AI that defendsevery device.
CeyNox watches every Windows, Linux and macOS device for any attack, AI-driven or not, and acts on its own in milliseconds.
The proof: a malicious package ran on a Dev server and was contained 145 ms later.
It sees the attack.It acts on its own.
Sees
An agent on every Windows, Linux and macOS device watches processes, network, DNS, files and sign-ins.
Judges
Its AI investigates what the agent sees, attack by attack, AI-driven or not, and learns each device’s normal.
Acts
Its agents freeze, stop, quarantine, block or isolate on their own, within limits you set.
One attack,stopped in 145 ms.
A malicious package ran on a server during a test. Here is what CeyNox did, on its own.
5.4s
to read it
It spotted the package.
A Python package was installed on a Dev server. CeyNox’s AI read its code and found it was built to steal secrets, send them out and take remote commands.
239ms
to lock it away
It locked it away.
The agent quarantined the installed package on its own. One click puts it back.
145ms
to shut it down, after the script started
It stopped it running.
Then a script on the server imported a second copy of the package, still on disk where it was installed from. CeyNox paused the script the instant it started, then killed it and cut the server off the network, all within 145 ms.
Case: Dev server
Handled on its own- Paused the script the instant it started
- Killed the script, and the shell that launched it
- Cut the server off the network
- Confirmed: no outbound connection was made
145 ms from start to finish. Every action can be undone.
You set the limits.
Five levels, from watching to acting alone. Every action is logged and can be undone.
Observe only
It investigates and explains. It never changes anything.
Ask before acting
It suggests every action and waits for your yes. Only a reversible freeze of a process running confirmed malware happens on its own.
Block known threats
It also blocks destinations that threat intelligence lists as malicious. Everything else waits for you.
Act on high-confidence threats
It also acts on threats it confirms, such as quarantining a package its AI found malicious. Stopping python3 and cutting a server off still wait for you.
Fully autonomous
It acts on its own, network isolation included, within limits you set. The test ran at this level.
Questionsabout CeyNox
What is CeyNox?
CeyNox Security is AI-native endpoint security from CeyNova Labs for Windows, Linux and macOS. An agent on each device sees processes, network, DNS, files and sign-ins; its AI investigates what it finds, whether the attack is AI-driven or not, and its agents act on their own within limits you set: freezing or stopping processes, quarantining files, blocking connections and isolating a host.
What if the AI gets it wrong, or will not review?
A verdict is confirmed when the model has read the code and is sure, or when the model says malicious and CeyNox’s own scanner finds all three signs: it reaches for secrets, sends data out and hides how it runs. If the AI provider declines to review, the scanner decides on those findings. Every action has Undo, and Restore puts quarantined files back.
Can we run it on our own infrastructure?
Yes. You can run CeyNox on your own infrastructure, or we can host it for you. Separately, its AI can run on Claude or on models you host yourself.
What happens to our security data?
It is used only to protect your systems, and we never sell data. Run CeyNox on your own infrastructure with its AI on models you host yourself, and it never leaves your environment.
Can we use it now?
