VPN and ZTNA are not the same product
| Traditional VPN | Zero Trust Network Access | |
|---|---|---|
| Grants access to | The network | Specific applications |
| Trust model | Authenticate once, then trusted | Verify continuously, per resource |
| If a device is compromised | Attacker can scan the whole network | Attacker reaches only that user’s permitted apps |
| Traffic path | Hairpins through a concentrator | Direct, often peer-to-peer |
| Typical performance | Bottlenecked at the gateway | Near line rate |
| Onboarding a user | Client config, certificates, firewall rules | SSO login |
The main security difference is the scope of access. Once a device joins a traditional VPN, it can reach anything allowed by the network routes. That creates room for lateral movement after an attacker gains an initial foothold, especially on a flat network.
There is an operational concern as well. VPN concentrators from several vendors have had critical vulnerabilities exploited in the wild. They are attractive targets because they are internet-facing appliances that terminate trusted access, so reducing dependence on one limits a consequential point of failure.
The platforms
Tailscale
Easiest to deploy for technical teams
A WireGuard-based mesh that connects devices directly and authenticates through an existing identity provider. A small deployment can be running in minutes.
Tailscale builds a peer-to-peer WireGuard mesh, allowing traffic to travel directly between devices instead of through a central concentrator. It handles NAT traversal without inbound firewall rules, and a gateway does not become the throughput bottleneck. Authentication can run through Google, Microsoft, Okta or GitHub, avoiding a separate set of VPN credentials.
Access rules live in a versioned policy file. That model works well for teams comfortable with configuration as code, but it is less convenient for administrators who want a point-and-click console. Subnet routers and exit nodes cover cases that require access to an entire network. Tailscale is the product on this list that we use ourselves.
Strengths
- Fastest setup in the category; a small deployment takes minutes, not days
- Peer-to-peer traffic avoids a central throughput bottleneck
- No inbound firewall rules or public gateway to attack
- Generous free tier, with MagicDNS and SSH access included
Trade-offs
- ACL policy file is code, which suits some teams and not others
- Requires a client on every device; it is not clientless
- Coordination server is hosted by Tailscale unless you self-host Headscale
Twingate
Best ZTNA for mixed technical and non-technical users
Application-level access with a management console aimed at IT administrators rather than engineers, and no public gateway to expose.
Twingate connectors make outbound connections only, leaving no listening port on the internet. Access is assigned by resource rather than by network, and the admin console is designed for people who manage users without wanting to maintain policy files.
The service integrates with common identity providers and supports posture checks such as disk encryption or a running EDR agent. For an IT team serving both engineers and non-technical staff, that administration model may fit better than Tailscale even where their capabilities overlap.
Strengths
- No public gateway because connectors dial out only
- Resource-level access control with a clear admin UI
- Device posture checks before access is granted
- Straightforward for non-technical end users
Trade-offs
- Connectors to deploy and maintain
- Per-user cost higher than Tailscale
- Less flexible than raw WireGuard for unusual topologies
Cloudflare Zero Trust (Access + WARP)
Best for clientless browser access
Publishes internal web applications through Cloudflare’s network with SSO in front, so contractors and partners reach them in a browser with no client installed.
Clientless access is the distinguishing feature. You can publish an internal application behind Cloudflare Access, put your identity provider in front of it, and let a contractor connect through a browser without receiving network access. That narrower grant is preferable to issuing broad VPN credentials to third parties.
The same service can add DNS filtering, browser isolation and CASB features. The trade-off is concentration: much of the access path then depends on Cloudflare, whose outages are uncommon but affect many customers at once.
Strengths
- Clientless browser access is ideal for contractors
- Free for up to 50 users
- Integrates DNS filtering and browser isolation
- Large global network with good latency almost everywhere
Trade-offs
- Non-HTTP applications need the WARP client anyway
- Meaningful dependency on a single provider
- Configuration model takes some learning
Perimeter 81 (Check Point Harmony SASE)
Best when you need dedicated static IPs
A managed cloud VPN with dedicated gateways and static IP addresses, suited to third-party systems that require connections from a fixed address.
Payment processors, banking portals, partner APIs and older on-premises systems may still require a static source IP. A dedicated cloud gateway gives a distributed team that fixed address; this is the clearest reason to choose the product over pure ZTNA.
The architecture remains closer to a modernised VPN than to strict zero trust: segmentation is available, but network-level access is the default. Check Point has folded Perimeter 81 into a broader SASE offering since the acquisition, so confirm the current packaging and pricing directly.
Strengths
- Dedicated static IPs for allowlisting
- Fully managed, with no gateway hardware to maintain
- Network segmentation and 2FA included
- Broad protocol support
Trade-offs
- Traffic hairpins through a gateway, adding latency
- Gateway fees on top of per-user pricing
- Closer to managed VPN than true zero trust
Self-hosted WireGuard
Cheapest, if you have the skills
WireGuard itself is free, fast and in the Linux kernel. What you are buying from the products above is key distribution, identity integration and access control.
For three engineers connecting to a handful of servers, a WireGuard peer on a small VPS can be enough. The protocol is fast, modern and auditable, with about 4,000 lines of code compared with hundreds of thousands in legacy IPsec stacks.
The protocol does not provide the surrounding access-management layer: SSO, per-user policy, device posture, audit logging or key rotation when someone leaves. Tailscale and Twingate supply those controls, which become increasingly useful at around ten users. Tools such as wg-easy and Netbird occupy the middle ground.
Strengths
- Free, fast and cryptographically modern
- No vendor dependency at all
- Full control over the entire path
Trade-offs
- Manual key distribution does not scale
- No SSO, audit trail or device posture
- Offboarding is a manual configuration change on every peer
- You own uptime, patching and recovery
Comparison at a glance
| Platform | Model | Free tier | Best for |
|---|---|---|---|
| Tailscale | WireGuard mesh | Up to 3 users | Technical teams |
| Twingate | ZTNA with connectors | Small teams | Mixed user populations |
| Cloudflare Zero Trust | ZTNA + clientless | Up to 50 users | Contractor access |
| Perimeter 81 | Managed cloud VPN | No | Static IP requirements |
| Self-hosted WireGuard | DIY VPN | Free | Small technical teams |

Business VPN is not the same as a consumer VPN
The shared name causes confusion, but the two products address different requirements.
- Consumer VPN (NordVPN, ExpressVPN, Proton) routes your internet traffic through the provider so your ISP and local network cannot see it, and websites see the provider’s IP. It gives you no access to anything of yours.
- Business VPN / ZTNA connects you to your private resources, such as internal applications, databases and servers. That is usually the requirement behind "I need a VPN to work from home".
Some vendors sell "teams" versions of consumer products, which are consumer VPNs with centralised billing. If the requirement is reaching internal systems, that is not the product.
What to check before buying
- Identity provider integration. Look for SSO and SCIM provisioning. Without SCIM, offboarding remains a manual step that can leave former employees with access.
- Device posture checks. Can you require disk encryption, OS patch level or a running EDR agent before granting access?
- Audit logging. Who connected to what, and when. You will need this for SOC 2 and for any incident investigation.
- Split tunnelling control. Routing all internet traffic through a gateway is slow and usually unnecessary. Routing none of it can bypass your DNS filtering. Decide deliberately.
- What happens when the control plane is down. Do existing sessions survive? Can new ones be established? Ask, because vendors differ substantially.
- Non-HTTP protocol support. SSH, RDP, database connections and internal DNS. Clientless browser access covers web applications only.
Frequently asked questions
What is the difference between a business VPN and a consumer VPN?
A consumer VPN routes your internet traffic through a provider to hide it from your ISP and change your apparent location. A business VPN or ZTNA connects you to your organization’s private resources. They solve entirely different problems, and a consumer product will not give remote staff access to internal systems.
Is ZTNA better than a VPN?
For remote access to applications, generally yes. ZTNA grants access to specific resources rather than the whole network, so a compromised device or credential does not enable lateral movement. It also avoids exposing an internet-facing gateway. Traditional VPN still has a place for site-to-site links and legacy protocols.
How much does a business VPN cost?
Roughly $6–$15 per user per month for most ZTNA platforms, with meaningful free tiers at Tailscale, Twingate and Cloudflare. Products offering dedicated static IPs add a gateway fee. Self-hosted WireGuard costs only the server, but consumes engineering time that usually exceeds the license saving above about ten users.
Do I still need a VPN if everything is in the cloud?
Often not, provided your SaaS applications use SSO with MFA and conditional access. Databases, admin interfaces, internal tools and SSH endpoints may still need private access. ZTNA can cover that narrower requirement without placing users on the full network.
Is WireGuard secure enough for business use?
Yes. WireGuard uses modern cryptography, has been formally reviewed, and has a much smaller codebase than legacy IPsec implementations. Tailscale and several other commercial products build on it. The operational gap is around the protocol: key management, identity and access control.
What is split tunnelling and should I use it?
Split tunnelling sends only traffic destined for private resources through the VPN, leaving general internet traffic to go directly. It is faster and reduces bandwidth costs, and it is the sensible default. Full tunnelling is preferable when you want all traffic subject to corporate DNS filtering and inspection.
