5+ Gbps from a laptop

Most VPNs choke the moment you ask them to move real data. Firezone’s data plane is written in Rust, built on WireGuard®, and tuned for each operating system, so devices connect straight to the nearest Gateway and the link, not the software, sets the limit.

How the architecture works
Throughput by platform, as testedCommodity hardwareTuned hardware
Linux
5+ Gbps, 10+ Gbps on tuned hardware
macOS
5+ Gbps
Windows
5+ Gbps
iOS
2+ Gbps
Android

Throughput varies with round-trip latency, packet loss, hardware, network capacity, and workload.

Secure without the hassle

Attackers can’t attack what they can’t see. Firezone hides your network, ties access to your identity provider, and turns away every device you don’t own.

Invisible to the internet

Gateways only make outbound connections. They never listen for traffic from the internet, so there are no open ports to find and nothing to attack. You don’t touch your firewall at all. If a direct path isn’t possible, traffic goes through the nearest of 34 relay clusters, so it stays fast on any network.

How NAT traversal works

you@laptop: ~

$ nmap -Pn -p- gateway.corp.example
Starting Nmap 7.95
Nmap scan report for gateway.corp.example
All 65535 scanned ports are in ignored states.
Not shown: 65535 filtered tcp ports (no-response)

Nmap done: 1 IP address (1 host up)
  1. Oktadana@corp.example deactivated
  2. FirezoneIdentity deleted
  3. FirezoneSigned out of 3 Clients
  4. FirezoneTunnels to 12 Resources closed

People who leave lose access

Firezone syncs users and groups from Okta, Entra ID, and Google Workspace. Deactivate someone there and they’re signed out of every device. There’s no second list to clean up.

Only your devices get in

Your MDM gives each laptop a certificate whose key can’t leave the machine. Turn it on and a stolen password on a personal laptop gets nowhere.

Set up device trust

Every connection gets checked

Passing one login check once isn’t enough. Before a single packet gets through, Firezone asks who you are, which device you’re on, and whether it’s healthy. Intune, Defender, SentinelOne, and others report the answers.

Start with ready-made checks like disk encryption and an up-to-date OS. When you need something specific, write the rule in JSON.

Know who accessed what

When something looks off, you want answers, not guesses. Firezone logs every sign-in, admin change, API call, and network flow, on every plan. Each flow shows who connected, from which device, to what, and how much data moved. Both ends of the tunnel report it, so faked numbers stand out.

Pull logs from the API, or on Business and Enterprise, stream them to your SIEM.

connections secured, and counting

Each one an authenticated, encrypted WireGuard® tunnel before a single packet moved.

Thousands

of organizations trust Firezone

to keep them secure.

Simple to roll out

A Gateway is a small Linux binary that ends your WireGuard® tunnels. Run it next to your resources with a token and you’re done. Most teams are set up in under ten minutes.

# docker-compose.yml
services:
  firezone-gateway:
    image: ghcr.io/firezone/gateway:1
    environment:
      FIREZONE_TOKEN: <token>
    # Networking options are in the Docker guide
Deploy your first Gateway

Clients for every device your team uses

10 s
to fail over to a healthy Gateway in the same Site
Fresh keys
on every sign-in, and they never leave device memory

Already have a VPN? You already know Firezone

The ideas are the same, only the names change. Here is what everything is called on the Firezone side.

  1. Run side by side

    Deploy a Gateway next to your resources. Your old VPN keeps working.

  2. Recreate access

    Add Resources and Policies for the same people and servers.

  3. Move people over

    Install the Client, sign in, and switch off the old tunnel.

Teams that switched

“At Strong Compute, we have been using Firezone for over 3 years and it is still the most stable and best VPN solution we tested for remote access.”
Cian ByrneFounding Engineer, Strong Compute
“When producing live broadcasts for Fortune 500 companies security is of the utmost importance. We therefore selected Firezone for its robust WireGuard-based architecture. The flexible policy system and simple & clean user experience make Firezone the best fitting product for us in the market after trying several other solutions like Tailscale, OpenVPN, and Nebula.”
Robert BuismanCEO, NOMOBO
“Firezone's easy-to-setup, sleek, and simple interface makes management effortless. It perfectly met our zero-trust security needs without the complexity found in other products we tested.”
Mark SimTechnical Account Manager, Beakon
“After comparing Tailscale, we ultimately chose Firezone to secure access to our data warehouses. Firezone's ease of configuration and robust policy-based access system made it the clear choice for our needs.”
James WinegarCEO, Corrdyn

Works with what you already use

No rip and replace. Plug in your identity provider, MDM, endpoint security, and SIEM, then manage the rest as code with Terraform or the REST API.

Open source, so you can check our work

How can you trust a zero trust product if you cannot read its code? Firezone is built in the open on GitHub, from the Clients and Gateways to the control plane.
