El Cubo

The router operating system that fights back

The last thing
an attack ever sees.

El Cubo reads every name, every handshake and every download, and decides with artificial intelligence before a packet reaches your network.

The next-generation firewall, rebuilt from the operating system up

The firewalls that guard the world today were designed before the attackers learned to use AI.
El Cubo was designed after.

A legacy firewall waits for a signature. El Cubo judges the thing in front of it, on the box, in the time it takes a packet to arrive. Not an old firewall with AI bolted on: a new operating system with AI inside.

An operating system for an AI-first world

Written from scratch.
Light as a feather. Thinks for itself.

0

Lines inherited

No twenty-year codebase, no acquired products stitched together, no fork of somebody else's system. Every part of El Cubo was written for this job, in this decade, on modern, memory-safe foundations.

Light

A footprint you can barely measure

Memory is the most expensive part of a device and its price keeps climbing. El Cubo was built to need very little of it: the whole operating system is a small download and runs in a fraction of the memory a legacy appliance demands. Every megabyte it does not use is margin on the box and years of life in the field.

AI

Native, not bolted on

The models are not a plug-in or a cloud subscription. They live in the data path, where the packet is, and every decision the system makes can take their verdict into account in real time.

01

It reads the name on the door.

Every question a device asks the internet passes through El Cubo first. A name in a blocked category, or on your own list, is turned away before a single connection opens. Whole categories, tens of millions of names, refreshed daily.

02

It reads the handshake.

A device that resolved a name elsewhere still has to say it out loud when it connects. El Cubo listens for that moment and refuses the handshake. Encrypted DNS, hidden resolvers and the usual bypasses are closed the same way.

03

It reads the download.

Files are judged as they arrive, by models that run on the box itself. A malicious file never reaches the desk, and the person who asked for it sees a page that explains why, in plain words, not a browser error.

Names

Blocked at the first question.

Categories, lists and your own rules, enforced on every device whether or not it plays by the rules.

How filtering works

Downloads

Every file, judged as it arrives.

Documents, installers, archives and scripts, decided by artificial intelligence on the box, with the reason spelled out.

How scanning works

Intrusions

Patterns the packets can't hide.

Exploits, scanners, beacons and command channels are dropped in the flow, with a ruleset and models that learn the shape of an attack.

How prevention works

Tunnels

Every device. Every place. One key.

Laptops, phones, branch offices and clouds join the same protected network with the VPN client their operating system already has.

How connecting works

Zero-days

A signature needs a victim first.
El Cubo doesn't.

Every legacy firewall is blind to an attack until somebody, somewhere, has already suffered it and a vendor has written it down. El Cubo judges the file, the name and the flow in front of it by what they are and what they would do. An attack nobody has seen yet is stopped the same way as one everybody has. Day zero looks like any other day.

How the intelligence judges

Why the incumbents will struggle

Legacy firewalls bolt intelligence on.
El Cubo is built out of it.

The legacy firewall

  • Blind to a zero-day until a vendor writes the signature
  • Sends your traffic to a cloud to get a verdict
  • A client to write, sign and maintain per operating system
  • Goes dark for minutes while it updates
  • A dozen products stitched together behind one logo
  • Needs a data centre behind the box to do its job

El Cubo

  • Stops the attack nobody has seen yet, on day zero
  • Decides on the box, so nothing leaves and nothing waits
  • The VPN client every operating system already ships
  • Updates while it routes, one reboot, rolls back by itself
  • One operating system, one binary, one configuration
  • Runs on a device, a VM or a cloud, and stands on its own

Without this, the legacy appliance becomes a fast switch with an expensive subscription. With it, the network defends itself.

Updates

It updates while it routes.

A new release is written beside the running one. Nothing stops. The switch costs one reboot, taken when you choose, and a release that fails to prove itself is abandoned for the one that worked. A bad configuration cannot lock you out either: a box that loses its way reverts on its own.

How updates work

Efficiency is baked in.
Not added later.

RAM costs money and the price is rising. Legacy appliances were designed when memory was cheap and a data centre behind the box was normal. El Cubo was designed for the opposite: a small device, a small bill, and nothing behind it.

Intelligence

Decisions, not signatures.

Models for files, names and beacons run on the box itself and judge what they see. Every malicious verdict comes with an explanation a person can read. The models update themselves, and a box that is cut off from the world keeps deciding with the ones it has.

Meet the intelligence

Where it runs

A device, a VM, a cloud, a Mac.

  • arm64 hardware
  • amd64 hardware
  • VMware ESXi
  • KVM and Proxmox
  • Cloud droplets
  • USB and ISO
  • A VM on a Mac

The future of the firewall is an operating system.
This one.

Built for every network that would rather not be the next headline.
