledge compounds. Tailscale hides it.

Where Tailscale wins

Time. My WireGuard deployment took days of planning: addressing scheme, key management, failover, firewall rules on every node, and documentation so someone other than me could maintain it. A Tailscale network for the same sites takes under an hour.

People who leave. In a company, staff turnover is a security event. With raw WireGuard, offboarding means removing keys from every relevant peer and hoping you didn’t miss one. With Tailscale you disable the account in your identity provider and every session dies at once.

Roaming users. WireGuard site-to-site is elegant. WireGuard for 15 laptops that move between home, office, and airport Wi-Fi is a support burden. Tailscale was built for exactly that case.

CGNAT and messy networks. Covered above, but it’s worth repeating: if you can’t get a public IP at your sites, Tailscale removes a whole category of pain.

My actual recommendation

Ask the 2 a.m. question honestly.

If your business has a real network person on staff (or on retainer), your topology is mostly fixed sites, and monthly per-seat fees offend you, build it on raw WireGuard with a small VPS as hub. You’ll own every part of it. That’s what I did for the hospitals, and I’d do it again. My Hostinger review covers the hosting side of that setup, including the VPS tier.

If nobody on the team wants to read routing tables, if your people work from laptops in changing locations, or if your sites sit behind Starlink or mobile CGNAT, use Tailscale and don’t feel bad about it. Paying a vendor so that offboarding an employee takes one click is not laziness. It’s risk management. And with the free plan now covering 6 users with unlimited devices, a small team can run on it indefinitely without paying anything.

There’s also a middle path I use for some clients: Tailscale for the roaming laptops, plain WireGuard for the fixed site-to-site backbone. The two coexist fine since it’s the same protocol underneath.

FAQ

Is Tailscale as secure as WireGuard?

The tunnel encryption is identical, because it IS WireGuard. The difference is trust: with Tailscale you’re trusting their coordination layer and your identity provider. Their design keeps private keys on your devices, so they can’t decrypt your traffic, but they do orchestrate who connects to whom.

Can I self-host the Tailscale control plane?

Yes, there’s an open-source implementation called Headscale. It works, but now you’re maintaining a coordination server too, which cancels much of the reason to use Tailscale. I’d only go there for lab or compliance-driven cases.

What about performance?

Same protocol, so direct connections perform the same. When Tailscale falls back to DERP relays (when NAT punching fails), speed drops noticeably. Raw WireGuard through your own hub gives predictable performance because you chose where the hub lives.
