The focused Aviatrix alternative — same idea, a fraction of the floor.
Aviatrix and Enforza both replace the cloud NAT gateway with a secure egress firewall, and both are flat-rate with no per-GB tax. The difference is the estate each is built for. Aviatrix is a multicloud networking platform — a transit backbone, a distributed firewall across hundreds of networks, a Kubernetes firewall — with an enterprise-shaped entry: a packaged PaaS from $27,700/year, or a Controller and CoPilot running in your account. Enforza does the NAT + FQDN-egress job from one small VM and a flat per-firewall price.
Same idea. We are honest about that.
Aviatrix got to the secure-NAT-gateway idea seriously before we did, and it is a good one. Both products swap the managed cloud NAT gateway for an appliance in your own account that adds egress control, and both are flat-rate with no per-GB data-processing tax. What differs is scope — the size of the estate each is built for.
-
Both replace the cloud NAT gateway
Aviatrix and Enforza both do the same core thing: swap the managed cloud NAT gateway for an appliance in your own account that adds secure egress control on top of the NAT. Aviatrix ran that narrative seriously before we did, and it is a genuinely good idea — we are on the same side of it.
-
Both are flat-rate, no per-GB tax
Neither product charges a per-GB data-processing fee. Aviatrix bills a flat rate per gateway-hour and Enforza a flat per-firewall licence — so unlike the cloud-native firewalls, the meter does not climb with every byte. On the pricing model everyone searches for, we agree.
-
The difference is the estate
Aviatrix is a multicloud networking and security platform, where secure egress is one capability among a transit backbone, a distributed firewall across hundreds of networks and a Kubernetes firewall. Enforza is a focused, flat-priced tool for the NAT + FQDN-egress job on one or a handful of networks. Different products for different-sized estates.
Built for a bigger estate than one small VM
Aviatrix has two ways in, and both are enterprise-shaped — because a lot comes with them. The packaged PaaS bundles implementation and 24×7 support; the self-managed route runs the platform that drives its distributed fabric. Neither is a rip-off — they are built for a larger buyer. Enforza's floor is a free tier, then one small VM and a flat per-firewall price.

Packaged PaaS: 5-Pack $27,700/yr, 10-Pack $46,800, 15-Pack $66,400 (12-month
contracts, implementation + 24×7 support included). Self-managed: Security
Services $0.23/gateway-hr and a NAT dimension $0.14/gateway-hr, plus a
Controller (~$158/mo) and CoPilot (~$347/mo) VM in your account (EC2
on-demand, us-east-1).
Both products are flat-rate with no per-GB tax — the difference is the
entry floor and the platform footprint, not per-GB metering.
The focused tool for the NAT + FQDN-egress job
If your estate needs the whole Aviatrix platform, it earns its footprint. If the job is secure egress on one or a handful of networks, a focused appliance is faster to stand up, easier to forecast and priced for it. Here is where that focus wins.
-
A floor of one small VM
Enforza's entry is a single Linux VM (a few dollars a month) plus a flat per-firewall subscription — and a genuine free tier before that. Aviatrix's cheapest packaged PaaS entry is the 5-Pack at $27,700/year, or the self-managed route with a Controller and CoPilot running in your account. It is a real, enterprise-shaped floor, built for a larger buyer than one small VM.
-
No platform footprint before the first packet
Enforza is one appliance — no controller, no copilot, nothing else to stand up before it filters traffic. The self-managed Aviatrix route runs a Controller (a c5n.xlarge, roughly $158/month) and a CoPilot (an m5n.2xlarge, roughly $347/month) in your account first. Those are the platform that makes the fabric work; Enforza simply does not have one to run.
-
Deployed in minutes, not rolled out
Enforza is a single install command on a standard Linux VM — the firewall registers itself and pulls policy from a GitHub pipeline or the console. Aviatrix is a broader platform to learn and roll out; reviewers consistently note the depth takes time to onboard. For the NAT + FQDN-egress job specifically, the focused tool gets you there faster.
-
Flat per firewall, whatever the VM
Enforza is a flat per-firewall licence — £179/month, £149 from your sixth — regardless of the VM size you run it on or how much it carries. Aviatrix meters per gateway-hour per node, and a high-availability design doubles the node count and the licence bill. One flat line is easier to forecast.
-
Compliance baked in
Enforza ships 25 framework packs and 210 CIS / NIST / PCI-mapped controls, advising or enforcing on every policy publish, with continuous audit. Aviatrix is a strong networking and security platform, but it has no equivalent compliance-controls catalogue built into the product — that evidence is on you to assemble.
-
Egress policy as a reviewed GitHub PR
Enforza's egress policy is YAML in a Git repo — every change a pull request with a line-by-line diff, CI validation and a permanent audit trail, or the same policy from the console. Aviatrix has a capable Terraform provider for provisioning and a rich console for its Distributed Cloud Firewall; Enforza's difference is the PR-reviewed egress-policy workflow on a single focused surface.
-
Self-serve on AWS Marketplace
You can start Enforza yourself — a free tier, then BYOL on AWS Marketplace and the Linux VM you provision, no sales call required. Aviatrix's PaaS packages are 12-month marketplace contracts with implementation services bundled — a great fit for a procurement-led enterprise buy, a heavier lift for a team that just wants to try it this afternoon.
-
A single-pass engine, purpose-built for cloud
On the same standard Linux network primitives every egress appliance uses, Enforza runs its own single-pass packet classification and verdict engine: each flow is classified once, in microseconds (measured p99 49.5 µs), then enforced in-kernel at line rate, 98.5% on the kernel fast path. Microsecond-class, purpose-built for cloud egress and east-west.

Where each one fits
Where Enforza wins
- A floor of one small VM — a free tier, then a Linux VM plus a flat subscription, rather than a $27,700/year packaged entry or a controller-and-copilot footprint.
- No platform to run before the firewall works — one appliance, no Controller and no CoPilot VM standing in your account before the first packet is filtered.
- Deployed in minutes — one install command, self-registering, policy from a GitHub pipeline or the console; the focused tool for the NAT + FQDN-egress job.
- Flat and forecastable — one per-firewall line whatever the VM size, not per-gateway-hour metering that a high-availability design doubles.
- Compliance is first-class — 25 framework packs and 210 CIS / NIST / PCI-mapped controls with continuous audit, advise-or-enforce on every publish.
- Self-serve from the start — a genuine free tier and BYOL on AWS Marketplace, no 12-month contract or implementation engagement to begin.
When Aviatrix is the right call
- You run a large multi-cloud estate — many networks across AWS, Azure and Google Cloud, plus edge and on-prem — and want one distributed policy fabric and an encrypted transit backbone across all of it. That is what Aviatrix is built for, and Enforza is not.
- You need to define egress policy once and enforce it natively at every gateway across hundreds of networks, with identity-based groups rather than IP lists.
- You need a Kubernetes firewall for K8s egress and segmentation — a workload class Enforza does not address.
- You need deep, URL-path-level L7 filtering that requires TLS decryption, or server-certificate verification against the SNI — capabilities Enforza deliberately does not offer, because it never decrypts TLS or holds your keys.
- You are a procurement-led enterprise that values a 12-month contract with implementation services and 24×7 support bundled in, plus a managed PaaS control plane and enterprise references.
Aviatrix alternative — common questions
Are Enforza and Aviatrix trying to do the same thing?
On one job, yes: both replace the cloud NAT gateway with an appliance in your own account that adds secure egress control, and both are flat-rate with no per-GB data-processing tax. Aviatrix ran that narrative seriously before we did, and it is a genuinely good idea. Where they diverge is scope. Aviatrix is a multicloud networking and security platform — a transit backbone, a distributed firewall across hundreds of networks, and a Kubernetes firewall — where secure egress is one capability. Enforza is a focused, flat-priced tool for the NAT + FQDN-egress job on one or a handful of networks. Different products for different-sized estates.
What does Aviatrix cost to get started?
Aviatrix has two routes, and both are enterprise-shaped. The packaged PaaS starts at a 5-Pack for $27,700/year — one fabric, five nodes and five Advanced Security Modules, with implementation and 24×7 support included (a 10-Pack is $46,800 and a 15-Pack $66,400, on 12-month contracts). The self-managed route meters per gateway-hour — Security Services at $0.23/gateway-hour and a NAT dimension at $0.14/gateway-hour — and additionally runs a Controller and a CoPilot VM in your account. It is a real, well-supported floor built for a larger buyer. Enforza's floor is a free tier, then one small VM plus a flat per-firewall subscription. Figures are Aviatrix's own AWS Marketplace list prices, taken 2026-07-10, directional and subject to change.
Is Enforza cheaper than Aviatrix?
For the focused NAT + FQDN-egress job, and especially below the enterprise threshold, yes — the entry economics are very different. Enforza is one small VM plus a flat per-firewall licence, with a genuine free tier; Aviatrix's cheapest packaged entry is $27,700/year, or a self-managed route with a Controller and CoPilot running in your account before the first packet is filtered. Both products are flat-rate with no per-GB tax, so this is not a per-GB argument — it is about the entry floor and the platform footprint. If your estate is large enough to use the whole Aviatrix platform, that footprint earns its keep; if the job is secure egress on a few networks, Enforza is priced for it.
How do the savings claims compare?
They measure different things, so we present both as each vendor frames them. Aviatrix markets an average 25% saving against native cloud NAT gateways. Enforza's 60–80% is measured against the cloud-native firewalls (AWS Network Firewall, Azure Firewall, Google Cloud NGFW) with their per-GB data-processing charges, at modest-and-up egress volumes. They are different baselines — Aviatrix versus the NAT gateway, Enforza versus the cloud firewall — so the headline numbers are not directly comparable. Run your own figures on the savings calculator rather than trusting any single headline.
Does Enforza have a controller or copilot to run like Aviatrix?
No. Enforza is a single appliance with nothing else to stand up — no controller, no copilot, no platform tier in your account. The self-managed Aviatrix route runs a Controller (a c5n.xlarge, roughly $158/month) and a CoPilot (an m5n.2xlarge, roughly $347/month) in your account, because those are what drive its distributed fabric. That platform is exactly what makes Aviatrix powerful across a large estate; it is also overhead you carry whether or not the estate is large. Enforza does the NAT and FQDN-egress job without one.
Where is Aviatrix genuinely the better choice?
In several places, and we will not pretend otherwise. Aviatrix gives you true multicloud breadth — one distributed policy fabric and an encrypted transit backbone across AWS, Azure, Google Cloud, edge and on-prem — plus a distributed firewall enforced natively at every gateway across hundreds of networks, a Kubernetes firewall, deep URL-path L7 filtering via TLS decryption, server-certificate verification against the SNI, and built-in threat detection and geo-blocking. It also comes with enterprise procurement: 12-month contracts with implementation services and 24×7 support bundled. If your estate is large and multi-cloud, or you need those deep-inspection capabilities, Aviatrix is the right call.
Can Enforza do the deep URL-path filtering Aviatrix does?
No, and that is a deliberate design choice rather than a gap we are working to close. Aviatrix's URL-based WebGroups do full URL-path filtering by decrypting TLS — a man-in-the-middle that requires holding keys. Enforza never decrypts TLS and never holds your keys, so it filters by SNI and FQDN (the hostname) but not the URL path. If URL-path-level control is a hard requirement, Aviatrix has it and Enforza does not. If you would rather not decrypt egress traffic at all, that is exactly why Enforza works the way it does.
Does Enforza run across multiple clouds like Aviatrix?
Enforza runs on AWS, Azure, Google Cloud or on-prem, managed from one console, so a mixed estate is one fleet rather than several firewall products. What Enforza does not provide is Aviatrix's distributed networking fabric — the encrypted transit backbone, BGP and transit-gateway orchestration, and single policy enforced across hundreds of networks. Enforza places focused appliances where you need egress control; Aviatrix builds and secures the multicloud network itself. If you need the fabric, that is Aviatrix's home ground.
Is there a free way to try Enforza?
Yes. Enforza has a genuine free tier — one firewall with L3/L4 policy and network objects, no card required. A 14-day trial unlocks the full feature set, including FQDN/SNI egress filtering, compliance packs, log export and live logs. The paid plan is £179/month per firewall, dropping to £149 from your sixth, plus the Linux VM you provision, and it is available BYOL self-serve on AWS Marketplace. Aviatrix offers a trial too, but its packaged entry is a 12-month enterprise contract — a heavier commitment to begin.
