The AI firewall operating system
El Cubo reads every name, every handshake and every download, and decides with Daisec, its next-generation AI antivirus, before a packet reaches your network.
The next-generation firewall, rebuilt from the operating system up
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
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.
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.
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.
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.
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.
Files are judged as they arrive by Daisec, the next-generation AI antivirus that runs 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
Categories, lists and your own rules, enforced on every device whether or not it plays by the rules.
How filtering worksDownloads
Documents, installers, archives and scripts, decided by the next-generation AI antivirus on the box, with the reason spelled out.
How scanning worksIntrusions
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 worksTunnels
Laptops, phones, branch offices and clouds join the same protected network with the VPN client their operating system already has.
How connecting worksZero-days
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 Daisec judgesWhy the incumbents will struggle
Without this, the legacy appliance becomes a fast switch with an expensive subscription. With it, the network defends itself.
Updates
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 workRAM 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.
Daisec
Daisec is the intelligence inside El Cubo. Its models for files, names and beacons run on the box itself and judge what they see, and every malicious verdict comes with an explanation a person can read. Daisec updates itself, and a box that is cut off from the world keeps deciding with the models it has.
